Other high-quality detergent oils are acceptable if classified
for service SF, SG, SH, SJ or higher. DO NOT use special
additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
* Above 80°F (27°C) the use of 10W30 may cause
increased oil consumption. Check oil level more
frequently.
Checking Oil Level.
