Here in Vegas went to Auto Zone, O'Reillys, and Car Quest, no straight 30wt., anymore. Did not get to Napa. Not even 15-40, only 15-30 too thin? Ok to add ZDDP to synthetic oils? I can save the MMO for the gasoline. The engine was rebuilt about twenty years ago by me. At that time put in hardened valve seats, etc. Has 13,000 miles on it since then.
