Engine Oil
To help obtain optimum engine performance and to provide maximum protection, we
strongly recommend the use of MerCruiser 4-cycle 25W40 Engine Oil. This oil is a special
blend of 25-weight and 40-weight oils for marine engines. If not available, a good grade,
straight weight, detergent automotive oil of correct viscosity, with an API classification of SJ,
CF-2, CH-4 may be used.
In those areas where MerCruiser 4-cycle 25W40 Engine Oil or a recommended straight
weight oil are not available, a multi-viscosity 20W40 or, a less preferable choice, 20W50,
with API service ratings of SJ, CF-2, CH-4 may be used.
IMPORTANT: The use of non-detergent oils, multi-viscosity oils (other than
MerCruiser 4-cycle 25W40 Engine Oil or a good quality 20W40 or 20W50), synthetic
oils, low quality oils or oils that contain solid additives are specifically not
recommended.
The chart below is a guide to engine oil selection.
