Oh this is joy! A Russian product too, being imported to the west: how the tables have turned since the Soviet days. Whatever that sample is of measured 93 AKI, I'll speculate that it might be 99 RON, 87 MON, thus 93 AKI.
In Russia, petrol tests you! Yes, it certainly doesn't seem any better quality than Soviet products! 😆 93 is more like 97.5 RON 85.5 MON, but this tester does decimal places, so I might have to round up as it was surprisingly lower than I expected. 99 RON is 94.5 AKI according to a few charts I downloaded and I still have to experiment with the tester to see if setting it to RON requires recalibration.
In general yes, but apparently there are variables on how MON is measured or that it's a minimum at all conditions whereas RON is not (from some quick reading that I didn't fully understand) so it makes conversion formulas a little imprecise. A general one I was given to simplify is RON=AKI*(22/21) so I don't have to pay much attention to MON, hence my inaccurate guesses the from memory above. Looking at the tables, 93 AKI shows as 97.4 RON and 89 MON, which works out as the pair averaged. Using the formula it works out the same.
I can't. My tester can only measure gasoline, not blends (with ethanol or methanol added). What I'm trying to do is find out how much octane ethanol is adding, when I extract ethanol from the gas, but the issues are that I have to assume the advertised 95 RON is correct and that the actual additives in the gas vary and also change the octane properties.
If i were to use this to measure gasoline with a small amount of ethinol, even though my readings may not be accurate, i should be able to tell if one gas is better than another, correct?
With just the gas "as is" then sadly not, as even 2% ethanol will just give the maximum (false) reading. However as I've done in the past, you can extract the ethanol from both fuel samples, then test it to see which of the two might have better octane boosting additives made from a petroleum distillate, such as Shell V-Power, which contains considerably more than even top rival brands.
So I live in USA. I extracted 8% ethanol from 94 octane, and the meter read 82 ot 2 different samples from two different sunoco stations. 12 octane seems to be a lot for 8% ethanol. Also, I tested c16 race gas, which should be 116 octane, but the meter reads 84. Any thoughts?
No, it's an inaccurate reading as the ethanol has different properties--there's more oxygen in its hydrocarbon chain and thus is less resistant to what the tester is measuring for. 95RON "E10" (which is never 10% in the UK) is using ethanol as part of it's octane boosting additives, so would be only 95-96RON. The only advantage would be that it will aid cooler internal engine temperatures, which can be useful on small capacity turbocharged engines, but the difference on 5-7% (what E10 is in the UK) would be negligible, yet you lose considerable mpg by even just a small amount of ethanol in the fuel blend.
Hi there. Yes, I intentionally neglected to mention it as wanted the brand results to be known in a separate video. It was Esso/Exxon 98 RON, which as it turns out is actually lower octane than advertised. The tester (once I'd standardised the testing method) has shown to be accurate within 1 RON and shows consistent results on other brands such as Shell V-Power (99) and BP Ultimate (97). Thanks.
@@boilerhousegarageawesome! I guess I'll order myself one and see if it helps diagnose my annoying knock. The octane number it displays is basically the US octane/ AKI number? Did you find that the conversation it does is accurate (e.g 95 Ron reads 91 Octane on the same sample)?
@@112rorz I'm not sure how accurate the conversion is as only used AKI for the first couple of tests, or rather how it converts as I think the value it reads (a resistance) is converted to either rating type. Please note if you're in a state that doesn't offer ethanol-free gas, the tester won't work as it can only measure the octane of gasoline, not gasohol, E5, E10-even 1% of ethanol won't be testable.
What car are you experiencing the knock just out of interest? If you suspect it's fuel related, you can just buy the highest octane pump gas available to you and then add an octane booster, or order a can of race fuel.
@@boilerhousegaragerace fuel is super expensive here but I could give it a try. I'm in Qatar and I'm using the highest available gas. We only have 91 and 95 RON. We used to have 97. I have a 2013 BMW 650i which has a V8 N63TU engine. Recently rebuilt. I tested compression, it's still good and within spec. I have Bootmod3 and I flashed the 91 Octane map, but it still knocks. Even on stock map it knocks. Any idea what else can cause knock?
They're on eBay from Belarus. A lot cheaper than I paid too, about £150-£180 ($200-£230 USD). Mine was close to £300, from same seller. It took weeks to arrive because of another fake war and anti-British EU, but you may get it quicker depending on your location.
Yes, it's also strange not to have our own countries produce them, as I'm sure an item like this would sell well in the US and Europe. Around London, a number of people are suspicious that the gas station franchise owners are passing off the cheaper fuel as the top brand. Mind you, an ethanol test, which is easy and cheap to do, would also help in that instance.
I don't want less Ethanol I want more. Todays vehicles can run all day on E-Mixes. I run E30 on a 2022 Ford ranger 2.3l ecoobost. Stock HPFP and Stock injectors. The power increase is amazing. runs cooler and cleaner. The trade off is the MPG's. don't care, plus it is 80c to $1.25 cheaper per Gallon in the US.
Another great video 😎
Thanks Baz, I appreciate the support.
As always interesting content .Thanks for your time and work with UK fuels please keep it going .
Thanks. I'll be keeping it going, but becoming a bit difficult not having any facility to test them or store my fuel samples at the moment.

AKI = (RON + MON) / 2 ❓
So 97½/85½ yields 91½ [AKI]?
Looking forward to seeing more of these.
In general yes, but apparently there are variables on how MON is measured or that it's a minimum at all conditions whereas RON is not (from some quick reading that I didn't fully understand) so it makes conversion formulas a little imprecise.

how do you calculate the octane rating of a gasoline 89 octane RON + 10% methanol or 89 octane RON + 10% etanol ?
I can't. My tester can only measure gasoline, not blends (with ethanol or methanol added). What I'm trying to do is find out how much octane ethanol is adding, when I extract ethanol from the gas, but the issues are that I have to assume the advertised 95 RON is correct and that the actual additives in the gas vary and also change the octane properties.

Does measuring 110 means that E10 is ron110? or just wrong reading. is e10 95ron actually a ron110? or has less knock resistance than non ethanol fuel
No, it's an inaccurate reading as the ethanol has different properties--there's more oxygen in its hydrocarbon chain and thus is less resistant to what the tester is measuring for.
95RON "E10" (which is never 10% in the UK) is using ethanol as part of it's octane boosting additives, so would be only 95-96RON.

@@boilerhousegarage Thank you for the reply.
Hi. You didnt mention in the video or description what fuel you were actually testing? Was it 98 RON pump gas?

This is excellent stuff and much appreciated but honestly you don't need the background music, would be much better without it!
Thanks, but sadly I do need it due to white noise and editing issues. The music is covering bad tracks and splicing.
Perhaps if one day I get a decent camera with professional mic and "wind muff" (as they're called) I can do away with the music.
Even in the US you have to find that Russian Analyzer or pay ridiculous money for everything else.

And you should be given that option; as should the rest of us have the option to run pure gasoline, not ethanol blends.
Yes they all run on it but don't run your car for a few months and you will see the havoc that gets caused.
He also ignores that not everyone has or wants "today's" cars and most of us want them to last beyond the short service life "today's" cars have.
