Liqui Moly Aero

Liqui Moly Aero

With the correct oil friction losses in an engine are reduced to a minimum. This is done by taking into consideration circumstances as engine usage, ambient temperature, time of year and climate, location and engine design. The engine manufacturer usually recommends a certain type of oil to use with regard to different circumstances.

Lubricating oil plays an important part in the life of the engine and during maintenance it will be replaced, on certified aircraft the pilot can only replenish it.

Without lubricating it the engine would fail within minutes, keeping a watchful eye during flight is therefore important.

Having a basic understanding of engine oil is a must for the professional and private pilot, here we can only scratch on the surface of a very interesting subject.
