Quinster Posted October 9, 2016 Share Posted October 9, 2016 Simple as that. Bought a bottle and thinking of using it. The car was running slightly sluggish and idle (when hot) wasn't happening. The EML came on but after getting the code (o2 sensor) someone suggested giving the car a bit of a kicking as I'd only been using it on short journeys for a few weeks. That seemed to solve the problem as the EML went off and the car seems to be ok now. Would it be sensible to use Redex in the tank? Has anyone used it before? I've never used it but thought it might be a good idea to try it. Just looking for advice before i go for it. Cheers. Robert. ps I usually run car on BP Ultimate (97 RON) if that makes any difference. Quote Link to comment Share on other sites More sharing options...
Ekona Posted October 9, 2016 Share Posted October 9, 2016 Redex is quite weak stuff, mostly just kerosene so it's unlikely to do any harm at all if you use it in the recommended doses. Also unlikely to do any good either Quote Link to comment Share on other sites More sharing options...
Bandit Posted October 9, 2016 Share Posted October 9, 2016 If you want to elect a Pope put it all in. Why bother run it on proper petrol ?. Quote Link to comment Share on other sites More sharing options...
Ekona Posted October 9, 2016 Share Posted October 9, 2016 Actually, which Redex did you buy? And why did you buy it if you're not sure about using it or not?! Quote Link to comment Share on other sites More sharing options...
Quinster Posted October 9, 2016 Author Share Posted October 9, 2016 I just thought it might be a good idea at the time after the o2 sensor problem,thought it may help clean the engine a bit. It's no big deal, it was only £3. The reason I use 97 RON is because it's hard to get anything else locally. The nearest Shell garage is about half an hour away. The car runs fine (normally) on 97, As i said if it's rubbish I'll not bother, it's only 3 bangers. Quote Link to comment Share on other sites More sharing options...
-G- Posted October 9, 2016 Share Posted October 9, 2016 Your fuel might have spoiled if it's been left in the tank a a bit is all, you get stabilizer fluids to stick in petrol tanks while keeping cars in storage to stop it occurring - redex won't hurt IMO. Try that first and give the car a blast with fresh fuel, should notice a difference - if not, back to the drawing board. 1 Quote Link to comment Share on other sites More sharing options...
Bandit Posted October 9, 2016 Share Posted October 9, 2016 Put a chunk of Redex in and give it an Italian decoke for about 20 miles up the nearest motorway, job done. 2 Quote Link to comment Share on other sites More sharing options...
Quinster Posted October 9, 2016 Author Share Posted October 9, 2016 Well,it seems like it won't do any harm, I'll be filling up tomorrow or Tuesday I'll do it then. Thanks for the help lads. 1 Quote Link to comment Share on other sites More sharing options...
Ekona Posted October 10, 2016 Share Posted October 10, 2016 Also, BP Ultimate is fine to use, no issues there. 1 Quote Link to comment Share on other sites More sharing options...
brillomaster Posted October 10, 2016 Share Posted October 10, 2016 recently put a bit of redex in an old track car, figured it has been ages since it had been serviced and for the sake of a fiver, why not try some redex in the fuel tank as well. to be honest cant say I noticed any difference, but then I wasn't expecting miracles for £5. I think giving it a decent thrashing on track was the best tune up, I suspect in the 40,000 miles it had done before I had the car it had never seen north of 3000rpm. 1 Quote Link to comment Share on other sites More sharing options...
Juggalo Posted October 10, 2016 Share Posted October 10, 2016 Redex...just don't. I'm not a big fan of snake oil, least of all Redex. But if you absolutely have to, then buy Wynns. I know from experience that at least some of their products work. Like valve seal reconditioner and stop oil leak on previous cars. Quote Link to comment Share on other sites More sharing options...
Diggerman Posted October 10, 2016 Share Posted October 10, 2016 cataclean all the way me, tried and tested over many cars and proven to work safely and effectively unlike the redex crap Quote Link to comment Share on other sites More sharing options...
Holfy92 Posted October 11, 2016 Share Posted October 11, 2016 I put cataclean in my 350Z and it got rid of the EML which came on due to an o2 sensor/cat. Hasn't come back on since.... Quote Link to comment Share on other sites More sharing options...
Aashenfox Posted October 11, 2016 Share Posted October 11, 2016 (edited) Hm... http://www.motoringa...cataclean-work/ http://www.asrcrevie...-fuel-additive/ Standards organisations say cataclean is snake oil too, beyond the fact that it's main benefit is designed for diesel engines...Plus, the testing evidence was submitted confidentially. Not illegal, but also pretty shady. It's like an athlete refusing a non-mandatory drug test, on it's own it's not an indication of guilt, but it certainly looks really bad... I have not conducted any independent tests personally so cannot speak on the validity of the above content. Take it at face value and draw your own conclusions. It obviously did something for Holfy (unless Holfy, you hoofed it when you wouldn't normally have, in which case, you know what I'm goinna say, that the act of hoofing it is what cleared your problem, not so much the additive. Tell me I'm wrong by all means, I'm always a bit cynical about additives.) Edited October 11, 2016 by Aashenfox Quote Link to comment Share on other sites More sharing options...
coldel Posted October 11, 2016 Share Posted October 11, 2016 Its interesting reading the response from Cataclean, that they actually had no evidence on record apart from 'motorist claims' that their product worked and actually they were hoping to get use of a facility at some point to prove their product. You would have thought that proving the product works before putting the claims on is a start point, not a point that you consider if you are challenged on your claims. Highly suspicious Quote Link to comment Share on other sites More sharing options...
Richf Posted October 11, 2016 Share Posted October 11, 2016 Redex does work its not snake oil but the detergents in it are largely found in fuels like V power anyhow Back when I was racing dragbikes I would soak my valves in redex and it would help to dissolve the carbon build up and make them much easier to clean 1 Quote Link to comment Share on other sites More sharing options...
coldel Posted October 11, 2016 Share Posted October 11, 2016 I don't think its a case of if it works or not, more that there are some very dubious claims. Cataclean for instance claims 60% less soot on its marketing without actually having anything other than some customer comments to prove it - which is quite frankly, illegal.

It had absolutely zero effect on the piston crowns and valve heads. That's why I categorise it as snake oil. Quote Link to comment Share on other sites More sharing options...
evest Posted October 11, 2016 Share Posted October 11, 2016 Can't see the value on a well maintined modern engine that uses premium fuel and is regulraly driven. It won't cause any harm though so if you really want to know, just put a bottle in and see if there is any improvement. Quote Link to comment Share on other sites More sharing options...
Holfy92 Posted October 14, 2016 Share Posted October 14, 2016 Well I put in the cataclean in the fuel tank when it was 1/4 full. Didn't 'hoof' it at all, driving sensibly. Didn't really go over 4.5k revs over the first week. This was couple weeks ago, still hasn't come back on and car seems to be running fine so far.... 1 Quote Link to comment Share on other sites More sharing options...
Diggerman Posted October 14, 2016 Share Posted October 14, 2016 they must have changed the product and or advertising as it used to be petrol only ie cat instead of dpf and was shown by mot test stations the difference in readings from sniff test that it was a mild cleaner Quote Link to comment Share on other sites More sharing options...
