While oil life/service intervals are influenced by many factors, all Oils degrade with time and use.
In general terms the cheaper mineral based oils will degrade quicker than the more expensive Synthetic Oils.
Based on normal use, we would generally recommend the following service intervals be used as a guide to give your engine the longest life possible.
Oils are the life blood of your engine. It cools, lubricates, and cleans your engine from the inside.
With time oil doesn’t only degrade, but it also gets contaminated by fuel, dirt, fibres, and microscopic metal fragments.
Cheap oils will dump these contaminates on the walls of your engine, while expensive full Syn oils will keep these items suspended and circulating until its dumped from your engine and replaced with nice clean new oil.
