added air to my tires.

So... winter months coming... temps dropped and I noticed that my mpg's went from consistently 43+ to anything in the 40-42range. My last tank (although a small tank) was 40mpg's.

I decided that there were 3 main factors.
1: car taking longer to warm up
2: Tire pressure had dropped from 40psi in the summer months to 32psi currently
3: Due to colder temps... air resistance is higher due to the air being more dense.


Can't do much about problems 1 & 3... So I pumped the tires back up to 42psi.

First tank afterward netted 43.71, which is the higherst i've gotten since august 31st. Haven't noticed any difference in performance/handling or comfort either. So I'm happy with my 1-2mpg I gained back.
