Is your car due for an oil change?

   ZDDPlus Engine Oil Additive ZDDP
Time for an oil change! TwinCam engines, Renault engines, and early 907's without a catalytic converter should use oil with ZDDP.

Modern oils are hard on your old engine which was designed to run with motor oil containing ZDDP (Zinc Dialkyl Dithio Phosphate). Unfortunately this additive is no longer used in conventional and synthetic motor oils. 

ZDDP alters bearing and journal surface characteristics to prevent metal-to-metal contact, protecting camshafts and tappets especially. 

Just add ZDDPlus to every 4-5 quart oil change and your engine will be protected.  ZDDPlus works with any conventional or synthetic motor oil.  

Single 4 oz. bottle of ZDDPlus
