Ebola -I admire your iconoclastic tendencies, but must take issue with a few points:
The days when cars lasted 50,000 - 100,000 miles ended with point ignition and twice-a-year tune-ups. Modern vehicles are just getting broken in at 100K.
Lubes are not why oil prices and supply are volatile. A 42-gallon barrel of crude typically produces about a quart of lube basestock. One of the best arguments in favor of moving away from petroleum-based fuels is to save those molecules for lubes & chemical products. A typical barrel of crude is 20% 'natural gasoline', but we tweak another 30+% into fuels. It's an amazingly valuable mineral that has a finite (if unknown) supply remaining and we're burning it for fuel? If passenger car fuels moved away from petroleum, refinery engineers would just twiddle the dials (and modify units during turnaround) to align the product mix with demand.
Otherwise, nicely done.
