Being in the fuel industry you'd be better off filling up at a branded fuel station eg Shell, Esso etc as their fuel contains additives already. Their more expensive range of fuels eg Vpower etc will after a while make your car run better and get more mpg and responsive vehicle. Ok it costs more and you don't necessarily notice it on one run but after a while you will notice the difference.
As you would know working in the industry all fuels have additives. It’s part of the EU standards. The premium will have more hence the increase in cost. I don’t know whether it’s coincidence or correlation but when I fuel system failure and talk about fuels most people are using Vpower. Each fuel will have a different additive and if you always use the same fuel you can get a build up of additive, probably the cause of component failure. The reason you can feel the ‘ boost’ effect when switching fuels is that this can clean out the additive buildup.
@@glchow First try was fill the tank on top of a single bottle of emissions reducer, and within 20/30 miles, the engine warning lamp disappeared! 👍 It came back next time I topped up more than half a tank. This was all about 3 weeks ago. I tried the system cleaner next, but didn't read the words and added the whole bottle instead of half. After a few miles the service warning light came on. I kept topping up and eventually was back to the engine light. I know my intake needs a clean out, but a bad back stops me working on the car for more than just having a quick look at the EGR. (Very sooty!)
A 10 second squirt of GT85 with PTFE or WD40 in your fuel tank will do the same job and it's far cheaper. They both dissolve carbon and clean fuel lines at the same time. Garage trick I learned many years ago.
Tried them all over several tanks and different conditions. Only one product actually worked. ATS 505 CRF. Stuck it in as per instructions, drove keeping the revs high (3-4k) for 20 mins, then normally. Without the high revs these products tend not to work. But........after this product my mpg has gone from 26 to 30 mpg in a very well maintained vehicle. The only change was the additive.
I've never used this in my diesel car. The last time I had to put stuff in was 2 years ago for an emissions failure, my mechanic told me to put a bottle of Diesel Magic in the tank. I'm not sure about performance but it did the trick for my MOT. Is Redex the same type of stuff as Diesel Magic? Cheers 👍
@@glchow Yes, ours is cheaper. It about $3.89 here in Texas which is $1.02 per liter. But our smaller diesel pickups (Jeep gladiator) get 25 mpg. We don't really have smaller cars that run on diesel. I think our older VW diesel cars used to get great milage because of their small engines and light weight.
I added two and it got rid of the dpf light that came on but next tank of fuel I’m gonna see what mileage I get soz I didn’t realise it was diesel additive my stuff was dpf cleaner but that did job I needed
It can’t hurt it. As others have said I believe it’s just kerosene, a cleaner. I would imagine the injector version is a stronger mix. If it was damaging the package would need a warning. I ran 2 bottles though with no issues
Thank you for commenting. One of my viewers said that the main ingredient is kerosene. This is designed to clean, but I guess it could increase the explosiveness of the fuel ? I didn’t notice it on my test.
We went to Torquay twice from South Wales and on the first trip I used a whole bottle of Redex, on the second trip I used a whole can of Liqui Moly super diesel additive, I found Redex was better, the car had better pulling power and the gauge didn't move until we got to the camp site, we were towing a trailer and the first trip we had more to take with us, the second trip with the Liqui Moly the car did seem quieter however pulling the same trailer which was lighter this time struggled up the same steep hill and had to drop into 3rd gear. Overall for us the Redex was the better additive, our car is a 1.9DCI 2009 Grand Scenic if that makes a difference 😅
Thanks for your feedback. The best part of posting these videos is getting other drivers perspective and this was the inspiration for this test. The redex does not have any cetane boosters so I cannot increase the explosiveness of the fuel, but does help with upper cylinder lubrication and may lower exhaust temperature. Maybe this means the egr /cooler is not being utilised as much? Hard to test for. I initially got some remarkable economy, but the engine quickly re-tuned this out.
