Diesel engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups. The two groups are called the preferred fuels and the permissible fuels.The preferred fuels provide maximum engine service life and performance. The preferred fuels are distillate fuels. These fuels are commonly called diesel fuel, furnace oil, gas oil, or kerosene. These fuels must meet the "Caterpillar Specification for Distillate Diesel Fuel for On-Highway Diesel Engines" found in this Special Publication, "Distillate Diesel Fuel (Fuel Recommendations for On-Highway Diesel Engines)" article.Note: The permissible fuels are some crude oils, some blends of crude oil with distillate fuel, some biodiesel, and some marine diesel fuel. These fuels are not suitable for use in all engine applications. The acceptability of these fuels for use is determined on a case by case basis. A complete fuel analysis is required. Consult your Caterpillar dealer for further information. For information concerning biodiesel/biodiesel blends, refer to this Special Publication, "Biodiesel" article.Note: With the exception of some biodiesel, permissible fuels are not acceptable for use in on-highway applications.
Use of permissible fuels can result in higher maintenance costs and reduced engine service life.
