Default smoke from exhaust

Why would a 1994 Mitsubishi Galant ES let out smoke from exhaust when you step on the gas?

If it's oil it will be more noticeable when first accelerating. It's probably a weak piston ring, valve, or something letting oil into a cylinder. Drain the oil and put in a full synthetic oil like Syntec (Yeah it's not cheap oil). If the smoking stops or drops significantly then it's an oil problem as a full synthetic won't produce hardly any smoke when burned. It's a cheap way to find or eliminate a that possibility.

Blue smoke is oil, white is coolant, and black is fuel.

Hi new here, I have a mitsubishi lancer 93 model. Same problem with my car. It produces white smoke. But I can't hardly distinguish if white or blue. But sometimes it produces lot of smoke, sometimes no smoke at all. What could be the first step to do? I had a change oil I think this February or march with a semi synthetic oil. Any tips?

Get a long stick while car is in park...Press the Crap out of the accelerator and it will show...If not that then do a Load test-Basically just drive up a hill and accelerate rapidly.

I personally would do a compression test, also check your oil and coolant levels too.
