For nearly 20 years, biodiesel has been approved by Cummins for use in its on-highway diesel engines.
Cummins’ iconic workhorse, the X15 diesel, is approved to run up to B20 which contains up to 20% biodiesel mostly obtained from soybeans.
Fleets and owner-operators using biodiesel in the X15 have long-enjoyed greater lubricity, lower emissions and higher cetane values over conventional diesel.
