I was barraged by TV commercials about "viscosity and thermal breakdown" throughout my youth, and those relentless ad campaigns enabled me to visualize the tortuous conditions inside a combustion chamber. But there's nothing quite like picking an expert's brain to reinforce how much you don't know about the intricacies of engine lubrication.

A recent chat with Royal Purple's Kyle Neal uncovered a few of the details behind the black art (pun intended) of oil design. Turns out that 75 to 80 percent of oil is made of a base stock, but it's the additives, which constitute the last 20 percent or so, that differentiate different brands like Castrol, Mobil, and the like. Those chemical x factors can incorporate everything from detergents and corrosion inhibitors to acid neutralizers and adhesion agents which help keep the oil on key engine parts at startup, where 80 percent of wear occurs. While some companies buy their additives from multi-billion dollar companies like Lubrizol, which is owned by investment tycoon Warren Buffett, Royal Purple has manufactured their own additives for 26 years running.

The Porter, Texas-based company was named after the combination of red and blue die which gave it a "royal" hue, and their proprietary Synerlec is one of the common threads between their range of products, which encompass everything from fuel injection detergents to Max Cleaner, which helps eliminate carbon soot that can develop on motorcycle engine intakes due to the high ethanol content in today's fuel. The science behind these products may not be as catchy as slickly produced TV ads, but it sure is fascinating to gearhead geeks like me.
