Mine is a performance car- GT4. So I use a 99Ron fuel as that's what it was designed to run on. I always run the Mrs car on V~Power derv as she gets more mpg out of the tank. I used Archoil 6400 in the fuel and I couldn't believe the amount of grey carbon gunk that came out of the exhaust.

All the proof you need!

1. Redex
2. Oil & filter change
3. Spark plugs/ spark plugs leads change

They restored old banger to nearly new Brake Horsepower rating

Redex was the biggest single improvement - and the cheapest

For £1 a shot, you'd be crazy not to give it a go & see what results it gives you, no need to be more scientific than answer the before & after question: 'does it drive better/ smoother/ more powerfully? Yes/ no'

Still going strong, £2 in Wilko this morning - both for petrol & for diesel
All kidding aside... I do use it in my car.
It's coming up 22 years old and still has a carb! I'm happy to waste a few quid on it once or twice a year.
I drive very rarely and like an old fart... If anyone saw me putting premium petrol in my old car they would keel over laughing!
(I did try premium once or twice...no difference)

I own a skoda Felicia!
The one just before they went fuel injection!

Old skool! (Never goes wrong though!)

Much love all!
Redex helps restore power by cleaning carbon deposits etc. It won't increase power at all, most of that is a placebo. You may restore mpg not increase it. It's important to understand that.

The cars ECU is programmed in such a way as to run optimally in certain conditions, ie it detects 02 levels and increases or reduces injection rates, some cars are very smart and have variable timing and technical stuff like that.

Makes me laugh when people stick big bore exhausts on expecting 20% increase in power. Well the only way you'll get an increase in power is if you have your car remapped to take advantage of the better flow rates etc. Same with air filters, they increase air flow yes but unless your car is mapped to take advantage of that there is little benefit. Your car may detect higher O2 levels and you may benefit slightly but its within the cars default map you would just run at a more optimal level gaining perhaps 1% increase in mpg power etc.

Snake oil not really, it does what it says, but it isn't a miracle cure, it won't make much difference to an already clean injection system. It's like descalling a kettle basically. It could actually cause injection problems, if it loosened some carbon deposit and it got stuck in the nozzle it could actually cause problems.

Best way to keep injection system clean is by using quality fuel, or use a bottle of redex or similar product every so often.

redex buyers = uneducated or simply clueless how a modern engine works


If you drove my car you would not say that ( Mondeo Diesel ).
There is no doubt the tickover is quieter and smoother with redex in the fuel when the engine is cold.
To be fair , the slightly better throttle response at low revs is not so noticeable (though i notice it ) and it does not increase MPG by any noticeable amount.
But it definitely makes a difference and a £1 per fill up its worth it.

It made no discernible difference; over the next 10,000 miles I changed the motor oil three times (whenever Asda was having a sale at £12/gallon) and the oil that came out was noticeably less contaminated each time. From that (not very scientific) experiment I concluded that the best thing for petrol engines (especially older ones) is frequent oil changes, and that additives probably had no effect at all.

Redex doesnt do that, ZDDP additives supposedly can be poisonous to CAT's and DPF's (according to forum talk that is, and maybe some obscure info somewhere. Yes I get the irony that this is forum talk, but you have to take forum talk with a big pinch of salt.

I imagine it would have to be in large concentrations for it to do serious harm, some extra ZDDP being in your engine oil shouldn't even be reaching the Cat/DPF, well only in tiny amounts due to the tiny amount of oil being burnt.

I think the real reason for less ZDDP in today's modern engine oils is to do with cost, environmental impact and if your like me, maybe it's a bit too good for today's planned obsolescence agenda. Personally I wouldn't worry, the benefits out weigh the supposed risk. My family have used Extra lube ZX1 in 15+ vehicles, never had an issue with CATS. Used in Saab petrols, Mercedes Petrols, Subaru Petrols, Nissan Petrols, Renault Diesel, Citroen Diesel, VW Diesel, Kia Diesel etc etc.

