Engine Break-In Period
The break-in period consists of the first 25 hours of operation,
or the time it takes to use 14 gallons (53 liters) of fuel. Careful
treatment of a new engine and drive components will result in
more efficient performance and longer life for these
components.
1. Fill fuel tank with unleaded fuel which has a minimum
pump octane number of 87 = (R+ M)/2.
2. Check oil level indicated on dipstick. Add oil if necessary
(Refer to Chapter 2, “Engine Oil Level” ).
3. Drive slowly at first to gradually bring engine up to
operating temperature.
4. Vary throttle positions. Do not operate at sustained idle or
sustained high speed.
5. Perform regular checks on fluid levels, controls and all
important bolt torques.
6. Pull only light loads during initial break-in.
7. Change oil and oil filter after break-in period at 25 hours.
