I personally think the Water Wetter will provide more cooling than the new oil.

Depending on the UOA from the GC I'm currently using I'll give the 5w-40 a try. Then we'll have some notes to compare on the three viscosities.

Great! And let's go to the same track day and record temp on the same session. But to be fair, you should run Water Wetter as well.
