◆ Ngokuhambisana ne-API VG yekhwalithi yeJalimane, ikhiqizwa ngokusebenzisa uwoyela obhakiwe ophumile kanye nezithasiselo ezisezingeni. ◆ Uwoyela obhakiwe ophumelelayo uhlanganiswe nezithasiselo ezihlukahlukene eziphumile. ◆ Emaphuzwini okuphazamiseka, ubukhulu bokuhluza uwoyela kanye nobukhulu bawo bokuhluza buphathelene ukuze kuncishiswe ukugqokwa kwezingxenye ezihambayo. ◆ Ukuqina okuhle kokuphenduka kanye nokuzinza kokushisa kwemikhiqizo kawoyela kwenza kube nzima ukuphuka ngaphansi kwezimo zokusebenza ezinzima. ◆ I-stalviscosity index iphezulu, uketshezi lokushisa okuphansi luhle, ibanga lokushisa elisebenzayo libanzi. Ukuhamba kahle, ukushisa okuhle, gwema ukushisa okukhulu kwesistimu, ukugqokwa kwezingxenye zomshini. ◆ Ukusebenza kahle kokuphakela kuthuthukisa ukudluliswa kwamandla okuhamba kahle nokuzinzile kwesistimu ye-hydraulic. ◆ Ikhwalithi yezinto zokuvikela ukugqwala, zokuvikela ukwakheka kweqhwa nezinto zokufaka zihambisana.
