The details:
2007 Forester 2.5x Prem
53,000 miles
For the last 2 months, mainly driven around down for short distances under 50 mph
I was calculating my economy pretty regularly over the summer and was getting 25+ mpg. I was also driving mostly highway at 50+ mph.
This winter my economy has plunged, to 16mpg for the most recent tank. It may be worth mentioning that I recently had the one-way valve removed as part of the Subaru recall at the dealership. For a few days after picking up my car from the service department, I could smell raw gasoline. I figured this was just leftover leakage.
Here are some other possible contributing factors to the decline in fuel economy:
It has been 30s and below for the past two months where I live.
I have been driving in snow every weekend.
My spark plugs have never been changed.
Transmission and diff fluid has never been changed.
I am running Mobil1 5 w30 and have been since I bought the Forester brand new.
I do not let my car idle for more than 5 minutes in the morning.
I just refilled and put in a bottle of gumout, so I am anxious to see the number next refill.
Is this just a product of crappy winter gasoline mix, or do I need to get my spark plugs changed?
Thanks for the input, as always! :Banane35:
Mmmmmm, I'm actually drinking a beer right now...Sweetwater IPA
