For maximum performance and longevity, the engine oil
should be replaced after the first 8 hours of operation.
After the initial oil change, it should be changed every
125 hours of operation or semi-annually, whichever
comes first.
The selection of oil is dependent upon the service that
the vehicle will perform. Most vehicles require 10W-30
oil, whereas vehicles used at capacity or near capacity
load applications will utilize 10W-40 oil after a break-in
period of 100 hours.
