will vary when using different oil weights. Consult the engine manufacturerís manual
for other variables.
FOR ENGINES EQUIPPED WITH OPTIONAL COLD STARTING AID
The engine is equipped with a grid heater inside the induction manifold. If the

ignition switch to START until the air-intake heater light goes OFF.
At temperatures below 10 F (-12 C), operate the engine at moderate speeds for 5
minutes before full loads are applied.
