Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!

Hi Retze
From your report on the symptoms of your problem, it definitely points to an electrical problem, which is aggravated by cold and damp.
The smell of fuel in your oil, points directly to a misfire and non combustion on one, or more cylinders, and the subsequent unburnt fuel washing down the bores and into the fuel, thus breaking down the viscosity of your oil, and going to give you premature , and excessive wear on your engine before too long, if not already.
As you say loosing oil, which I expect is going out the exhaust, due to ring or piston wear.
This problem must be cured quickly !
I would firstly suggest, all the spark plugs are removed, and inspected very closely for contamination signs, from oil or fuel.
This will hopefully give you a clue, as to the problem cylinder/s.
Also a dry and a wet ie:- ( injection of some oil in the cylinder ) compression test should be carried out, on cold engine.
This will tell you if your valves, pistons and rings, head gasket,etc are all serviceable, from the pressure readings.
A master guage should also be connected, and your oil pressure checked to give your oil pump, and lubrication system, to hopefully give it too a clean bill of heath.
Now as to my gut feelings as to where your problems may lie ?
I too suspect the spark plug coils, as they are problematic with BMW, as they are also, with my specialist subject, Jaguars.
They are sometimes difficult to fault, as the problem can be intermittent.
And usually the clear sign is the spark plug condition on removal, which is the give away !
I am also very concerned as to how long ago you changed your engine oil & filter, as if you can smell the fuel in your oil, it must be thinned down considerably, and also affecting your hydraulic valve lifters.
Mind you if worn or faulty, you can usually hear the problem.
Your first line of attack is remove the spark plugs, and inspect those plugs !
Let me know what you find, and give me your feedback as to your thoughts on my comments.
Good Luck !
Remember to give me a rating if you think I have been of assistance, thanks !
