			Everyone of our customers that have tried anything other than the OEM (a full synthetic) gear oil, and that is just about all of the aftermarket stuff out there, have all ended up draining it out and going back the the OEM product due to poor shifting, noise, etc. after only a short time.

Hello JFP, 
How often do you recommend to change the gear oil?

				Once again we meet.
			 
			 
			
		
		
		
			And once again I will take your advice. 
 Is there an online source I can order it, or just go to the nearest dealership? 
By the way, I got the Wix 51042 oil filter as you recommended, looks a little bit small for a 3.2 engine.

Depends upon the car and how it is used (or abused).  Usually, changing it between 35 and 45K miles seems a safe bet for a daily driver (yes, I know that is well short of the recommended distance).  Like all lubricants, the OEM full synthetic gear oil will break down with both miles and time, so a garage queen that does not see a lot of miles; I would drain it around every 5-6 years, just to be safe.

A couple of decent online sources can be found if you do a search, but they are often no better than your local dealer.  You could also give Sunset Porsche in Beaverton, OR a call ((800) 346-0182), they price very aggressively and offer quick service as well.
 
As for the Wix 51042, this is one example of where size can be deceiving.  It is the filter designed for the 6 and 7 liter LS engines series in Corvettes. That unit can flow over 11 gallons of oil a min., well beyond what your engine can pump.  If you cut one open and measure the total surface area of the media, you just might be surprised how much is in there.  It is a great filter, usually also at a great price......

				thanks JFP
			 
			 
			
		
		
		
			It is a pleasure reading your posts. 
I appreciate your patients and your detailed answers. 
That’s what happens when the last time you replaced an oil filter was 15 years ago

			Looks like it; the Suncoast group have been pretty good, but give Sunset a phone call (they currently do not have a parts website), they are often cheaper, even including the freight.  I get a lot of stuff from them, and have used them for many years.

				Ordered the oil today.
			 
			 
			
		
		
		
			The guy was very kind and helpful. 
The price was 24$ for the liter (4$ cheaper then Suncoast) and will be shipped to me today. 
I told them JFP sent me so they gave me another 50% discount 
 
LOL………. just kidding   
Any way, I’m definably going to check them out every  time before buying an OEM part.
 
Thanks JFP.

If it makes you feel any better, we recently serviced the gear box in a Nissan, with $126 of a GL-4 full synthetic gear oil.  $20+ per quart is not uncommon for these lubricants.......

				Porsche gear oil....
			 
			 
			
		
		
		
			...is expensive but not really that bad. 
 
Considering if you were to fill with 3 liters of synthetic gear oil, you'd find it ranging from $14 to $20 (valvoline to Royal Purple or Redline). 
 
Given the reports that some owners have not been happy with the aftermarket products, the OEM stuff is not bad, say and extra $15 to $30 for the whole job...not much for something done so infrequently.
