The present invention provides an ashless lubricating oil composition that improves the corrosion properties in natural gas engines. The ashless lubricating oil composition comprises:

Ashless lubricating oil formulation for natural gas engines

The use of an effective amount of a compound as an additive improving the compatibility of a lubricating oil formulation having dispersants containing basic nitrogen atoms, with fluorocarbon elastomer seals. That compound has the formula: ##STR1## wherein R and R.sup.1 are independently alkoxycarbonyl, alkenyloxycarbonyl, aryloxycarbonyl, alkylcarbonyl, alkenylcarbonyl, arylcarbonyl, or arylalkyl, or together form a carbocycle, and R.sup.2 and R.sup.3 are independently sulfurized alkyl, alkoxycarbonylalkyl, arylalkyl, or borated hydroxyalkyl, with the proviso that R, R.sup.1, R.sup.2 and R.sup.3 together contain sufficient carbon atoms to render the compound oil soluble in an oil of lubricating viscosity.

Fluorocarbon elastomer compatibility improving agent having wear

Oil soluble compounds having the formula: ##STR1## wherein R and R.sup.1 are independently cyano, alkoxycarbonyl, aryloxycarbonyl, alkenyloxycarbonyl, alkylcarbonyl, arylcarbonyl, alkenylcarbonyl, alkylsulfonyl, arylsulfonyl, alkenylsulfonyl, substituted aminocarbonyl, alkylphosphoryl, arylphosphoryl, alkenylphosphoryl, aryl, or heterocyclics, or together form a carbocycle or heterocycle, and R.sup.2 and R.sup.3 are independently alkyl, alkenyl, hydroxyalkyl, sulfurized alkyl, alkoxycarbonylalkyl, arylalkyl, or borated hydroxyalkyl, with the proviso that R, R.sup.1, R.sup.2 and R.sup.3 together contain sufficient carbon atoms to render the compound oil soluble in an oil of lubricating viscosity. The compound are useful as wear protectants or extreme pressure agents to enhance wear protection or extreme pressure properties in lubricating oils and greases.

Bis(thio)ethylene ashless wear inhibitors and lubricating oils and

Oil soluble compounds having the formula: ##STR1## wherein R and R.sup.1 are independently cyano, alkoxycarbonyl or together form a carbocycle or alkylcarbocycle and R.sup.2 and R.sup.3 are independently alkyl, alkenyl, hydroxyalkyl sulfurized alkyl, or alkoxycarbonylalkyl. The compound are useful as wear protectants or extreme pressure agents to enhance wear protection or extreme pressure properties in lubricating oils and greases.
