You engine is almost identical as far as what controls oil.
I assume that you do not have leaks.
Pull the plugs. Do any look oil fouled? Do they look the same? Set them in order side by side, and make notes. Perhaps installing new plugs.
Add some oil treatment that claims to free sticking rings. If that is the problem, then it might be all that you need. Use twice if neccessary. Use a crankcase flush with the next oil change. Follow the directions carefully. Use a good quality oil. Synthetic will help free up stuck compression rings and oil control rings as well.
Give the car some serious miles to allow any freed rings to reseat themselves. Monitor your oil consumption.
If you blow smoke when you start the car, the intake valve(s) are leaking oil. This could be a problem with stem clearances, or perhaps there is a valve stem seal missing.
If you smoke when gearing down, the oil is comming past the cylinder. If you smoke under hard acceleration, there is a serious compression problem.
Find where the large crankcase ventilation hose goes. Into your intake system somewhere between the air filter and the throttle body. See if you can get into it and see evidence of oil. Also look into the throttle body, with the throttle open. Do you seee oil in the manifold below? This oil would indicate heavy blow by from the engine.
Try the chemicals first. Then mechanical solutions can be considered later after you see what the chemicals do.
I have seen the chemicals take a car that was a smoker to low oil consumption. Did this for someone who had obtained quotes for an egine rebuild. Yes there is a lot of hype and bogus claims. But they really can save an engine. The cost is very low.
