My drives are usually 2-3 miles in length so the car is warming up for most of the short trip which contributes to my horrible gas mileage. But this is 99% city driving (stop and go, 25-40 mph etc...) Last week I tried getting into 5th gear as fast as i could with manual mode and this netted me around 16 mpg. I really wish i could get 17.5 mpg or higher but as far as i'm concerned my car seems to be running well. I think the circumstances are causing the bad mpg not something bad with em or the engine.
I logged my car awhile ago, but did not record a/f ratios is this something i should do to see if i may be running to rich?
