A molybdenum-free lubricating oil composition exhibiting improved fuel economy and fuel economy retention properties, which comprises: (a) a base stock oil compound of at least 50 wt. % mineral oil, the base stock oil having a viscosity of 4.0-5.5 mm,/s at 100&deg; C., 95 wt. % or more saturates, 25 wt. % or less napthenics, a NOACK volatility of 15.9% or less, a kV of 4.0-5.5 mm,/s at 100&deg; C. and a viscosity index of at least 120; (b) at least one calcium detergent and (c) at least one organic friction modifier, wherein the composition has a NOACK volatility of about 15 wt. % or less and contains from about 0.058 to 0.58 wt. % calcium from the calcium detergent.

Molybdenum-free low volatility lubricating oil composition

A lubricating oil composition exhibiting improved low temperature anti-wear performance and improved fuel economy and fuel economy retention properties, which comprises: (a) an oil of lubricating viscosity; (b) at least one calcium detergent; (c) at least one oil soluble molybdenum compound; (d) at least one nitrogen containing friction modifier; and (e) at least one zinc dihydrocarbyldithiophosphate compound, wherein the composition has a NOACK volatility of about 15.5 wt. % or less and contains from about 0.058 to 0.58 wt. % calcium from the calcium detergent, molybdenum in an amount up to about 350 ppm from a molybdenum compound, and phosphorus in an amount up to about 0.1 wt. % from a zinc dihydrocarbyldithiophosphate compound.

Lubricating oil composition

A lubricating oil composition exhibiting improved fuel economy and wet clutch friction properties, which comprises: (a) an oil of lubricating viscosity; (b) at least one calcium or magnesium overbased detergent; (c) an oil soluble dimeric molybdenum compound; (d) an oil soluble organic trinuclear molybdenum compound; (e) at least one zinc dihydrocarbyldithiophosphate compound, wherein the composition has a TBN of at least 3.6 from the calcium or magnesium overbased detergent, a NOACK volatility of about 15 wt. % or less, molybdenum in an amount up to about 350 ppm from the trinuclear molybdenum compound, molybdenum in an amount up to 2,000 ppm from the dimeric molybdenum compound, and phosphorus in an amount up to about 0.1 wt. % from a zinc dihydrocarbyldithiophosphate compound.
