Huge decrease in MPG

[btripp31]

My last 2 tanks of gas I have noticed a 4ish MPG decrease. Does anyone have any thoughts on why?

Mine goes down every time cold weather hits due to using the remote start and letting it idle to warm up more than usual. I don’t think it’s down 4 mpg though

Cold weather + decrease in tire pressure. Mine dropped 5 psi with the recent cold snap. Really affects gas mileage driving with under inflated tires.

Big right foot?

mine dropped this past week due to extremely cold temps (below zero). It went from 17/18 to 14/15. Suppose to ”warm back up” (20’s) later this week.

Negative, I drive like an old man.

I'll check the tires, not much I can do about the cold

Cold and winter blend fuel. Not uncommon.

Any issue with head winds?

Yup. I was going to say winter fuel.

Winter fuel for sure and you have to keep check those tires as the cold weather comes in and then again as the weather warms up in the spring as you will need let some air out. I will say that since the pandemic it seem like the loss in MPG in the winter seems to me to have been worse than before. It seem like I have seen a bigger drop in the last couple years at winter time. New blends?
