Valuable Aid in Meeting EPA Fuel Economy Standards
Viscosity modifiers are polymers that play a critical role in modern multi-grade engine oils. Part of EPA fuel economy testing is a cold start and drive test, and carmakers such as Honda have been able to increase their overall new car mileage ratings by blending super-thin, multi-grade oils such as 0W-20 and 0W-16. Thinner oil creates less drag inside the engine, freeing up power in cold start situations as well as in overall driving and ultimately increasing fuel mileage. High quality base stocks and engine oil viscosity modifiers combine to make this possible.
