GEN 2 Gas Octane Question

[adeerchaser]

I use diesel in mine. Raptor is maybe a coach seat on Southwest. You know, that emergency exit seat without a seat in front. Poor mans first class.

Easy now dammit, Southwest is written on the checks that paid for my Raptor.

91 for sure, and if there was higher, I'd pump it in!

If the manual says 87, I'll use 87. It's just a knock rating - if Ford says the engine won't knock with 87, then putting in 91 is just wasting money.

If they say that the engine will adjust, and you'll get better performance with 91, then I'll probably try it to see if I can tell a difference. If I can, then I may use it on occasion.

I know things have changed for High altitude higher octane availability over the years. Last year I stopped a few places in CO in small towns that did not have above 89. Ethanol free is cool just don't tell @Wilson I said that.

Southwest is my favorite. Won't fly anything else unless the boss man buys me a first class ticket so he isn't lonely.

Yep, 91 ethanol free octane!

Amen to Ethanol Free !!! I loose a solid 2 mpg in my 2011 FX4 EB running the standard ethanol shit here in Alabama versus ethanol free of the same octane.

Is adding ethanol something states decide?

In my daily travels in MI. I don't see any ethanol free gas. I see a slight difference of increased fuel economy between 87 and 91 on my truck. I would only run the higher octane in the 2017s.

The Federal Government subsidizes the production of ethanol gasoline as a means of reducing dependency on foreign oil reserves, with the added benefit of ensuring demand for our corn crop. I'm not sure how much influence the individual states have over what they'll allow and what they won't allow. In Alabama, they run 10% ethanol. Unfortunately for us, the energy density of the gasoline-ethanol blend is lower than pure gasoline, thus our HP, Torque and gas mileage drops. Ethanol will also disassociate out of gasoline, becoming water over time, which everyone knows is not a good thing in your tank. Ethanol also tears the hell out of marine engines and things like lawn mowers, edgers and chain saws, as the alcohol destroys the gaskets and seals. Products like STA-BIL can help minimize the damage caused by ethanol gas.

You can go here to find a listing of non-ethanol gas stations in your area, though it's not updated nearly often enough to be truly reliable.

Good luck.
