Engine
It is advisable to change the oil in the engine entirely after every 2,000 miles running or sooner.

Gearbox
The depth of the oil should never be less than 1" or more than 2½". It can be measured by a rod inserted through the filler hole. The gearbox should occasionally be washed, after 4,000 or 5,000 miles, out with paraffin.

Rear axle
Attention every 1,200 to 1,500 miles should be sufficient.
