Engine Break-In Period
The break-in period consists of the first 25 hours of
operation, or the time it takes to use 15 gallons (57 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. Refer to Chapter 2, “Engine Oil Level”. Check oil level
indicated on dipstick. Add oil if necessary.
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. Change oil and oil filter after 25 hour break-in period.
