Mobil 1 0W-40 Porsche approved.

[guru944]

Guys and Gals:

Just wanted share the latest info on motor oils and what all us 4 cylinder front engine owners can use. Recently there have been many post regarding ZDDP, Oil Viscosities and what can be safe to use. Well Mobil 1 has stepped up and Porsche likes their 0W-40 Fully Synthetic Product enough to approve it for all Porsches, Old and New. It has enough Phosphorus (1000 parts per million) and Zinc (1100 parts per million) for our Engines protection.

Mobil 1 0W-40

Published in The latest issue of Excellence magazine February 2011 see pages 22,24,26. "One Porsche 944 owner" who uses 20w-50 poses a good question.

I recommend picking up this issue....

Also visit: Oils: What motor oil should I use? Which oil is best for my Porsche or aircooled engine?

Hope this post was helpful.

Grace and Peace to all.

Here we go again! I'll be a fly on the wall for this one.

Yeah 0W-40 is great for old Porsches - you don't need to change the oil as often, because it continually goes out the exhaust pipe - you just need to put another litre in every week.

Perhaps OK in a cold climate I guess.

By your/Porsche's logic, even a 356 can use a 40 oil? Hmm - don't think that would be too good.

Seriously though, most track cars seem to run at least a 50 or 60 weight (at least here in Oz).

Mobil 1 also has a 5w-50 Porsche Approved for the Special vehicles that require this.

Be Blessed.....

our dealership here recommends mobil 1 15w50. its all dependent on your area of country and its weather. though a few of the technicians at the dealership highly recommend brad penn and royal purple of the same weight.

[redranger]

I'd stay away from the 15w50 in cooler climates. I used it in my 968 and as the weather turned colder, a ticking noise developed. Went to 0w40 and it stopped almost immediately.

LOL __+ 1 Agree 100% with you,this is what I use in my (944-968) for the last 28 years & I'll say if it work for thousands of miles stick with it .Most of our cars are past twenty years old now, not some super duper new car with out of this world technical motor design , new Porsche technicians woudn't even know what the inside of 944-968 motor look like even less work on them.So why reinvent the wheel,change your oil & filter every 4k miles & bingo your motor will survive many many miles. My contribution to this nonsense oil thread

I like the Mobil 1 0w-40. The bottom line is, use what you are comfortable with and like. The real benefit of this discussion coming up is it gives newbies some information to help them research what they will use, and get an idea of the general opinions of the different oils that are out there.

The problem with those endless oil thread once started is they don't really benefit (the newbies )on the contrary the get so confuse they don't know if they should turn left or rigth.Do a search on different forums & you'll see what I mean.

Exactly my problem!!!

This migth help end your problem,after all Porsche did design & market your car they should know what they talking about .By the way anybody want to show me where Porsche recommend using 0w40 or 0w50 in those 20 to 25 years old 944 .

Even though the name Mobil 1 makes my skin crawl, of that list I would consider using the V-Twin only.

What Mobil and even Porsche say is approved has very little to do with our cars. Collectively they couldn't give a flying fcku about our cars.

I run a VR 25w/60 btw so I guess a 0w/40 ain't for me.

[guru944]

Pops & Ernie:

LOL, It's very important that the facts are clear and real world results are published.

I'm reprinting some collective info from other Blogs on (See Below).

Porsche C30 Motor Oil Specification.
Porsche engineering data demonstrates that Porsche C30 specification, is the very best viscosity for their engines to date.

High Performance engine that runs hotter.
Amsoil's European Formula Synthetics 5w-30 and 5w-50 meets Porsche C30 Specs.
Mobil's 5w-30 ESP, 0w-40 and 5W-50 meets the very demanding Porsche C30 spec.

The Porsche Approvals process for these engines is very demanding especially in the areas of viscosity retention and foaming controls. This of course includes the minimum HTHS vis. of 3.5cP.The most demanding job for oil in a SI (spark ignition) engine is the oil film strength for the crankshaft. which receives the brunt of the explosions from the cylinders.
Everything in engineering is a trade-off. Porsche did the trade off of high oil temperatures, extended drains, deposit control and certain tolerance characteristics, and came up with the C30 Spec...
No SAE30 lubricants have been Approved for Porsche designed engines since 1999.
Porsche did in fact use SAE30 lubricants as a factory fill. A 10W-30 was used in the '91 (or so) 928GT (the first car to receive a synthetic engine lubricant as a Factory Fill).
The 2004 911 turbo, the factory initially recommended Mobil 1 Synthetic 0W-40, but lately because of intermediate shaft issues, many are going to either Mobil 1 5W-40 or 5W-50.
Porsche engineers are under the same EPA constraints as any car manufacturer, so their oil recommendations for US cars is entirely based upon what is mechanically best for the car.
Using an Approved viscosity (especially via TSBs) is very important. And yes the Porsche Engineers know best, they are the expert authority.
If Porsche uses low tension rings like VW, dilution and slug could be a bigger issue than in other motors (40w holds up against fuel dilution longer than at 30w since it starts out thicker).

