i have a BMW E 36, 1995 Auto Saloon 316i I've discovered the MPG is very high, i am getting 20 miles to the gallon
first port of call i did a full service, its not coding, the service made little or not difference, so i replaced the O2 sensor
and its still the same, i have used injector cleaner and fuel treatment.
The car is running like a dream so i don't know where to go next, i understand i should be getting 28/30 so its quite
a considerable amount, if anyone has any ideas i would be very grateful.
