I run toluene 121 octane mixed with a little methane in my 2001 gmc yukon and I get 25mpg. JK'ing i either run shell or ExxonMobil 87 in it and it's almost always in the 14's mpg which I'm happy with since it has 328,000. I've ran Sunoco and a couple local brands in pa and md here an it ran awful misfiring alot.

Several bad reports here about Shell being a problem fuel.
Honestly I noticed it burns slower.

Where I am at is either shell, kroger, BP, marathon, sunoco, and some RP brand I've never heard of.

Kroger when the points are high to get that $1.00 off gallon deal. Lol
