Use straight mineral oil SAE-90 for
temperature -18 degrees C (O degrees F) and up.
Use
SAE-80 for temperatures below -18 degrees C (O
degrees F).
SPECIAL RECOMMENDATIONS:
Where
temperature is consistently below -18 degrees C (O
degrees F) and where parked vehicles are exposed to
unusual cold for long periods, use SAE-75.
Where
temperatures are consistently above 32 degrees C (90
degrees F) or unusually hot, use SAE-140 straight
mineral oil.
