A friend of mine has been taking his 996 to a local shop for oil changes. So out of curiousity I called the guy and he told me that if I bring my own oil, he will change it for $35. What confused me is he said it is fairly simple, but there are two drain areas? Is that true. He has been in business for over 25yrs. What do you think? Try :) it?

Also, are there any codes that need to be reset after an oil, air filter change? Thanks!

Porsche now says Mobil 1 0W-40 or Castrol 5W-50. My dealer in San Jose uses both depending on what they have on hand.

I still use Mobil 1 15W-50 on my 1997 Boxster. We must have done a 100 oil changes over the years at our work on cars days and people bring all kinds of different oils, brands and weights. If there is a difference for a car in San Jose then it escapes me. We put in whatever they bring, including non Mobil and non Castrol.

When Mobil pays me like they do Porsche for their sticker stuck on my lid then I will promote their brand. ;)

No one has brought them to out work on cars day. There is an oil message board that is very good. http://theoildrop.server101.com/ubb/ultimatebb.php When I searched on TWS Motorsport they said it was not for retail sales, only dealers. But when Mobil 1 0W-40 first came out Mobil said the same thing, then it started to show up in retail stores. But TWS is not on the approved list and there is no 60 weight oil on the the list.

Castrol Formula RS Power and Protection 0W-40 is on the approved list. I am on the UK Boxster board and they use it in the UK - I did not know we had it in the US.

Castrol Formula RS Race and Track 5W-40 is also approved, but I do not know if we have it in the US.

The 8 page world-wide list of approved oils is in the TSB section.

Castrol Official german website


"Leistungsklassen: API SJ/CF, ACEA A3/B4, Spezialfreigaben von Porsche und BMW - Exklusivfreigabe für BMW M3/M5 Motoren."

short in english: "exclusive approved for Porsche and BMW engines"

you are right, the TWS 10W-60 is not for retails, you can get it from BMW and motorsport partners here in Germany.
