Friction-reducing lubricants make your engine run easier and cooler. Avoiding high heat will add thousands of miles to an engine's life while improving overall performance.

In older cars that have many more miles on the road and more oxide deposits slowing down their moving parts, each loose particle is its own conductor of heat, increasing the damage being caused to the engine.

While an engine lubricant applied to new cars is recommended, in older cars it is a requirement for increased horsepower and fuel economy.

A Southwest Research Institute article published in Technology Today, citing a 2001 EPA study, points to the demand for technology to improve fuel economy.

"Only about 15 percent of the energy content of the gasoline in a vehicle's tank actually moves the car down the road," the article states. "About two-thirds of the available energy in the fuel is rejected as heat in the exhaust and coolant or frictional losses.

"Energy is lost to engine friction, pumping losses, drivetrain friction and slippage, the operation of accessories such as air-conditioning, aerodynamic drag, tire rolling resistance and idling in traffic. Each of these losses is an opportunity for advanced technology to improve fuel economy."
