Uma ithangi likaphethiloli lemoto yami lilingana namalitha angu-18, kukangaki ngidinga ukugcwalisa uphethiloli ohambweni lwamahora angu-10 uma isivinini esijwayelekile singu-60mph futhi ukusebenza kahle kukaphethiloli kwemoto kungu-30mpg?
Uma ucabanga ukuthi ithangi ligcwele lapho uqala, kuyodingeka ugcwalise ithangi kanye. Amahora ayishumi ngesivinini esingamakhilomitha angu-60 ngehora kusho ukuthi ibanga lilonke lingamamayela angu-600. Ukuze ushayele amamayela angu-1600 ngophahla lwamafutha olungu-30 mpg udinga amalitha angu-20 kaphethiloli. Lokho kungaphezu kwamagaloni angu-18 okuqukethwe yitanki, kodwa kungaphansi kokuphindwe kabili, ngakho-ke kuyodingeka ugcwalise uphethiloli kanye.