@@glchow I don't know how dirty the fuel system was, the car is a 59 plate so it could have just had a good clean. The Liqui Moly I can't quite figure out why it worked the way it did, It could just be one of those things.
I’ve used this stuff for about 8 years, 250ml every 3 full tanks and I’ve never had a fuel system problem with my Vw 2 litre engines. Costco do 4x 500 ml bottles for about £14.
So add half a litre of additive. Do miles refill with half a litre less diesel because you added 500 mil of additive and yes you will do the maths and achieve more mpg. Got to do prim to prim re fill.
@@zipper121 Aldi have been selling two for a fiver for a while .....I thought it'd help compensate for the amount of small journeys I've been making 😊
Just use shell nitro diesel for a couple of tank fulls, no messing about it will easily outmatch any additive, the BP or Esso premium will do the same. Unfortunately you knuckle draggers have been duped.
All you needed to do was fill the tank full and do a 100 mile run without additive , repeat run twice and note AVG fuel consumption on digital display . Make sure driving conditions and wind are similar during experiment . Put in additive and do a motorway run in 4th gear. Then do some hard acceleration bursts to up psi through injector and fuel pump.. get the engine hot and make sure you are stressing those injectors with enthusiastic driving. Change fuel filter. Then fill up fuel tank , make sure the temperature outside is the same, no rain. And also switch off as many ancillaries that draw current as you can, heaters , day time lights , radio etc Do the same 100 mile run and return back to petrol station and note how much fuel is needed to refill the vehicle , and note digital mpg . Do this twice . Then you have a reasonably accurate conclusion. You cannot test while diesel additive cleaner is in the tank when its acting as a cleaner for the whole fuel system . Give it a chance to work and log data accurately after you have give the vehicle some high revs and enthusiastic driving. I found your review quite unhelpful im afraid and i think some basic knowledge of your fuel system would help you understand that the additive is only part of the treatment. God bless and thank you for your video. Next time out in two bottles , drive it higher revs than normal , some hard bursts of acceleration.. refill just with ordinary fuel and keep being enthusiastic avouding idling.....then fill up again and watch your mpg To vlbe honest people just yse BP ultimate once a month , or shell Vpower diesel. They have additives in them already. But dont forget to be enthusiastic with your driving while its running through yout fuel system . Sorry if some of the Choir are here in the comments and im preaching to them 😂..
I think you need a basic mechanical knowledge to run these tests accurately. To actually scrutinise the product fuel filters should be changed after tank number 1. Also , the valves need inspected as do injecters. I am pretty much against adding anything into the fuel tank of a well maintained vehicle. However, you really need to understand that the product is meant to be a fuel system cleaner and not an immediate gain of MPG. As I said, I do not buy into quick fixes and do not believe in pouring additives into a fuel tank! Also, to add....even wind direction will effect mpg test results! The only test I carried out with fuel was carried out on a rolling road. The instigation for this was a misfire under load when using Sainsbury's unleaded. ( sierra cosworth 4x4 371bhp ) I wony insult people by explaining the results! But basically, Redex is a product meant to keep your fuel system clean....if you ate doing service correctly then you replace these fuel system components anyway! Only benefit I see is a low mileage vehicle using Redex every month to keeo a clean fuel system not subject to maintaining like Valve, Injection, inlet ( coke buildup) etc Nice Idea, but not a good test. Better to check results after 3 months of using with new filters. If it helps keep a fuel pump of SCV operational and clean then it sure pays for itself. Or not 😂
Thanks for the feedback. This was a real world test and not a lab/workshop test. I would love to have the workshop and time to complete a more thorough test but until then...
The benefits of redex are mainly after use, so the 57 result was helped by the previous redex clean
Don't worry, Starlin will add quite a bit more to the price of a litre in a few weeks so your saving won't mean much at all.
😂😂😂

