Hi
I'm going to change oil, and I have problems finding a place where I can buy Mobil 1 5W40.
I have found Mobil Synt S 5W40 and it is on Porsche's list of approved oil, but I can't find out if it is bad choice compared to Mobil 1?
Any insight?

Not to long ago there was a thread on motor oil choices.It was pretty good.Ofcourse there was no agreament on the best oil to use.FWIW As far north as you are 0W40 sounds like a good choice.Unless you plan to run one oil in summer and another in winter.

I have now read the other post about oil (sorry for not doing that first!).
-> Eggplant: Why do you recommend 0W40 when you in the other post state that you have noticed lower oil pressure using 0W40 and that you will change to 5W50 next time
I think I will go for Mobil One 5W50 as this seems to be the safe bet.
I only drive in the summer which means in temperatures between 5-30 celcius.
My car has 107 000 km (67000 miles) on the clock.
Thanks for your input.

I actually have 5W-50 now but am refilling with 0W-40 since I can't get the 5W-50 easily in the US. But I did notice that oil consumption was a bit higher with the 0W40 than the 5W-50. I watch oil consumption regularly.

If you are only driving during swedish summer then the 5W-50 or 15W-50 is fine. I've noticed a change in engine sloshing ( that noise of oil flow) with 15W-50 vs 0W40.
