Wasu ƙasashe suna da wahala sosai don gwada ingancin mai ta kayan aiki, muna ɗaukar hanya mai sauƙi don gwada ingancin mai, domin sanar da ku game da ingancin mai.
A yau muna ɗaukar bidiyon game da gwajin ingancin man shafawa, zaku iya bincika ingancin samfuran ku kuma kwatanta tare da mu!
Kyakkyawan maiko bayan konewa, komai lubricity, mannewa da shear har yanzu suna da ƙarfi sosai, kuma suna kare ɗaukar nauyi.
Mun yi shi.
