Porsche approved motor oils
 

I have been trying to find the most current Porsche approved motor oils. I found one dated Dec 21, 2007 on the Pelican Parts website (see http://forums.pelicanparts.com/showthread.php?t=393996 ).

Is there a more recent one? If so, does somebody have a link to the site that has it?

Thanks.

That's a good enough list for you to make a decision on an oil if your criteria is to only use approved oils.

Of the approved oils, our recommendation is for Motul 8100 X-Cess 5w40. It carries an API SL rating and has more anti-wear additives and improved HTHS film strength than M1.

Charles,

What would you recommend that isn't on the official approved list and how does it compare to the Motul?


Thanks,

I'd say that's probably the one I'll choose.

To continue the discussion, however: If one ignores the Porsche approved oils list, would your recommendation differ?

Is M1 no longer "approved" by Porsche?

+1, Charles, what do you and Jake recommend outside of what's on that list? How does Royal Purple or Redline stack up? I'm thinking of switching from M1, but I'm a bit apprehensive. Are these aftermarket oils really going to make a significant difference in wear ect over M1? I know this topic has been talked about to death on here, but I want your advice.

M1 is on the Porsche list in both 5W and 0W-40. And I think at least one 50. Good luck trying to find 5W-40 in the US.

And the Motul X-Cess's SL rating is as low as you would want to go.

Of the not-recommended oils, I bought Motul 300V from Charles after much research and careful consideration. Yes, it is very expensive.

I meant to add that the TSB with approved oils is available to Contributing Members at RennTech. And Mike Focke had it posted somewhere, I think. Maybe his site or Babblers.

Neither Charles or Jake are going to recommend an oil outright, but if you "read between" the lines, you'll learn what not to put in your car (read M1).

I usually run Royal Purple 10W40, but may try Motul or Redline next time around?

If my TWC burns up, I guess I'll figure it out (car just reached 16k miles).

A 2008 version is in the wild...
 

Though not in the TSB format. Here .

I may try the Motul next time. About the same price as the Red Line 5W40 that I have been using the past 3 years.

That's interesting, as I've been watching your posts to gain any insight of how RedLine is working out for you since I've been using the Motul 8100 Excess!

BTW, I noticed that the Motul 8100 Excess doesn't look like it was going to be renewed (expired 10-23-2008) under the last Approved Oil List (9-25-2008) -- could of been an annotation oversight by Porsche.

Attached my current UOA history up to the last oil change. If anyone wants the raw data Excel spreadsheet to track your own UOAs, PM me your email.

Last year I put Castrol Syntec 5W-50 in my '02. I'm pretty sure it used to be an approved oil, but now I see that most 5W-50s are off the list. Is this because they don't approve seasonal oils any more based on the text in the document(being so thick I guess)

Should I not use 5W-50 any more? It used to be okay and now it's dangerous? I don't understand how these approvals can change year to year. Is it okay to drive it in hotter weather only(I don't drive in the winter months anyway).

The only Porsche approve 5W50 is Mobil 1. Very hard to find in the USA. Canada has it at Wal-Mart.

Paul, I still like the Red Line very much. Just willing to try other oils that appear better than Mobil 1. Plus, the Motul is on the "list".

I don't know or care what the "best" oil is. I just want something that is better than Mobil 1.

I get less startup valve train noise with Motul 8100 Excess vs M1 0W-40 in an MB E320 so that's why I went with Motul. How's RedLine on this issue? With their high percentage of ester basestock, the noise (I assume) would be less. I was looking at RLI's HOBS oils but they don't make the HTHS reqt of Porsche (>= 3.5 cP).

My car sounds the same on start-up; after +5 months of winter storage, or a cold start-up in March or July, or hot start-up after a long drive. No valve train noise.

I attribute this to the Red Line and a diligent & easy winter hibernation routine.

Sheesh, makes Royal Purple look like a bargain.

Really? I thought RP was about $9 a quart too.

If you buy the 20 quart pail, it's about $7.15 per quart.

Thx, I appreciate the info.
