Out west we define a "mountain" as a piece of rock on which there is a tree line, anbove which no vegetation grows and which is permanently snow covered for the upper 10 percent or so. Anything with vegetation all the way to the top is a "hill".
I've heard that those CAT diesela can take that kind of treatment day after day and still go 250K miles between maintenance stops. I wish my V-10 could do that! It's more likely to die of neglect, with only 18,000 miles since 2002 and only 5K since we bought it 4 years ago!
After my family owned one of the early Austim/Morris Minis in tne UK (1959), I was amazed by how long-lived US automobile engines were. The Mini needed three replacement transmissions and two replacement engines in the first 40,000 miles. It had rusted to a perforated shell by then anyway, so we junked it.
