With the 2007 release of the ISL G engine, the L Gas Plus is no longer available. Customers with the L Gas Plus will continue to be supported by the Cummins distributor and service network.

The 8.9 litre L Gas Plus combines all the advantages of clean burning natural gas with power and torque for transit (40 foot, double deck, or articulated), heavy refuse compactor, refuse roll-off. and local distribution (heavy straight trucks as well as 4X2 tractors).
