Yah, it's interesting. One of my hobbies, long ago in the 1970s to 1990s, was restoring classic T-Birds (1955-57). When these were new in the mid-50s, the engines would be pretty much worn out at 100K miles, tired and smelly and smoky. In the 1990s, with modern lubricants, the very same engines would easily go twice that distance, and they would still be quiet and clean and the cylinders would still look good when I tore them down. I drove the heck out of'em, too.
Some things have got better through the decades. Now if they would only come up with better lubricants for me ... but it's too late, I'm already tired and smelly, though of course not smoky.