@@glchowwhich is the best premium diesel ?
@@Thuds593 In principle they are all the same, because the fuel comes from the same refinery. I would recommend changing brands regularly
All fuel is top quality nowdays. Most importantly, new/newish garage stations.
Those 30years old tanks have some gunk floating around after decades!
Agreed, thanks a good tip. @@gimigimi1299
My local Tesco Superstore has Redex at half price if you use a Tesco Clubcard. So I bought twice as much!!!!!!!
I saw that too. Let me know how you get on with the Redex

I just add 2-EHN to every Tank been doing this for over 15 yrs ! Engines have ran like a dream
Thanks for the tip. I’m currently testing some different additives

try it without additive you'll get same results
Thanks for your support for the channel. Comment below with your questions?
Fun fact alert , Redex was used on Lancaster bombers during ww2 . 👍🇬🇧
That you I had not heard that.
Millers ecomax is one of the best 50ml to 50 litres used it for years.

I’ve never heard of diesel magic, but it could be? Commenters have told me it’s just kerosene?
@@glchow I have no idea what's in it to be honest, but it sorted my emissions out mate.
Did you take into account wind direction ie strength of wind?
No just the Coriolis effect 😂
Wow, we don't get kind of mileage here in the states, amazing.
I bet your fuel is cheaper! I have to eek out every last drop due to the crazy costs in England
@@glchow Yes, ours is cheaper. It about $3.89 here in Texas which is $1.02 per liter. But our smaller diesel pickups (Jeep gladiator) get 25 mpg. We don't really have smaller cars that run on diesel.

UK gallon is different
3.8 Liters USA
4.5 Litres UK
With most new diesels up to 2L 50mpg should be expected at almost all times ....
Better engineering over here in Europe. I've driven some horrific stuff in the states
I’ve got a 2017 Ford Edge , normal operation MPG was 34.7 after one bottle of Redex I got 37.7MPG-works for me.
Thanks for your feedback. Hope is continues to work 🙂
The price of the redex you would of been better off putting another gallon in and probably got another 50 miles.
I added two and it got rid of the dpf light that came on but next tank of fuel I’m gonna see what mileage I get soz I didn’t realise it was diesel additive my stuff was dpf cleaner but that did job I needed
Thanks for your feedback
I bought the Petrol System Cleaner for my bike my bike is Carburettor not fuel injection can i still use it?
It can’t hurt it. As others have said I believe it’s just kerosene, a cleaner. I would imagine the injector version is a stronger mix. If it was damaging the package would need a warning. I ran 2 bottles though with no issues
Fuel injection injects fuel. Carburettors suck fuel. But fuel system cleaner will work for both (if the system does actually needs cleaning).
I have noticed whilst using redex my idle is slightly higher than just straight diesel.

Redex is good.
just use the best diesel possible and make sure you do drive it hard when possible .
Did you notice any improvements in engine performance?
No unfortunately not
is rhino diesel any good
I’ve not heard of this, maybe I should look into it
Liquid moly is the only one ive tried that works. Gets a dirty diesel through the mot.
Agreed, you should try the mannol super diesel. Pretty much the same but cheaper
Try a tank of just Redex, no diesel.
🤣🤣🤣
Redex and Redbull ftw
I use 1 litre of automatic transmission fluid every oil change at 4000miles in my old hilux keeps everything clean and lubricated and get 28mpg
So are you putting the oil in the fuel or the engine oil?
@@glchow In the fuel tank ,atf has loads of cleaning agents and keeps everything lubricated ,might be a bit thick for modern diesels

@ sometimes I stick a full 500ml bottle in a full tank if I’m doing a long trip
Redex is mainly paraffin
Thank you. I guess paraffin is a good cleaner, and burns well too
I added 50ml to my mower, have I wrecked it? 😮
So add half a litre of additive. Do miles refill with half a litre less diesel because you added 500 mil of additive and yes you will do the maths and achieve more mpg.
Got to do prim to prim re fill.
I always fill the tank to the second click off. On some cars filling up too much can damage the evaporative loss system
Redex does not increase fuel mileage. It does a great job of making the engine run well
A poor running engine will consume more fuel.
YOU ARE NOT GETTING MORE MILES TO THE GALLON YOU HAVE ADDED MORE FUEL
Thank you for your review
Stick a glug of 2 stroke oil into your tank,,, been doing this for years..
What are the benefits ?
Let's not forget the price of the redex
£2.5 on local tesco offer. Keep your eyes open. As soon as you get cheaper buy more
@@zipper121 Aldi have been selling two for a fiver for a while .....I thought it'd help compensate for the amount of small journeys I've been making 😊
ok you get say 30 more mpg per tank for your £10 of redex or 90 miles for two gallons of diesel at a £10 lol

Chuff all happens.you could add 10 and there ain't no difference.
Redex is not very good Archoil is much better
Thank you. I’ve not heard of that product. Maybe I should give that a test?
does nothing its rubbish
Agreed
Yeah it's a con just like the V power diesel vs normal,

its funny because you talk like you know what you are talking about. Not many people replace their injectors normally (for example)
