On the other Forum I been watching a debate about motor oils for Flat Tappet Cams.
I am about to try the Brad Penn 10W - 30 oil. I have been using Castrol but it seems the Wal-Mart self oils are no longer suitable for the older cars. Specifications changed in 2005.
Have you heard of this problem with ZDDP levels that changed in 2005?
What oil are you using in your C-1's, C2's and C3's with flat tappet cams?
