What is the explanation for my non engine meltdown?What is the explanation for carbon build-up, engine meltdown, burned valves, scored cylinders, etc, especially when ridden gently then?
I can't see how running a strong fuel system cleaner can be blamed for numerous tanks of poor fuel economy.
Try Techron next time (if there is a next time).
The only engine meltdowns I've seen on here happened shortly after botched valve adjustments that nobody wants to admit to. Or running engine mods such as complete exhaust systems with a poor fuel mixture retune.
Fuel cleaner has no/ poor energy density compared to actual fuel and I don't run my tank dry every time so it took a few fill ups to get rid of it all.
