Abstract
Friction of internal combustion engines is reduced by adding a minor amount of a friction-reducing additive to the lubricating oil or fuel used in such engines. The additive is an aliphatic hydrocarbyl sulfinyl or sulfonyl methane. Performance is enhanced by including a di-lower alkyl C.sub.12-36 aliphatic hydrocarbyl phosphonate.
