All my readings have been done after driving and on flat ground. Once the guage showed 2 bars under max, took it again 1 minute later in exactly the same place and it showed full, and has done ever since. Me thinks these electronic guages are not that accurate.

I just spoke with a Porsche mechanic and he said that since I only put in .5 qt it would not be harmful tro the engine but I am going to suction out .25 qt to get it down to the top level line
I also spoke to a tech at a wheel/tire supplier and he said that he would just reapir the tire with a stem patch which is aone piece plug/patch repair that is installed from the inside and glued with 2 different glues and vulcanized. He said tha for street/de use it would be ok. I was willing to purchase 2 new tires but after speaking with him I am reconsidering. What dso you guys think?

do a search...you just opened a can of worms....there are many opinions on patching a speed rated tire...if you think you and your car are only worth the cost of a new tire be my guest....

First, the good news is tha TPMS did it's job and alerted me to a flat. The bad news is that I will now have to repalce the rear tire with a new one at just 1100 miles. My question is: Do I have to replace both rear tires since there is already wear on the good tire and the new tire will be of larger diameter and have no wear. I am concerned that not doing so could cause handling problems due to differences in grip and put excessive strain on the limited slip differential due to different tire diameters.
The other question is regarding oil. When I checked the level today, it showed no bars. I checked it several times with the same result. It was low.
I added .5 quart of oil and now it reads one bar over max level. I am perplexed by the discrepancy because according to the manual, the difference between the upper and lower levels is more than one quart and I just added .4 quart and now it reads over the max line. Is the computer reading accurate?
I assume that the oil wasn't overfilled from the factory and that during the initial 1100 mi. the car should have consumed some oil so how could addding .4 qt of oil bring the level over the max. In the worse case scenario, I am only overfilled by .4 quart. Can overfilling by .4 quart harm the engine.
Thanks,
Martin

1 tire only..
the Oil pressure needs you to warm up the car fully then stop on a level surface and try it, mine always went between the lines at 2-3 bars as long as you are in there do not add too much oil you DO NOT want to overfill it, mine never burned any oil at all
enjoy the car

Well you only had 1100 miles on the car but I don't know how good would be to change only one tire...as you said...for grip motivations and safety...but someone will definetely clear your doubt

Porsche system only works when the car is warm
