Octane boosters aren't used to boost hp, I repeat, octane boosters don't boost hp - octane boosters are used in Higher Compression Ratio engines so these engines will run properly without preignition (detonation) and 'deiseling' in carbureted engines when you turn them off - it's the higher compression that leads to the 'higher horsepower' iykwim. That's not disputable. However, if your car has a 'compression ratio' of 10 to 1 or higher and you are running premium gas of an octane rating (AKI) in the US of 91 BUT that 91 Octane rating has been achieved by adding 10% Ethanol (octane of 100) as almost all fuels in the US now have 10% Ethanol, then things get more interesting. Gallon per gallon, ethanol has about 2/3 the energy content of gasoline so, although the octane of your gas is now 91 your car will not do as much 'work' with the 'gallon' of an ethanol blended gasoline to the 'gallon' of similar octane gasoline without ethanol - in other words, it'll be less efficient (get worse gas mileage). When you boost your octane sensibly your engine, with it's fuel metering and ignition timing software, will adjust accordingly to the improved 'real' octane it is 'seeing' primarily by sensing less preignition, most of which you cannot hear, and some you might ( 'knocking' ) to improve things like 'drivability' for lack of better way to describe it . Modern, performance street cars can benefit from boosting octane to an (AKI) of 94 to 96 - higher compression, performance engines with or without superchargers from the '50's, 60's and '70's do benefit from Octane levels up to about 102 to 104 (or was that RON back then? either way that would be 97 to 99 in today's numbers) - remember when it was labeled 102 above the premium gas pumps ? - boy am I old ; P .
Higher octane gas can increase power in modern turbocharged engines like the ecoboost. The ecu is tuned to detect knock and will advance and retard timing to the fuel used to a degree. It's pretty significant. Obviously the octane does not increase power but it allows the car to modify its tune more aggressively without damaging the engine.
You should do this video again with the fuel costs from 2022. Where I live, Premium (91 octane PON) is USD$0.50 per gallon more than Regular (87 octane PON). Rislone 4747 costs $2.50 for a 6 oz bottle and claims to increase 20 gallons by 20 points (2 octane levels). Doing the math, 20 gallons of Regular is $3.33 currently, so $66.60 total. Add 2 bottles of octane booster to bring the 87 to a 91, and I'm at $71.60. 20 Gallons of Premium is $3.83 currently so $76.60. In this case, Octane Booster seems to save me $5 or about 6.5%. I think in 2016 the price difference between Regular and Premium was different, like USD$0.20 to USD$0.30 per gallon. Times change, eh?
my sentiments exactly, with gas now going $5 plus. And now in Michigan, there's a 75 cent difference per gallon from 87 to 93. I have a Wrangler 2.0 which puts out more power with premium, and a Mustang GT tuned for 92 octane, so I have 2 different examples where I'd like to know if going to a bottle solution would be sufficient and have the same effect as buying 93 octane gas.
@@robsolf I've learned a bit more with information from the octane booster manufacturers. If they state "20 points" as Rislone 4747 does, that's 2 octane. However, doubling the additive does not yield another 2 octane, and can cause problems in the fuel with MMT fouling. I do think that modern engines in cars is different than my use in a 2-stroke engine, so octane booster in cars that need premium to run correctly is a viable option, as long as the octane booster can increase your octane enough as stated on the bottle, e.g. 89 to 91 for an octane booster that claims 20 points.
In turbo charged cars especially when it's boosted over the factory limit it's almost a necessity and it does actually give you noticeable horsepower gains in turbocharged cars regular cars not so much
Higher octane is needed when either compression is high, timing is advanced, running boost etc. The higher the octane, the more aggressive tune can be ran to make more power. These scenarios create a condition where detonation can occurs and detonation destroys motors.
Yeah, I'm considering doing 10 to 1 forged pistons in mine ( A modified Saturn SL2) , with low boost, 8-10 PSI, just to get the added torque when just cruising normally around town and not having to rely as much for power all the time with boost. .I'm having the combustion chambers polished with the port and polished head job and I run premium in the car and have been for years. I suppose if I really wanted peace of mind I could always run E85 with the build and tune, etc.
Sometimes I get octane booster instead of premium or ultra because where I live 93 gas can cost about 70-80 cents more per gallon than 87 and then I can get the octane booster for around $2 - $3... but there are other areas where the better octanes prices aren't significantly more expensive than the lower octanes.
Octane is a retardant that inhibits combustion for better ignition control in high compression engines. It is used to prevent pre-ignition or detonation when combustion changer temperatures and pressure become elevated. The term "Booster" is miss leading as it does "boost" your octane level, but octane does not provide "boost" like a supercharger or turbo.
Yes! The only reason I run octane booster in my '86 Scirocco is because we did an engine swap that gave it a much high compression therefore I need more octane to counter the retardant of the engine and have it run a little smoother.
@@david-tracy No, you're still compressing a fuel air mixture. If you want to fit more in there it has to be compressed more and ignited earlier. You still need a fuel that resists detonation so you can accurately control the ignition timing.
Again, we don't care if octane does nothing for the car....just if we can use regular gas instead of premium gas with these boosters...because we have cars that says "premium fuel required"
I tried it on dyno... High octane allows you to advance spark and pump more fuel into chamber without detonation... If you know what you are doing you get more hp by octane... If you know what you are doing... I gained 8 whp by adding octane
I'm a qualified mechanic. Simply, high compression motors have to sacrifice ignition advance to counter pinging and detonation. Ignition advance often (but not always) makes power as does high compression but the fuel available often isn't compatible for both advance and high compression in modified motors. An octane booster can allow more advance on high compression motors that are modified by the USER (rather than by a highly tuned factory engine that has all that sorted by the manufacturer). It is always important to follow the manufacturers' fuel recommendations because putting low octane 91 fuel in motors designed for 98 induces what octane boosters are trying to stop. Now OEM fuel injected performance motors, It is unlikely that an octane booster is going to result in more power because the engine management computer isn't going to advance the ignition timing beyond the factory pre set ignition advance. That said it is possible to improve on factory setting by modding the computer and an octane booster may allow more power but the downside is you're stuck using an octane booster at every fill up. What some people do is tune for 98 octane pump gas when a motor was specified for lower octane fuel. Must remember the power isn't coming from the fuel or the fuel additive. On another matter, aviation fuel (Avgas) is high octane for different reasons than high compression. It is designed to resist detonation with varying power settings at varying air densities. Aviation engines are low compression but have to be able to be substantially leaned. This leaning induces detonation, as does combinations of high load, low rpm high ambient air temperature and rich mixtures. That fuel is designed for that application but can be used in automotive applications although racing fuel is better. Avgas has old school lead in it - so it can't be used with any motor that has a catalytic convertor. I had an old 4 cylinder car with no cat, that I used up the remains of several drums of Avgas in and it made absolutely no difference to it. The exhaust however went a nice mid-light grey showing me it was running well lol.
