ANYTHING NEW ON THE MOBIL 1 FRONT?

In the April issue Of Hemmings Sports & Exotics on page 72 (tech section: Fix it Again,Tony) a question was raised about the ZDDP additive not being in the newer API approved oils.
Here is the Tech guy's comments:
" If you are using oils with API approvals, there are additives you can add to restore ZDDP content. A good I'd use is Lucas BReak-in oil addive (Part #10063)."
Has anyone tried this?

There are several pitfalls in pursuing your own chemistry,...
Although one wants high ZDDP content for engine break-in, too much ZDDP in the oil beyond that point is just as bad as too little. One can read a littany of SAE papers written on this subject for the details (Charles@LN Engineering and I have both done so and a bibliography is listed on his website). Knowing the effects of excessive ZDDP and other elements, we use engine break-in additives very selectively.
Unless one invests the time and resources to perform extensive oil analysis for both the base motor oil and the choice of additive, you'll not know how much to use to reach the desired 1200-1400ppm levels.
While we use such additives for initial engine startup on the dyno, my very best advice is to stay away from "self-fortification" and buy a motor oil that contains what you need.

Thanks for the clarification regarding tweaking the oil.
What do you recommend then for a 97 993 that is from April through November in northern Arizona where the temperture range is 50-90 degrees?
The primary driving is done on the open road at fairly high speeds.
Thanks for for thoughts.

I would use either Brad-Penn 20w-50, Swepco 306 20w-50, Royal Purple 20w-50 MC oil, or Mobil 1 Twin-0il 20w-50.
No matter what you choose, don't skimp on changing it often, too,....

Steve, congrats on your 6,000 post milestone. I know I speak for many when I say that your knowledge and dedication to your craft, not to mention your generous contributions to this board, make owning a Porsche a greater experience. Thanks so much.

Steve,
Assuming I switch to Brad-Penn 20w-50, Swepco 306 20w-50, Royal Purple 20w-50 MC oil, or Mobil 1 Twin-0il 20w-50:
What is your recommended oil and filter(s) change interval for a DE driven car - typically 4-5 sessions at 20 minutes each per day, reasonably hard running but I've never seen temps above 248 and it typically runs at 220.
Thanks Steve!

My local independent Porsche specialist just performed the first oil change on my new 993. They used Amsoil AMO 10/40 (or ARO if you want 20w50). According to the 2007 Amsoil TSB, both oils have 1265 ppm P and 1378 ppm Zn which is pretty high. This seems like it would be an acceptable oil.

As an ex 993 owner, and hope to be future owner, I've following this thread closely.
Steve/Charles.....would your recommendations for Brad Penn in dual use street/track 1992 968 be the same as for the air/oil cooled cars. What weight etc.
Thanks......Jim

Charles,
Could you recommend an oil for my diesel truck?....2006 dodge cummins. I currently use Rotella 5w-40 synthetic and mobil one filter. Also, for the BP20w-50, does this come in gallon containers?
Thanks very much for your contributions here :-)

The Rotella T synthetic 5w40 is still the old, CI-4 rated version (at least as far as I know). You should still be fine. That said, once they phase out that product too, I would just stick to a CI-4 rated oil for a pre-2007 diesel engine, as recommended by a few different fleet service magazines. Just as with our Porsches, Swepco 15w40 would be an appropriate for your cummins.
