Had a sticking injector someone pointed to the new fuels as the reason then suggested 2 quarts of motor oil to a tank to unstick the injector and keep using motor oil as a fuel lube. Injector has been fine and I have been adding motor oil to fuel since situation.

Been using name brand cetane boosters and fuel lubes/cleaners and wonder now If ashless 2 stroke or just plain ole motor oil is better as fuel lube?
