Pombi yepeturu yakakosha inonyanya kushandiswa pakuboorera mafuta negasi uye kutapurira mafuta negasi. Inosanganisira pombi yekuboorera mafuta, keji yemafuta uye pombi yekupomba mafuta. Pombi yekuboorera mafuta inoshandiswa kubatanidza kola yekuboorera nechikamu chekuboorera uye simba rekupfuudza. Keji yemafuta inonyanya kushandiswa kutsigira madziro etsime panguva yekuboorera uye mushure mekupedzwa, kuitira kuti tsime rese rishande zvakanaka uye kushanda kwakajairika mushure mekupedzwa. Pombi yekupomba inonyanya kutapurira mafuta negasi kubva pasi petsime kuenda pamusoro.

Chivharo chemafutandiyo nzira huru yekushanda kwetsime remafuta. Nekuda kwemamiriro akasiyana enzvimbo, mamiriro ekumanikidzwa kwepasi pevhu akaomarara, anodhonzwa, anodzvanywa, anokotama uye anotenderedzwa nemhepo inotsvedza papombi, izvo zvinoisa zvinodiwa zvakanyanya pamhando yebhokisi pacharo. Kana bhokisi pacharo rikakuvara nekuda kwechimwe chikonzero, tsime rese rinogona kuderedzwa kugadzirwa kana kutosiyiwa.

Zvichienderana nesimba resimbi pachayo, bhokisi rinogona kukamurwa kuita mhando dzakasiyana dzesimbi, kurevaJ55, K55, N80, L80, C90, T95, P110, Q125, V150, nezvimwewo. Mamiriro akasiyana ematsime, kudzika kwetsime, kushandiswa kwemhando yesimbi kwakasiyanawo. Chivharo pachacho chinodiwawo kuti chive nekudzivirira ngura munzvimbo inoparadza. Panzvimbo pemamiriro ezvinhu akaomarara epasi, chivharo chinodiwawo kuti chikwanise kuramba kudonha.
