We dont get low winter temps, and we get in the 90's in summer, better protection. M1 5w-50 is on the Porsche recommended oil list.

​​​​​I use 5W50 here in Atlanta, as recommended by Kevin at UMW.

Hmm. I too live in the SE, I may give this a shot next time I change the oil!

Bouncy needle can sometimes be the oil pressure sending unit - I replaced mine and my gauge stopped bouncing around.

Got busy with work and finally able to get a response back from the indy who did the oil change. FWIW, this is a fairly reputable Indy who does quite a bit of work on Audi's and Porsche's.

Their response to me was that they purposely underfill the oil from max b/c "maxing it out is hard on the oil separator and can cause them to prematurely fail." They also used Motul 5W/40 European blend and full synthetic.

Has anyone heard this reasoning before? Not trying to make a mountain of a mole hill, and from my conversations with the tech and owner, they sound like they know what they are doing, but just trying to learn more about these machines...

Interesting logic, I've never heard of that- I'm not even sure the mezger engines have an air/oil separator like the standard carreras do, never able to find anything to confirm its existence..The amount showed on the electronic check is a window of what is in the reservoir, it isn't a measure of what is in the crankcase like other cars.. As long as it is somewhere in that range it is ok. Each bar is approx 1/4 of a quart if you want to add some to help you sleep better.

Good point. IIRC the air/oil separator in the non turbo Carrera's/Boxster is prone to failure. A non issue on these turbos though....

I did a quick google search and I can't determine if the turbos have some kind of oil separator.

I came across this thread: https://rennlist.com/forums/996-foru...ere-is-it.html

Perhaps Mac or another Mezger engine expert can chime in?

I've got some Motul 5w40 if you want to swing by and top it up.

another advantage of running 5/50 is it really quiets down any "rattle" at idle.

I've used M1 5w50 per same recommendation as well for better shear resistance.
Next oil change I do I'm sending 2 samples to Blackstone for analysis since I haven't gotten around to sending the one I took at last change.
Figure it will be interesting to see what change in results come up.

Thanks, will keep that in mind!

Thinking maybe next time I should try and do my own oil change. There is a DIY video thread on 6speed. Seems simple enough....

Good to know, thanks.

It is very easy. I was looking at it the other day and I think I could do it without even having to use a jack next time lol

Reminds me of a guy I saw change his truck's oil on a constriction site when I was in school. Just pulled up over a small hole he dug...hopefully the new owners didn't plant their tomatoes there.

closest i get any *analysis* is cutting open my filter. i suppose if ya find something shiny then? it's a bit late

Found above link on another thread on RL. On page 15 of the brochure in above link, Porsche labels a component in the engine as "oil tank with oil separator."

Guess this answers my question on whether the 996 turbo has an oil separator or not.... Now I'm still researching to see if filling the oil to max level has an adverse effects of said oil separator (as this indy shop states).
