You'll experience a bit of a power reduction since Kerosene or Diesel #1 has less BTU's than Diesel #2. Here's the BTU per gallon content of various fuels:
Methanol- 62,800
Ethanol- 84,400
Propane- 92,000
Gasoline- 125,000
Kerosene- 134,000
Diesel #2- 139,000
Diesel #6 (bunker oil like what ships burn)- 150,000. Just thought you might like to know. Good Luck, TomC