Turbos and higher compression motors can benefit from higher octane fuel. Our 2024 Mazda CX 5 has a naturally aspirated engine with a compression ratio of 14:1. That is higher than any naturally aspirated engine of this type. I definitely noticed a peppier response when I used 93 octane fuel, especially from 0-50. The gas mileage was slightly better overall, roughly an increase of 1-2 mpg combined. If your vehicle calls for 87 octane or higher as exhibited in your manual, you may receive a performance and/or an increased mileage benefit from 93 octane gas. It’s worth a try.
I have a 1971 Scamp 360 375HP. I occasionally put STP octane booster plus in her tank during fill ups. I will tell you, when I do ~ Boom! She gets up and goes, chirping wheels at every gear. Don’t know the science behind it, but I know she likes it. Moonshine for the car!
Great explanation. My car requires a higher octane fuel than what is available in my country. Is it safe to use stp octane boost which contains MMT? Would it cause harm to engine components?
So here's my question. My 2013 v6 mustang is set up with high performance. I have a tuner. 87 89 91 and above octane setting. I usually go for 93 octane with 10 percent ethanol. What if I use 87 non ethanol and put octane booster in it and still set tuner to 91 and above?Why do I do this you ask? Long term fuel storage. Don't get into the long term storage questions. Just the non ethanol with booster and tune setting questions. Thank you for whatever input you have because I realize you would have to have a level of genius beyond me
My 2013 Hyundai Accent knocks with either 87, 91 and a bit less with 93. So I decided to add Sunoco 100 to the 93 octane and it is awesome!!!! Not only I got to eliminate the knock but I have seen milage gain for daily highway and city daily driving. I did not knew that my car came with about 210psi compression and a local machine shop had many of these engines destroyed at 40k mules due to use of poor fuel and owners not hearing the knocking. so that is my take over high octane fuel vs. octane booster. as someone said before, a bottle does not take 87 to 93...
My car requires 93 octane as stated in the manual, so I add a $9 bottle of amsoil boost with every tank. 100 octane here in Los Angeles is $9.50 a gallon. I used to do 6 gal of 100 and top off my tank with 91 to reach 93 octane, but that got way too expensive.
That's what my 2018 GTR's gas cap labelled :93 Octane, trying to mix with 4.2 gal of 100 and 15.2 gal of 91 to make it 93 !!! nowadays 91 octane already $5.70per gallon...! Ding !
I've tried it in my Rs5 and noticed a difference immediately... I went off it again....noticed louder knocks and less smooth overall,,, back on it again with a stop watch... my times improved in 1/4 mile using octane boost...especially the mmt stuff
In my country, 95Ron costs $3.15/L , 98 Ron costs $3.75/L ..... on my BMW e92 , 63L fuel tank.... that works out to about $0.60 ×63 = $37.80 An STP OCTANE BOOSTER bottle, costs around $12 [ $10 if you buy in bulk ] .... 1 Bottle brings the tank of petrol up 2 octane ratings to 97 Ron , pretty close to 98 Ron but at savings of almost $25 a tank. Multiple $25 a tank x 4 tanks a mth , thats $100 in saving and $1200/ yr. Significant !
I'm at 5000+ elevation on Golf R APR Stage 2 with only 91 at the pump. For me adding a can of VP Ocatinium Unleaded (treats 10 gals and can raise by 7 numbers and is safe with O2 and cat) absolutely increases throttle response and acceleration. It took my car about half a tank of fuel to relearn/adjust the timing to the point where It was very obvious I was getting more power. By the second tank the power gains were maxed. I'll run this for now until I get my flex tune and then I wont need it anymore. I'm on my 5th tank of gas with it. The only problem is I don't really know how safe the additives are on the fuel system. I just recently upgraded my LPFP and shortly after this my gas tank roll-over valve appears to have stuck. Not sure why yet. Has anyone had any strange fuel system problems while running this stuff long term?
*How long did you continuously use VP Ocatinium? I heard it (and octane boosters in general) can cause issues with the O2 and cat. But I assume one bottle here and there won't do much.*
I run stp octane booster along with e3 spark plugs in my 1993 mistubishi 3000gt and it went from 22mpg to 35mph I havent driven my honda accord in 2 months cause the gt is running so well.
One benefit for octane booster is if you need pure gas, but the only pure gas you can find is that low 88 octane. It is so hard to find "premium" pure gas.
In Canada a full tank of 87% is $0.97 per liter. 94% cost $1.21. That is $0.24 per liter more. That is $21.00 per fill up more. You can buy a high end octane booster for $14.00
I clicked on this video to see if Octane Booster works in boosting octane. Most of us were already aware changing Octane doesn't produce more power in and of itself. We just wanted to know if it boosts the octane of 87 unleaded fuel, which wasn't addressed in a video about that very thing. 🙄
@@Dr-TH-cam Yes, but to what degree? For instance, if I was running a car that is tuned for 93 octane because it's running boost, how much octane booster would I need if only 87 is available and would it work?
Octane booster is to increase octane to decrease predetonation. It actually burns slower... It is ideal for high compression engines despite their horsepower output. That's why higher octane gas is recommended for even the 105hp turbo engines in the 80s. Not get more power but to prevent pinging and knocking. Apples to tomatoes... Now which octane boosters actually work?
Lucas works from what I’ve seen when I accidentally put in plus one day it raised the octane to a comfortable level. Normally premiums to the right this time it wasn’t but it would be handy to keep one lying around for that circumstance I guess. Once also tried 711’s brand of octane booster put some Lucas fuel-system cleaner with it to make sure my 02 sensor was alright. They are private labeling could be STP. $2 dirt cheap.
I have a Supercharged RAM and its tuned for either 91 or 93 Octane but where I live there is only 91 available. So if I were to use 93 or Octane booster would it actually work since its tuned for 93 but can only find 91? Thanks!
How much boost that supercharger make, and how much it changes the engine compression, using 93 on a 91-tuned engine would be a waste of money, and right now, almost every car has some sort of octane-sensing on it, just fill it up with anything and the ECU will adjust itself to the fuel
I just compared the price of octane boosters vs.changing to higher octane gas. It WAS, in fact, cheaper to buy the higher octane gas. (Than is in Riverside County, California.)
Does the ECU have enough adjustment to the timing to benefit the added fuel octane booster ? Does the ECU continue to advance the timing until the knock sensor detects knock or is there a limit ?
Some engines adjust ignition timing automatically. Ford Ecoboost engines are more likely to have gains in horsepower from higher octane. I have A prototype that allows for optimum ignition timing and my test car has A distributor for easy adjustment. Certain vehicles are better suited to my prototype than others.
