Getting ready to do my first oil change on my 2017 911/991 C2 .:biggrin: Can anyone recommend the best brand of oil filter, the part number and cost ?  :helpsmilie:They seem to vary in cost from $12 to $35 bucks, different brands and part numbers, on various sites, for the same brand filter ,which I find very confusing ??? Also, is it best to use Mobil 1 0-40 synthetic , or would you recommend another type & weight of oil ? I live in Florida, so Im concerned about 0-40 being to light in the hot summers we have here. Much thanks for this advice, cheers Dave :cheers:

Oil and oil filters always tend to start arguments, most of which are totally unfounded.  That said, if you are still running the factory cartridge style oil filter, I would use a Wix/NAPA Gold 57211:



Much better made than the OEM filters which still use glued on end caps that tend to leak. The Wix is embedded in plastic and has a internal support cage as well.  Readily available and most auto part stores.  Even in Florida, you should be fine with a quality full synthetic 5W-40 oil like Gibbs DT40.  Like many other shops, we are no longer fans of M1 product's.

Thanks for the info, I just can't figure out why as to quote you "Like many other shops, we are no longer fans of M1 product's "   :blink: I always thought Mobil 1 was fine , and why do Porsche still use it for a factory fill ? Could please elaborate on why Mobil 1 is not that good ? Also are you sure that " Wix/NAPA Gold 57211" oil filter will fit a 2017 911/991 ?  I tried to find it on the NAPA site and it appears not to fit ? Please advise ? 



Thanks a lot, and I will be getting that Wix filter as you suggest if that number is correct ?   Thank U ! :biggrin:

I was all set to do it myself on my "new 2017 911/991 gen 2 " , that just turned 3,000 miles. Got all the stuff (oil filter & O ring, new plastic drain plug, and even the special tool to remove and install the new plastic drain plug, THEN I remembered the warranty, and re-setting the on board computer display ! eek.gif 
Hence, fearing that issue, I took it to my local Independant Porsche tech here in Daytona, where I use to take my old 996, where I could get a receipt at least. He is very good, and I watched him do it, but realizing I could have easily done it too. 

So my questions are : #1. How does Porsche inc feel about the owner who wants to change his own oil, when the car is still under warranty ? I mean, how can you prove it was done ? At least my indy, gave me a dated receipt, showing he was a bonafide Porsche tech, and listed the Mobil 1 0-40 , and Porsche (Mahl) OEM filter .

#2. How does one re-set the onboard computer, ref the "oil change" ? 
If something were to happen to the motor, when it's still under warranty, and the owner has been doing all the oil changes, would that not void the warranty ?

Also my indy said the Mobil 1 0-40 is ok , but he recommends either the Mobil 1 5W-40 or "LIQUI MOLY" SAE 5W-40 (German oil) particularly here in Florida ! He also didn't like the plastic oil pan (with no cooling fins to dissipate heat) and this new style 1 1/2 turn plastic drain plug, apparently it's also used on newer VW's and Audi's confused.gif Then there is the air filter issue, were you have to remove the entire rear bumper ! eek.gif
It's quite apparent, that Stuttgart does not want us working on our own cars anymore, and what's with all this plastic stuff soapbox.gif Any advice/input on the latter is much appreciated thumbup.gif Thanks Dave C ( Ponce inlet Florida)

In general, dealers will accept your receipts as proof of service, so keep meticulous records.


Resetting the service alert requires a Porsche specific scan tool such as the PIWIS or Durametric system.


Plastic pans and cam covers are becoming more common with the newer cars.  Your oil is cooled by a separate cooler, so the plastic pan should not bother anything.


Oil is a "hot button" topic, so while I do agree with the suggested 5W-40 weight, I would choose Joe Gibbs DT 40 due to its high levels of ZDDP.
