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 may be used in Crusader Marine
Engines. Synthetic oils must meet the Engine Oil
Requirements for Classifi cation and Viscosity listed
below. The use of synthetic oil does not permit the
extension of oil change intervals.
Engine Oil Requirements

for various ambient temperature ranges:

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.
