Isn’t it the check engine error code never return after the test drive. That means the lacquer thinner works. I use Cataclean last time I have problem with my Honda CRV because of valve clearance problem and after valve adjustment my CAT is dead that I can feel the backflow in acceleration. I use it in quarter tank of gas until empty because before the second time I follow the direction in the label of the product and it only work a little bit but I know it did work it just my cat is way dirty. Last month I tried lacquer thinner after watching Eric’s video with a pint in half tank and drove it to empty. Now I noticed my car breath better and have a better pickup which is almost like when it’s new when I first pickup the car in the dealership. I also remember using aviation gas in our shop service car when I’m aircraft mechanic, car never have any engine problem for using aviation gas which is 110 octane. It’s just quiet and fast, our shop car is ugly and rusted but everything under the hood is well maintained by a handful of aircraft mechanic back then. High octane should not be a problem unless you race the car for a long period of time or your cooling system cannot handle it. It’s just purely clean burn… lacquer thinner did work on my Honda CRV to clean the cat from after valve adjustment.
