Oil for 996 turbo

[huggies]

I am getting all sorts of "advice" re what is the preferred oil to choose
I currently have Mobil SHC 10/60 in there and am due a change
I have been told MIllers is preferable
What do the experts suggest
The car has done 64k with a full service history
I would rather like to ensure long life as the car is a keeper

Whilst asking do I change the TIptronic oil and if so what is suggested
Ditto re the diff oil

Thanks for the help

My handbook is 10 years out of date of course and there is so much conflicting/confusing advice out there I was seeking input from folks like you who clearly have a deeper understanding and some knowledge of latest products
I know Hartech recommend Millers but my local indie persists with SHC for example
Plus I cannot run with OPC advice that every 2 years is OK
Sound help so thanks again

Got all that and taken on board and i will follow your advice

As a non engineer with a brain not really in tune with things scientific your advice has been invaluable

Yes I too remember all the conflicting recommendations when I ran SC's etc and tbh really don't trust Porsche OPC's at all on most things (sad but it's commercial world I guess) so thank heavens for enthusiasts

promise not to..... just like my Dad told me
thanks again

How about this for a brilliant response (and within 2 hours!) from OPIE oils????????




We would use a 5w-40 synthetic and you will find those through the link below.

http://www.opieoils.co.uk/c-656-5w-40.aspx

Out of those, the best ones are the Fuchs/Silkolene Pro S, Millers CFS/CFS NT, Motul Sport/300V, Red Line and Gulf Competition. The Motul 8100 X-Cess, Millers XF Longlife, Castrol Edge/Magnatec, Fuchs GT1 XTL/Supersyn, Shell Helix and Mobil Super 3000 are good, cheaper alternatives.

As you need about 9L, with most of those oils the order would be over £60, so delivery would be free.



I'll choose to go with that advice if thats OK

Thanks and I trust Mike st classic and sports car
Like you I like to do some diy hence the question which has been answered superbly

Blimey impressive mileages......in fact amazing

I agree on regular changes the wisdom i am going to run with is 5W-40 as it grants some extra start up protection as the engine ages i think.I am going with Fuchs/Silkolene on OPIE's advice whom I have been hugely impressed with

I looked at the workshop manual re the tip ATF as a DiY job.......... basically suck it out and carefully and slowly drip it in as there is a baffle.Is there more to it than that? I guess of course swap the filter also
The Porsche view is 96k miles but I wanted to do it before that based on age

Very interesting to hear from you and thanks

Yup can't argue looks like an experts job to change the Tip ATF so off to my local indie

The 2 diifs I guess are straightforward certainly the w/shop manual seems to say so???

This thread has taught me a great deal so thanks to you all
