Does it work? What's the benefit?

Went in tesco last night price still £4... Cold

tesco petrol station, not store. seen and bought it in beccles suffolk, anyone else not able to get in their local tesco petrol station?

Didn't work with my ford with the anti misfuel nozzle - ending up tipping the lot over the ground...

It's supposed to clean out the fuel system, also improves fuel economy apparently. I used it in my diesel and it now starts a lot easier than it used to.

There was a programme a few years ago about this and other ones. they found they did nothing

HOT!

If you cannot get out to a Tesco fuel station to grab it, it has also been reduced
from £4 to £2 on tesco.com but only until tomorrow

begs the question why wouldn't the oil co's slap it in with petrol if it increases effeciency? BP could buy the formula and make their claim too fame!
all petrol has an additive detergent stuff in hats why

the stuff in this is already in fuel. it's basically additives.

your better off changing your oil more frequently than wasting money on this if your wanting you look after your car.

most cars these days use longlife service plans which means they don't get oil changed until every 20K miles which is crazy. I change the oil plus all the filters every 6 months costs me £100 to do but at least I know the engine will last and won't cause me expensive repairs. Previous car I kept to the schedule VW give and caused all sorts of issues on a brand new car, cost about £5K+ in repairs over 10 years from new.

so don't waste money on this and just service your car more regularly than what the manufacturer states

clean out the fuel system?

really? so what does a fuel filter do?

also placebo effect for your car starting easier. as for economy improvements that is also laughable.

i have some magic beans for sale too if your gullible enough to believe this product works

If your modern unleaded petrol car needs any more additives than what is already in the oil and fuel, then there is a problem with it.

The additive for lead replacement can be useful though.

is that also for DIESEL ?

Asda has 100% extra for the usual £4.00 ..so kind of like two £2.00 bottles

lots of negatives posted about this, but it was either 5th Gear or some other motoring programme that actually said this DOES work in ultimately giving you more power than any other small mod - and this was the cheapest. They tested among a few cars before and after on each mod and this made the biggest difference on a rolling road test.
Even though it was stated as the biggest difference in the real world not sure whether you would notice it, but you do notice you can go that bit further on a tank of petrol than before...I notice it and I normally put cheap Asda unleaded fuel.

It's called better quality fuel with higher octane....

If you want more performance then you must own a performance car, simply use better fuel.

Reasonably modern performance cars can adjust ignition to higher octane fuels and see fairly significant performance gains.

Usually at the normal price of these additives it's no more expensive to pay for the better fuel and you have the advantage that it is already graded and mixed properly at the refinery meeting all sorts of stringent specifications. On offer here this is cheaper, but I still wouldn't bother with it.

if your gonna buy it don't follow the directions imo.
for best results a full bottle when I have about 1/4 tank or less and give it a motorway run in 4th gear and it works wonders on my focus tddi 2001.but many modern cars I doubt it would do much.

And here was me thinking I could have a mature discussion on HUKD. Also the fuel filter cleans the fuel, not the fuel system.

The system cleaners generally work in my experience, I usually use wynns to clean the injectors in the porsche. Wasn't the TV programme in question testing fuel additives which increase RON which showed increase in performance but not MPG...... These are fuel system cleaners.

The ignorance in this thread is staggering. As someone who has a background in engineering and worked in the petroleum industry for a number of years, it's always a giggle to see the 'my mate told me' mentality being posted on the web.

Ahhhh, another sarcastic know it all.
You don't put this stuff into petrol because it's designed for short term use. Anyone who has ever rebuilt carbs and such will tell you the importance of using the correct cleaners so you don't damage the diaphragms and o-rings.
Putting Redex or any other cleaner into your fuel system constantly is not smart, and they do not tell you to do this on the product. Cleaner like this is a concentrated formula designed to shift mostly carbon deposits. It's perfect for a clean out once in a while, but adding it to fuel as a constant thing of this strength.......you're talking madness.

It's almost like the petroleum industry knows this isn't it?

PsychoSonny

No, it's not. There is a BIG difference between the additives added to fuel and a cleaner like this. The fact that you think this is "already in fuel" shows how little you know on this. You have absolutely no idea what you're talking about and clearly have no experience with petroleum.

Yes, because higher quality oil is going to help with carbon deposits and muck in your fuel system,

Please, please stop commenting on issues you have absolutely no understanding of. I can't believe you're implying the fuel filter has anything to do with what a cleaner will tackle. These cleaners are designed to tackle the deposits left after combustion and whatever other deposits have accumulated over time in areas like the injector. A fuel filter is for capturing small particles that have contaminated the fuel. A totally different job.

