ENGINE OIL RECOMMENDATIONS
Use of Supplemental Additives
Engine oils meeting Crusader Challenger 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 Challenger Engines
does not review, approve or recommend such products.
Synthetic Oils
Synthetic engine oils may be used in Crusader
Challenger Marine Engines. Synthetic oils must meet
the Engine Oil Requirements for Classication and
Viscosity listed below. The use of synthetic oil does not
permit the extension of oil change intervals.

for various ambient temperature ranges:
