Refineries change the fuel blend every spring and fall. Warm weather and cold weather blends. Mileage changes with the blends.silly question- have you checked your tire pressure? It’s common to need to add a few PSI when temps drop from 50+ to below freezing.
Figured I’d throw this in…. Winterized fuel will net lower mpg. This may changed from supplier to supplier. You will notice this more with Diesel motors between the months of November through April depending on how far north you live.On a side note…anyone see the decrease in mpg’s with the cold weather? I lost roughly 2-3mpg’s once the 30-40 degree temps hit. ?
I really wish you'd stop being logical about such things. Science-based solutions are just not acceptable.How to improve mileage
