Abstract:
The present invention provides a mineral base oil having a kinetic viscosity at 100° C. of 7 mm 2 /s or more and less than 10 mm 2 /s, a viscosity index of 100 or more, and a temperature gradient Δ|η*| complex viscosity between two temperature points of −5° C. and −15° C. of 240 mPa·s/° C. or less as measured with a rotary rheometer at an angular velocity of 6.3 rad/s. The use of the mineral base oil enables easy preparation of a lubricating oil composition and a grease composition having excellent oxidation stability while ensuring the freedom of selection of additives.

Claim (Index 11):
The grease composition according to  claim 10 , wherein the thickener is one or more selected from a metal soap and a urea compound.
