New technology can result in 10% to 30% fuel cost savings, allowing engines to use the same fuel, but at much higher fuel conversion efficiency.

Fuel conversion efficiency is a measure of how effectively fuel is transformed into usable energy. Each type of fuel has a specific energy-producing potential per unit of weight, but some or most of that potential is lost in existing internal combustion engines.

While 100% efficiency is always the goal, in practice the fuel conversion efficiency..
