If anything if one takes the data from today's engines they make more power than ever and last longer than ever before. Even when compared to the thick oil days.
And today's 20 grades at 100 times better than anything ever before,
Well, I would not put all the credit into the advancement of oil technology.
The internal engine design changed quite drastically since early 2000's. If you look at the block and how the mains are supported, most econoboxes today are built like sport's car engines of 80's and 90's. They are quite stiff with little crank flex.
These things were done in co-operation. Oil development alone would've never succeeded without changes in engine design.
