I am thinking through adding a multi fuel (Gasoline/propane/natural Gas) 
conversion for my Craftsman 4KW  generator, and wondered what the generator 
would consume per hour in the other fuels, and found a good site with full 
explantions of how to compute consumption with the other fuels.

Propane seems to be the most practical/long term/safe fuel compared to 

So this site, among a lot of other useful info, gives some useful info, 
copied here.


It requires 2 horsepower to produce 1000 watts of energy per hour under load

Under load, each horsepower consumes 10,000 BTU per hour

Propane contains 92,000 BTU per gallon   Gasoline about 110,000 BTU per 

Propane weighs 4.2 pounds per gallon

A very useful resource..
