Well, I decided to fill up on the way home today. It was a warm afternoon and this no EOC stuff is making the coolant fan run more than I'd like. It probably turned on about 6 times on the way home today. Ambient temp is around 57F.
Anyway, the fillup:
421.8 miles
8.9 gallons
47.4 mpg
Not too shabby. I honestly was expecting lower. The
scangauge was definitely reading low.
