Reducing CO2 emissions and meeting 2017 Greenhouse Gas (GHG17) requirements means better fuel economy. Compare how our GHG17 Compliant Detroit™ engines stack up against GHG14 engines. Our GHG17 engines provide better fuel economy while using a slightly higher amount of Diesel Exhaust Fluid (DEF). See for yourself how these engines will affect your operating costs.
