Losing power as I was driving along and blue smoke came out of exhaust as I revved the car
SOURCE: Blue Smoke and Oil Level droping
This may sound odd but my saturn with 225k does not push blue smoke with the A/C on.... When A/C is off it will start to pushing blue smoke... Any guess out there>>>>
SOURCE: blue smoke from exhaust
Blue smoke is a sign that oil is being burnt in the combustion process. It is normally a sign of high engine mileage. Definately a compression test would be in order to try to pinpoint the cause. In addition to high mileage it could be something like a broken piston ring or a valve not seating properly. It might also be possible that you turbo has a bad seal and is putting oil into the air as it spins. This problem should definately be looked into soon. Hope this helps.

You might have transmission problem. It could be low fluid level or could be an internal transmission failure. I suggest you to have the fluid level checked for quality. Another thing you can try to reset your transmission. BMW transmission would help you to know about the transmission better.
The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. 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. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.
Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.
Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.
