From PCM:

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 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”
Below 50˚F SAE 5W-30 “GF-4/SM”

IMPORTANT: The use of oils which contain “solid”
additives, non-detergent oils or low quality oils
specifi cally are not recommended

I probably would have gone with a 40 weight like the manual says but then I saw what Tige said. I then checked with the dealer. And all the different opinions on here.

who's going home

[thtrog]

I run 15w-40 in mine

[thtrog]

change every 50 hours

Indmar says no synthetic until after 100 hours

I'm pretty sure my dealer uses a syn blend

One thing I found interesting is that the engine is a 2007 and the manual states it needs to be SF or SG complient. I have only seen SF on one oil and that was a Penzoil Plat. Synthetic 5W-30. So I decided to look up SF and SG. They are 1980 - 1990 oil standards. A little old.

I use 15w-40 in my diesel. I went to synthetic and could only find 5w-40. Rotella

I am over that. One obstacle done.

change every 50 hours

I am hoping to get 50 hours plus this year.
