Yes it would absolutely break you up in fuel costs!
They are OK for occasional use or for something like 47 is talking about but not for shop use. To equal a 5 HP (true 5 HP, not "peak") compressor would take at least a 10 HP gas engine and to get any real efficiency out of it you would need a two stage pump so the costs to build it would be more than a good electric compressor long before you would finish it unless you had a lot of the parts lying around already. When you figure just how much time a shop compressor runs and gas costing over 4 bucks a gallon the costs to run it would be staggering.
