This paper presents the results of comparative investigations on the lubricity and energetic superficial properties of selected petroleum products and new ionic liquids (ILs). Three base oils from polish petroleum refinery (PAO—6, SN-650, SN—350) and lubricity additive (Additin RC2515 EP) have been investigated comparatively to four ionic liquids with imidazolium organic cations and different inorganic anions, i. e. bis (trifluoromethylsulfonyl) imide and tetrafluoroborate. The lubricating ability properties petroleum products and ionic liquids have been assessed according to Polish Standard PN-76/C-04 1 47 (ASTMD2596-69 and ASTM D2270-77) on Four-Ball Testing machine. The investigation range of lubricity properties are limited to the assessment only two parameters i. e. P(t) - seizure load for increasing continuous loading and G(oz) - wear limiting load capacity. The superficial properties of oil compounds and ionic liquids have been assessed by means of modern KSV Sigma 701 Tensiometer. Surface tension o and wetting angle fi were assessed. The obtained results confirmed the possibilities of using tested ionic liquids as lubricants. The best lubricity properties, close to properties of Additin RC2515, had 1—methyl— 3—oktyloxymethylimidazolium tetrafluoroborate.
