Cataclean Petrol | Complete Fuel & Exhaust Cleaner | Catalytic Converter, Valve & Injector Cleaner | Fuel Additive Formulated for Performance & Fuel Efficiency | Pre MOT Emissions Reducer | 4 x 500ml

I thought this would be a bit of a gimmick product but it really does work and I’ve got to say as long as you follow the instructions I think you’ll be pleasantly surprised how good it works. I will definitely be buying again and plan on putting this in once a year as my car is now starting to get a little bit older.

Great worked well in my car

Works well, just a bit expensive. Hence the 4 and not 5 stars.Had a small increase in mpg , and ran smoother. But you could just use any injector cleaner to get that result, to be fair.

Used this after PPF fault light illuminated on my Hyundai Tucson. As advised I poured a full bottle in to 1/4 tank of petrol and then drove up the motorway in 4th gear at 50 - 60 MPH. Occasionally let my speed drop down when safe and then floored it back up to 60. After exactly 30 mins the light went off! The car now feels smoother and more responsive to drive, and I'm no longer getting the bunny-hopping I was getting before when I accelerated in 3rd gear. I will be using this regularly every 3 - 4 months from now on.

Good cleaning product, use preventively !

Our Mini Cooper S had an issue with yellow engine management light coming on every week. If we gave the car a blast out round the block, high reving, it would clear. Obviously emissions build up issue.Put 2 bottles into half a tank to give it a good flush with Cataclean. 2 months on and the warning light has not come on again.Highly recommend.

Can't comment.Hoped it woul clear a 'Phantom' Engine malfunction caption but didn't.Too soon to see if any other benefits
