Help choosing the proper oil for my next change

[schnellman]

I have run Mobil 1 0W40 at the Doktor's recommendation for ten years now in my '98. Others are in love with the more expensive oils and will quote all kinds of studies and reports. Porsche says to use Mobil 1 0W40 and it's worked fine for me and the last 100,000 miles. Nothing will start controversy here faster than an oil question or a tire question. I assure you, you're safe in your climate with Mobil 1 0W40. Some will say that the Mobil oil you buy at Walmart is different than that which you buy at a car parts store. I have spoken with the Mobil techs and they assure me there is no difference.
Let the feud begin!

Guy at AutoZone said the same thing which made me think, do I need to now pay $35/5 qrt jug instead of $25 ???

Only issues I have experienced with Mobil 1 0-40 is start up noise (2-3 seconds). My car has not been started for a couple weeks now so I'm going to be tightening my sittin checks when I do start it.

With my last change in july (I'm due now for change 3k miles) I started a tiny, tiny drip or 2 from the engine/Trans area. Wonder if 0-40 is to thin for 92k mile seals. Car was bone dry until that change.

Ok...I'll add this. I do not drive the track and I do notice the start-ups seems to be loud and metallic sounding. It lasts for maybe 2 seconds.

First, is that sound normal for a 1997 Boxster?
Second, can/should the oil change in weight impact that sound (as in lessening it).

Given this, is the general consensus still 0W40 synthetic?

Again and a gain, many thank to everyone here. Good peeps!
