Abstract
Diesters of dodecanedioic acid (DDDA) have been found to exhibit frictional,antiwear and viscosity-temperature properties which are superior to those of other dibasic acid esters, synthetic hydrocarbons and petroleum oils. A OW-30 part synthetic motor oil which contained 43% di(isooctyl)dodecanedioate (DIOD) readily passed IIID, V-D and L-38 sequence engine tests. This oil also showed a 4.7% fuel economy benefit versus an SAE-30 oil when tested in a diesel-powered automobile.
Laboratory bench wear test data suggested that DIOD could be useful as a low level (5–10%) blending component in automotive lubricants, It not only brings about friction and wear reductions when added to petroleum oils but also leads to reductions when added to other synthetic base oils such as adipate diesters and polyalphaolefins.
