Novel Test Methods to Optimize Fuel Economy in Passenger Cars Using Organic Friction Modifiers

Fuel economy is overall a very high priority worldwide, but the value of fuel economy can vary to different stakeholders. Many governments set minimum fuel economy standards that force OEMs to make significant investment to achieve. Engine oils and friction modifiers can provide a small but cost-eff...
