Yeah, with 2000 mile oil changes!
And a "long way" for an air cooled VW was 75K miles.
I rebuilt hundreds of them in the '70s and early '80s. I didn't really make too much note at the time, because it was normal for the situation, but when you tore them down, the bearings were always nasty... embedded with lots of junk and badly worn. The VW engines that lived the longest lives were well maintained ones that didn't drive long distances and lived in a cool climate.
