Description

GM Engine Oil Supplement for Classic & Antique Engines.

Why do we need an oil rich in ZDDP? This compound bonds with the ferrous elements in your engine and provides a protective anti-scuffing function that prevents damage at the points that experience the highest metal to metal pressures. For classic car engines with flat tappets, the major pressure point is where the cam slides against the tappet face. These pressures are worst with engines that have heavy valve springs – for example, those with aggressive cam profiles, large valves and/or high rev limits. Although our engines have big valves, our cam profiles are mild and rev limits low. This puts our engines at less immediate risk than say a vintage Porsche 356 or 396 Chevelle. These engines accumulate cam wear in their engines at a faster rate, and we can thank ZDDP formulated additives for determining the root cause and finding a path to salvation.
