(1)

Cat diesel engines are required to use ULSD (ultra-low sulfur

diesel fuel with 15 ppm of sulfur or less) or ULSD blended with

the following lower-carbon intensity fuels up to:

 20% biodiesel FAME (fatty acid methyl ester)*

 100% renewable diesel, HVO (hydrogenated vegetable oil)

and GTL (gas-to-liquid) fuels

Refer to guidelines for successful application. Please consult your

Cat dealer or “Caterpillar Machine Fluids Recommendations”

(SEBU6250) for details.

• Engines with no aftertreatment devices can use higher blends,

Tailpipe greenhouse gas emissions from lower-carbon intensity fuels

are essentially the same as traditional fuels.
