ENGINE OIL RECOMMENDATIONS
Use of Supplemental Additives
Engine oils meeting Crusader Marine Engines’
recommendations already contain a balanced additive
treatment. The use of supplemental additives which are
added to the engine oil by the customer are unnecessary
and may be harmful. Crusader Marine Engines does not
review, approve or recommend such products.
Synthetic Oils
Synthetic engine oils are not recommended for use
in Crusader Marine Engines. Synthetics may offer
advantages in cold temperature pumpability and high
temperature oxidation-resistance. However, synthetic
oils have not proven to provide operational or economic
benefi ts over conventional petroleum-based oils in
Crusader Marine Engines. Their use does not permit the
extension of oil change intervals.
Engine Oil Requirements
The following chart shows the recommended oil viscosity
for various ambient temperature ranges:
Prevailing Ambient Recommended A.P.I.
Temperature Classifi cation & Viscosity
Above 50˚F SAE 15W-40 “SM”
Below 50˚F SAE 5W-30 “SM”
IMPORTANT: The use of oils which contain “solid”
additives, non-detergent oils or low quality oils
specifi cally are not recommended.
WARRANTY NOTICE: Crusader Marine Engines
reserves the right to refuse warranty on part(s) and/or
engine(s) damaged by using improper fuels and engine
oils.
Oil Change Intervals (Common)
Crankcase oil and oil fi lter change - Recommended
intervals:
• Initial oil change - 1st 60 days or 25 hours of
operation, whichever occurs fi rst
• Regular oil changes - Every 50 hours of
operation or 120 days, whichever occurs fi rst
TRANSMISSION AND “V”-DRIVE OIL
REQUIREMENTS
NOTICE: WALTERS “V”-DRIVES ONLY - A low oil
pressure warning light is mounted on Walters “V”-Drives.
The warning light will stay illuminated until the boat gets
underway, and the engine speed increases to suffi cient
RPM for the pump to maintain pressure. This normally
occurs at approximately 1200 RPM. Extended cruising
at low RPM, such as when trolling, is not harmful to
the “V”-drive, even though the warning light may remain
illuminated.
