Break-In Service - Northern Lights M50C13 Operator's Manual

Check engine oil
A- Engine oil dipstick
IMPORTANT: DO NOT fill above the top of the
crosshatch pattern or the FULL mark, whichever is
present.
Marine engines installed at an angle will have an alternate
pattern as identified by the dipstick remarking process to
compensate for installation angle.
Oil levels anywhere within crosshatch are considered in
the acceptable operating range.
Northern Lights Break-In engine oil should be used to
make up any oil consumed during the break-in period.
IMPORTANT: DO NOT use Plus-50 or Plus-50 II
engine oil during the break-in period of a new engine or
engine that has had a major overhaul. Plus-50 or Plus-50
II engine oil will not allow a new or overhauled engine to
properly seat during the break-in period.
IMPORTANT: If Northern Lights Break-In or Break-In
Plus engine oils are not available, use a SAE 10W-30
viscosity grade diesel engine meeting one of the
following:
• API Service Classification CE
• API Service Classification CD
• API Service Classification CC
• ACEA Oil Sequence E2
• ACEA Oil Sequence E1

BREAK-IN SERVICE

The engine is ready for normal operation. However, extra
care during the first 100 hours of operation will result in
more satisfactory long-term engine performance and life.
DO NOT exceed 100 hours of operation with break-in
oil. GENERAL ENGINE SPECIFICATIONS on pages
74-75 of this manual for oil pressure and coolant
temperature specifications for your engine.
1. This engine is factory-filled with Northern Lights
Engine Break-in Oil. Operate the engine at heavy loads
with minimal idling during the break-in period.
2. If the engine has significant operating time at idle,
constant speeds, and/or light load usage, or makeup oil
is required in the first 100 hour period, a longer break-in
period may be required. In these situations, an additional
100 hour break-in period is recommended using a new
change of Northern Lights Engine Break-In Oil and a new
Northern Lights oil filter.
IMPORTANT: DO NOT add makeup oil until the oil
level is BELOW the ADD mark on dipstick. Northern
Lights Engine Break-In Oil (TY26661) should be used to
make up any oil consumed during the break-in period.
3. Check engine oil level more frequently during engine
break-in period. If oil must be added during this period,
Northern Lights Engine Break-In Oil is preferred. See
ENGINE BREAK-IN OIL on page 14.
IMPORTANT: DO NOT use PLUS-50® Engine Oil
during the break-in period of a new engine or engine that
has had a major overhaul. PLUS-50 oil will not allow a
new or overhauled engine to properly wear during this
break-in period.
