Outstanding oil...for those that want the best. You probably already know, but Red Line is a Grp V, ester based oil...same stuff they use in jet turbine engines. It resists heat breakdown better than any other and the additive pack is superb.
K&N filters are good, but there's better for the $$$ (Wix or PureOne)...K&N are Champion Labs filters. Take a look at this thread for a comparison:
Here's a primer on oil analysis:
Oil Analysis Basics
Using analysis you can run Red Line in a street car far above the usual change interval...I've seen guys run this oil 15K before changing it. You will get a base TBN when you do the VoA, when your UoA shows a TBN drop to the 2-3 range, it's time to change the oil.
When you get the results (both VoA and UoA), post them here:

BTW - this little gizmo makes taking an oil sample uber easy
