Why You Need This
Modern motor oils lack the assortment of metals and minerals that old engines need to protect their insides from wear and excessive heat. One of the more important of these is zinc, a soft metal that acts as a cushion between hard metal parts. We offer this zinc ZDDP (zinc dialkyldithiophosphate) additive by to protect the hardened metal surfaces inside your engine—especially camshaft lobes and rocker arms, which are a common fail point in vintage Honda engines.
Zinc ZDDP stabilizes modern oil and protects against viscosity breakdown caused by thermal cycles. It reduces friction, especially at startup, which means less wear and a cooler-running engine. It also makes oil stickier so that it stays on metal parts and in cylinder bores instead of leaking back down into the sump, an important feature for engines that sit for long periods.
NOTE: We recommend using mineral-based diesel oils if possible - specifically 15W-40, instead of semi-synthetic (synthetic blended) motor oil for your vintage Honda motorcycles. Diesel oil contains extra metals, minerals, and detergents that keep old, air-cooled engines running at peak efficiency. If you're using regular motor oil in your engine, either automotive or motorcycle-specific, using the zinc additive is an absolute must. Additionally semi-synthetic or synthetic blend motor oil may cause the clutch friction discs to slip.
Installation Tip
Proper use of zinc ZDDP additive calls for adding two ounces of additive per quart of oil during oil changes. One 11-ounce bottle is good for two oil changes depending on your bike.
