Gasoline
 

I use Chevron becaause it is in the Top Tier gasoline rating for engine cleaning with its Techron. But I have heard that Texaco is actually rated nationally to give the mest mpg. Is this true?

I've never heard anyone credibly claiming fuel economy increases from certain brands. Shell does, but I don't consider it credible.

I don't consider fuel additives credible either. Buy what's cheapest, you'll benefit more that way.

...most likely "marketing speak" more than "technical fact"!

Actually scientific studies have been done and Techron is shown to reduce sludge.

So you have those papers, right?

Guess what happens when you mix Shell V-Power and Chevron with Techron?

You get V-tech, y0!

*Sorry, had to.*

...here's a linky: Our Fuels: Fuel Additives: Techron Concentrate Plus

...however, 99% of realworld cars don't achieve anywhere near the stated benefits they claim, so "yes" while it's technically "true," it sure ain't practically true.

All Techron can do is help to reduce sludge. I was asking a separate question really. Sorry for not being clear.

I use Chevron because it's convenient to my route. I'll use 76 or Mobil also.

I'll use Shell or Mobil; neither one (here at least) uses ethanol. Both are convenient and typically priced well.
