we all share the love lol.

I do have a question. The oil recommendations we all cite were developed about 15 years ago. I also know from a friend that is a design engineer for another manufacturer that factory recommendations are part joint marketing. My guess is Mobile paid Porsche a fee to have their logo on the underside of our rear deck lids. That doesn't mean M1 isn't good for our cars.

Given that oil formulations have changed, and possibly improved over the last 15 years, why is it assumed that the M1 formulation 15 years ago is superior to another brand's formulation today?

mobil 1 i great for our cars. my castrol edge experiment was that and little more. but i just today ordered two cases of M1 5/50 from my smog guy because i can get a good deal. it's 12 qt's so i'll have some extra fill.

but i'm sure i'll use castrol edge again also! but also.. fully agree on the reason the sticker is on our decklid as well as that m1 is good for the car LOL

 

Mobil 1 is the factory fill and I'm certain that there will be financial recompense involved, this does not however mean that you need to put Mobil 1 in your car. On the 2012 (can't find the newer one) Porsche Approved A40 oil list, covering all models from 1973 except for the Cayenne V6 and Cayenne Diesels, there are 177 oils from 74 manufacturers.

The article below gives an interesting insight into the Porsche oil testing and approval process.

^ that's been my contention all along or at least since i saw a 996 turbo approved oil list from porsche with more oils types and brands than i could remember.

 

mcbit, I'd run a higher weight that your 0W40. I recently tore down a set of K24's from Kuwait.. Very high heat, blued shafts, carbon build up. Order and import M1 5W50 if you have too.

 

Advice always appreciated Kevin, however I had a hard job convincing my Indy, the biggest Porsche specialist in the Gulf region, that I actually had a blown turbo. Blown turbos on Porsches over here are apparently like rocking horse sh*t.

Of the 5 Porsches I have owned in the UAE, the 996 tt (which blew a turbo and had a bore with a deep single score) is the only one that I don't know if it had been run on 0w40 continuously from new as the others had full OPC service histories up until I bought them. Zero engine related issues on any of the others.

As a senior manager responsible for the operation and maintenance division of a major international offshore contractor, I think I can safely say that we face no more lubrication related issues here than anywhere else.

With your cooked Kuwaiti turbo, I would suspect an oil supply or negligence issue before I would consider an oil quality issue.

 

mc, if you are a operations/maintenance manager, you most likely are sending your oil out for testing. Pay attention to what the 0W40 sheers down to. Depending on miles driven, you will be surprised at what the oil sheers down too. Over 90F Porsche recommends a 50 weight.

 

ah but Porsche also recommends M1 0w40 for all temperature ranges and the only 2 non Xw40 oils on the 2013 A40 approved list are Mobil oils.

Below are the Porsche recommendations for all A40 spec vehicles.

 

yeah, the 0/40 it shears down to the consistency of boiled crisco ! LOL. put that in your 25k$ motor over 100 degrees. like i say have at at! LOL

 

MC, you aren't including what Porsche has recommended in the owners manual. Page 134 discusses the operation of the vehicle such as speed, AND climate to determine the condition of the oil!

More importantly on page 137>> The viscosity of the engine oil for your Porsche HAS TO BE CHOSEN ACCORDINGLY TO THE AMBIENT TEMPERATURE given in the engine oil recommendation table (table lists 5W50).. Extreme temperature climate geographic areas need to use highest recommended weight, which is the 5W50.

 

Kevin,

without meaning to be argumentative, the manual which you are referring to obviously is not the same as the on which I am looking at...

There are only 2 references to oil viscosity in my manual which I present below and these propose exactly the same information which I have presented from the 2014 A40 recommendations:



...and the recommended oil table


what's new?

The fact of the matter is that, despite large ambient temperature differences between here and the majority of the states, our engines run at pretty much identical temperatures provided that their cooling systems are in good working order. In my current Cayenne i have seen 110C on the coolant temperature whilst ascending from 700m to 1400m on a 13 km road in mid summer at 50C however at the same time the oil temperature never moved from 90C and I have never seen it do so. I can't comment on the 996 tt as I can't read the oil temperature, but I have never seen the coolant temperature rise above 101C.

Over here cars die from accidents and neglect, but a normally maintained vehicle will almost never die from engine failure despite the use of the cheapest materials available. 90% of engine wear is a result of cold starting and in the winter we never see less than 12C (53F) and for 9 months of the year its greater than 30C (86F).

I am talking here from fact, personal local experience and discussions with reputable local repair shops. None of us has anything to gain from misrepresenting the facts.
