This usually does more harm than good

could you explain this very negative comment for this product please ?

Yep - used this on 2 older cars and it cleaned away all the mucky deposits that were holding my exhaust together - sometimes it's best to leave things alone!

I have a VW diesel campervan (1989 model) would this be a good thing to add ?

comes in 2 - petrol injector cleaner and fuel system cleaner

Time to get a new car then.

What size? The 500ml was on offer down to around £4.25 I think at Halfords last week! I think it's a good product unless your car is literally held together with crap

Nice find! I think I'll get another crate again for this price Heat added. I find it works wonders; feels a hell of a lot better to drive and getter about 2-3 mpg more

Definitely hot from me thanks

redex is 2 quid in tesco from time to time

Used to use this many years ago, no idea if it did any good. Nowadays with modern fuels/engines I am thinking unnecessary. Possible 21st century snake oil!

This is great for older diesels. The newer ones don't like it so much

Waste of time. Do an Italian tuneup instead.

C'mon, stop playing at Click and
run. Explain your explosive remarks.

Good chance it will dislodge dirt, varnish and scum from your fuel system and block the injectors/ fuel lines.

I have used this stuff a number of times on my Honda civic (06) in the last 2 years but not seen any improvement regarding better mpg or smoother engine performance.

Am I expecting too much?
BTW I don't know much about the workings of a car.

I've used it in my newer Yaris. Worked fine. If anything, the newer Diesels need a fuel cleaner more as they are more fussy with carbon in the Diesel clogging injectors etc. Had many problems with my last Diesel (Had it 2 years from new) using supermarket diesel clogging injectors, EGR valve etc. I've had my current one 3 years from new and have avoided filling up at supermarkets where possible and used Redex the past 6 months or so on every other fill up and still runs fine!

It's not magic. You aren't likely to see any major mpg difference at all.

I thought they added a quantity of this kind of stuff to fuel by default anyway?

There's a forum talking about it here: pistonheads.com/gas…159

Some swear by it and some don't!

Tx OP, heat

I've never seen any documented evidence of this doing any good. You certainly shouldn't be using it regularly as it has been found to have adverse effects. There is some anecdotal evidence of it making a difference to really old engines, but nothing much for newer cars. You'd be better spending your money on a tank of premium fuel which has more of the additives that will affect your engine positively.

Asked at my local garage ages ago about this stuff. They reckon it's totally unnecessary with modern fuels

Better off with a tank of V-Power diesel, after 200 miles you can feel that, pulls better in higher gears and marginally more economical.

At 3p / litre more, on a 45 litre tank, V Power is also cheaper than Redex....

I guess Ultimate diesel would do a similar job.

vpower is 8p more a litre, but I agree what your saying. Need to sort my boost leaks out, im getting a lot of black smoke and poor mpg

We've been using the diesel treatment for about 10 years now and always in new car & pickup, currently Isuzu D-Max & Mercedes A200 AMG.
Never had any problems & yes you do get more power & MPG.

I swear this works, I get at least 1 mile extra each year

Costco quite often do 4 x 500ml bottles for about £12ish

I got these last time they were on offer. Just run out though! In think they're only about £12+vat full price there when not on offer anyway so still better value at Costco

Redex is basically paraffin (kerosene) as I understand it. A good engine 'cleaner', certainly.
Pure acetone (available from beauty suppliers) is also good in small doses.

But in the olden days Redex was sold as an 'upper cylinder lubricant' and I wonder if the 'formula' has changed much? We don't seem to have cars that need regular decoking, valve seat grinding or piston ring maintenance anymore.

I have used this a few times both on our diesel car and my motorbike - Haven't really noticed any difference in fuel economy / performance etc. My advice is use the £2.50 on buying the extra fuel - you WILL get more miles - guaranteed!!

That's a fact.
A sensible fact.


Good work.

ok if these products do not harm your car then could someone tell what they do good to your car. with evidence pls.

any concrete evidence.
or even a poor evidence.

this stuff is very good! only problem is they only allow 1 per house hold so that makes it very hard to get hold of at this price!

I use this every couple of months or so in my car (diesel) and I can definitely tell the difference. Even more so when I have used it in conjunction with vpower.

I use ultimate diesel the first time I used it there was a quite noticeable increase in power.. I also get just over 100 more miles per tank (peugeot 207) working out the maths.. It is just more economical to use than regular diesel. ..

Yes I agree with the above, I only use V-Power Diesel and there is a big change in miles and power. Those who know, know it works great.

Doesn't make a difference for me too

Redex is an Aircraft Hydraulic oil DTD 585 , OM 15 or Aeroshell 41.It is not Kerosene but can be used as a low temperature lubricant.

I have used it but I would not wish to comment either way as it is somewhat objective.
