Another oil question
I know there are a million threads on this, but I read lots of discrepancies in information. This is my first oil change with my Porsche so I want to make sure I start out on the right track.
I have read a lot about the Mobil 1 Truck oil, but then I just found an article saying NOT to get it since it was reformulated in 2008...
I am trying to decide between:
Total Quartz 9000 5W-40 @$5.00/quart (Porsche approved... but for what?)
Mobil 1 Turbo Diesel Truck (5W-40) @$4.40/quart
I would also have Mobil 1 0W-40 European on here but my local Wal-Marts don't stock the 5 quart jugs.
Am I being way too **** about this or is there really an appreciable difference between these oils? Any feedback would be appreciated.
Thank you!

Oh boy! Not again!
I heard good things about the Total, but the Mobil 1 0w40 is easier to get around here. That's what I put in mine.
Honestly, It probably makes no difference for a street car, so stop reading all that crap on Rennlist!
On the track, on a hot summer day, it is another story! Then you can pick your brain all you want. You'll probably have to put in some much thicker oil like the Brad Penn, and should invest in a secondary oil cooler anyways.
Good luck!

Wow, almost unanimous! It looks like I need to find a Wal-Mart with the 0W-40... I checked all three near me and they only sell it in the quart bottles. I know I am being cheap but I have already blown my car budget for the year, and next year too
If I can't find it, then I think I have a lead on the Brad Penn oil.
Thank you all for the replies and your patience.

I blended the Mobil 0W40 with the Mobil 20W50. Their tech people didn't seem to have a problem with that and the wear additive levels are similar on both those oils with the 20W50 having slightly higher levels. We have higher temperature extremes here even in an abbreviated driving season. I figured the high temp and low temp viscosity will be more to my liking. According to the Mobil specs I don't see a problem with the 5W40 Mobil Diesel oil either.

Hi
My car has covered the last 125k miles (7 years, at 185k now) on castrol semi synth 10w40 changed every 10k. It has never had the engine touched and it does not smoke, rattle or exhibit any valve noise. I have heard that thinner weights can make oil leaks worse. Regular oil and filter changes seem to be more important than exactly what you put in.

JMO: After the screaming deal you got on the car now is NOT the time to try to economize. Regular (3000 mile) changes of the less expensive (than Mobil One) Brad Penn oil will pay off in huge dividends down the road if you plan to keep the car.
