Why does an engine need oil?
Oil is used to provide lubrication between two moving parts to reduce wear. Oil is used to gather or absorb heat from the internal engine parts and carry it away. Oil is also used to flush the metal particles from the bearings of your engine. 90-95% of all mechanical engine wear occurs in the first 10 seconds of a cold engine start up. That initial cold start wear can equal hundreds of kms of warm engine wear. Using the correct oil for the season can increase the life of your engine.
