One and ONLY gas mileage thread please

^ driving around in first gear?

I use e-30 and have gotten as low as 9 mpg but also as high as 24 mpg on long 55 mph drive. Snoball I averaged about 12 but had to use some crap e-10.

Single digits. Yes. That's where I'm headed.

I think you need to gas it more off the line and let it coots to the next stop.

If you didn't know I like e-30 it's good

I have the 5.4L and I run ethanol free gas, I have a farely long commute going up and down hills and I average about 15.8 mpg. I don't know y'all's insight with eth free but I only got 13.4 on regular

Solid 11.8 on the 5star Perf 87oct tune. Ready for a fillup and a 93oct tune.

Are you talking 10% that stuff sucks. You need 15 or 30%

Yes, I'm talking 10%. Could you explain why it sucks? I drive a lot during the week and the extra mpg is more important than power to me.

I haven't reset in a few months holding at 12.8. That's about what I got with my 5.4L, too.
