Modern engine designs and oils have done a great job of reducing emissions and protecting emissions control equipment. However, modern oils have wreaked havoc on older engines. The reduction of emissions in modern cars has coincided with a reduction in traditional anti-wear additives (i.e. ZDDP) in modern oils, and that is bad news for your flat tappet camshaft.

The Driven HR Series Engine Oils deliver the chemistry that classic cars, muscle cars and historic cars need. Because these cars are not daily drivers, Driven Hot Rod Oil also delivers storage protection additives to guard your engine from rust and corrosion. Developed specifically for older cars, no other oil provides this unique combination of lubricant chemistry.
