An old car engine might be perfectly happy with a few good glugs of old-fashioned SAE 20W 50 viscosity mineral oil but engine technology has moved on and the demands on engine oils have moved on too with fully synthetic 5W 30 oil being the sort of thing youd use in a modern engine. How do engine oil grades work.

Engine oil viscosity grades 0w-20 0w-30 0w-40 5w 30 engine oil 5w 40 engine oil 5w-50 10w-40 engine oil grade 10w-60 15w-40.

Oils are graded according to their viscosity basically how thick or thin they are. This has led over time to motor oil viscosity decreasing currently 5W-30 and 5W-20 are the most popular grade and 0W-20 is the fastest growing grade.
