Nthawi ya alumali ya zosefera zamafuta nthawi zambiri imakhala chaka chimodzi kapena ziwiri, zomwe zimagwiritsidwa ntchito pazosefera zamafuta zosagwiritsidwa ntchito kapena zosaphatikizidwa. Akangoyikidwa ndikugwira ntchito, moyo wake weniweni wautumiki udzakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo khalidwe la mafuta, malo ogwirira ntchito, ndi machitidwe oyendetsa galimoto. Ntchito yayikulu ya fyuluta yamafuta ndikusefa zinyalala, ma colloid, ndi madzi kuchokera mumafuta a injini kuti zitsimikizire ukhondo wamafuta, potero zimapatsa mphamvu komanso chitetezo cha injini. Ngakhale fyuluta yamafuta ndi gawo lowopsa la injini yamagalimoto ndipo imafuna kusinthidwa pafupipafupi, moyo wake wa alumali sutsogolera mwachindunji kulephera kwa zosefera chifukwa cha kutha. Kuti injini isagwire bwino ntchito ndikukulitsa moyo wake, tikulimbikitsidwa kuti musinthe fyuluta yamafuta pafupipafupi malinga ndi malangizo a wopanga ndi kukonza. Pansi pa malo osungira bwino, fyuluta yamafuta yosatsegulidwa imatha kukhala ndi nthawi yayitali. Komabe, ikangogwira ntchito, moyo wake wa alumali udzakhudzidwa ndi malo enieni ogwirira ntchito ndi momwe zinthu zilili. Chifukwa chake, kuyang'anira nthawi zonse ndikusintha fyuluta yamafuta ndi njira yofunika kwambiri kuti galimoto isayende bwino.
