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
necessar
y (Refer to Chapter 2, “Engine Oil Level”).
3. Drive slowly at first to gradually bring engine up to
o
perating 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
impo
rtant bolt torques.
6. Pull only light loads during initial break-in.
7. Change oil and oil filter after 25 hour break-in period.
