Recommendations for Diesel Fuel
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
The permissible fuels are crude oils or blended fuels. Use of
these fuels can result in higher maintenance costs and in
reduced engine service life.
Diesel fuels that meet the specifications in table will provide
these benefits. In North America, diesel fuel that is identified
as No. 1-D and No. 2-D in "ASTM D975" generally meet these
specifications. This table is for diesel fuels that are distilled
from crude oil. Diesel fuels from other sources could exhibit
detrimental properties that are not defined or controlled by this
