Handling Engine Oil
1. When handling and storing engine oil,
be careful not to allow dust and water to
contaminate the oil. Clean around the
filler port before filling.
2. Do not mix lube oils of different types or
brands. Mixing may cause the chemical
characteristics of the oil to change and
lubricating performance to decrease,
reducing the engine’s life.
3. Engine oil should be replaced at the
specified intervals, regardless if the
engine has been operated.
Engine Oil Viscosity
SAE 10W-30 or SAE 15W-40 are the
recommended oil viscosities.
If you operate your equipment at
temperatures outside the limits shown,
consult your authorized YANMAR dealer or
distributor for special lubricants or starting
aids.
