Information:
These recommendations are subject to change without notice. Consult your local Cat dealer for the most up to date recommendations.
Diesel engines may 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 “Cat Specification for Distillate Diesel Fuel for Off-Highway Diesel Engines” found in this Special Publication, "Distillate Diesel Fuel" article.The permissible fuels are some crude oils, some blends of crude oil with distillate fuel, 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 Cat dealer for further information. Biodiesel fuel is permissible for use in Cat engines. Follow all the recommendations and guidelines given in this Special Publication, "Biodiesel" article.Note: Except for 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.
Note: Use of fuels that do not meet at least the minimum performance recommendations and/or requirements may lead to lower compartment performance and/or compartment failure. Problems/failures that are caused by using fuels that do not meet the minimum recommended and/or required performance level are not Cat factory defects and therefore are NOT covered by the Cat warranty. The fuel supplier and customer are responsible.
