Qhov tseeb paub zoo yog tias viscosity hloov nrog kub. Synthetic multigrade roj 20 wb 40 Yeej willthin tawm ntau ntawm qhov kub thiab txias tshaj qhov 20 w50 roj (tshwj tsis yog ntawm 40 degree C).

Ntawm no, kuv tuaj yeem siv 20w40 tsis yog 20w50?

20w50 ua tuav ntawm viscosity marginally zoo dua 20 wb 40 thaum lub cav kub. Txawm li cas los xij, 20 w50 ntxhia roj yuav ua rau sludge ntau tshaj li qhov sib xws 20 wb 40 vim 20w50 ua muaj ntau viscosityimprovers. Pulsar 150's phau ntawv qhia pom zoo 20 wb 40 , mas koj siv tau los yog, tsis muaj ntau qhov sib txawv.

Tsis tas li ntawd, qhov twg yog qhov zoo dua 10w30 lossis 20w40? 20 wb 40 yog thicker ntawm qhov kub thiab txias (normaloperating condition of engine) piv rau 10 w30 . Rau properlubrication ntawm kev khiav hauj lwm kub siab viscosity yog ntshaw. So 20 wb 40 yuav zoo piv rau 10 w30 ntawm normaloperating tej yam kev mob. Thiab ntawm qhov kub thiab txias 20 wb 40 isthicker li piv rau 10 w30.

Ntawm no, qhov twg zoo dua 10w40 lossis 20w50?
