Anyone know if I should be using a different grade since mine has clocked 163000km's?


i went to winton raceway on friday with my eg which has about the same amount of km's on it as your s2k and i tried out Nulon's 15w50 full synthetic oil, and having been using 10w60 edge sport for the last 15,000km, i felt the difference from first start up. the motor felt alot smoother, oil temps never got above average, holds pressure nicely and after 30 laps not a single bit was burnt off. i have started putting this oil into customers cars as well and they are all coming back with massive smiles on their faces. 5w-30 is definitely too thin for a motor that has clocked over 100,000km. try out the Nulon oil and let me know how you go with it
