That’s somewhat farcical actually. It’s true it will run hotter, but not materially unless there is a substantial increase in viscosity and that’s assuming the clearances have been revised for the lower viscosity. Operating conditions such as track use could also impact this. So, there’s an equilibrium point. From what I’m being told 75w110 is the sweet spot. Mine may see track time if my 8 goes down, but I’ll probably not go higher than 75w90 and likely just 75w85. Same for the front.
