Transaxle oil Castrol synthetic TAF-21
I have a large container of Porsche Castrol synthetic transaxle oil 75w90 GL-4 TAF-21. Porsche part Nr. N 052 911 C0. Does anyone know if this good for use in the turbo trans or differential? Are there special characteristics of the TAF-21? I think it may be a special formula that shifts smoother at low temperatures(?)
thanks
