No one answers a question in detail like the Macster lol.

Now Porsche has stated that when cold engine RPMs should be kept below 4200 RPMs. However this number I suspect assumes the engine is filled with an approved 0w-40, 5w-40, or 5w-50 oil. What is the RPM threshold if say one is running a 10w-40 oil? A 15w-50 oil? Or (Good grief....) a 20w-50 oil?

I might also point out the cam lobes and lifter bucket tops are splash lubricated, by oil that seeps out around the lifter bucket and the bore in which it resides.

If one strays away from an approved oil, and uses an unapproved oil, especially one with different viscosities, this splash lubrication may be compromised and the lifter bucket and cam lobe may experience marginal lubrication.


As for those who say you should use this oil or that oil, these are easy to handle. Ignore them. Use what Porsche recommends.Now Porsche has stated that when cold engine RPMs should be kept below 4200 RPMs.

porsche recommends keeping engine speed under 3000 rpm until operating temp has been reached. where is the 4200rpm figure quoted? as i'd like to read it.

as to oil choice(S) yes, listen only to porsche and pick one from the list of +/- 35 plus oil brands that they "approve". that should narrow it down for ya lol.

as to what advice or admonitions one pays attention to? i would suggest ignoring pedantic blanket statements regarding what types of oil can be safely used or not, and read from the many choices on porsche's updated list.

just because mobil oil paid to have the sticker on the backside of the engine com lid, doesn't make M1 the end all be all of oil lol

 

The question of RPMs limits when cold came up the other day on another board and I responded with the est. (working from memory) it was in the 4K to 4200 range. Like you someone called me on this stating he could not find it and even posted a link to an online copy of the owners manual for a 996/GT3. I found the info on page 53. I do not know where it is in my Turbo's manual.

Here's the link to the online manual:

The oils on the oil list are interchangeable. There are a good number as some oils are not available in all regions. Also, a number of oil makers make more than one suitable oil. Not Porsche's fault there are so many choices. God forbid there was just one or two choices, then the you know what would hit the fan as it would be assumed Porsche was just driving business to its buddies at the oil company so blessed to be the only oil on the list.

"just because mobil oil paid to have the sticker on the backside of the engine com lid, doesn't make M1 the end all be all of oil".

I come across variations of this nonsense all the time. One has to suppose Porsche stands to make more money from selling that sticker space to Mobil than it stands to lose from specifying a bad oil and having to deal with the warranty claims, the bad press, etc. Then one must also assume Mobil is stupid to pay that sticker fee and not at least get the list of oils pared down to just Mobil oils.

Geesh, you guys and your (lack of) thinking on this matter.

 

you mean under the section of "under 1000 mile break in period of the higher revving gt3"?

way to make a case there mac

break in hints for the first 1,000 miles/l,600 kilometers
The following tips will be helpful in obtaining optimum performance from your new Porsche. Despite the most modern, high-precision manufac- turing methods, it cannot be completely avoided that the moving parts have to wear in with each other. This wearing-in occurs mainly in the first
1,000 milesj1,600 km.
Therefore:
I> Preferably take longer trips.
I> Avoid frequent cold starts with short-distance
driving whenever possible.
I> Avoid full throttle starts and abrupt stops.
I> Do not exceed maximum engine speed of 4,200 rpm (revolutions per minute).


[QUOTE=Macster;4240704] The oils on the oil list are interchangeable.

gee, thanks for helping to make my point for me. sheesh.. what exactly did you glean or surmise my point might have been from my positing the myriad number of approved oil choices were listed for a reason!? namely there is plenty of approved oil! lol

[QUOTE=Macster;4240704]

how, or more importantly why!? and upon what basis should one assume that!? and would you please expound upon some other variation " of this nonsense" to help me in my determination as to whether you understand facts from nonsense at all? because right now? that's in question, as far as i'm concerned.

forgive me, but after that utterly obtuse contribution to this thread, i would suggest you be the last one to even raise the spectre of "nonsense" here, now, or at some other time! take your pick. the foregoing is just drivel. you've done better, i can assure you. but we all thankfully get a "pass" now and then.

but seriously, man.. but please... have a nice weekend. whew..

 

fwiw tim941nyc suggested to me to run rotella t6 5 /40 oil. 25$ for a gal and my lifter tick all but disappeared . my oil of choice now

 

The 4200 figure you reference is mentioned only in the context of if a GT3 fails to start after cranking, and says to keep it below 4200 for the first 5 minutes, not until "operating temperature."

And it goes without saying, but a GT3 has a different engine, so that 4200 figure probably cannot be applied to a TT. At least not as a "Porsche recommends..." blanket observation.

 

^ agree. at the very least! lol

 

Mr knowitall. A real google genius...laughable really

Just like you were a staunch advocate for "only what porcshe recommends" for tires, until you realized you were getting bent over for slavishly following their recommendations?


I posit that there has been lots of thinking on the issue. By people actually knowledgeable. And not just regurgitation of factoids from google designed to support your forgone biased conclusions.

On any number of the encyclopedic contribution you deem worthy of your expert input.

 

^ exactly. i'm like macster in that i like to type even meaninglessly lol. though i am probably a bit more embarrassed when wrong

 

So I called the shop that did the work, explained to them what I was hearing and asked them why they went with the oil they did vs. what Porsche engineers recommend, and they said that they feel the benefits gained by the extra zinc and whatever else outweighs the risk, BUT, they were willing to change the oil and filter again to the 0W-40 for me for free.

They said from now on they're going to ask people if they want what they recommend or what the manufacturer recommends. They also let me talk to the tech doing the oil change as he was doing it and he was a certified master Porsche tech and taught me a lot of cool stuff and took it for a drive to make sure everything seemed okay.

The place I went to was Moorespeed in Austin, Texas. Awesome customer service all around, they were super cool, said they respected my choice of oil, and that they were sorry for not verifying with me what they wanted.

 

^^^^^So did the noise go away?

 

I think its at least quieter. Then again I'm super paranoid and crazy, so who knows. I stood under the car with the tech and he said everything sounds fine.

 

Take it to a porsche specialist, don't get any work done just tell them you're thinking about it and what they think, etc.,

I hear rotella is supposed to quiet the typical flat6 chain chatter...

 

To the OP, you are OCD and have some self admitted anxiety and other disorders. My advice, from here on out, save yourself and others that work on your car a lot of grief. Visit only an authorized Porsche Dealership, have a senior tech work on your car under your watchful eye. Use only the latest Porsche approved, parts, lubricants etc. This way you will limit your own paranoia.

I work on similar stuff and often and for a variety of reasons there are better choices out there than what a manufacturer or factory recommends. Many times it's about doing the best for the customer and what makes him comfortable, at ease and happy. What is best for the machinery, sadly is often secondary.

 

well said. this car more than any has taught me that.
