Exactly. The same can be said for posts you don't like. I excercised the free will to post what I wanted to, just as you stated. I didn't insult anyone, I simply noted a fact.

AFA flashing once too many, I didn't see anything on the list. But, then, searching for things seems to be more easily done from a top level google search than on the list itself. I find that a list search gives me a bazillion irrelevant hits.

I'm going to order a litre just to have it!
I would be interested in seeing the technical specifications for the oil, 10W-60 seems a little on the thick side to me. I normally run 5w-40.

This is a very hot topic in the Enzo forum. jk
In all seriousness, I haven't heard Porsche explain how they go from recommending M1 0w-40 to this 10W-60, what's the "special" formula, nor have I heard the oil gurus view of the 10W-60 pros or cons.

Normally, an air-cooled Porsche should be using 15-50 or 20-50. 5w-40 is not correct, especially for hot climates. Its also important to get sufficient ZDDP to protect our old, flat tappet engines.

I wouldn't use anyones's 10w-60 oil in my 993's
Porsche lost all credibility wrt oil when they recommended M1 0w-40 oil for the older cars, it may be fine for newer cars designed for it but the reduced ZDDP clearly was not in the best interest for air cooled longevity.
the new 10w-60 may be fine in all other respects but 60 is too heavy
Read your manuals,
when new 993s were spec'ed to use synthetic oil 10w-40, 15w-40 and 15w-50 for temps mostly > 50 °F, 10w-40, 10w-30, and 5w-30 for temps mostly < 50 °F
or if using mineral oil 15w-40, straight 40 or 20w-50 for temps mostly > 50 °F, 15w-40, 10w-40, and 10w-30 for temps mostly < 50 °F and for temps mostly <14 °F 10w-3- or 5w-30 mineral oil
For racing use they used M1 5w-40 either synthetic or the old rally blend w/ Mobile lube SHC for the trans
Going back further in time my '76 Carrera 3.0 was to use mineral straight 30 for summer and straight 20 for winter(5 °F to 32 °F) use and straight 10 for temps constantly below 5 °F. This was later amended to included 20w/50 mineral and 15w-50 synthetic for summer use(above 50°F)
P levels in all cases at or above 1200PPM and Zn levels in all cases at or above 1300PPM

Bill - was 10W-60 an option at the time the 993 manuals were written? I'm thinking not. It might or might not be the right choice now. Have they published zinc levels for the new juice?

The only thing they have published is verbiage. You would think someone in the tower would realize that credibility was lost on this subject when they where recommending 0W-40 and would get in front of this with detailed specs…unless of course the new product is also lacking.
The rumor is a new TSB is suppose to come out to supersede the previous 0W-40 TSB. Should make good reading for some lawyers looking for their next class action lawsuit.

10w60 seems to be a very very good oil. low viscosity in cold, high in hot.

Your 993 and the 964 that came before it ALWAYS used a 40 weight. Mobil-1 15w50 and Quaker 20w50 were put on the approved list back in 1992 because of carbon issues experienced on valves with the oil that dealerships in North America were using, not because the 40 weight "was too thin" and suffered from heat related issues.

Bill V. is spot on,.......
Given the packaging of these new products are pretty cool, I bought one of each to add to my oil can collection (dating back to 1960 when I started working on cars).
While these may be fine products, I simply don't see a need to use them given the excellent, well-proven alternatives that are currently available for less $$.
(For those with a technical bent who are curious, we found that 15w-40 oils made significantly more power on the dyno compared to heavier viscosities such as 15w-50 & 20w-50, in back-to-back testing. That said, certain environments call for the thicker stuff when outside air temps are over 100 deg F and/or an engine has a lot of miles on it where engine clearances are wider.)
