Ukuba ubonelelo lwepetroli nganye lwesilili sedizili alulingani (umzekelo, ukubonelelwa kweesilinda ezithile kukhulu kakhulu, kunye nokuhanjiswa kwamafutha kwezinye iisilinda zincinci kakhulu), kuya kuchaphazela ngokuthe ngqo uzinzo lomvelisi wedizili. Impompo yenaliti ingasuswa ukuze ihlolwe kwaye ilungelelaniswe kwibhentshi yovavanyo. Nangona kunjalo, ukuba akukho bhentshi yovavanyo kwaye ukuhlolwa kokunikezelwa kwamafutha okungalinganiyo kuyafuneka, ukuvavanywa okurhabaxa konikezelo lwamafutha lwesilinda esikrokrelwayo nako kunokwenziwa kwisithuthi.

Ukuhlolwa kunye nohlengahlengiso lwendlela yokuhambisa amafutha ngokungalingani:
Lungiselela iisilinda ezimbini zokulinganisa iglasi ukuze zisetyenziswe kamva. Ukuba awufumani silinda sokulinganisa okwethutyana, unokusebenzisa iibhotile ezimbini ezifanayo endaweni yoko.
EmSusa umbhobho weoyile oxinizelelo oluphezulu oludibanisa inaliti yombane kwisilinda ngokuhambisa kakhulu (okanye kuncinci kakhulu).
EmSusa umbhobho oxineneyo oxineneyo odibanisa inaliti yombane kwisilinda kunye nesiqhelo sonikezelo lwamafutha.
Fakela iziphelo zemibhobho yeoyile ibe zizilinda ezimbini zokulinganisa (okanye iibhotile) ngokwahlukeneyo.
Sebenzisa i-starter kunye nejenereyitha ukujikeleza impompo yenaliti yokumpompa ioyile.
Xa kukho isixa esithile sedizili kwisilinda (okanye igutyana), beka isilinda kwiqonga lamanzi kwaye uthelekise isixa seoyile ukumisela ukuba ingaba umbane mkhulu kakhulu okanye mncinci kakhulu. Ukuba kusetyenziswa ibhotile endaweni yayo, inokulinganiswa ithelekiswe.
