Isihluzo samafutha licandelo elibalulekileyo kwinkqubo yamafutha esithuthi. Owona msebenzi wayo uphambili kukucoca ukungcola, amanzi, kunye nesuntswana lezinto kwi-fuel, iqinisekisa isibaso esicocekileyo esingena enjinini. Oku kukhusela izinto ezibuthathaka ezifana nezitofu kunye nempompo yamafutha, kwaye bandise ubomi be-injini. Nangona kunjalo, ekuhambeni kwexesha, isihluzi sinokuvaleka kukungcola, okuchaphazela ukuhamba kakuhle kwamafutha, ukwenza ukugcinwa rhoqo kubalulekile.
Ngokubanzi, amaxesha okugcinwa kwesihluzi sepetroli axhomekeke kuhlobo lwesithuthi, indawo yokusebenza, kunye nomgangatho wamafutha. Kuninzi lweesedan zosapho, izihluzi zamafutha esintu ziyacetyiswa ukuba zitshintshwe rhoqo kwiikhilomitha ezingama-20,000 ukuya kuma-40,000, okanye qho emva kweminyaka emibini, ngokuxhomekeke kwiingcebiso zomenzi wesithuthi. Eminye imifuziselo yale mihla zisebenzisa{6}}izihluzo zamafutha obomi ezandisiweyo, kwaye amaxesha olondolozo anokwandiswa ukuya kuma-40,000 ukuya kuma-60,000 eekhilomitha, kodwa oku kufuneka kumiselwe ngokusekelwe kowona setyenziso.
Ukuba isithuthi siqhutywa rhoqo kwiimeko ezinzima (ezifana neendawo ezinothuli olunzima okanye umgangatho ophantsi we-fuel), ukuvala isihluzo se-fuel kungenzeka ngokukhawuleza. Ngoko ke, kucetyiswa ukuba ucuthe ixesha lolondolozo ukuze uhlole okanye ubuyisele isihluzo rhoqo ngeekhilomitha ezingama-10,000 ukuya kuma-20,000. Ngaphaya koko, ukuba isithuthi sakho sineempawu ezinjengokuhamba ngesantya esinamandla, ukubambezeleka kakubi, ukonyuka kokusetyenziswa kwepetroli, okanye ukuqalisa ubunzima, ezi inokuba ziimpawu zesihluzi sepetroli esivalekileyo. Kwanokuba isithuthi sakho akufuneki silungiswe rhoqo, ufanele usihlole kwangethuba.
Ukutshintsha rhoqo isihluzo samafutha akuphuculi ukusebenza kwe-injini kuphela kodwa kunciphisa umngcipheko wokusilela kwenkqubo yamafutha. Abanini beenqwelo-mafutha kufuneka bajonge incwadana yemigaqo yabanini bezithuthi zabo kwaye baqulunqe ishedyuli efanelekileyo yolondolozo esekelwe kwiimeko zabo zokuqhuba. Ukongeza, khetha -izihluzo ezikumgangatho ophezulu ukusuka kwimithombo ethembekileyo ukuqinisekisa ukuhluzwa okusebenzayo kunye nokuqina. Ukungahoyi ukugcinwa kwesihluzo samafutha kunokukhokelela kwiingxaki ezimandundu ngakumbi ze-injini kunye nokunyuka kweendleko zokuyilungisa, ngoko ke ukugcinwa rhoqo kubalulekile ukuze uqinisekise impilo-yexesha elide yesithuthi sakho.
