Zinc dialkyl dithiophosphate (often called ZDDP) is an anti-wear additive added to all modern synthetic engine oils. ZDDP is a heat-activated component that provides protection in areas of higher friction. Too much ZDDP can negatively affect your catalytic converter or DPF so it's important to choose an oil with the right level of additives for your vehicle.

What is ZDDP? Does zinc in oil add any benefit? Do I need ZDDP? We get a LOT of questions about ZDDP. Enough time has passed from where ZDDP was common that a lot of people don’t know about it. Some even think it’s a myth! If you need ZDDP and you don’t run it, you could be staring down the engine failure. We wrote a guide to help understand the benefits of ZDDP and how to tell if you need it or not. For a little automotive chemistry, check out our article about ZDDP: https://fal.cn/3d4A5 | Spee
