Kerosene or Diesel Fuel – Which is Best for a Hot Water Pressure Washer?

It depends on your engine. Some newer diesel engines include kerosene on their list of approved fuels. Because kerosene is distilled into a pure fuel, it has no lubricant additives like diesel does, and burns cooler. Therefore, if you choose to run kerosene in your diesel engine, it’s important to add the right lubricant to the fuel – otherwise, it can cause strain on your injector pump. Marvel Mystery Oil is a good choice, and proper lubrication can be achieved by adding one quart to every twenty gallons of kerosene.
