Ok, so I was recently bought a 2008 Mazda 3 sport with and automatic transmission. You see I have been getting around maybe 24 mpg and I have read these questions before saying no jack-rabbit starts, check your tire pressure, and empty your trunk but I mean i have done that and maybe increase my mpg by about 1 mile. Does anyone have maybe an better less generic tip maybe and product I could buy for my car or maybe some specific kind of oil. Please it would be very much appriciated!
