After I drive the SUV for an extended period of time on the expressway(1-2 hours) and then its sits overnight I get a ton of smoke at startup in the morning. The smoke goes away after about 20 seconds. I don't see any excessive smoke during normal stop and go driving Im not sure if it is oil or fuel burning. Im thinking its oil because the more highway trips I take the more oil I loose. I talked to a Hyundai mechanic and he said it could need a tune up or it could be a dirty intake manifold where fuel is being absorbed into carbon deposits and burning off at startup. I personally have never seen that much smoke because an engine needs a tune up. Does anyone have any ideas what the problem could be or seen this issue with a Hyundai engine?

Does the engine feel like it has a misfire? You have to identify what kind of smoke it is. Is it bluish smoke and smells oily? Is it white smoke that smells really gassy and burns your eyes? Are you adding any fluids constantly? We need some more info please.

There is no check engine light on. The SUV runs good and smooth. No misfire. The smoke is light gray. I dont believe its coolant because Ive never had to add any. I do go through about a quart a month of oil. The more long highway trips I take the more oil I lose. This is why I believe the smoke is oil burning. I just dont see the blue tinge to the smoke. I wanted to upload a picture of the smoke but couldnt figure out the upload process.

Which engine? Maybe pull a couple of spark plugs out and read them. Does this have any oil leaks?
