Gas type for better gas mileage?
I have read a few responses to this, but I
definitely need some clarity. I have a 14’
explorer flex fuel. When I do E85 gas mileage
downgrades as opposed to putting regular in.
Now, what gas type should I be putting in to
get the best mileage I’m able to? Or is that
how it works? I don’t want to swap better
mileage a for quality by any means. ( I don’t fill
up at random stations, I usually head to either
chevron or shell). I don’t understand any of it
please bare with me lol