2016 ford mustang ecoboost runs (about) 280- 285 hp on 87 octane (recommended), whereas running a 91 octane fuel runs roughly 310 hp. So yea your on the 💵 👍👍👍
I have a question, I drive a 2020 Toyota Tacoma TRD pro it is designed to run on 91 octane or higher. However when I go out into the more rural areas it is hard to find this kind of fuel they mostly sell 87 or 89 octane. If I was to add the octane booster to a lower octane fuel would that bring it up to the 91 octane needed for my truck would love to know the answer?
buying octane booster is worth it if you know how to use it and when to use it of at the time of gas sales are high or low , like right now gas is pretty high so gas booster is cheaper per tank of use i mean im saving like around 20dollars per tank of gas .
I don't have an Audi or VW, I have an older boat(1976), with V8 Chevy 307's that require 91 octane but the marina only sells 87 octane. Will octane help me?
If you have a car that recommends Super 92 octane and you only have available 87 octane, will an octane booster stop the car from knocking without damaging the engine?
The octane booster isn't going to add enough knock resistance to counterbalance the higher octane fuel... a bottle of octane boost doesn't make 87 octane 93
It depends on the volume of the fuel you're adding it to. If the octane booster has the same octane rating as say, Xylene, then 1 quart of it could be added to roughly (slightly less than) 4 quarts of 87 octane gas and it's blended value would become 93.
I've got a Toyota Tacoma with TRD supercharger which calls for premium fuel. Because I'm partial to non-ethanol fuel (which is readily available in my area as 87 octane) I add octane booster with every non-ethanol fill-up.
So have you had any problems with this approach? I also have a vehicle that says "Premium Fuel required" and hate paying the extra 10 dollars per fill up. ( My other car is diesel...so no worries about fuel there....and the mpg is incredible.)
Depends what one your buying . At my local race shop they have a mix that turns your 93 pump gas into 97 up to 117 octain . Comes in a 2 quart bottle , (actially does work) then you have your stuff at Canadian Tire or even dollar tree . No they don't . They might clean your injectors , carbon build up on spark plug or valves . But that's about it no added go
Boostane does. And yes increased octane on a performance car will yield positive results as long as it’s not more than 3 numbers above what it is tuned for.
Octane is not power, is the ability to resist detonation. Meaning advancing the timing is possible, however if the ecu is not tuned to advance it, it wont, and therefore power lose will occur instead because octane booster has less energy than regular gas.
Perfect Stranger it depends. Some are bunk, some work. My bike sucked with all the products out there except the "not street legal" NOS product using MMS
I got a VW GLI 2.0TSI that is supposed to run on 93 octane fuel. We got Mobil and Shell recently in Mexico and are, suposedly, better fuels than the one from Pemex (mexican oil company). I've noticed Shell's V-Power gives a little bit more power to my engine and makes it more responsive but I just discovered it is 91 octane rated compared to 93 octane of Pemex's fuel. Would it be a good idea to run my GLI on Shell's V-Power and use an octane booster to prevent damage to my engine?
Luis Angel Ibarias Ruiz i hate to say it because I’m not shilling for shell but I go there bro and I believe the studies it’s better fuel look for some cheap octane booster if you notice knock brother good luck with it
Please help my infotainment screen, shows a silver like steering wheel when ever I go to vehicle status, The car hasn't reported any faults yet but this cannot be a good thing. My car is a Mk7 GTI 2015 model
Stick to the question...no one cares about octane and horsepower relationship...this is about whether these boosters do indeed raise the octane level so we can use these boosters with regular gas for our cars that require 91-93 octane fuel.
I ran too much octane booster and my plugs all turned orange! I'm assuming the bottom of all my valves are orange and so is the top of my pistons? Now that all is orange can I burn this shit off using premium unleaded gas here in CA and just quit using the booster? Or did I harm the motor??
Here’s the simple answer no need for this blokes bla bla bla .....The reason why u could get a slight power gain from the octane booster additive is that it allows the ecu to (slightly) and I mean slightly advance the ignition timing due to the raised octane when the knock sensor detects knock/ping at a lower octane it retards timing thus reducing power so in simple terms yes it works
Ok, for our older VW's that don't like ethanol in the gasoline, would it be a good idea to buy ethanol free gasoline (It is usually only available in 89 octane) and add an octane booster to bring the gas to 93 octane???
Hi I have one question to help me a lot I you can plz tell me thx. I have a fiat punto gt with 2560r if I put boost octane can add a little bit of psi to my engine for example 1.1 to 1.2bar
I have a question so my 08 5.3 is fully bolt on with cam and 3200 stall rebuilt transmission 4l60e 430 gears Nd is tuned for 93 octane but where I’m working at now there’s only 91 and there’s octane boosters for sale at Walmart that claim boosting by 3 so that puts me at 94 now would I have to use that every time I fill up or every other time
If you really need 93 I'd put it in every time. But if you are n/a aaand not constantly hot rodding it..91 will be just fine no worries.. i had a built 5.3 that was tuned for 93 as well and 91 never bothered it unless i was pretending i was speed racer
I got a buddy that thinks spark plugs and air filters give his car more horsepower even though it has not been tuned to run them make a video explaining this so I can show him I’m not the only one
Our VW mk2 1.8 8V motors require 92 octanes. I chipped my ECU and now have better running more powerful running Jetta. Years ago we would take our snowmobiles to Lincoln Montana for the drag races. We would always go to the airport and fill up with aviation fuel we got a lot more power and our sleds ran cooler. High Octane allows oars that require this fule to make the power they were designed to put out. Are you saying it does little for your average 87 obtain vehicles other than they run cooler which helps the vehicle to make a little extra power? If my car would run on 87 CORN JUICE I would run it, especially now that 92 is through the roofs (Priced) but it's Ethanol Free. Montana has a law that all gasoline (low test) which is a term from the 60s. Filler up with High Test. and our dates would think "Aint he neet". And the attendant would pop your hood and check your fluids, hell they didn't even ask. We still have one Full-Service Station in Town "For the Older Ladies" who no longer have a man in the house. Oh the fuel on that one island is full service and you pay dearly for it, but you get your windows cleaned and your tires checked and all the fluids topped off for an extra fee depending on how many pints you needed. Great Content Men keep up the Great Work. Love your MK1.
Actually he did answer the question and he said yes it does boost all came but he says he doesn't believe that it is cost efficient I don't know how you couldn't figure that out from the video
Yup, should be good. Most cars ECU will be able to detect the octane of the fuel (through knock sensors) and will adjust timing accordingly. Unless your car is detonating/pinging, you shouldn't have any damage. However, you may see more power and throttle response with using 93 octane that your car has been tuned for.
