Hi my car is Nissan Maxima 2006 3.0 gcc spec the car use very high oil consumption with no sign of leaking and smoke from exhaust. I am using total 5w30 for 10,000 km and now my car is 5,000 km and I lose one liter oil. What I notice only is that at cold start up if open door car smell exhaust until warm up with no sign of smoke coming out from exhaust. So where is the oil going? There is no leak and no smoke I am one hundred percent sure.

Good afternoon,

The oil is most likely burning out through the engine. The reason you do not see any smoke is from the catalytic converters and the muffler are collecting the oil inside. The catalytic converters are burning it off.

The rings are the most common cause for this. You can confirm it by have a wet and dry compression test done. If the dry compression reading is good and you add a little oil in the cylinder and the compression raises up then you have worn rings.
