Hi guys ,
I am getting ready for my first engine oil change, I would like to hear from you what type of oil and grade you are using , I live in an area where the climate is quite mild, around 10 degrees in winter and 30/35 in summer
Thanks

The first thing is to find an oil that gives you the pressure and temperatures you want, some of that will be due to the weight, and some the quality of the oil. Depending on the condition of the engine and cooling system each car will be slightly different.
Obviously there is a compromise between protection on track under severe conditions and "cold start" (even 35 centigrade is cold for oil) protection - "normally" most of the wear on engines does occur during cold start. For a normal "shopping car" the cold start wear is the dominant factor and oils are specified by manufacturers accordingly (usually 30 or 40 weight), this is not so much the case for a track car that spends hours running at 110c oil temps which is where 50 weight oils come into play.

The most popular three options are below:
1. If you don't mind spending money: Brad Penn
2. Equally as good but a little cheaper and you can pick it up at your local Autozone: Valvoline VR1
3. If you are cheap but a still good alternative that you can buy at Walmart: Shell Rotella
I personally have used Valvoline VR1 on all of the air cooled 911's I have owned
