I agree 100%.
I recently had a conversation with a fellow running a fleet of trucks
hauling St Augustine grass all over the country.
I said "Cars engines last longer because of cleaner fuels and lower
compression, and most of the Chevys, Ford trucks were still using the big
engine bearings that were designed to handle the high compression and
high octane fuels of the middle fifties."
He said, like you; its was mostly improved motor oils, but the "smaller
engines turned more RPMs and tend to run hotter so better oil wasn't an
option".

By the way ...... what ever happened to the ceramic coated pistons and
cylinder heads that were supposed to be coming in new cars five years
ago?