@@Geoffvader I have a Bama tunes for life membership and now with Palm Beach Dyno and a rule of them is if you are running a 93 race or street tune you don't go below 93 to 91 and any tuning company will tell you this! These guys should be contacting their tuners and have a revision made for 91 octane street or race tune but don't go and tell these guys it's safe to go lower than what you're suppose to be running! It's ONLY OK to go be on a 91 tune and use Ultra 94...
Oh this is an easy one, i got this, It just means the car can adjust to 87, 89, or 91 or higher. The car's ECU will be able to detect the octane of the fuel (through knock sensors) and will adjust timing accordingly. :D hope that helps! I would recommend only using 91 only if you have a turbo charged car otherwise your wasting money and hurting fuel economy. Mainly, just do what your car says. 87 if times are tough or 91 if you got the dough for max turbo power!
so, for instance, if you live in an area with questionable fuel quality, but run a GDI engine which requires high octane fuel, octane boosters are a must have?
I moved out to AZ in 2012 and couldn't believe they didn't even have 93 octane in the entire state. I had to go into the Chevron and the guy told me this. I drive a Honda S2000 and have never put in anything lower than 93 in my car. I eventually moved back to GA and the only good thing was the 93 octane.
Alpha Fort, In an engine that has good power and has VVT of some sort, actually benefit from higher octane fuels because the ECU actually changes timing all the time while driving..the reason people advanced timing in old cars was to increase power when racing. If it didn't work, they wouldn't have done it. So all the people thinking you don't need higher octane fuel to compensate for advanced timing have no clue how it works. I've read lots of places stating the 87 octane fuel causes damage over time but don't remember as to why, but the ECU in modern technology actually adapts to different octanes..it just takes A couple of tanks of each before it works.. Running high test gas every day for normal driving would be A waste but if you need the power, you would have it. I run 89 octane. It's A happy medium. NOS with MMT works the best for octane booster. I have also used 91% rubbing alcohol as it is the same as Iso Heet in the red or yellow bottles, and is cheaper. It does make A difference...I can tell it in my car. Starts faster, idles smoother, responds to the pedal better, and it does NOT tick. I'll never believe any negative comments about the subject because I've done it firsthand
@@MemphisMojo15s I realize this is an old thread, but if you're still out there... If your car's manufacturer recommends premium, how feasible is it that it would just adjust to a lower octane and sustain no damages or ill effects? Not asking about power/racing, but about safety and vehicle longevity.
@@MemphisMojo15s The question was "do these boosters' increase octane level"? We don't care about Horsepower and other junks, we want to know if we can use regular gas for our car that requires premium. Can these boosters be used to use regular gas instead of premium....no talks about if they make your car more powerful and stuff.
@@WaywardAnalysis same. My car requires 93 (from factory-premium fuel only) and I just moved to an area where I can only get 87. Do octane boosters work?
What im trying to figure out is my car requires 93 octane but we can only get 91 here so if i add a booster will it make any difference in performance?

Octane booster can it bring 87 all the way up to 91?? . If your car really needs 91 octane and you are actually getting 87 ( even if you hit the 91 button at the pump ) by the time you have got a few miles down the road and hit the gas pedal hard. You hear "that knocking" your left wondering did I actually get what I paid for . I would rather buy 87 octane add some booster ( that works) rather than pay for 91 and just crossing my fingers. Even if it is a little more expensive
91 is 75 c more than 87. 17 gallon tank make it $13. Dyno tab increase 1 level for 5 gallon and that 1$ per tablet. So that you need approximately 12 tablet ( not accurate, the more you put the less level it can increase, it is only rough calculation) which cost $12. Don’t quite worth the money to use 87+ additives instead of 91. You are NOT saving money.
This guy took a really simple question and turned it into a monstrosity of an answer. The answer is yes it does boost your power I have a 2002 Buick regal LS put it in after 2 weeks started noticing a power difference it never had before it will sit there and spend the wheels now just from adding octane boost STP octane boost is what I recommend.
Almost all octane boosters use MMT, which can clog the catalytic converter over time. A cleaner way is to use a gallon or two of E85 per tank. And it’s cheap. This is only for cars newer than about 2010 because older fuel line materials might be damaged. Like all octane boosters it doesn’t increase power unless you advance the timing or raise the compression ratio. But it does fix detonation problems and makes the engine run a little cooler.
you would need octane booster if you are supposed to run on 100+ Octane fuel due to tuning or manufacturer requirement and you drive to a country which does not easily provide this high grade fuel.
I have a focus st that banifits from 93octain, will adding octain booster to 87oct will it be Like having 93 in it? I'm trying to save money at the pump. 93 is about 3.50 a gallon and 87 is around 2.89.
No, octane booster isn't able to increase like that.. say a bottle off ob treats 15 gallons.. so you have 15 gallons of 87 octane in your car and you add ob. It will only be 89 octane at most and that's being generous.. most often the big benefit of ob.. is say your car is tuned at 93 octane.. you need gas but only 91 is available.. you can add an ob to bring it closer to 93
All this fancy talk ain’t cutting it, I have a Jeep n big tires n so on it’s heavy I totally depend on high octane fuel 93 or better, it helps a lot no fancy talk just necessity n experience it works n every now n again I use 104 octane boost it makes a world ov difference, sorry ur wrong, just cause ur on you tube, doesn’t make you n expert so many ov yous on here...
I put 108 Booster in my FI Triumph speed triple motorcycle and I can tell you the throttle response is much better with booster than straight 92 Octane. BTW my engine has 12:1 compression.
Octane boosters aren't used to boost hp, I repeat, octane boosters don't boost hp - octane boosters are used in Higher Compression Ratio engines so these engines will run properly without preignition (detonation) and 'deiseling' in carbureted engines when you turn them off - it's the higher compression that leads to the 'higher horsepower' iykwim. That's not disputable. However, if your car has a 'compression ratio' of 10 to 1 or higher and you are running premium gas of an octane rating (AKI) in the US of 91 BUT that 91 Octane rating has been achieved by adding 10% Ethanol (octane of 100) as almost all fuels in the US now have 10% Ethanol, then things get more interesting. Gallon per gallon, ethanol has about 2/3 the energy content of gasoline so, although the octane of your gas is now 91 your car will not do as much 'work' with the 'gallon' of an ethanol blended gasoline to the 'gallon' of similar octane gasoline without ethanol - in other words, it'll be less efficient (get worse gas mileage). When you boost your octane sensibly your engine, with it's fuel metering and ignition timing software, will adjust accordingly to the improved 'real' octane it is 'seeing' primarily by sensing less preignition, most of which you cannot hear, and some you might ( 'knocking' ) to improve things like 'drivability' for lack of better way to describe it . Modern, performance street cars can benefit from boosting octane to an (AKI) of 94 to 96 - higher compression, performance engines with or without superchargers from the '50's, 60's and '70's do benefit from Octane levels up to about 102 to 104 (or was that RON back then? either way that would be 97 to 99 in today's numbers) - remember when it was labeled 102 above the premium gas pumps ? - boy am I old ; P .
