The smell of burning oil isn't scary. But to make sure the engine oil level is normal and there's no oil underneath, either under the hood or under the car. The smell appears on a vehicle at a speed greater than 120 km/h and at a speed up to 60 km/h, as well as a "aggressive" driving behaviour. The smell can be seen during off-road movement. The smell is due to the burnout of oil in the units and mechanisms of the car's transmission due to increased friction and heat in the rotating parts. The main thing is that there's no oil.
