RedexRADD0050A Petrol Advanced Emissions Reducer 400ml

Mot emissions failed I brought this after having some work done also and seemed to work well, car ran smooth and good for a while!Will buy some more and test again soon. Thanks! Good price too.

I’ve always used this product a week before my mot at due.Always passed the emissions test.

My 2007 BMW 318i petrol driven car which I'd owned for eight years failed it's MOT on 7th November. Had no previous issues and this was my first MOT failure ever. The garage did the usual when it comes to 'failures' such as this - "it could be this or it could be that" - nothing definitive. The car was not worth much so in danger of being scrapped if the fix turned out to be too costly. I reluctantly agreed to replace the Lamda sensor (£150 + £60 Labour so £210+). Booked car in to get sensor changed 21st November. In the interim period I bought this stuff and put it in a half fuel tank. Drove it for a week. Filled up with Shell V-Power premium fuel. Inflated tyres to maximum load pressure. The weekend before garage visit drove car very hard and kept it in 4th gear max - did 40 motorway miles at 70mph/3400rpm. Took car to garage to get sensor fitted next day. Dropped it off not feeling positive. But when I returned that afternoon the garage staff told me that before fitting the new sensor they did the emission test again - guess what it passed without any issues. I enquire to the receptionist "How much do I owe you". She says nothing - MOT retests are free! I'm not categorically saying this stuff made the difference - but when you are faced with issues such as this - especially on an old vehicle, where MOT failure could result in an otherwise good car being scrapped - you have to throw everything at it, in the hope that it makes a difference. For £10 this is certainly worth a punt.

Was a bit sceptical about this stuff, but bought it as the price was really good compared to the shops. I poured the full bottle into half a tank of fuel and then drove for about 30 mins. On the early mornings, I used to have some white/greyish smoke from the exhaust which cleared up after the engine warmed up. I can say this is no longer the case ! Highly recommend this stuff, for the price it's worth a try !

I don't normally do reviews but I felt I had to...We have a kia Sportage which was juddering when flooring the acceleration. I mean juddering.. the car felt like it was going to fall apart and was so down on power. Best of all it's only 4 years old. I took it to the local garage and they couldn't find the issue. They checked the spark plugs, ignition coils etc but no solution.A diagnostics was booked at Kia for £180 just to diagnose the issue and a few days before I decided to just give this stuff a try combined with premium fuel 99Ron.Within hours it felt better but I didn't know if it was a placebo. The very next day the car was driving even better than it had before.I can only suspect the something was clogged within the fuel system or maybe I had a bad tank of fuel but it's saved me hundreds of not thousands on replacement parts and still running well now. I'll keep using this stuff once a month I think.If your car struggles with the same then it's worth a go.

Great price and arrived quickly.Did the trick and lowered the CO on the retest.Thanks

I have a 2006 Toyota Aygo. I realised it wasn't running all on the new petrol. I was sceptical, but found this worked.

Well satisfied
