Home Forums Gear Hunting Trucks and Four-Wheel Drives Why does you fuel mileage decrease in the winter?

I would go insane with happiness if gas was 2.09 a gallon its 2.55-2.57 a gallon here

I know they change the gas but I think having the fluids in the differential, transfer case, and engine turn into taffy has a lot to do with it. Check your oil when its -20 sometime. Try to pour some gear oil. You'll figure it out.
I just got back from a trip to South Dakota with my F-150 with the five speed manual and 4.6 engine. I got 20 mpg on the way out with no wind. Bucking wind on the way back got me 15 mpg. I think there is a LOT of wind resistance. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
