This complete line of quality products is recognized by countless private motorists fleet managers and industrial administrators as the best and most cost-effective choice for increasing engine performance, reducing maintenance and prolonging vehicle and equipment life.

In 20 years, engine speeds have increased 50 percent. Modern engines are smaller, leaner-burning, hotter-running, have higher compressions and use smaller radiators and oil sumps. Many use turbochargers and multivalve heads which boost rpms and temperatures even higher.

Over the same period, oil drain intervals have increased as much as 300 percent. Modern engines produce more power with better fuel economy and fewer emissions than ever before, and the oil protecting them is working harder than ever, too.
