FUEL AND OIL
Gasoline Recommendation
Johnson highly recommends that you use alcohol-free
unleaded gasoline with a minimum pump octane rating of 87
(R+M / 2 method) or 91 (Research method). However,
blends of unleaded gasoline and alcohol with equivalent
octane content may be used.
Allowable maximum blend of a single additive (not combina-
tion):
5% Methanol, 10% Ethanol, 15% MTBE
If leaded gasoline is used, engine damage may result.
Use only unleaded gasoline.
Engine Oil
Use only Evinrude/Johnson Ultra™ Four Stroke Oil or oils
that are rated SE, SF, SG, SH, or SJ under the API (Ameri-
can Petroleum Institute) classification system.
The viscosity rating should be SAE 10W-40.
If an SAE 10W-40 motor oil is not available, select an alter-
native according to the chart at right.
BREAK-IN (First 10 Hours)
Use only Evinrude/Johnson Four Stroke Oil or SAE 10W-40,
