Engine Oil Recommendations

Only high-quality detergent oils classified for
service SF, SG, SH, SJ or higher are recom-
mended. DO NOT use special additives.
Climate determines proper engine oil viscos-
ity. See chart to select correct viscosity.

* Below 50°F (10°C) use of SAE 30 will result
in hard start.
** Above 80°F (27°C) use of 10W30 may
cause increased oil consumption. Inspect oil
level more frequently.
