A friend of mine has a 2000 GT with leaking valve guides. It has been recommended that he use high mileage oil to at least remmedy the situation.
Will high mileage oil help at all? Also, our local auto parts stores dont carry high mileage oil in the recommended 5w20. What other weights can be use in these engines?
thanks
