Any experience with something like this?

I haven't had the need for a cooler yet with lots of track abuse but I am using a premium gear oil that's designed for track abuse: Millers Motorsport CRX 75W90 NT

DESCRIPTION:
Competition full synthetic transmission oil. A blend of full synthetic base oils incorporating new "Nano Technology" additive chemistry to significantly reduce internal frictional and power losses.

APPLICATION:
Use as received for the lubrication of competition transmissions and differentials which require API GL4 or GL5 performance. Suitable for use in synchromesh and sequential transmissions. Recommended for modern transmissions where full synthetic oil is specified, especially for high performance road and track day applications. For use in all dedicated track cars with synchronized transaxles, including clutch type limited slip differentials.

USER BENEFITS:
• Exceptional cold flow properties for easier gear changes.
• Fast lubrication flow to component extremes on start up.
• Very good oxidation resistance and superior thermal stability.
• Low friction/low drag formula to help reduce operating temperatures.
• High film strength for maximum component protection.
• Significantly reduces friction, temperature, wear and minimizes power loss.

I'm changing it once a year or as needed.
