Hello dear oldtimer fan community, am new here in the forum and new in possession is also my Oltimer Porsche 911S, BJ 71, a dream in white. The question is now which engine oil is the best with such a vehicle. I also heard this the modern Vollsyn. Oils in these engines are not really cheap. Of course the car will need a little bit of oil but I am an opponent of this additive. So can someone give me a tip with which oil I should fill my little oldi and which Zu I’m happy to hear your constructive suggestions. Thank you very much.
