15W-50 Mobil 1
You can by it at Costco by the case here in Atlanta (No Affil) Just bought 2 today.

M1 5W-50 and/or Castrol Syntec 5W-50.

Mobil 1 15W-50, but I really want to use something else. Thinking of Redline. Using Mobil 1 V Twin Motorcycle 10W-40 oil in the Sequoia and Miata and might start using the 20W-50 in the 993.

Quick question. What weight oil do you guys run in your 993 if you still have the hydraulic cams, rather than a solid setup? What I am getting at, is that I have a lot of people who own both 993s and earlier cars, and would like to use just one oil, say Swepco 306 15w40 or Brad Penn 20w50. If M1 15w50 had been working for you guys, then the other two products more than likely won't have any problem residing in a hydraulic 993.
5W, or a 10W and 15W, but maybe significant diff. between a 0W/5W and a
15W/20W? Just wondering if anyone has thought about this or done any real analytical research?

Charles, hopefully a simple question. If what I have read is accurate, and 90%+ of engine wear occurs on start up?, then doesn't it make sense to have a lighter weight oil to "ostensibly" circulate the oil through the engine quicker? Or are the differences between the grades for what I will call time-to-lube..TTL (how long it takes oil to circulate through a dry engine") negligible? E.g., no significant difference between TTL for a 0W and
5W, or a 10W and 15W, but maybe significant diff. between a 0W/5W and a
15W/20W? Just wondering if anyone has thought about this or done any real analytical research?

That's a good point--if ever there was an argument for running two different oils, the 993 is it. In the Summer, oil temps can hit 248° mark (on the gauge--who knows how high in, say, the cylinder head). Certainly reason enough to run high quality synthetic of adequate high-temp viscosity. In the Winter, I can go weeks without getting it over the 194° mark, even driving pretty hard.
I could probably run 0W30 in the Winter and the total wear would be less.
