If you run a high quality zinz oil and add some ZDDP or the Crane or Lucas additive is it possible to have too much zinc in your oil? Whats the best additive Lucas, Crane or ZDDP? Sam

Sam,
Read the TechBriefs on the website.
ZDDPlus
TechBriefs #5 & #6 address racing and diesel oils, respectively. TechBrief #7 on 'dosing' and TechBrief #8 on 'market viewpoint'.
It is the only product I use in my Camaros...and have a standing offer to get it to you at less expense than the $9.95 + UPS shipping on the Kirban website. Discounts to all SYC members.
