ENGINE OIL RECOMMENDATIONS
Use of Supplemental Additives
Engine oils meeting PCM 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. PCM Engines does not review, approve or
recommend such products.
Synthetic Oils
Synthetic engine oils may be used in PCM Marine
Engines. Synthetic oils must meet the Engine Oil
Requirements for Classification 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:

IMPORTANT: The use of oils which contain "solid"
additives, non-detergent oils or low quality oils
specifically are not recommended.
WARRANTY NOTICE: PCM 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 filter change - Recommended
intervals:
• Initial oil change - 1st 60 days or 5-25 hours of
operation, whichever occurs first
• Regular oil changes - Every 50 hours of
operation or 120 days, whichever occurs first
• Heavy Duty High RPM / High Load Use - Every
30 hours of operation or 120 days, whichever
occurs first
NOTE: Never over-fill the engine with oil. Engines over-
filled with oil can cause engine damage.
