Porsche's original reccomendation for the Boxster S 3.2L was 10W40/15W40/15W50 for temperatures higher than 50F. However they've since revised their recommendation to 0W40.

I would say you're probably OK to use it, but 0W40 is preferable.

I agree with John V. Porsche's only 50 weight approved oil is Mobil One's 5W50 right now.

How old is the oil in the garage?

It's totally fine for 50°F + driving.

The only issue you're likely to see is a slightly reduced Range (MPG).

I know Porsche now use 0W40 Oil for year round use. If you only drive your Box in warm weather I guess you're O.K. because the 15W will never be factor. But the higher the Viscosity the more resistance to flow the oil will have and the more wear at every start-up you will have after the car has been sitting for a couple of hours and the oil has all run back down into the pan.

Variable valve timing systems depend on oil pressure for correct activation. If the pressure or flow is too low the system will not function as designed.

If I lived in where you do, I would only use this oil in Summer. Perhaps you could use it from May-Oct and switch to 0-40W?

I have used 15W-50 for the 9 years I have owned my Boxstir.

http://www.renntech.org/forums/index.php?showtopic=9454&hl=unapproved

I used the EP flavor for the last oil change because the regular 15W-50 had been discontinued. But since then Mobil has brought it back to the market.

While I may not be going to Porsche heaven, my 1997 runs fine.

If you don't want it send it to me.....

As I understand it, synthetic oil is derived from foodstuffs.

So, maybe the one on the left is the pick?