This is not an additive for performance. It's a cleaner. Big difference.

Right - some actual facts from someone who has worked for a number of oil companies

Cleaners and performance additives are vastly different things.
Cleaners are designed to remove carbon deposits and other gunk which might have accumulated over time. You should not be using these very often. They are great to put in your car every few years / lots of miles, and you will generally see a performance increase in cars that are older for obvious reasons.
The performance increases are not huge. You're going to get a few more MPG, not the equivalent of a new turbo charged car. Still, a higher MPG quickly pays for itself over even just one tank.


Performance additives are normally a con: youtube.com/wat…v3E - 5th gear is spot on with their testing / results here.
You can get legit performance additives, but you normally won't get them from most high street stores. You also need to have a properly tuned engine to make use of them, often with a custom mapping. They normally work by increasing the timing advance of the engine. People in this thread have spoke about using a higher octane fuel - again, you shouldn't just swap your normal RON95 fuel with a higher RON because someone on the internet told you your car will get better performance.
While higher RON burns more efficiently (generally speaking), there is a lot going on in your engine in regards to compression ratios, ignition timings, temperatures, how it's exhausted (and sensors being calibrated). Some vehicles will have systems which can adapt to higher RON, even though you won't get a huge advantage out of it. Check your handbook, as it should be very clear on which RON you can use. If it can use a higher RON properly, it will say so - the manufactures want to show a higher MPG as it helps with TAX, their environmental obligation....but in general there is a reason they don't. And that's because the car isn't set up for it.

In short: a cleaner like Redex is legit. BUT you can't keep putting into a vehicle and get gains. It's a cleaner. Once it's clean, putting more in isn't going to help. If you have no deposits that have to be cleaned, you don't get any improvement. Cleaners like Redex are mostly suited to high mileage vehicles and / or to clean your injectors.
It is not advertised as a product to increase performance every time you stick it in your fuel tank so stop using this point.

I know HUKD is renounced across the web for it's hilarious computing advice, but the comments in this thread are just an extension of that. Multiple people have not only misrepresented what a product like Redex does, but are issuing 'advice' that is demonstratively false.

It's linked above, but watch this 5th gear video and listen to what they say: youtube.com/wat…RkI

Redex / cleaning products are fine for what they do. When people misrepresent what they are for and argue against a point which the manufacturers never made, it all starts getting a bit ridiculous.

Original Poster

Right. ... I agree that the way to use it is an empty tank £5 of high octane petrol drive at higher revs in lower gear than you normally would. Will then improve start up .fuel economy , and better response. This is personal experience. Plus at this price better than a £100 self service every 6 months

nomnomnomnom

This is not an additive for performance. It's a cleaner. Big difference.



I never said otherwise in my post that you quoted here. Please point this out- if you can. At no point in that post did I suggest the cleaner was specifically a performance additive. I stand by my statement, a modern unleaded vehicle maintained and run correctly should not really require any sort of cleaning additives. This is not the 1960's, where engine manufacturers recommend de coking their products every 10k miles or whatever....

The title makes it clear that there is cleaner, and there is lead replacement. Redex lead replacement is not an octane booster, although some other lead replacement additives are.

My second post (the one you didn't quote) is really meant to implicate octane boosting additives, not the cleaners, hence me talking about octane.

Original Poster

Lead replacement, unless i'm being dumber than normal, is for vintage vehicles like my old Landrover, which I always use high octane in any way. Also try comparing milage between 95 octane supermarket can barely be called petrol and 10p more a litre BP or she'll 98 octane. Pays for it self

It's important to note that in that Fifth Gear programe Redex only "recovered" 6 bhp or 3% of the original on 18 year old car. I'd like to see more testing done including with newer cars before jumping to any overarching conclusions.

Proof it works, especially on older cars as a one off treatment. Also proof you know nothing about your car (if you even have one)

Magic beans? You must have a magic fuel filter if it cleans your injectors etc.

I've used this before on a car that was losing revs whilst driving; after a full dose of this, the injectors were cleared and it was running like a dream. If you don't believe it works yet have never used it before, that's your call; however I've used it before and can vouch it does work

I disagree entirely and feel even a 0.3% increase in power would be conclusive proof this product works as intended.

Great post! Listen to this man!!

I noticed performance increase in my Lexus IS200D diesel turbo. Due to lack of care from previous owner, it had a flat spot about 4 second (meaning no acceleration immediately after pressing the throttle). With 3 or 4 rounds of Redex Diesel, no more lag. Just immediate surge of power when you overtake. For those who contemplate putting Redex into their cars, If this doesn't tell you whether it works or not. I don't know what will.

Snake oil.
