So Edge 10w60 with a 30min warm up before giving it a squirt, or Edge 0w40 with oil cooler if your thrashing it for a long duration, what if you only boost off the line at a set of lights once in a blue moon, would Edge 0w40 be fine to use? And for everyday driving? Also, I ended up buying Transmax Z for the t56, I had to buy 2x4Lts bottle at $75 each as they didn't have any 1Lt or 2Lt bottle at any of the local ripco or superheap, so my question is, what sort of shelf life does an open bottle of this stuff last for, I do around 10k km a year in the car so I probably won't need to change it for 2 or so years.
