Cummins Diesel Engine Fuel Requirements
Cummins diesel engines will run on a great variety of fuels, but some fuels will give better performance, higher efficiency, improved reliability and lower maintenance costs than others. Cummins requires Ultra Low Sulfur Diesel (ULSD) for the following engines:
- 2007 or later engines in the US and Canada equipped with a DPF (including Tier 4 Interim)
- Engines operating where regional, national or international regulations require the use of ULSD in diesel engines
