Octane Poll

[1BAD454SSv2]

Arizona has Crap 91 , Cobb Acessport says it more like 90 to 89 by knock counts . last 2 months I run 6 gallons e85 to 20 gallons of 91 . i can run the Cobb OTS stage 2 93 octane tune on this ,Ecm its always adding timing as well. Truck runs really strong , soon to get a E50 Tune from Goose.

I have always used 44K for the plugs in most of my vehicles.. I was once told that is what a lot of mechanics use when they tell you they are cleaning your fuel injectors. Difference is, they charge you a lot more for it.

I'm a big fan of BG44K, I run 2 cans/bottles every 10k miles since new, amazing stuff.

Same as other, best I can get in California is 91 octane.

91 no ethanol, top tier fuel.

Reading this topic , I notice, some, absolutly don't know, first , that E85 octane is higher (105) than others regular gas and second, how work E85 in your engine ... A part of ethanol in your engine could be better than you think, perhaps better than without... (About to not use truck long time and have potential moisture in the tank, that's another story...)

One of my favorite parts of moving from the West to East Coast is the availability of 93. Not sure how it is in other states, but Washington had next to nothing for 93 options.

Blessed to be in TX with 93 everywhere.