Well put.
I'm getting old too
But not 102!!
Spot on.
Not even a Mazda 3 with the new Sky-Activ X 2.0L engine and a compression ratio of 16.3:1 recommends more than 95 RON fuel.
Higher octane gas can increase power in modern turbocharged engines like the ecoboost. The ecu is tuned to detect knock and will advance and retard timing to the fuel used to a degree. It's pretty significant. Obviously the octane does not increase power but it allows the car to modify its tune more aggressively without damaging the engine.
You should do this video again with the fuel costs from 2022. Where I live, Premium (91 octane PON) is USD$0.50 per gallon more than Regular (87 octane PON). Rislone 4747 costs $2.50 for a 6 oz bottle and claims to increase 20 gallons by 20 points (2 octane levels).
Doing the math, 20 gallons of Regular is $3.33 currently, so $66.60 total. Add 2 bottles of octane booster to bring the 87 to a 91, and I'm at $71.60.
20 Gallons of Premium is $3.83 currently so $76.60.
In this case, Octane Booster seems to save me $5 or about 6.5%.
I think in 2016 the price difference between Regular and Premium was different, like USD$0.20 to USD$0.30 per gallon. Times change, eh?
my sentiments exactly, with gas now going $5 plus. And now in Michigan, there's a 75 cent difference per gallon from 87 to 93. I have a Wrangler 2.0 which puts out more power with premium, and a Mustang GT tuned for 92 octane, so I have 2 different examples where I'd like to know if going to a bottle solution would be sufficient and have the same effect as buying 93 octane gas.
@@robsolf I've learned a bit more with information from the octane booster manufacturers.
If they state "20 points" as Rislone 4747 does, that's 2 octane. However, doubling the additive does not yield another 2 octane, and can cause problems in the fuel with MMT fouling.
I do think that modern engines in cars is different than my use in a 2-stroke engine, so octane booster in cars that need premium to run correctly is a viable option, as long as the octane booster can increase your octane enough as stated on the bottle, e.g. 89 to 91 for an octane booster that claims 20 points.
In turbo charged cars especially when it's boosted over the factory limit it's almost a necessity and it does actually give you noticeable horsepower gains in turbocharged cars regular cars not so much
Higher octane is needed when either compression is high, timing is advanced, running boost etc. The higher the octane, the more aggressive tune can be ran to make more power. These scenarios create a condition where detonation can occurs and detonation destroys motors.
Yeah, I'm considering doing 10 to 1 forged pistons in mine ( A modified Saturn SL2) , with low boost, 8-10 PSI, just to get the added torque when just cruising normally around town and not having to rely as much for power all the time with boost. .I'm having the combustion chambers polished with the port and polished head job and I run premium in the car and have been for years. I suppose if I really wanted peace of mind I could always run E85 with the build and tune, etc.
Sometimes I get octane booster instead of premium or ultra because where I live 93 gas can cost about 70-80 cents more per gallon than 87 and then I can get the octane booster for around $2 - $3... but there are other areas where the better octanes prices aren't significantly more expensive than the lower octanes.
And you actually think you’re getting a similar end product? Funny the gas companies haven’t noticed
Octane is a retardant that inhibits combustion for better ignition control in high compression engines. It is used to prevent pre-ignition or detonation when combustion changer temperatures and pressure become elevated. The term "Booster" is miss leading as it does "boost" your octane level, but octane does not provide "boost" like a supercharger or turbo.
Yes! The only reason I run octane booster in my '86 Scirocco is because we did an engine swap that gave it a much high compression therefore I need more octane to counter the retardant of the engine and have it run a little smoother.
finally someone who knows!!!!
Is this different for cars with direct injection such as bmw 335i?
@@david-tracy No, you're still compressing a fuel air mixture. If you want to fit more in there it has to be compressed more and ignited earlier. You still need a fuel that resists detonation so you can accurately control the ignition timing.
Again, we don't care if octane does nothing for the car....just if we can use regular gas instead of premium gas with these boosters...because we have cars that says "premium fuel required"
I tried it on dyno... High octane allows you to advance spark and pump more fuel into chamber without detonation... If you know what you are doing you get more hp by octane... If you know what you are doing... I gained 8 whp by adding octane
I'm a qualified mechanic. Simply, high compression motors have to sacrifice ignition advance to counter pinging and detonation.
Ignition advance often (but not always) makes power as does high compression but the fuel available often isn't compatible for both advance and high compression in modified motors.
An octane booster can allow more advance on high compression motors that are modified by the USER (rather than by a highly tuned factory engine that has all that sorted by the manufacturer).
It is always important to follow the manufacturers' fuel recommendations because putting low octane 91 fuel in motors designed for 98 induces what octane boosters are trying to stop.
Now OEM fuel injected performance motors,
It is unlikely that an octane booster is going to result in more power because the engine management computer isn't going to advance the ignition timing beyond the factory pre set ignition advance. That said it is possible to improve on factory setting by modding the computer and an octane booster may allow more power but the downside is you're stuck using an octane booster at every fill up.
What some people do is tune for 98 octane pump gas when a motor was specified for lower octane fuel.
Must remember the power isn't coming from the fuel or the fuel additive.
On another matter, aviation fuel (Avgas) is high octane for different reasons than high compression. It is designed to resist detonation with varying power settings at varying air densities. Aviation engines are low compression but have to be able to be substantially leaned. This leaning induces detonation, as does combinations of high load, low rpm high ambient air temperature and rich mixtures. That fuel is designed for that application but can be used in automotive applications although racing fuel is better.
Avgas has old school lead in it - so it can't be used with any motor that has a catalytic convertor.
I had an old 4 cylinder car with no cat, that I used up the remains of several drums of Avgas in and it made absolutely no difference to it. The exhaust however went a nice mid-light grey showing me it was running well lol.
Turbos and higher compression motors can benefit from higher octane fuel. Our 2024 Mazda CX 5 has a naturally aspirated engine with a compression ratio of 14:1. That is higher than any naturally aspirated engine of this type. I definitely noticed a peppier response when I used 93 octane fuel, especially from 0-50. The gas mileage was slightly better overall, roughly an increase of 1-2 mpg combined.
If your vehicle calls for 87 octane or higher as exhibited in your manual, you may receive a performance and/or an increased mileage benefit from 93 octane gas.
It’s worth a try.
