Designed Specifically For Hot Rods and Classics! From the leader in racing lubricants, a line of high performance synthetic oils designed for muscle car, hot rod and classic engines. Driven Hot Rod High Performance Synthetic Oils build on the original formula while adding critical additives to fight rust and corrosion even when your engine is not running. The additive technology used is the same that was developed for the U.S. Military for storage and shipping. Driven Hot Rod High Performance Synthetic Oils feature higher levels of Zinc (ZDDP) than regular oils to deliver proper anti-wear protection for older style push-rod and flat-tappet engines.
