Current ambient and technological demands on automotive emissions and oil consumption motivate the development of basic lubricant oils of high thermal and chemical stability and use of highly specified additives. This work evaluates some types of friction modifier additives present in spark ignition and compression ignition engine oils, using a four-balls measuring device. The tribology of conventional lubricating oils were evaluated and compared to those of lubricating oils with friction modifier agents. The test results allowed for determination of the effects of utilization of friction modifiers in automotive lubricating oils.