I have a 1971 Scamp 360 375HP. I occasionally put STP octane booster plus in her tank during fill ups. I will tell you, when I do ~ Boom! She gets up and goes, chirping wheels at every gear. Don’t know the science behind it, but I know she likes it. Moonshine for the car!
Great explanation. My car requires a higher octane fuel than what is available in my country. Is it safe to use stp octane boost which contains MMT? Would it cause harm to engine components?
It’s safe to use.
So here's my question. My 2013 v6 mustang is set up with high performance. I have a tuner. 87 89 91 and above octane setting. I usually go for 93 octane with 10 percent ethanol. What if I use 87 non ethanol and put octane booster in it and still set tuner to 91 and above?Why do I do this you ask? Long term fuel storage. Don't get into the long term storage questions. Just the non ethanol with booster and tune setting questions. Thank you for whatever input you have because I realize you would have to have a level of genius beyond me
My 2013 Hyundai Accent knocks with either 87, 91 and a bit less with 93. So I decided to add Sunoco 100 to the 93 octane and it is awesome!!!! Not only I got to eliminate the knock but I have seen milage gain for daily highway and city daily driving. I did not knew that my car came with about 210psi compression and a local machine shop had many of these engines destroyed at 40k mules due to use of poor fuel and owners not hearing the knocking. so that is my take over high octane fuel vs. octane booster. as someone said before, a bottle does not take 87 to 93...
My car requires 93 octane as stated in the manual, so I add a $9 bottle of amsoil boost with every tank. 100 octane here in Los Angeles is $9.50 a gallon. I used to do 6 gal of 100 and top off my tank with 91 to reach 93 octane, but that got way too expensive.
That's what my 2018 GTR's gas cap labelled :93 Octane, trying to mix with 4.2 gal of 100 and 15.2 gal of 91 to make it 93 !!! nowadays 91 octane already $5.70per gallon...! Ding !
I've tried it in my Rs5 and noticed a difference immediately... I went off it again....noticed louder knocks and less smooth overall,,, back on it again with a stop watch... my times improved in 1/4 mile using octane boost...especially the mmt stuff
Any idea y the louder knocks anyone?
In my country, 95Ron costs $3.15/L , 98 Ron costs $3.75/L ..... on my BMW e92 , 63L fuel tank.... that works out to about $0.60 ×63 = $37.80
An STP OCTANE BOOSTER bottle, costs around $12 [ $10 if you buy in bulk ] .... 1 Bottle brings the tank of petrol up 2 octane ratings to 97 Ron , pretty close to 98 Ron but at savings of almost $25 a tank.
Multiple $25 a tank x 4 tanks a mth , thats $100 in saving and $1200/ yr.
Significant !
I'm at 5000+ elevation on Golf R APR Stage 2 with only 91 at the pump. For me adding a can of VP Ocatinium Unleaded (treats 10 gals and can raise by 7 numbers and is safe with O2 and cat) absolutely increases throttle response and acceleration. It took my car about half a tank of fuel to relearn/adjust the timing to the point where It was very obvious I was getting more power. By the second tank the power gains were maxed. I'll run this for now until I get my flex tune and then I wont need it anymore. I'm on my 5th tank of gas with it. The only problem is I don't really know how safe the additives are on the fuel system. I just recently upgraded my LPFP and shortly after this my gas tank roll-over valve appears to have stuck. Not sure why yet. Has anyone had any strange fuel system problems while running this stuff long term?
*How long did you continuously use VP Ocatinium? I heard it (and octane boosters in general) can cause issues with the O2 and cat. But I assume one bottle here and there won't do much.*
I run stp octane booster along with e3 spark plugs in my 1993 mistubishi 3000gt and it went from 22mpg to 35mph I havent driven my honda accord in 2 months cause the gt is running so well.
22mph to 35mpg not mph sorry autocorrector.
One benefit for octane booster is if you need pure gas, but the only pure gas you can find is that low 88 octane. It is so hard to find "premium" pure gas.
Yeah it won’t “give” you more power, but it will help keep your ecu from “pull”ing it away from you (i.e. pulling timing)
In Canada a full tank of 87% is $0.97 per liter. 94% cost $1.21. That is $0.24 per liter more. That is $21.00 per fill up more. You can buy a high end octane booster for $14.00
I clicked on this video to see if Octane Booster works in boosting octane. Most of us were already aware changing Octane doesn't produce more power in and of itself. We just wanted to know if it boosts the octane of 87 unleaded fuel, which wasn't addressed in a video about that very thing. 🙄
Think you're the only one that needs to be told if octane booster boosts octane...lol
@@Dr-TH-cam Yes, but to what degree? For instance, if I was running a car that is tuned for 93 octane because it's running boost, how much octane booster would I need if only 87 is available and would it work?
Octane booster is to increase octane to decrease predetonation. It actually burns slower... It is ideal for high compression engines despite their horsepower output. That's why higher octane gas is recommended for even the 105hp turbo engines in the 80s. Not get more power but to prevent pinging and knocking. Apples to tomatoes... Now which octane boosters actually work?
Lucas works from what I’ve seen when I accidentally put in plus one day it raised the octane to a comfortable level. Normally premiums to the right this time it wasn’t but it would be handy to keep one lying around for that circumstance I guess. Once also tried 711’s brand of octane booster put some Lucas fuel-system cleaner with it to make sure my 02 sensor was alright. They are private labeling could be STP. $2 dirt cheap.
Here in Germany you get 102 octane at your normal gas station. 😎
How much does that cost per gallon??
@@vansboy755 its different its true 102 octane in Europe is equal to 95 oct in USA.
@@shanekirby8625 where is 87oct top fuel?
Wish we had here in south africa 🇿🇦 😪
True but in Europe the elevation is much lower then USA so we don’t require higher octane
I have a Supercharged RAM and its tuned for either 91 or 93 Octane but where I live there is only 91 available. So if I were to use 93 or Octane booster would it actually work since its tuned for 93 but can only find 91? Thanks!
Joel Robles I’m tune on 93 and only have 91 octane available. I use 2 gals of e85 and fill with 91. What did you end up using?
How much boost that supercharger make, and how much it changes the engine compression, using 93 on a 91-tuned engine would be a waste of money, and right now, almost every car has some sort of octane-sensing on it, just fill it up with anything and the ECU will adjust itself to the fuel
Am sorry bud, wish I knew the answer for you I'm seeking the same
Ppl just seem to wanna talk instead of answering what was asked.
I just compared the price of octane boosters vs.changing to higher octane gas. It WAS, in fact, cheaper to buy the higher octane gas. (Than is in Riverside County, California.)
not any more
Does the ECU have enough adjustment to the timing to benefit the added fuel octane booster ? Does the ECU continue to advance the timing until the knock sensor detects knock or is there a limit ?
