So, I've spent a few hours reading all the oil threads I can find in the air cooled section of this site.
Seems that Brad Penn 20w-50 is the stuff for the older 911 and the NA 993s.
However, for the 993tt, which has those lovely hot turbos, is a dino oil sufficient?
I didn't get a straight answer in this forum using the search function, but it seems people are sticking with M1 15w-50 despite the alleged lack of ZDDP and other additives.
So, do I go with BP for the zddp but risk coking the turbos, or do I go M1 for its synthetic goodness but risk damaged valvetrain from lack of ZDDP?
thanks for any input, and sorry for another oil thread.

Mobil 1 15-50 for the turbos.
Someone (Steve W?) said that the Brad Penn is not adequate. <EDIT: It was not Steve W.>
RUF Dallas runs the Mobil 1 in my car. Works for me.

I've been running BP for two track seasons now and have nothing but good things to say. Blackstone oil analysis always comes back great and zero issues with the turbos

There is a reason why the 993TT came from the factory with a synthetic fill. The heat management is alot better vs a dino or semi-blend.
I would recommend the new Mobil 1 VTwin oil..
Do a search on the 996TT forum you will see a recent oil thread. It has a few good post to the Mobil website.

Kevin, thanks for the info, but I've read that the motorcycle oils lack the detergent qualities of a good automobile engine oil.
I've never seen so much controversy over oil!
any other input is great.

Go to the Mobil 1 website and search there Q @ A.. You will see this very same topic. The VTwin oil is very good. It does have additives FOR the aluminum components. The VTwin oil is designed for a 4 stroke, big bore air-cooled engine.
I'd run the Mobil 1 VTwin oil over Brad Penn in the 993TT engine.

how about this crazy idea:
6 quarts 0w-40
4 quarts of 15w-50
Any top offs would be in 15w-50
You get some decent cold weather flow, with pretty good hi temp protection
Thoughts?

LOL -- dont take me too seriously, I have trouble doing so myself!!
All I know is that I am hesitant to make changes in lubricants and perhaps someday I should, but at the moment I stay close to the M1 brand in 15w50 weight.

Is there any concern over oils (reformulated oils, from the original '96/'97 formulas) not having Zinc in them like they use to (for metal on metal wear)?
My shop recommends Swepco 306 for that reason.

Folks here is some good reading material.. I strongly recommend the Mobil VTwin 20W50 for our Turbocharged 993TT engines.

This is a good thread for those that have mechanics that recommend "other oils" over Mobil 1
https://www.mobiloil.com/USA-English...il_Claims.aspx
If you need to spend $300.00 on oil and want to fill good. Order in some Motul 300V..
