Not sure how you'll protect against banging off the rev limiter, that's just negligent since it's pretty rough on a stock tune and how it just bucks you hard if you run into it. If you tuned it for a soft limiter that just hangs at 7400 rpm that's different.

A "sticky" viscous oil additive would probably ruin your engine on a freezing cold start.


Having an oil that can deal with temperature extremes are more important, below freezing and in overheating conditions (summer track days). If you're in Chicago, during fall and winter months you should be running 0w-20 for easy cold starts, and replacing it a couple times through the months as the oil gets diluted with fuel from cold starts / idle.
During summer months in the Southeast I run 0w30 with a quart of 0w40 mixed in, and I think its good for hot days. I will be switching back to 0w20 in November when we start getting mornings below 50 degrees F.

I wouldn't buy into ordering in specialty oils. I've spent a lot of time on BITOG forums and seen good results from pretty much every oil analysis on modern synthetics. Whatever has API Certification label on the shelf at walmart is good, save the money and just change your oil often.

Be aware that thicker oil runs hotter, is less efficient. If you're tracking during summer and running some kind of thick race oil, get an oil cooler.
