Buster I've heard M1 is making their 0W-20 street oil again but I don't see it on their website just their 5W-20?
M1's 0W-20 racing oil vis @ 100C is 7.85 although it's pretty low @ 40C, 41.3 cSt.
A problem I have with NEO is that they don't seem to provide a Product Data Sheet plus it's not available in Canada.
Silkolene is also not available here.
