IC engines are far from infinite. In fact, most can "only" burn in the neighborhood of 3-5K gallons of fuel per cylinder before requiring a major overhaul.

It's admittedly quite a bit more than the supercharger equivalent, but it's far from infinite.

Was curious, did the math: 3-5K gallons * 6 cyl * 25 mpg = 450,000 to 750,000 miles.

removed my incorrect math re: dollars of fuel per engine

3,000 gallons per cylinder * 6 cylinders * $4 per gallon = $72,000

5,000 gallons per cylinder * 6 cylinders * $4 per gallon = $120,000

Double-check your math: it's $4 per gallon, not $4 per mile.

If you're putting 5,000 gallons through each of six cylinders at $4 per gallon, that works out to $120,000 of gas. Certainly outweighs the cost of the engine by a decent factor.