And if you have an older diesel that didn't come with a DPF or an old petrol that is worth peanuts then you truly do not need to worry, in my opinion.

Some doubt it's benefits, but I think it does help clean youre injectors and it is an upper cylinder lubricant. Probably not going to make an extreme difference, but for £2 it's worth it. If you want to make an extreme difference to a rough running older vehicle then Extra Lube ZX1 and other ZDDP additives really do make a difference (though it is supposedly harmful to catalytic converter/DPF but some motor oils have it in anyway , though in smaller quantities these days unless you buy "Classic" motor oil). But I haven't had any probs and it always makes my familys used cars and motorcycles run smoother over the years. My dad first bought it from QVC circa 1995. Also put abit in the power steering fluid, the radiator coolant, never had any issues.

This stuff does work, 5th gear took an old GTI and it showed for the price it brought back the engine for about 20 BHP.

This doesnt just apply to older cars, I put 2 shots of this in a TDI Leon which had 15k miles, The engine now is quite compared to before and I top this up every 2000 miles (monthly due to the distance). 7 year old petrol astra without a turbo, this now wheel spins when you pull away.

Defo worth this.

Dont be fooled by the idea that the stuff that is in this is the same as what is in Vpower or prem fuel, Yes it will have less of this but the oct levels of the fuel are higher giving you the better fuel MPG.

Tends to up my mpg by about .6 any time I use it. Drops back down after a few weeks. Can't say it improves performance on my current car but used to drive an old Megane coupe and it would struggle to start sometimes. Possibly a placebo effect but seemed to sort it temporarily when I'd use it.

In the case of petrol cars.. doesn't this stuff essentially increase the octane rating of fuel to give the potential benefits? And therefore wouldn't using super/premium unleaded do the same job? Which you could get from Sainsbury's or Tesco for 5p/l additional cost making it roughly the same (normal full) price as this? Based upon a 45 litre tank it would be an extra £2.25 a tank.
I'm curious is anyone can tell me the difference between using this type of product now and then vs using premium fuel all the time and using both together. I've read that most premium fuels require usage of at least 4000-6000 miles on a petrol car before any real 'cleaning' occurs and before any potential mpg improvements would be made.

This stuff always makes me laugh with such melancholy. Me and my mate had just got into motorbikes and sucked down all the nonsense about stuff that makes them go faster and Redex came up and we got some and I was pouring it into my petrol tank and shooting it into the carburetor with a syringe while wailing on the throttle with it on the stand in my garden and my neighbour (who was probably in his 50s but we thought over 100 at the time because we were teeners) came screeching out of his house at pensioner pace swinging a spatula (that's fish slice to you weirdos) saying I was making his house like a 'gas chamber'. I'm genuinely crying with laughter over it now but actually feel bad because we were kids and thought everyone else was wrong about everything.

Suzuki A-100 if you need to know, and it was amazing. Bought it for £27 because it wasn't working and had sat in a shed for years and basically had a gunked up carb.

Depends how bad it is, in some cases the exhaust manifold and associated parts needs taking off and cleaning by hand. There are a few 'post' combustion cleaners out there that may be worth a try.

Since my problems I now drive the car (once warmed up) at 70mph for 5 miles every 3 to 4 week in 3rd gear, I was told by a local mechanic that this will increase the heat and exhaust pressure that will help with cleaning.

The best way to clean post combustion is intense heat, unfortunately the way most people drive the exhaust gasses never get hot enough for this to happen properly hence why the many problems with modern diesels.

First two things that come up with Google.Auto express … First two things that come up with Google.Auto express articlehttp://www.autoexpress.co.uk/car-news/33200/fuel-additives-are-waste-money



The autoexpress article is a news story reporting on a Which? test published in 2009. This tested octane (petrol) and cetane (diesel) boosters. Octane/Cetane are essentially measures of how effectively the fuel burns. The conclusion of these tests was that the additives tested did boost octance/cetane, but that they made no difference to economy or emissions and only small difference to power for the petrol variants.

