Oil testing

I've finally gotten around to entering in the results of all the oil samples I had Staveley Services look at for me. The results are quite revealing... If you haven't been following along, most recently oil manufacturers have been reducing the anti-wear additive ZDDP because of longer factory emissions warranties - ZDDP causes damage to catalytic converters. For our purpose, we wanted to see which oils had the target .12-.14% (1200-1400 ppm) of Zn and P. Results are about half way down the page.
