Pulogalamu yapadera yama petroleum imagwiritsidwa ntchito kwambiri mafuta ndi mpweya wobowola ndi kufalikira kwa mafuta ndi mafuta. Zimaphatikizaponso mafuta obowola obowola, mafuta a mafuta ndi chitoliro chopopera. Chitoliro chobowola chimagwiritsidwa ntchito kulumikiza kolala yobowola mpaka kubowola pang'ono ndikusamutsa mphamvu yobowola. Kugwira mafuta kumagwiritsidwa ntchito makamaka kuthandizira pa khomalo mukamabowola ndipo mukamaliza, kuti atsimikizire kuti kubowola kwathunthu ndi kuchita bwino. Chitoliro chopondaponda chimasamutsa mafuta ndi mpweya kuchokera pansi pa chitsime pansi.

Mafuta a mafutandi njira yamoyo wamafuta. Chifukwa cha mikhalidwe yosiyanasiyana ya zigawo, kupsinjika mobisa ndizovuta, tuensile, kupsinjika, kuwerama komanso kupsinjika kwamphamvu kumagwira ntchito pathupi, komwe kumayambitsa zofunikira zapamwamba pazokha. Ngati kudzipatula kwawonongeka pazifukwa zina, chitsime chonse chitha kuchepetsedwa kapena kusiyidwa.

Malinga ndi mphamvu ya chitsulo chokha, kasombayo imatha kugawidwa m'magulu osokoneza bongo osiyanasiyana,J55, K55, N80, L80, C90, T95, P110, q125, v150, v150, ndi zina zokwanira, kuzama, kugwiritsa ntchito kalasi yachitsulo ndikosiyananso. Chodzichotsera chokha chimafunikiranso kukana kuwonongeka kwa malo okhalamo. M'malo mwa zovuta zamiziro, kusamalira kumafunikiranso kuti kuthetsedwe.
