CAUTION
Do not switch oil brands indiscriminately because some
oils interact chemically when mixed. Use of inferior oils
or non-detergent oils can damage the engine.

Oil level should be between lower and upper dipstick
level marks. If oil level in tank is below lower mark of dip-
stick, add oil to tank. Install filler cap/dipstick.
Recommended viscosity depends upon ambient temper-
ature. See 
 
NOTE
Difference between upper and lower dipstick marks is
0.5 quart (0.47 liter).
