I've seen CP in their transmission products, but not in the motor oil products. I got MSDS from lots of thier stuff. I'm pretty darn sure this is CP free.
The results of using this in an older worn engine has met the claims on the can of smoother running, and restored power.
I'm pretty sure this isn't a CP product... More on the lines of what that RESTORE stuff is like.
I have emailed them about these things, and have been told the following..
"All Justice Brothers’ products are safe for use with vehicles equipped with catalytic converters when used as directed. Justice Brothers’ products are also safe for oxygen sensors, or any other sensor for that matter. I believe the reference you’re citing about restricting anti-wear additives in oil is partly due to zinc or ZDDP. The presence of zinc, also referred to as ZDDP, has been shown in studies to be harmful to the environment. Justice Brothers’ products do not contain zinc, ZDDP or Teflon®. Justice Brothers’ oil additives contain JB Metal Conditioner® which reduces friction and wear so the assembly runs cooler, quieter and smoother."
The MSDS I have is from 1998, so reformulated it may be. But looking at their product lines, the only think that shows a trace of CP is transmission products.