Some engines adjust ignition timing automatically. Ford Ecoboost engines are more likely to have gains in horsepower from higher octane.
I have A prototype that allows for optimum ignition timing and my test car has A distributor for easy adjustment. Certain vehicles are better suited to my prototype than others.
2016 ford mustang ecoboost runs (about) 280- 285 hp on 87 octane (recommended), whereas running a 91 octane fuel runs roughly 310 hp. So yea your on the 💵 👍👍👍
I have a question, I drive a 2020 Toyota Tacoma TRD pro it is designed to run on 91 octane or higher. However when I go out into the more rural areas it is hard to find this kind of fuel they mostly sell 87 or 89 octane. If I was to add the octane booster to a lower octane fuel would that bring it up to the 91 octane needed for my truck would love to know the answer?
I have a 2018 Silverado with a 5.3 direct-injection 11 to 1 compression I gained 25 horsepower to the wheels and that is amazing...
Just by adding a octane booster on 93 pump gas...
Did you put the octane booster in first?
buying octane booster is worth it if you know how to use it and when to use it of at the time of gas sales are high or low , like right now gas is pretty high so gas booster is cheaper per tank of use i mean im saving like around 20dollars per tank of gas .
I don't have an Audi or VW, I have an older boat(1976), with V8 Chevy 307's that require 91 octane but the marina only sells 87 octane. Will octane help me?
If you have a car that recommends Super 92 octane and you only have available 87 octane, will an octane booster stop the car from knocking without damaging the engine?
Price spread between premium and regular grades of gasoline now $.60 per gallon.
So higher octane prevents the engine knocking? Or does it cause it?
In January 2019, for 20 gallons of gasoline, it costs $10 more to get super or $3 for octane booster.
The octane booster isn't going to add enough knock resistance to counterbalance the higher octane fuel... a bottle of octane boost doesn't make 87 octane 93
It depends on the volume of the fuel you're adding it to. If the octane booster has the same octane rating as say, Xylene, then 1 quart of it could be added to roughly (slightly less than) 4 quarts of 87 octane gas and it's blended value would become 93.
@@bitTorrenter I'd be scared to put that to the test in some cars. Lol
I've got a Toyota Tacoma with TRD supercharger which calls for premium fuel. Because I'm partial to non-ethanol fuel (which is readily available in my area as 87 octane) I add octane booster with every non-ethanol fill-up.
Thomas Wieser : Double Check that Oct.Rating,Most Non Ethanol REG.Fuels Give U A Higher Oct.Rating .One that Shell Sells is 90 octane
So have you had any problems with this approach? I also have a vehicle that says "Premium Fuel required" and hate paying the extra 10 dollars per fill up. ( My other car is diesel...so no worries about fuel there....and the mpg is incredible.)
but do the additives actually increase your octane level?!?!?!?!?
Depends what one your buying . At my local race shop they have a mix that turns your 93 pump gas into 97 up to 117 octain . Comes in a 2 quart bottle , (actially does work) then you have your stuff at Canadian Tire or even dollar tree . No they don't . They might clean your injectors , carbon build up on spark plug or valves . But that's about it no added go
Yess
@@204_mod_shop
Do they also quiet the engine?
Boostane does. And yes increased octane on a performance car will yield positive results as long as it’s not more than 3 numbers above what it is tuned for.
Octane is not power, is the ability to resist detonation. Meaning advancing the timing is possible, however if the ecu is not tuned to advance it, it wont, and therefore power lose will occur instead because octane booster has less energy than regular gas.
my car knocks due to bad quality petrol available in my country. Will octane buster help to aliminate or reduce knocking?
Perfect Stranger it depends. Some are bunk, some work. My bike sucked with all the products out there except the "not street legal" NOS product using MMS
depends on the compression ratio on your car
Is this still true if it's direct injection such as a bmw 335?
I got a VW GLI 2.0TSI that is supposed to run on 93 octane fuel. We got Mobil and Shell recently in Mexico and are, suposedly, better fuels than the one from Pemex (mexican oil company). I've noticed Shell's V-Power gives a little bit more power to my engine and makes it more responsive but I just discovered it is 91 octane rated compared to 93 octane of Pemex's fuel. Would it be a good idea to run my GLI on Shell's V-Power and use an octane booster to prevent damage to my engine?
Luis Angel Ibarias Ruiz i hate to say it because I’m not shilling for shell but I go there bro and I believe the studies it’s better fuel look for some cheap octane booster if you notice knock brother good luck with it
Please help my infotainment screen, shows a silver like steering wheel when ever I go to vehicle status, The car hasn't reported any faults yet but this cannot be a good thing. My car is a Mk7 GTI 2015 model
Running a higher octane than needed will reduce horse power! Higher octane slows the flame propagation.
Stick to the question...no one cares about octane and horsepower relationship...this is about whether these boosters do indeed raise the octane level so we can use these boosters with regular gas for our cars that require 91-93 octane fuel.
I ran too much octane booster and my plugs all turned orange! I'm assuming the bottom of all my valves are orange and so is the top of my pistons? Now that all is orange can I burn this shit off using premium unleaded gas here in CA and just quit using the booster? Or did I harm the motor??
I think you are in trouble...
Octane booster real just helps with the car shifting slightly more smoothly.
Here’s the simple answer no need for this blokes bla bla bla .....The reason why u could get a slight power gain from the octane booster additive is that it allows the ecu to (slightly) and I mean slightly advance the ignition timing due to the raised octane when the knock sensor detects knock/ping at a lower octane it retards timing thus reducing power so in simple terms yes it works
Yes, it would cost dramatically more to make 87 a 93 with boosters.
If the label says raises octane seven points, that’s .7 of one octane increase.
Ok, for our older VW's that don't like ethanol in the gasoline, would it be a good idea to buy ethanol free gasoline (It is usually only available in 89 octane) and add an octane booster to bring the gas to 93 octane???
I'm referring to MK1, 2, and possibly 3.
Hi I have one question to help me a lot I you can plz tell me thx. I have a fiat punto gt with 2560r if I put boost octane can add a little bit of psi to my engine for example 1.1 to 1.2bar

Our VW mk2 1.8 8V motors require 92 octanes. I chipped my ECU and now have better running more powerful running Jetta. Years ago we would take our snowmobiles to Lincoln Montana for the drag races. We would always go to the airport and fill up with aviation fuel we got a lot more power and our sleds ran cooler. High Octane allows oars that require this fule to make the power they were designed to put out.

My car is tuned for 93 octane and all I have in my state is 91 octane. Am I fine to drive with the minus 2 octane? Or should I add octane booster?
