So the light is changing and i am not sure why. I am like 1500 miles till the next oil change and like 7500 from the 60,000 mile check up. The car is running fine besides the mpg being a little lower then normal, but i think the hot weather has something to do with that. So can some one shed some light on why the light is slowly changing for green to yellow(which it is on now) to red? i would appreciate any help
