Few days back I changed my car's engine oil, and now its average mileage is decreasing constantly.From 12.2 its 11.9 now. What should I do? Anyone who can guide?
Corolla 2009bmanual.
Avg doesn't seem that much down
Wht oil grade were u using before and what grade did you put now?What was the odo reading when you changed oil and what's the reading now... I mean in ho much run hv u calc the avg
I agree with sleeper. It seems to be a very minor decrease in fuel average. Maybe you put in a thicker oil grade? Please give us more information. Did you only change the oil? Did you get anything else changed or did the mechanic do some "tune up" of his own?
Are you mostly in-city driving ?
