◆ Ngokusho kwejwayelekile ye-German API HM, ikhiqizwa ngokusebenzisa uwoyela opholile owenziwe nge-hydrogenated kanye nezithako ezisezingeni eliphezulu. ◆ Uwoyela opholile owenziwe nge-hydrogenated uhlanganiswe nezithako eziningi ezingenisiwe. ◆ Emaphutheni okuphakanyiswa, ubukhulu bamanzi uwoyela kanye nobukhulu bamanzi okuthambisa kugcinwa ukuze kuncishiswe ukugqokwa kwezingxenye ezihambayo. ◆ Ukuqina okuhle kokuphenduka kanye nokuzinza kokushisa kwemikhiqizo kawoyela kwenza kube nzima ukuwohloka ngaphansi kwezimo zokusebenza ezinzima. ◆ I-stalviscosity index iphezulu, umswakama ophansi ubuhle, ibanga lokushisa elisebenzayo libanzi. Ukuhamba kahle, ukushisa okuhle, gwema ukushisa okukhulu kwesistimu, ukushiswa kwezingxenye zemishini. ◆ Ukusebenza kokuphakanyiswa okuthuthukisiwe kuthuthukisa ukudluliswa kwamandla okuhamba kahle nokuzinzile kwesistimu ye-hydraulic. ◆ Ikhwalithi yezinto zokuvikela ukugqwala, zokuvikela ukuvuvukala nezinto zokufaka zihambisana.
