Abstract
In this study, sunflower oil at different concentrations of between 1 and 50% was added to base oil to obtain lubricating oil candidates. The lubricating oil candidates were characterised by ASTM methods, and their effects on the friction coefficient at 25 and 100°C at different speeds and loads in a statically loaded journal bearing were determined. The technological characteristics of the sunflower oil were determined according to standard methods. The study shows clear evidence that the modification of friction by sunflower oil is at least equivalent to that by mineral oil, and the lubricating oil candidates containing sunflower oil show a reduction in the coefficient of friction.
