I do that a lot, too...btw, what kind of mileage (mpg, that is) do you get? Last spring, I was getting like 31-32 pretty regularly (I drive on the highway a lot), but now I get ~28 or 29, even on all-highway trips in my 5-speed 95 ex.
The only things different about my car since then:
Changed tires to Goodyear touring radials (from stock(?) or stock replacement(?) michelins)
Changed timing belt
Switched from using 5w-30 to 10w-30 oil
Are any of these enough to make my mileage go down that much, or is there something I can do to increase my mileage to the previous levels?
I keep my tires well inflated and my driving style is pretty constant, too. Just wondering.
