I see this is an old post ... but i am wondering if you can help oil man.
I have a UK Turbo (99) and i am looking to replace the diff and gearbox oil.
The car has sit for around 2.5 years before i bought it, the car itself is spot on mechanical wise, the gearbox & diff feel good no knocks or bangs etc.
But with it sitting i want to change the oil in both.
Do you have any suggestions as when it comes to oil i have no idea.
thanks
