Can you guys weigh in the Idemitsu oil with respect to ZDDP levels and such in reference to this thread:

Thanks.

 

I didn't get to read the entire thread, but it does seem interesting. Howard Colman is a sharp guy with good information. As for the oil... I don't have an answer.

I'm sure you can get all the oil details from the engineers at http://www.idemitsu-usa.com/

We've been using the different oils with no problems for the past couple of years.
