ZDDP Plus Oil Additive 4 fl. oz

Product Review (submitted on May 22, 2010):

Just finished a big block Mopar for a guy. Has a "flat tappet" cam. busted that baby off with good old Penn 30w in it along with the ZDDP. Ran the cam in without any issues at all. Good oil pressure, right on temp, and no noises other than the VVVRRROOOOOOOMMM you expect from a well built Big Block Mopar.

Use it. It works
