I've used Blackstone for a few years now on other cars. I had them test the mystery oil my 993 came with to get a baseline and make sure there were no wear metals. I intend to have them test going forward.

Having read the article you have send around (which is great) what are we going with on the oil front. I think I speak for alot of people on this board when I say that the car sees summer street use, spirited driving and 5 to 10 track weekends a season. I have been a devoted user of Mobil1 15W-50, and their 90W gear oil, what are you recommending now, having this info. Do you agree with the 20W-50 motorcycle oil?

PO religiously used Mobil 1 15W50 since 1996.
No drips or leaks EVER and she uses a quart approx. 2 to 2.5 thousand miles.
I only use Mobil 1 15W50 (SL) during my oil changes and also slip in a quart of Lucas.
No drips or leaks, quiet running engine, still uses a quart every 2.5K miles or so.
No complaints.
(And yes, I drive it year-round ...OK, OK, I try to avoid the salt-snow days).

(Got it two years ago at 19+K on the odometer, she's now at 28K, and I'm just about to get the 30K service (and Bilstein-fandango) done.)

Yeah, don't worry, I've seen/read all the pros and cons about Lucas and 'frothing' etc. etc.
Based on what I read/saw I *still* made the decision to use a quart in the p-car.
Have used Lucas in the wife's Ford for the last 8+ years (and 80K miles) with no probems and in the p-car, now, for approx. 2 years, with nary a hiccup wrt oil pressure, consumption, weird sounds, etc. etc. etc.
As always, YMMV, mine seems to be OK!

The bottom line is that if the bottle has "API SM/SL" on it, its NOT the same good stuff as you've been using.
Last night after work, I perused the isles at my local Walmart looking at various oils to see what was currently available. All of the Mobil 1 formulations were now the new SM, the Royal Purple was still SL (this may change), Rotella & Delo were still SL or CJ but that will change soon as diesel oils reduce the Zn, P and S content.
Look carefully at the bottles as that tells the tale.
There is a LOT of activity on this subject over on Pelican's 911 Forum in a few threads and its really highly recommended reading!! You'll note a few comments on Lucas products, too.
Mr. Hillary's postings were very enlightening & educational but one needs to remember that the oil formulations sold overseas are NOT the same things as we have here, especially now.

FYI, the actual vendor isn't Amazon, it's CDOC: http://www.cdoc.com/products.asp?str=5010&name=FLUIDS

While the SM formulation is not as good as the SL, I wonder is it still good enough?
