First, since NEO contains no hydrocarbons, it will not contribute to hydrocarbon emissions. Second, NEO has been proven to keep the pollution control PCV valve completely clean for at least 25,000 miles. Engines with clean pollution equipment operate better, save money, and provide extra gasoline mileage. This is true economy. To understand how NEO motor oils work with the environment we must have a thorough understanding of the important role played by the oil in an internal combustion engine.
Engine oil has three main functions.
First, it must lubricate moving parts by providing a thin film which actually prevents the parts from scuffing and also reduces heat created by friction. Second, oil must act as a cooling fluid to assist in dissipating the intense heat generated by combustion which can quickly reduce an engine to scrap. Third, it must flush moving parts to clean them of abrasive particles which cause excessive wear and premature engine failure. The heat in an engine acts on conventional hydrocarbon oil in the crankcase much as it does in the refining process which originally produced the motor oil. It breaks down into lighter and heavier molecules.