These are different products from the Redex here, which are system cleaners. The manufacturer website is rather vague about what the product actually does or what it contains.

Super premium fuels (v-Power, etc) are higher octane/cetane, and claim also to contain more/higher quality additives. There is a wikipedia article about v-power for anyone who wants to know more.


I don't see why 'newer' engines wouldn't benefit from using this, unless they are self cleaning?¿????

the fuel is the issue that leaves deposits and crap in your engine........so regardless of the age of the engine if your using the same cheapo fuel it will leave the same crap in your engine......

newer engines are more reliable and probably manage better with the dirt, doesn't necessarily mean they are cleaner inside.

Sorry pal. Didn't realise that your opinion is more accurate than my … Sorry pal. Didn't realise that your opinion is more accurate than my experience.. oh and my mechanic mates.. oh and car experts who have done tests and reviewed the products.. Please explain then how a week into my full tank of fuel containing 250ml of this stuff in a 2.2 Honda diesel engine (one of the most reliable production engines) with 42000 miles on the clock and a full service history randomly managed to blow 3 out of the four fuel injector seals?? I hope you suffer the same experience and repair bill for your ignorance.

Fifth gear
youtu.be/VG3…kXs

Fifth gear did indeed do another test as described earlier promoting redex but it has been picked apart by viewers and there is even a thread on piston heads about it. The show was allegedly sponsored by redex and the dyno graphs show that the dyno "tester" let up and didn't take the engine to the same higher revs before the redex was used which essentially "fixed" the outcome in redex favour.

Speaking rubbish!! They actually did a test on it and they said it … Speaking rubbish!! They actually did a test on it and they said it dramatticaly improves the mpg performance of your car..!



Might want to check your facts... "Dramatically improved performance and mpg"?? They did a test on a car and gave it a full service and new spark plugs and commented that it improved performance by 5bhp mpg raised by 1-2 mpg (180bhp that's what a 2% gain and probably down to the service)? Is that a dramatic increase in your mind? If you actually look through the internet articles and find the video they had done 2 years prior all the evidence shows the stuff is as commented by numerous others "snake oil" and I know first hand it's not good for your car. Like I said before it "burns hot" talking to my mate about it today.. he confirms it burns much hotter than fuel to try and burn away the deposits in the engine and injectors and this is why it's not worth the risk of using as I found out it caused expensive repairs to my engines Injectors. But by all means call me a liar and use it.. someone will use it and seriously regret it. People are right.. just use higher quality fuel especially in diesels to clean the engine and prevent premature dpf blockages.

Thanks mudd, updated description as per suggestion.

Not bothered about the heat, but if it helps someone who uses this, it's quite a saving.

Don't know about the 3rd or 4th gear thing but when i leased my Diesel Infinity Q50 the dealer told me to take it for a good run at speed at least once a week to clean out the DPF if i was just doing local runs every week, if i return it clogged up i would have to pay for a new one.
cant find the diesel one online
Yes but to start with you also said drive at 60-70 in 3rd gear, this will all depend on gear ratios of a car. If I did this in mine I old knacker my engine as it would be redlining to the oint of over revving. But it can be useful if you don't do a lot or often to drop a gear when doing 60-70 on a motorway to help the DPF.
Thanks. This is ideal. The wife is due a service.
Adam786123

Don't do this you will definitely knacker your engine.



​Non sense adam. Whenever I have been stuck stationary for a long time, say a motorway closure, My DPF comes up and the onboard system tells me to keep driving with info to lower current gear. I.e. I did 50-60 in third and 4th gear for 70. worked fine. Burnt off the particles quickly. Once engine is up to temp of 90 then normal driving will burn it off as it runs normally. Spoke to my garage who advise on a colder start engine dont idle too long as the DPF will keep appearing. Need to either get to temp with driving ++miles or lower gears at higher speeds. A full DPF will certainly 'knacker' your engine!

rubbish, Redex cleans pre combustion parts, once the cylinder has fired the redex has been burnt away.
