I would like to know whether my car is running properly....ie burning too lean or rich ,whether the injectors/cylinders are functioning to its full potential(compression test)......Because in my head.....i think gas consumption is on the up side in the city at 13.....according to OBC......

Ever change the O2 sensor? My car was a pig, and when I changed it, fuel consumption dropped to 9-10 L/100 avg combined (actual, not OBC). I was getting 15 combined before, so it paid it self off very quickly.

Hmm, then it could be a simple vacuum leak, bad plugs, or a clogged air and or fuel filter.
