As the title reads, tell me your MPG. I wanna if this minor misfire is causing a drop in my mpg or if its the fact that i'm driving a 10 year old car and it really is getting this crappy mpg. A huge portion of my driving is highway at 75mph, I shift around 3750-4k change my oil on schedule and if i'm lucky i'm getting 260 per tank. My car is bone stock so if your car is too that'd be good and if your's isn't lemme know what you were getting when it was stock.
