Greetings all. Has anyone ever used fuel injector cleaner to improve gas mileage? If so, what is the best to use?

Thanks,
Nelson

Stuff like Techron, only works if the injectors are dirty, to improve mileage. If they aren't dirty then it won't increase mileage. I use Chevron fuel all the time because all their grades have Techron in it.

Redline Sl-1 is also good. You can find it locally at Advanced Auto Parts.
