I have a 2012 Sonic 6-speed manual LTZ turbo and I have been getting great mpg, about 37 on av and better than 40mpg on the Highway. The car only has about 76000 mi on it. during to past couple of days I noticed that my mpg/gal indicator is telling me that I'm only getting 26 mpg/gal. The tire pressure is good. Perhaps I am in need of a tune up?
