Hey Geforce, thanks for the compliment got a lot of good feedback from that setup. Can be anything you want, just a starting point as you are likely to go around 500 now with higher temperatures. During Euros Kyosho drivers ran around 500cst Kyosho oils, Kyosho oils are one of the most consistent out there if you tune a lot using oil then it's a good move to use their oils, if not then stay with whatever brand you have
