This seems kinda kewl.

First let me tell you I only have been running 87 octane with each and every fill up, and temps were NOT constant…nor were AC usage or drag with windows, towing…well you get the idea.

I only have a few choices when I fill up, but here is what I have found so far:

Mobil
Texaco
Shell
Citco
Sunoco
Gulf
*GOGO GAS - surplus fuel *crappy I am told*

When I fill up, I am usually near dry…so as little mixing is going on as possible, but I have found that when I fill up I get better MPG when I run Mobil fuel in the truck. So I have been running Mobil all the time. I am probably the only weirdo that has been doing this…but has anyone else tried it?

I know this is not a PERFECT test...but I would like to try it in a controlled environment.
