Doesn't matter what weight oil you use to lubricate the wall, just get cheap oil.
Cool thanks for the info

The issue I have with the CP specs is that it gives you the formula for the MINIMUM gap, but nothing about what's optimal. I'm thinking 0.016 to 0.017 is probably a good size, provided that what I've been told about the ring gap being wider not affecting blow by is true. So when I get my new set I think this will be a safe gap to run with.
