VoxPop®--Your online source for engine oil information.

Have you ever wondered about the oil you use in your car or truck? How well does it meet your specific needs? Is there really any difference between oils? And how do you know you're getting what you want and pay for?

Choosing a good engine oil is, by far, the least expensive insurance you can buy for your vehicle. VoxPop® can eliminate the guesswork so that you can tailor your choice of oil to your engine and driving conditions. Our goal is to help you make educated decisions when choosing an oil.

Here you will find answers to your questions regarding engine oil and lubrication. Find out more about engine oil functions and use our online glossary to learn about key lubricant properties that enhance engine performance. Visit our VoxPop Report eStore (click the'Ordering Information' tab at the left) to purchase our unique VoxPop® Engine Oil Report. This one-page sheet clearly and simply shows how an oil of your choice performed in nine critical lab tests. It compares your oil to other oils of the same viscosity grade and service classification and even shows the range of variation if several samples of your oil have been tested. Each purchased report comes with an Engine Oil Report Reference Sheet that explains the significance of each test with a glossary of terms, and an eBook which addresses common questions about oil and lubrication.

VoxPop® reports are based on thousands of commercial oil samples acquired by an independent organization called the Institute of Materials (IOM). Since 1984, IOM has been publishing test results on oil samples it collects randomly throughout North America, Europe, and Asia. Each year, IOM tests hundreds of samples of major and minor brands of oil to evaluate whether the samples perform according to the specifications set by the American Petroleum Institute (API), Society of Automotive Engineers (SAE), and the International Lubricant Standardization and Approval Committee (ILSAC) for their grade and service ratings.
