Amalebula kawoyela. Iluphi ulwazi olubaluleke kakhulu?
Nakuba izimpawu ezikumalebula kawoyela wenjini zingase zibonakale ziyinkimbinkimbi, akunzima ukuziqonda. Udinga nje ukukwazi ukuzifunda.
Ipharamitha yokuqala okufanele uyinake yi-viscosity. Uma incane, inciphisa uwoyela nokumelana nenjini ngesikhathi iqala nokusebenza. Amafutha enjini ane-viscosity ephansi aqokiwe: 0W-30, 5W-30, 0W-40 futhi anezindawo zokuvikela ezihlukile emazingeni okushisa aphansi. I-5W-40 iwukuvumelana, i.e. amafutha e-viscosity aphakathi. I-10W-40, 15W-40 isho i-viscosity ephakeme kanye nokumelana nokugoqa okwengeziwe. I-20W-50 ine-viscosity ephezulu kakhulu nokumelana nokugijima okuphezulu, kanye nokuvikelwa kwenjini okungcono emazingeni okushisa aphezulu.
Enye into izinga lamafutha. Amakilasi ekhwalithi angachazwa ngokuhambisana namazinga e-ACEA (European Vehicle Manufacturers Association) noma i-API (American Petroleum Institute). Owoyela bahlukaniselwe kulawo ahloselwe izinjini zikaphethiloli (uhlamvu A), izinjini zikadizili (uhlamvu B) nezinjini zikaphethiloli ezinezinhlelo ze-catalytic, kanye nezinjini zikadizili ezinezihlungi ze-DPF (uhlamvu C). Incwadi ilandelwa inombolo ebangeni le-1-5 (yekilasi C kusukela ku-1 kuya ku-4), lawa makilasi ahlinzeka ngolwazi ngemingcele ehlukahlukene yokuvikela ukugqoka, kanye nokuphikiswa kwamafutha kwangaphakathi, okuthinta ngokuqondile ukusetshenziswa kukaphethiloli.
Endabeni yamabanga ekhwalithi ye-API, amafutha enjini kaphethiloli abonakala ngohlamvu S olulandelwa uhlamvu lwezinhlamvu, olufana no-SJ (uma uhlamvu luqhubeka, izinga likawoyela liya phezulu). Ngokufana namafutha enjini kadizili, ukuqanjwa kwawo kuqala ngohlamvu C futhi kugcine ngolunye uhlamvu, njenge-CG. Kuze kube manje, amakilasi aphakeme kakhulu e-API yi-SN ne-CJ-4.

Abakhiqizi bezimoto abaningi bethula izindinganiso zabo ezisekelwe ekuhlolweni kwe-dyno injini kanye nokuhlolwa komgwaqo. Lezi zinhlobo zamazinga yiVolkswagen, MAN, Renault noma iScania. Uma ukugunyazwa komkhiqizi kusephaketheni, khona-ke uwoyela uphumelele izivivinyo eziqinile zokuqinisekisa izakhiwo zawo.
Iphakheji ingase futhi ibe nolwazi mayelana nezincomo zomenzi. UCastrol useneminyaka usebenzisana nabakhiqizi bezimoto kanti kungamafutha alolu hlobo anconyelwa izinjini zezimoto ezifana neBMW, Ford, Seat, Volvo, Volkswagen, Audi, Honda noma Jaguar, ezingatholakali emafutheni kuphela. ukupakishwa, kodwa futhi ku-cap yokugcwalisa uwoyela kulezi zimoto.
