M1 5w-30, Water temp is OK, 200-210 I'm running green coolant for now. I have water wetter ready to swap it out with but I figured I would just keep the green stuff in there until I take it to my first SCCA school. The temp seemed to peak a little over 300, and would come down a little under 300 if I short shifted. Maybe swapping the coolant for water wetter will be enough? Thanks.
