ZDDPlus Engine Oil Additive
After 70+ years of trouble-free, metal-metal engine protection, ZDDP (Zinc Dialkyl Dithio Phosphate = Zinc and Phosphorus) is being removed from domestic motor oil by order of the E.P.A., as it degrades catalytic converters. If your engine was designed prior to the 1990s, your non-roller lifters require ZDDP in your motor oil to avoid premature deterioration. Don't let your lifters run metal-to-metal. Add the 4 fluid ounce contents of this ZddPlus bottle at every 4 to 5 quart oil change.
Not for use in cars with catalytic converters!
