I am currently running Millers CFS 10w60 but as i'm having to drop the oil to replace a couple of pipes, the one in the rear arch to the tank is corroded and leaking, i'm think of going up to the 15w to elimate any small leaks especially around the turbo seals. Will the 15w be suitable for a 3.6 for fast road and some track use?
