I'd regularly use top tier fuel or injector cleaner if using unbranded gasoline.I don’t have fuel economy or rough running issues. Is it a good idea to use an additive as preventative fuel injector maintenance?
Help keep valves clean (wishful thinking). After seeing dirty injectors when I replaced them, I'm hoping it would help. If it gave the vehicle a little more pep off the line, that would be a bonus. But ya, 3rd gen dirty injectors. 😠What problem are you hoping that the Lucas additive might solve?
How many miles were on those injectors and what brand(s) and grade(s) of fuel had been used?
