The more I read about oil on here, honestly the more questions I have.
Instead of so many types, weights, etc.
Why not just sell full synthetic 0W40 for all cars?
Synthetic seems superior to dino, or semi synthetic.
But especially the weight aka thickness of the oils.
Just having 0W40 should cover everything correct?
Easy cold weather starts, good protection when hot i assume?
Am I over simplifying this?
Or should I just buy 0w40 for everything, and simplify my life.
