91 octane vs e85 in flex fuel Tahoe/suburban?
Which of these is better? I wanna save money of course but if 91 octane overall will increase longevity of the vehicle than by all means Idk if it matters but the winters are harsh and the summers are hot here.- iboughtatahoe23

How to change charcoal canister and evap?
2014 Tahoe LT 176k miles. Every few dollars the pump will click sometimes. Seems to be worse in cold weather. Always has done it since I got it. Sometimes it does it. Sometimes it doesn’t. Sometimes I also smell gas when I first start it up in cold weather mostly. Than goes away pretty quick...- iboughtatahoe23

Is E85 in the winter bad?
I’m reading that it can cause rougher idle and other symptoms in cold weather because it takes longer to vaporize? I’m thinking about switching back to 87 this winter. It’s already below 40 on the regular and it’s gonna get colder until It hits -40 with windchill this winter- iboughtatahoe23

10.9 mpg? Is it bad?
Usually use e85 so I expect that from e85 but now I’ve been using 91 with no ethanol and I still get 10.9 mpg average.
