OIL REQUIREMENTS

ENGINE OIL RECOMMENDATIONS

Use of Supplemental Additives

Engine oils meeting Crusader 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 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

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 “GF-4/SM”
