How much oil and viscocity type is needed for a regular/routine oil change in a temperate region like Nigeria? Mechanics say just one gal. Is ok? I change my oil quarterly with a gal. Of 20w-50 type, I have not really noticed any strangeness but I'd like to know the exact qty and type to use. How often do I change my oil considering my region?
