Hi,
I have 2002 a6 130 tdi and when I last bought oil for the service from Audi they sold me 5w30 castrol slx 3 which they said superceded slx 2 0w30.I am still not sure about this oil , slx 3, My car was on longlife service, but I have changed to 10,000 miles fixed service because of the type of driving I do, however, I still put in longlife oil as it is better than normal oil.
The engine has done 98,000 miles and I need to know wether or not it is safe to use a engine flush as it is due for service, also will it be better to revert back to slx 2 , that is if I can buy it as Audi no longer sell it.:confused:
