"Smoke emissions after using Cataclean nearly insignificant. Marvelous staff!"
Nick Reynolds
"I added Cataclean to my truck w few days before the MOT Test (Ministry of Transport). It not only passed but the emissions were lower than last years, Cataclean clearly works on fuel consumption and emissions."

"I have used this on every car I've owned since 2009, it has proven it's worth every time I've used it, restoring engine performance, responsiveness and smooth running, my latest car, a 2006 Hyundai 1.5 turbo diesel developed issues, very poor cold starting, lots of smoke, torque was poor, it ran rough and was lacking power, put a bottle of Cataclean in with 5 gallons of fuel and a couple of days on she's running like new, some lads on Youtube say it's a placebo effect, that is definitely not the case, it might take a few hot runs to sort your fuel issues out (unless you've got seriously worn injectors/pumps) but it definitely works."

"A customer’s car came in to rectify a drop in the compression ratio, so we asked customer for permission to test Cataclean on the vehicle. Initially we applied Cataclean then ran at idle, we followed this with a shorter period at a higher speed, then left the vehicle for 1 hour. We then opened up the cylinder head to check the results. Normally, the combustion chamber and cylinder head will be covered with stubborn soot/carbon deposits, which we have to scrub continuously to remove. After Cataclean we simply had to wipe off with a rag...Amazing!!! We love it!."

"My Saab 9 e 1.9 tid was running badly ... Lumpy and the mpg had dropped to 25.3!! Had wafts of black smoke from exhaust.
Got some Cataclean and emptied it into my tank. Then I took the car out for a drive. I could tell it was smoother after about twenty miles. Got home and checked the mpg .. Up to 43 which it where it normally is. The power is back and it is showing me 44 mpg now, no black smoke and smooth running. I am very pleased and will order another for the three month treatment as recommended."
