If your car looks like a rocket ship with blue smoke streaming out of your exhaust, chances are this is a head gasket problem. Oil is probably leaking into the cylinders and burning there.
Why is my Mini Cooper burning oil?
If the engine is pushed too aggressively, the piston walls can get too scratched up, leading to oil burning issues in the future. The break-in procedure is very simple. Just make sure to keep the first 1,200 miles under 100mph and 4,500 RPM. Then be sure to change the oil at 2,000 miles.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs.
Can too much oil cause blue smoke?
Yes, there’s a possibility of blue smoke being caused by the overfilled engine oil. This can occur when the crankcase is over-pressurized due to the sump being overfilled. Consequently, the additional oil will be forced up the cylinder wall and into the combustion chamber.

Can faulty injectors cause blue smoke?
This can be caused by worn/leaking injectors or restrictions in the air intake system. Blue smoke is normally the result of engine oil entering & burning inside the combustion chamber. This is most often caused by low compression, or worn piston rings.
Can thin oil cause blue smoke?
It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke. Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise.
