Porsche classic oil
I know I'm sorry to post another oil topic. I've been using mobil 1 15W50 since my top end rebuild and have been happy. Virtually zero oil consumption 
. I work for a dealer group that also owns the Porsche dealership. I will be going there in the spring for a paint correction and coating (friend there is the detail manager and is a crazy good polisher). Anyways, I will need an oil change in the spring as I didn't get the chance to do it before storing the car for the winter. I figured I'd kill two birds with one stone and have the oil changed while the car was there getting paint corrected. They only use Porsche classic 10W60 oil however. Has anyone used it and would you recommend it?
Thanks in advance!

Porsche have used it in my car the two last oil changes and they will do so next time as well.
I trust Porsche regarding this oil but I also trust Steve Weiner here on Rennlist a little bit more and he for sure recomends another oil.
How do You know if an oil "works"? Well if it does not leak, smoke or consumes then it must be perfect? well, You need an oil that protects the engine as much as possible from internal wear and then there are better oils than Porsche Classic's, even if that is a decent oil.
Oil threads demands this smiley!

We don't use the Porsche Classic oil for one main reason: insufficient ZDDP for the air-cooled engines we work on.
Brad-Penn (now Penngrade) is an excellent product, based on what I've observed in the inspection of internal parts over time. Valvoline VR1 is OK, too.

"They only use Porsche classic 10W60 oil, however." This is very odd as any other dealer will fill with Mobil 1 upon request. Especially since it is one of the approved oils by Porsche.
Tell them you will take your business elsewhere, they will change their tune as I have never seen a dealer turn away business over oil.

Derek,
The Mobil1 15-50w that you are currently using has enough ZDDP (1300 ppm I believe) to protect your air cooled motor, without needlessly clogging up the catalytic converter or needlessly wearing internal engine parts with too high a ZDDP rating.
1700 ppm ZDDP is fine for a new engine break in period, but detrimental to our broken-in engines and the cat, as previously mentioned.
Goofball hit the nail on the head re pricing on the Porsche classic engine oil.
Run what you brung (Mobil1 15-50), and you'll be just fine, with plenty of pocket money to treat yourself, the gf or the wifey!
P.S. I attached the most current, (Oct 2018) Mobil1 spec data sheet for zinc content for your review andconsideration.
Can you dig it? I knew ya could...Data talks, words without proof, walks...

With all the past discussion about oil for our cars, I find little about ester based synthetics vs. PAO based synthetics. I’m no petroleum engineer but from what I can ferret out it seems the ester based oils are superior. I believe Motul 9100 and Redline are tthe only ester basedoils in the US market. Is there a knowledgeable authority out there who can comment? In the past Steve W. has recommended Motul. I would tend to go with Steve’s recommendation as he has disassembled many engines.

Sorry to stir the oil pot, but I've been away from the forum for a while and just saw this.
I have been using M1 0w40 European Car Formula. With 140k miles a bit of a chain box leak, thinking I should switch to a 15w50 or 20w50.
It's a daily driver with no track use.
What are the top recommendations?
1 - Some other M1?
2 - Valvoline vr1 20w50 - Conventional or Synthetic?
3 - Brad Penn - 20w50 - Partial Synthetic?
4 - DT50 - 15w50 - Synthetic?
Thanks

JMHO,.......
Leave the 0w-40, 5w-40, and 5w-30 oils to the water-cooled cars. I've seen too many (expensive) issues to ever use those in air-cooled cars.
Stick to the 15w-40, 15w-50, & 20w-50 products unless you must drive in near arctic conditions.

Some of the recommended oils are difficult to obtain in the UK. A local well respected oils supplier advised this list of 10w40s:-
Fuchs ProR
Millers CFS
Gulf competition
Redline
other grades are available with minimum 1200 ZDDP
I went for the Fuchs aka Silcolene.
It would appear that competition oils are exempt from the ZDDP reduction as are 20/50 and 10/60 getting ZDDP levels from manufacturers is like getting blood from a stone. The supplier did not advise 10w/60 at all.
