Steve, do you recommend this for a 911 with 118,000 miles on the engine? Basic engine is all stock, but a "top end" was done about 40,000 mi ago to do valve guides, etc. If recommended, should it be added at each oil change?

Its all about protecting the cams, rockers, and other EP parts from the accelerated wear that we've been seeing for awhile in engines that didn't have any issues such as plugged spraybars.

EOS is great stuff...there is another add pack available from Specialty Formulations which will boost the ZN and other anti-wear additives...It has been well received and tested in many circles...I have no affiliation, just a customer...

Yup, I bought it for $8.52 from my wife's Pontiac dealer, dropped in about 2 oz last night, and this morning was rewarded with a "wonderful aroma" coming from the tailpipe. Steve's assured me that's pretty normal.
A nice public "thanks Steve" for keeping us end-users up to speed with the necessities on our rides.

Its possible, but honestly I've never replaced a cat on a healthy car that was running well (not rich; not lean) and Z-S-P additives have been in motor oils since the 70's.
