The influence of energy-saving engine oil additives on the parameters of the internal combustion engine has been studied. The tests were carried out on a stand with a 4-stroke gasoline engine. The additives contained a pentaerythritol ester and a complex compound of copper or molybdenum. It is shown that the introduction of additives in motor oils SAE 10W40, SAE 30 reduces fuel consumption, reduces the content of CO and CH in the exhaust gases. The resulting effect is explained by the formation on the conjugate surfaces of a tribopolymer antifriction film, which reduces the gap between the piston and the cylinder. This leads to an increase in compression and a more complete combustion of fuel.
