how many other people are getting a lower FE lately?
i was consistantly 41-44mpg in august/september...
now im down to 38-39mpg.. i put synthetic in last tank... and i just fueled up the morning & got 40mpg. is this (or worse) what i should expect all winter?
not that im complaining... my gas bill is sooooo much lower than last year this time so far this month i have spent $107 on gas. and that includes travelling to races in Vt. Maine, Ct. Mass, etc... typically once or twice per weekend... last year this time it was more like $300!!!!
Cold weather = lower fuel economy for a bunch of reasons.
9 reasons why your winter fuel economy bites (not all neccessarily apply to you, since some are maintenance or driving issues you can correct):
1. More idling 2. Lower tire pressure 3. Increased rolling resistance 4. Crappy road conditions 5. Lower average engine temperature 6. Higher average lubricant viscosity 7. Weaker gasoline 8. Higher electrical loads 9. More aerodynamic drag
