I was waiting for you to show up in an oil thread...you sniff these out in amazing time normally. I was not saying one was better than the other but waqs just sayin gwhat Porsche has said about the proper oil for the car. My shop however says here in Florida and for DE's they recomend 15w-50 and have not had any vario-cam issues. Which on eis correct...Porsche or the independant shop?

 

No I'm the guy who came to bat for you when folks said you were a little "misguided"(my word not theirs) I'm better now thanks. Happy driving.

 

Independent shop. They can do what is right, Porsche has to say and do what is necessary for their cars to meet government mandates. As well as to reap the benefits of the substantial contributions Exxon makes to their balance sheet.

 

Both the indy shop and my dealer both use Mobil 1 so I do not see how the dealer is help Exxon/Mobil over the indy shop. The indy shop will use 0-40 but recomends 15w-50 as long as you are not taking a trip to the north in the winter. Other Porsche dealer acorss town I believe uses Castrol Syntec 5w-50 on their BMW's and Porsche cars.

 

Just had the same experience at Tech. Dimensions in Jacksonville; they put in Mobil 1 15-50, said it's much better for warm climates, and they have a great reputation. Don't know if it has anything to do with the viscosity but the idiot oil pressure guage seems to have a lot more (and I hope better) variabilty now - before it was always either 4 or 5.

 

The water temp gauge is not real accurate, tending to go to 12 o'clock and keep everbody happy. The oil pressure gauge is not an "idiot" gauge. If you are saying that before you spent more time w the gauge registering full pressure then now, I fail to see why this is a good thing. Personally I doubt that is really the case; probably just your imagination. If however this is true, ie you are running at lower pressures under certain conditions, or it is taking longer to reach full pressure on start up, then I would demand they refill your car w factory recommended visc. oil asap.

 

Hey, I respect and thank you for your answer. My 'problem' with the guage is that for the better part of 3 years the guage was always at 5 and would fall back to about 4 when the engine was warm and I was decelerating. I asked several times at a couple of dealerships if this was normal and the answer was always "don't worry about it; if there's a problem the warning light will come on." In the old days with a real guage you knew what range you should be experiencing.

 

Boy, I cringed when I read this original post... knowing what would happen. The forum did not dissapoint.

My 997.2 came with a quart of Mobil 0w40 and a cotton towel in a ziploc bag in the front trunk. I'd intended to use that anyway.. got a 6 pack sitting on my garage shelf from my other car (a VW New Beetle). I can only recommend you just stick with whats on the list in the manual and what came with the car. If you want to dig down the rabbit hole and hot discussions about specialty oils and engine additives, be my guest. You won't really come to any clearer answer.. even if you think you did. ;-)

 

The gauge should not have stayed between 4-5. You should have 4-5 on startup asap. When warm 1-2 on idle. + 1 for every thousand revs. By 4-5000 you should be at max (all approx). If you were not seeing this it was the gauge, not the oil. I would use recommended oil and change it more frequently if you feel the conditions are extreme. Make sure the guys that use non rec. oil give you a written warranty should there be a problem w your motor, oil related or not. Good luck.(no sarcasm here BTW: The light he is talking about is for LOW OIL! It only comes on when your crankcase is really low, ie down several qts. If you wait for that light you will likely damage the engine for lack of oil!

 

Hello Minok. Do you suppose Ferrari guys do this?

 

Your stock oil gauge should be 4+ bar whenever your engine speed is above 3000 rpm. It should be pegged at cold startup at all engine speeds. It should never fall below 1.5 bar regardless of how hot the engine is.

As far as using the oil brand and weight that came with the car? Does that apply with tires too or have most people moved to a better tirel? It always amazes me how some are smart enough to realize that Porsche might not have put the very best tires on their cars but were right on when it came to the oil.

Thank God it is not publicly known what brand of gasoline came in the car or people would insist in only using that only brand.

 

Why don't you do something useful like explain to the guy the difference between his oil pressure gauge reading and his red low oil level indicator light?

 

Are you inviting me to correct you again? Ok.

The dealer was not referencing the oil level gauge but, in fact, the low oil pressure warning light. Maybe you were not aware of this low oil pressure warning?

Feel better?

 

The low oil pressure light is a function of low oil level as I understand it. The system will maintain proper pressure until the level drops too low. By the time the light goes on you may have waited too long and are risking engine damage. This is the idiot light being discussed.

 

Reference pg. 96 in The Manual: "if oil pressure drops abruptly and a message displays.... when engine is running...Stop..Check oil level...Add engine oil if necessary"
