Inzobere mu kinyamakuru cyo mu kinyamakuru cy'Uburusiya cyasobanuwe inshuro zi ngombwa guhindura amavuta muri moteri.
Icyiciro cya "WG" cyibukije ko gukora imyitozo isaba guhindura amavuta hafi ya buri 15,000 km cyangwa rimwe mu mwaka. Ariko, birakenewe kuzirikana imiterere yimikorere ya mashini, leta ya moteri, kimwe nubwoko bwamavuta. Niba imodoka ikoreshwa cyane, nibyiza guhindura amavuta mbere gato. Igikorwa muri "Tagisi" bisobanura ingendo zigihe gito hanyuma ukore kuri ubusa mugihe utegereje abakiriya. Akenshi, imodoka nkiyi irashobora gukora hafi yikirundo iminsi irindwi mucyumweru. Hamwe niki kibazo, ubuzima bwa peteroli buragabanuka bwa gatatu, kandi niba bishoboka - kabiri.
Gutekereza kubiciro byo gusimbuza peteroli bikunze kubamo abamotari bakoresha imodoka zabo mu turere twamajyaruguru kandi bahora bahura nazo "imbogamizi" mugihe moteri ya dogere -15 kandi hepfo. Ibi ni ukuri cyane cyane ku mashini zikoreshwa mucyaro cyangwa ahantu h'imisozi. Muyandi magambo, mugihe ukoresheje imashini munsi yumutwaro cyangwa hamwe no kugendana, amavuta ya moteri atakaza imiterere yingirakamaro vuba.
Bizirikana nabi imiterere yamavuta nigice cyamashanyarazi birashobora kugenda, akenshi zikora imyaka yashingira. Niba utwaye intera ngufi udahaye moteri kugirango utezimbere umuvuduko mwinshi, noneho amavuta ntashobora kugera kubushyuhe bwagaciro, bitewe nimitungo yacyo izacibwa igihe. Ku muvuduko muto, moteri iri munsi yiyongereye kuberako idahagije yo gusiga ibintu. Byongeye kandi, moteri ntabwo ari moteri ihagije kuri moteri. Kubera iyo mpamvu, igituba cy'ivangura ry'ikirere kibaye, wambara imyenda ya Crankshaft imburanda n'itsinda rya piston, imyitozo ya peteroli, izokoresha ya peteroli irakajwe kandi, amaherezo, itesha agaciro amavuta yihuta.
Impuguke zibutsa ko ari ngombwa kugenzura buri gihe urwego rwa peteroli, kuko niba urwego ruri kuri kimenyetso gito cyangwa byibuze, igice cyo hasi, icya mbere, gitangira kubabazwa n'amavuta ya peteroli, kandi, icya kabiri, imitungo yakazi ya lubricant yagabanutse. Niba udahinduye amavuta ya kilometero 25.000 - 30.000, biba umubyimba, bitangira gusiga ibintu byimuka kandi utange imiyoboro ya moteri, ishobora "kwica" moteri yimodoka.
