I received a message from my local indy shop to move away from Mobil1 as the formula has changed?

Has anyone else heard this as well?

I haven't heard that, but my Porsche dealer has switched to Valvoline synthetic. I'm not sure why.

If you're not trolling, yes, the formula changed 2-3 years ago.

Here's a good overview: http://www.lnengineering.com/oil.html

So I'll ask the loaded question...still a good idea to use???

I've used it for my two oil changes so far.

Is there a formulated list of let's say, TOP 3 oils which we can all agree on?

Or let's say a list of TOP 5 oils which are supreme?

I used Shell Helix Ultra in the 996 (which is now Quaker Q-Power) 5w/40

(hard to find)

and NO - we wont agree on the top 3.... but we can agree an what NOT to use (maybe)

fpena944

I doubt there can even be an agreement on what not to use - unless we're talking hair grease or vegetable oil!

I want in. Pass the salt..

Really. Good info here for our engines: http://www.lnengineering.com/oil.html#m96

My toplist for 5W40 oils would be:

1) Motul 300V (amazing, oil-of-the-Gods, priced to match)
2) Motul 8100 (SL, Porsche approved)
3) Redline
4) Castrol Syntec (SL, Porsche approved)

That would be some real good info though! TOP 5 oils...... Hmmmmm

Im sticking to my 15w-50....

In any debate, the amount of rhetorical heat is always inversely proportional to the amount of tangible evidence available.

I think you need to use something that is light enough to lubricate the valve gear quickly on startup for the conditions you drive in, and you need to change it a lot more often than Porsche recommends. After that, if it's on the list, I really don't think it matters what you use.

Oh boy, and oil thread!!!!! We haven't had one of these for a while!

Chao, I need some of that popcorn. Here are a few brews!

I'm a little confused the owners manual does not even mention 0W-40 I was going to use 10W-40 when I do my oil changes would this be wrong? Its one of the oils listed in the owners manual.
