Over the last 30 years or so, motor oils have improved substantially and so have the engines they go in. But could you definitively say one has improved much faster than the other? I’d lean towards oils, but it’s nothing more than a hunch.

Was just looking at an ad for a 1985 Caddy and it got me thinking about what the ceiling would be for an engine of that era if a guy bought it and fed it today’s best oils.
