Engine ran on a standard 10W-60 every year. Engine experienced engine wear throughout Dakar rally because of sand ingress. Also occasional drop in oil pressure.

The gearbox was operating at more than 130°C sump temperature during a 12h endurance race with the current transmission oil. Outside temperature was approximately 17°C.

Overheating differential in BMW E46 M3 GTR. Differential cannot be filled with 75W-140 because of used oil cooler. Therefore a 75W-90 differential oil with exceptional wear protection is required.

A torque converter transmits power from the engine to the gearbox. When it is not locked, it constantly slips, generating friction and heat. The 2019 Beast used a Swepco ATF, which would burn every day, forming lacquer and causing problems.

Fluidity problems occur in the MKR truck when using a liquid grease. Also possibility of misapplication between different parts of the truck, such as transfer case, differentials and hub reductions.

Engine is developed for competition use. All engines are sealed, only performance benefits can be achieved by altering lubricants such as the engine oil. The Eurol Racing 0W-40 oil has been extensively tested in practice.

The sequential gearbox is equipped with dog clutches as synchronizers. These are often subject to high wear, as they need to engage while the vehicle is operating under high load.
