| As WJB says, if you're racing don't put anything but water in your radiator. The rules are VERY clear. The incident at Snetterton is not the only one and since no competitive advantage can be gained by using antifreeze, you'd have to be very daft to do it. If I'd crash due to someone running additives, I'd be seriously hacked off!
For trackdays you can run whatever you'd normally run on the road. |
