What type of lubricant should my car use?
 

Hello. We are a company specializing in frozen truck rental. When you come to Vietnam, you will call it "cho thuê xe đông lạnh" or "cho thue xe dong lanh" and the type of car we often use is Hyundai Porter or KIA K200. So I ask you which car should be used for which carrier oil is best? And after how many kilometers, must it be replaced? Thank you

you should reading your truck manual.