Why does the Veyron use 5w30?
High performance European cars tend to use 40 weights and thicker (Ferrari, Lambo, Porsche), so you might ask why the Veyron goes against this?

Because 30wt oils aren't unusual for Volkswagen AG products.
5w-30 is to Europe what 5w-20 is the the USA.
You could say the same for Australia.

5w30 is about the thinnest grade I have come across over as std recommendation by OEM's.

People who think they know more than the Car Manufacturer's engineers and designers make me laugh ! Especially Porsche, THEY KNOW what they are doing. Engine tolerances and design mean more than just oil temperature !

Argument from authority - Wikipedia, the free encyclopedia


Argument from authority (also known as appeal to authority) is a fallacy of defective induction, where it is argued that a statement is correct because the statement is made by a person or source that is commonly regarded as authoritative. The most general structure of this argument is:

1. Source A says that p is true.
2. Source A is authoritative.
3. Therefore, p is true.

This is a fallacy because the truth or falsity of a claim is not related to the authority of the claimant, and because the premises can be true, and the conclusion false (an authoritative claim can turn out to be false). It is also known as argumentum ad verecundiam (Latin: argument to respect) or ipse dixit (Latin: he himself said it).

So basically 10w30 or 40 will do just fine in a Southern New England climate according that. Doesn't get more simple than that.

[TibetanT]

First and foremost, I believe the article, or rather the technicle article, questions the use of additives in oil. To which Bruce Anderson cautions against its use.

Second, I also believe that there is a mis-print stated 5W50 Mobil 1 has 1000ppm, when in fact checking the Mobil 1 website you will find that 15W50 Mobil 1 synthetic is the oil they recommend.

Certainly when it comes to our 944/951 cars, it depends on the use: track versus daily driver, that should be taken into consideration.

Fact is, I have always used Mobil 1 15W-50 Synthetic in my 1987 944 from day 1. Until of course I moved to the Inland Northwest where temperatures can plummet to below zero (-23 degrees just a week or so ago). When those temps come, or rather before Winter comes upon us here, I always change to Mobil 1 5W-30 for the colder season. Of course, I don't drive my car regularly during the Winter months due to salt and other corrosives being placed on our local roads.

Just my .02 cents and certainly...I am no expert "oil guy" but know of a few whom are.

Be careful and change your oil regularly, as some above have stated, that, my friends is the best advise. (just so you all know, my oil gets changed every three thousand miles...yes, it gets expensive...but I sleep better at night.)

Cheers

I'm also giving you real world results ,the difference is that it come from Porsche ownership since 1974 without having to open up any of their motors on any of them.Like I mention before got my 83 -944 with 6K miles on it & never once did it let me down in 26 years .If that not real world results what is it.You can link all the articles possible about oil research & what's good or not for ours cars, I don't really care ,what I care about is having a Porsche that I can drive & enjoy anytime I feel like it. And this was achieve by following my owner manual specs for all liquid including oil & dropping the oil and changing filter every 4k miles.For me those are real world facts.

LOL... Congrats on the 968. Please post some pics.

PM me. When you get a chance...

Grace and Peace.

[ernie9944]

Thank's for the congrats,I don't need to post pics every thing you want to know about my past & new ride is ( under my garage __Dream 93-968 or___ Old faithful 83-944 NA.)

"People who think they know more than the Car Manufacturer's engineers and designers make me laugh ! Especially Porsche, THEY KNOW what they are doing. Engine tolerances and design mean more than just oil temperature !"

At what point do you think the Porsche engineers ever considered our cars with larger tolerances and flat tappet motors when they make these announcements? Would you like some thinking music while we wait? By all means keep using 0w/40. I suppose if I were to be living in conditions that got below -10c I'd consider something lighter than a 20w/50...or if I was trying to eek out extra gas mileage...but no, I want protection for all those expensive metal pieces inside the engine that are actually all trying to smash into each other and get out of the block. The oil is your last protection against this. It's the last bearing. Oil is not just a lubricant. If I'm racing on the track or even in heavy stop start traffic, I want an oil that is not going to thin out to a consistency not much higher than water.

As for 'real world' experiences try looking in the best thread on the topic which is right here in Pelican. Real world experts who work on these motors daily.
Ultimate Motor Oil Thread or Why we hate CJ4/SM oils

As for the Porsche engineers being the ultimate experts...well go and speak to all the people with failed Boxter and 996 motors and get their opinions.
Even further back through the 1990's. Talk to the Mobil 1 authorised repair shops that found accelerated wear and engine failures when Mobil had neglected to mention that
they'd removed a high % of ZDDP from their product without telling anyone. They switched back to VR1 and presto, no problems.

Peace and Brown Rice to you too.....
