Daytona1's newest Engine Treatment, ZL-1, is an unbeatable combination of Zinc (ZDDP) with the latest technology. They blended three different types of zinc polymers into a proprietary combination that creates outstanding protective barriers inside your engine. This new ZL-1 can be used during break-in with any gas, diesel, or propane engine.
And just like their XL-1, the ZL-1 works great in street cars, hot rods, tow vehicles, and for that extra protection and gas mileage for your daily driver. Use it on every oil change and you'll never wear out another bearing or cam shaft.
