Indmar Marine Engines xi
Lubricant – Indmar uses and recommends
Pennzoil 15W40 Marine Oil for use in all of its
engines except for the 8.1 liter models which use
Pennzoil 40W oil. If Pennzoil Marine oil is not
available, any appropriate viscosity motor oil
meeting the API ratings of SL/SJ, CI-4, CH-4,
CG-4 is acceptable. See Chapter 6, Maintenance,
for information regarding the use of synthetic oil.
Additives – The only additive that is recommended
by Indmar for use in your engine is Sta-Bil brand fuel
stabilizer. This additive helps preserve the fuel in your
tank and in the engine’s fuel system. We recommend
the use of Sta-Bil during off-season storage and for
the boater that consumes less than a full tank of fuel
every two weeks. See Chapter 5, Fuel, for more infor-
mation.