I had the same exact question
Yup, should be good. Most cars ECU will be able to detect the octane of the fuel (through knock sensors) and will adjust timing accordingly. Unless your car is detonating/pinging, you shouldn't have any damage. However, you may see more power and throttle response with using 93 octane that your car has been tuned for.
@@Geoffvader I have a Bama tunes for life membership and now with Palm Beach Dyno and a rule of them is if you are running a 93 race or street tune you don't go below 93 to 91 and any tuning company will tell you this! These guys should be contacting their tuners and have a revision made for 91 octane street or race tune but don't go and tell these guys it's safe to go lower than what you're suppose to be running! It's ONLY OK to go be on a 91 tune and use Ultra 94...
You need to add octane booster .
What does it mean “87 octane or higher is recommended?
Oh this is an easy one, i got this, It just means the car can adjust to 87, 89, or 91 or higher. The car's ECU will be able to detect the octane of the fuel (through knock sensors) and will adjust timing accordingly. :D hope that helps! I would recommend only using 91 only if you have a turbo charged car otherwise your wasting money and hurting fuel economy. Mainly, just do what your car says. 87 if times are tough or 91 if you got the dough for max turbo power!
so, for instance, if you live in an area with questionable fuel quality, but run a GDI engine which requires high octane fuel, octane boosters are a must have?
I moved out to AZ in 2012 and couldn't believe they didn't even have 93 octane in the entire state. I had to go into the Chevron and the guy told me this.

I use vp’s octane booster in my Miata because it’s running 17PSI and 91 octane doesn’t quite cut it😂
the question was " does it work" = i.e., does it raise the octane rating of the fuel> well does it?
Alpha Fort, In an engine that has good power and has VVT of some sort, actually benefit from higher octane fuels because the ECU actually changes timing all the time while driving..the reason people advanced timing in old cars was to increase power when racing. If it didn't work, they wouldn't have done it. So all the people thinking you don't need higher octane fuel to compensate for advanced timing have no clue how it works. I've read lots of places stating the 87 octane fuel causes damage over time but don't remember as to why, but the ECU in modern technology actually adapts to different octanes..it just takes A couple of tanks of each before it works.. Running high test gas every day for normal driving would be A waste but if you need the power, you would have it. I run 89 octane. It's A happy medium. NOS with MMT works the best for octane booster. I have also used 91% rubbing alcohol as it is the same as Iso Heet in the red or yellow bottles, and is cheaper. It does make A difference...I can tell it in my car. Starts faster, idles smoother, responds to the pedal better, and it does NOT tick. I'll never believe any negative comments about the subject because I've done it firsthand
@@MemphisMojo15s I realize this is an old thread, but if you're still out there...

If your car really needs 91 octane and you are actually getting 87 ( even if you hit the 91 button at the pump ) by the time you have got a few miles down the road and hit the gas pedal hard. You hear "that knocking" your left wondering did I actually get what I paid for . I would rather buy 87 octane add some booster ( that works) rather than pay for 91 and just crossing my fingers. Even if it is a little more expensive
Would octane booster help with preignition when using nitrous? Asking for a friend lol
That’s too much
Car is tune to 98 for max performance but in my country only 91 this is good for me ?
Yes
great video, thank u for making it simple
91 is 75 c more than 87. 17 gallon tank make it $13. Dyno tab increase 1 level for 5 gallon and that 1$ per tablet. So that you need approximately 12 tablet ( not accurate, the more you put the less level it can increase, it is only rough calculation) which cost $12. Don’t quite worth the money to use 87+ additives instead of 91. You are NOT saving money.
This guy took a really simple question and turned it into a monstrosity of an answer. The answer is yes it does boost your power I have a 2002 Buick regal LS put it in after 2 weeks started noticing a power difference it never had before it will sit there and spend the wheels now just from adding octane boost STP octane boost is what I recommend.
What if your running on 93 octane and you add turbo 108 octane booster ??
Then you might have 93.5 octane
No tune, no gain
Almost all octane boosters use MMT, which can clog the catalytic converter over time. A cleaner way is to use a gallon or two of E85 per tank. And it’s cheap. This is only for cars newer than about 2010 because older fuel line materials might be damaged. Like all octane boosters it doesn’t increase power unless you advance the timing or raise the compression ratio. But it does fix detonation problems and makes the engine run a little cooler.
3:09 Is it worth it to use octane booster nowadays?
you would need octane booster if you are supposed to run on 100+ Octane fuel due to tuning or manufacturer requirement and you drive to a country which does not easily provide this high grade fuel.
Great honest vid... Octane booster is junk
Little did he know , fuel would be almost 4$ in the future and octane booster is still 5$ a bottle makes my gas las longer
I have a focus st that banifits from 93octain, will adding octain booster to 87oct will it be Like having 93 in it? I'm trying to save money at the pump. 93 is about 3.50 a gallon and 87 is around 2.89.
Mark Simrow how is this working interesting I’m on same boat
No, octane booster isn't able to increase like that.. say a bottle off ob treats 15 gallons.. so you have 15 gallons of 87 octane in your car and you add ob. It will only be 89 octane at most and that's being generous.. most often the big benefit of ob.. is say your car is tuned at 93 octane.. you need gas but only 91 is available.. you can add an ob to bring it closer to 93
I agree
Regular unleded in the uk is 95 how come the us only gets 87
Different rating system 95 = 87
Europe uses RON and the u.s. uses PON. 95ron is 87pon 100ron is 91pon etc.... why we always have to be different is beyond me
Octane actually lowers a fuels power density, contrary to popular belief
What are you talking about??? In my car with 95 octane i have 450hp and 600 NM, with ARAL ULTIMATE 102 OCTANE + BOOSTANE i have 55hp and 60 Nm MORE
You already almost looked like tony stark.
Insert adaptive octane logic
Here in 2022 when 93 is 6 dollar's a gallon
All this fancy talk ain’t cutting it, I have a Jeep n big tires n so on it’s heavy I totally depend on high octane fuel 93 or better, it helps a lot no fancy talk just necessity n experience it works n every now n again I use 104 octane boost it makes a world ov difference, sorry ur wrong, just cause ur on you tube, doesn’t make you n expert so many ov yous on here...
I put 108 Booster in my FI Triumph speed triple motorcycle and I can tell you the throttle response is much better with booster than straight 92 Octane. BTW my engine has 12:1 compression.
exactly what product? i have a street triple and the quality of gas in my country is shit.
I use ethanol free fuel. My Nissan seems to run better.
YES OR NO!!!
Octane boosters do not work. Race gas or octane concentrates do, like Boostane, Torco, or octanium.
Pour over paint
Hottest platinum lugs and wires add more power
otherwise the the best quality fuel I can get is 91
91 Ron? Whoa we get 95 Ron
Dude we don’t Wana lesson on how fuel works… just answer the question!!!
