A bit of poking about on the web produced the following page
http://www.prime-mover.org/Engines/GArticles/bsfc.html

Which, although primarily about airplane engines, has an interesting table
of Brake Specific Fuel Consumption (BSFC) that I've taken the liberty of
translating to horsepower/gallons/hour (assuming a nominal 6 lb/gal for
fuel) :

18-23 Large industrial four-stroke diesel engines (very small hp/weight
ratios)
17-21 Other four-stroke diesel engines
16-19 Two-stroke diesel engines
14-16 Fuel injected four-stroke gasoline aircraft engines
13-15 Fuel injected four-stroke gasoline automobile engines
13-14 Carburetted four-stroke gasoline aircraft engines
10-13 Carburetted four-stroke automobile engines
 11- Two stroke gasoline engines
9-11 Four-stroke aircraft engine takeoff fuel flows
