Indmar Marine Engines
6-5
Do not overfill. If your oil level is above the
full mark on the dipstick, the engine may be
damaged.
Indmar uses and recommends Pennzoil Marine 15W-40
Marine Oil API Service SL/SJ/CI-4, CH-4, CG-4 or
equivalent. If engine is to be used on conditions below
20° F (-7˚ C), use Pennzoil Marine SAE 10W-30 API
Service SL/SJ/CI-4, CH-4, CG-4 or equivalent.
The use of engine oil other than 15W-40 with
an API SJ/CG4 designation can cause engine
damage. Damage to your engine caused by
the use of improper oils is not covered by
your warranty.
Synthetic Oil
Synthetic oil that meets our requirements of 15W40 and
API SL/SJ/CI-4, CH-4, CG-4 is acceptable to use after
100 hours of operation with the recommended oil. The
use of synthetic oil does not change the requirement of
50 hour oil change intervals.
Changing Oil
Change your engine oil after the first 10-20 hours of
operation. Then change oil every 50 hours or annually,
whichever comes first. To maximize engine life, change
the oil filter at every oil change.
Figure 6.4 – Oil Filter
Indmar recommends all engine maintenance procedures
be performed by your dealer, including oil changes. If you
must perform the oil change yourself, operate the engine
to full operating temperature.
