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

At first inspection i was impressed with the product size.I have found that this product has had a positive impact on performance figures for my high mileage car.Mpg improved and overall engine performance data improved on my obd 2 system data graph.It is something that is recommended as a repeated application not as a one off and I will do it every 3 months I feel that this will keep my car running smoothly.The price i paid seems fair for the outcome I have had and I do not have any criticism of this product.I am giving this 5 stars.

Had an yellow engine light on for long time the car garage didnt do nothing about it only was clearing it and it was always coming back untill i found this and it helped no light on for now hope it stays off.Thank you

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.

I've used this product before and was pleased with it

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.

I was recommended this by a friend who swore by it to get me through my emissions test for mot.The car it went in was a 1994 Toyota supra twin turbo. Last year's mot was just about a pass for emissions(very close to the limit) and where parts aren't readily available for my car (if parts are available they come with the added jdm supra tax!). I thought I'd give this a go.I had a little too much fuel in my tank but was a bit scared to use this with the less stated fuel to cataclean mix ratio considering the car is old and has a £6000 engine, which I was scared to cause damage to.Mixed it into a 3rd of a tank of superunleaded (+25 litres approx). Let the car idle for 10 minutes to get up to operating temperature. Then cruised at 50 to 70mph for about half hour.Feeling confident the mixture was safe for the engine I started driving in lower gears doing hard pulls in the car. I drove this pretty much close to empty didn't take long considering the type of engine it is. Then filled up with super unleaded.1 week later it had its Mot and passed with flying colours! Well within the emission limits and actually surprisingly almost too low on the Co figures.I now swear by this product and will be using it throughout the year to keep the fuel and emission system as clean as possible. Car drives alot smoother, and pulls a bit quicker too. I did a 0-60 before and after to make a comparison and it was 0.45 seconds quicker after the cataclean.

Doesn't seem to be doing anything good
