I've just bought my first BMW last month, it is a 2006 325i E92, automatic with 48k on the clock however it seems i'm only getting 15MPG! This is with mostly London city driving. I have a black box fitted so I was always stick to the speed limit with low revs, would the MPG be normal for this car? would appreciate if anyone can tell me what they are getting on theirs?
I have changed the spark plugs which hasn't improved anything and will change the oil and air filter sometime this week.
It seems I also have an oil leak because I topped it up to about the 3/4 mark but after driving 400 miles in 3 weeks it is has dropped to a 1/4. I took it to two different garages who put it on a ramp and checked it however the could not find anything. There is however some oil around the oil cap area and I have recently found some drips of something on the bottom tray between the windscreen washer unit and engine (pic attached) , would anyone have any idea what is causing this?
Any help or tips would be much appreciated!
