For the past ten years, ONLY Chevron Supreme Unleaded, never a drop of anything else, never! No exceptions there- the car lives a HELL of a lot better than I do

It costs more, but the result is that at 117,000 miles the injectors are just fine and the car has always run beautifully, never a problem, under any condition.

I have heard that Chevron Supreme with "techron" additive supposedly cleans the injectors as you drive, and that gas has worked well for me, and I guess I will still keep with it, it's easy available anyplace in California, though its not cheap..
