Auto Gas America – other heavy-duty highway engines: EPA certification of the L96 and LC8 dual-fuel engines for natural gas and petrol, 323 kW, 2013 to 2015 model years
Auto Gas America appears in the EPA certification database as a gas-conversion company, as the company name already shows. This page gathers the versions listed as L96 and LC8, the 6.0-litre GM V8 engines that the register could not assign to a named range, certified for optional operation on compressed natural gas or petrol.

The register lists here 2 versions from the 2013 to 2015 model years, each with 323 kW rated output, running on multi-port injection in dual-fuel mode with natural gas or petrol. Maximum torque stands at 375 Nm; the engines were certified under the EPA engine families DAGTE06.0HD1, DAGTE06.0HD2 and EAGTE06.0HD1.
Dual-fuel natural-gas/petrol engines based on the GM 6.0-litre V8 mainly go into heavy commercial-vehicle fleets switching to compressed natural gas as a cheaper or lower-emission fuel while retaining petrol as a fallback. Such conversions are typically carried out for fleet operators with their own gas infrastructure.
When buying used, what counts on these dual-fuel engines is the condition of the gas tanks, pressure regulator and gas lines, and the tightness of the connections, alongside the classic check of the ignition system and injectors; spare parts for the underlying GM V8 engine are widely available, and for the gas system through specialised conversion workshops.
