So I'm having the tct problem and im changing the oil but not sure to what... any input would be good.. Thinking about high mileage castrol the green bottle it's a synthetic blend... Some are saying Mobil 1 is real thin and not good for the tct....

 

Get a Billman TCT, problem solved.

Ok good advice on the tct but what about what oil to use????dont want synthetic no more it's to thin... What is good convential oil???

 

Ive used castro for all my cars even s2 no issue, plan to use mobil 1 turbo diesel now, since i heard has good amount of additives to protect wear, guess we will see when i send used oils to the lab to compare

 

How would the turbo diesel oil work in the s2... First time hearing about that.... And is the car boosted???

 

Hey Miguel would u agree to use castrol high mileage in the s2 think it would be a good idea... I have used castrol before, really good oil

 

Mobil 1 is fine oil, and not the cause of your tct problems. If you want to change though I recommend Rotella t6 5w40.

 

So why did the tct go bad???? Low oil level ???

 

castrol high mileage. 215k on the clock to prove it.

 

It went bad because it was designed poorly. However, many people say that they first got the noise when switching to Mobile 1. But I have seen way too many engines torn down that were using Mobil 1 or Amsoil that look like they are brand new on the inside. I would change to a superior TCT and keep using a synthetic.
