Greetings
Has anyone run Vertex 75w90 in their classic dccd?
I've recently had my v3 sti-ra serviced with this and not sure about the results.
It feels like dccd is on orange all the time.
Lots of noise coming from the centre diff under low load around town but only once it warms up
I'm tempted to drain it out and go back to some standard oil but it cost me a bit... 😕
Interested if anyone else has a similar experience
