4.0 Engine Oil Recommendations
Oil affects performance and service life for the engine. Always use 4-stroke automotive detergent oil. The engine
can hold .58 U.S. qt (.55 L) of oil.
SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average
temperature in your area is with the recommended range (see Figure 4-1).

The SAE oil viscosity and service category are in the API label on the oil container. We recommend that you use
API SERVICE category SJ or later (or equivalent) oil.
CAUTION!
Hot engine oil can BURN. The engine should be warm to the touch but not hot when changing the oil.
Draining warm oil assists rapid and complete draining.
