CatacleanDiesel Fuel & Exhaust Cleaner Catalytic Converter Valve & Injector Cleaner 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.

I use this stuff in my petrol and diesel cars three times a year and they run so smoothly since using it.

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.

Seems to work , passed emissions

Worked for me up to now.Had low idle on my van and constant white smoke, got to the stage my vaxhall combo 2014 dieasel van was undriveable.A mechanic advised me to try cataclean first before I looked at other options.I put the cataclean in my fuel tank with a quarter of a tank of fuel, drove it for around half a hour and no more smoke.I must say I got loads of smoke after I put the cataclean in but did stop after driving for half a hour.Still got van booked in for checks to make sure van is OK but cataclean worked for me.

Did not find the results that great

Excellent product, I took the car to a garage because the check engine light came on and got low efficiency reading on the catalytic converter. They said it’s at least £900 to replace it. I used one bottle of cataclean and the check engine light disappeared. The engine also makes less noise now. Would highly recommend
