I tried to search for the answer to this question but came up empty.

My 997.1 didn't come with a owner's manual (though I have one ordered from suncoast). I was able to download one but it is from 2009.

In the manual I downloaded, there is a picture of a telescoping filler tube for oil; I don't have this. Just wanted to confirm that this was a change for 997.2?

Here is the illustration from the owners manual:

Yes the 997.1 is cradled in a notch. Pull up on it gently to raise it and add oil.

Thanks DC911S - appreciate the info.

Both models have a filler tube. You pull up on the filler tube and add oil. The 997.1 does not have the telescoping piece on the end though. Here's the image from the 997-1 manual. That must be a 997-2 feature.

Also, when replacing the cap be careful not to cross-thread and that is tightened securely - caps not tightly sealed may cause a CEL.

Thanks guys

My paper based owners manual from suncoast should come early next week so I will be all set.

patriot993 - I thought I had a fairly unique combo - 2007 Targa4S, midnight blue with beige sand full leather. I see you have the same (almost anyway). At least you aren't in Virginia!

RussV60 - our combo is pretty unique...I bet there are only a handful in our color combo. Truth be told, would rather have yours as mine is not an S and doesn't have full leather....but still a blast! And only 13K miles so far...though I am working on changing that

Had mine since end of November. Had exactly 18K on it when I bought it. New tires and 20K service already done. Purely luck that I stumbled across it on consignment at a European car dealership. Had barely been driven 3K miles in the last 3 years. I use it as a daily driver and I couldn't be happier. Odd about the oil filler - mine has the telescoping tube. It was down 2 blocks when I bought it and never moved but I decided to add a block (0.3 l) before a trip and it went up 1 block and hasn't moved since. I wasn't too keen on the auto oil level but it does seem to work ok. I also downloaded the 2009 manual - I think it the same as my paper manual. haven't noticed any real differences. maybe I need to look closer.

One other question - how have your TPMS sensors held up? One was out when I bought it and it was replaced by the dealer and now I have lost 2 others. My research says this is actually good life in terms of years but since the miles were low they should have lasted this long. I probably should have had all 4 replaced at the time - it looks like I will have to bite the bullet on it now. 2007 was the first year they were mandatory and they weren't all that reliable.

Mine always read three pounds low in my 2007 C4S.

Re: TPMS -- My car is a 2008 C2S Cab manufactured August 2007. I purchased it in September 2012, and when I replaced the rear tires in December 2012, I replaced all 4 TPMS's with new OEM units as preventative maintenance. I was ignorant of the TPMS market and probably paid too much, but I do like to maintain factory-fresh stock condition so I have minimal problems (i.e., all systems have been specifically engineered to work together).

I also bought a nice Longacre digital pressure gauge as Longacre's headquarters is literally just around the corner from my plant and at least one executive has bought products from us. Knowing the high quality of this gauge, knowing that it was freshly calibrated right before I picked it up, and knowing that I can get it recalibrated at any time, I have high confidence in its accuracy to the fraction of a psi.

According to my Longacre gauge, every single one of my OEM TPMS units consistently reads 2 pounds too low.

As a related matter, my tire installer and alignment specialist interviewed me to some detail about my weight, driving habits, normal cargo loads, etc., etc., and recommended that I use 35# in the fronts and 41# in the rears unless I was going on a road trip with my wife (then use 37# and 44# respectively). This is slightly different than Porsche calls out for my car -- they recommend 33# and 39# with no load but me. After nearly 10,000 miles since new, and with my careful monitoring of the tire pressures my MPSS's have been wearing very consistently and minimally. I'm impressed with the alignment company's computer program as well as their alignment!

RussV60

I run my tires right at the recommended 37 front and 44 rear. I check them with 2 different gauges and get the same result. The TPMS can sometimes show 2 low but most of the time are right on. I have read a lot of blogs that you shouldn't use the TPMS to set accurate pressure.

Wayne Smith

My tire specialist suggested 42 cold in the back and 36 in the front. But I was getting an 8 to 10 psi increase when driving the twisties which resulted in some major grief from other Forum members when this showed in conjunction with the 50,000 miles on my odometer photo!

But I had worn the previous tires badly on the inside so I followed his advice with the higher pressure. No wear for the first 5K miles this way. I dropped the pressure. No adverse wear now for the 16K miles since the alignment in January. I figure the very minor alignment alterations were the key, not the pressure.

This recommendation is for a fully loaded car at max speed. Way too harsh for the street and poor grip for the street or track. I run 32 - 37 cold for street and a bit higher hot for track. Read the adjacent label on the door sill and it says to consult your manual where you'll see lower pressure recommendations.
