The results of testing the tribological characteristics of biodegradable repeceed-based hydraulic/transmission oils showed, that they exibit better or even similar mechanical properties, but worse oxidative stability compared with a corresponding mineral-based oil. The hydraulic/transmission rapeseed-based oils with their native properties and additives have similar lubrication properties as lubricants based on mineral oils, but they are in addition biodegradable and non-toxic"},{"@xml:lang":"sl","#text":"V prispevku smo predstavili fizikalno-kemijske lastnosti olj na osnovi oljne repice (oljne ogrščice) pred in med mehanskimi preskusi in po njih.
