Finished the 2018 season using Red Line 5-20 synthetic race oil. There was very, very little additive separation when I pulled the pan. What you see in a cold oil pan...full of cold oil...isn't an indicator of what's happening when the oil is hot and flowing.
The oil deal is a bigger issue for Stockers that have to use a flat tappet camshaft combined with high spring pressures and aggressive lobe profiles. For those not running under that set of rule constraints, there are dozens of oils that will work well.
Excessive additive precipitation is something to consider when choosing an oil filter. Those dots can be connected accordingly.
