Chris, I don't know if we have any better fuel here in Europe
But cars are incredible expensive here compared to USA
So i think we take better care of them, oilchanges and
so on.
In the 80s-90s i tore down a lot of engines that was run
in USA and everyone was so full of grime so i suspect they
changed the oil every solareclipse

Liftervalleys so full of coxed oil so there was just holes for the
pushrods. You never se that on a engine that was run i Sweden
One 460 had kind of a rubber/plastic drain plug and six of them
in the pan. They had just pushed in the old one when they drained
the oil, so six oil changes at least
