Last year I ran my TR with 20% Blue Thunder and had no problems with lubricant. YES.......its true that it turns the inside of your engine block blue, but I haven't seen any ill results from that.

This year I made the swith to Trinity's Platinum 30% which is only 9% lubricant, so I doubt thats what you would want to run.

As for your WOT running. Yes, most of us track guys only get to do WOT on the straight, but we have to do WOT quite a bit during final break in so that we can see how well the car is doing on top end and what the engine sounds like on the top. So while its not reccomended that you do constant WOT, it shouldn't be a major factor in your high temp.
