Average mileage per gallon decrease
I've been tracking my mileage using mileagetracker.net since April and here are my results so far:
April - 21.29
May - 19.64
June - 19.46
July - 18.69
My driving patterns haven't changed and I always make sure my air filter is clean so I'm concerned about the decrease. All I could think of is the weather has been getting noticeable warmer but I'm not sure if that should have any effect at all. Any ideas?

What filter do you use? Ever try cleaning out the MAF sensor? Try a fuel injector cleaner. It bumped my MPG from 18 to 25 and now its steadily decreasing to 22 over the past 3 months.

I've had the JWT air filter for 2+ years now and I do use a fuel injector cleaner once in a while. I'll look into cleaning the MAF sensor. Thanks for your suggestions.
