Porsche factory approved oil for all models is Mobil 1 synthetic 0-40w.
My Porsche owners manual from 1986 approves of multi-viscosity oils including synthetics in the range of 10-30 & 10-40.
Porsche refers to these oil weights as "fuel effecient".

I'm surprised to hear some of you using the Mobil1 15-50. In Doug Hillary's "Oil Condition Report #10" he mentions that it is not approved by Porsche and recommends against it, with 5-40 grade being his preferred choice. That was back in Sept. '05. Have I missed something since?

Why does he say not to use a 15-50 weight? Just because it is not approved by Porsche? Or is there more info on why not to use it? I have not heard that before. I thought your location & weather you drive in would influence the weight you should use? Those in the snow & freezing versus those in the extreme heat. Isnt that why multi-viscosity oils are used? Then you can adjust depending upon your climate, etc.

Here is the link to it- https://rennlist.com/forums/showthre...0&page=1&pp=15
That was my take on what was said, especially reading posts #24-26. Maybe I misunderstood or took it out of context.

Whoa, bad thought on my part then. Of course My car was being used on the track which is why I choose the 15w-50. Guess I'll be changing back wards then. 5w-40 it is.

Doug said M1 15W50 is not specifically approved by Porsche. 15W50 is an approved viscosity according to the owner's manual scan in post #43 in that thread.

Interesting stuff guys,
I have spoken to doug in the past about buying his car.
He is a very nice guy and his car is looks awesome.
I mean no disrespect to him him but what qualifies him to be the guru of oils??
I only ask this as i have spoken to a porsche mechanic that is a 928 freak and he says mobil 1 is not good for 928's
also my engineer (im a boat skipper) also worked for porsche in the late 80's and early 90's and
he also says no good as its to thin.I was told this causes extra wear.
I look forward to comments.

Needless to say...he is very qualified and his opinions are very welcome. I just wish he could do something to cure this 5w-40 Truck/SUV formula shortage.

I just read the thread linked above and im impressed.
I wonder if there is a couple of different types of mobile 1 here in Aus as
he is using delvas 1 heavy duty commercial diesel.
That sounds a bit different to the usual Mobil 1 we have here.
Doug looks like you put allot of work into this so sorry for questioning your knowledge without doing
the homework.
