How many miles are on the car ? That's valve seals most likely causing your car to burn oil. Very common problem and a very expensive repair.

Search "Valve Stem Seals", the parts is cheap, the labor not so much. It can range from $2000 and up depending on the mechanic doing the job.

Also check out https://www.agacoolantpipe.com/produ...stem-seal-tool , poke around and there are related videos. I can't say exactly how much , I traded my 2005 in because of the smoking and the secondary air injection problem. Some extended warranties will cover this repair if you have one.

Forgot to add that none of the oil thickener products helped in my case , stp , Lucas , etc , there's no mechanic in a bottle fix for this one.
