It's dyno...and it's very, very old. We sold SE-class oil when I worked in a parts store back in the late '70s!

Just go down to wal-mart and get yourself a jug of 10-30 wal-mart oil and you are good for 6 months

Hold your horse here partner. SE, SF, etc were all acceptable grades of oil when they were first manufactured or refined. As the chemical process and refining processes improved the auto manufacturers demanded a better and better oil. Thus, oils used to be SC and SD, etc. KMart oil and Penzoil all share the same grade. That is, they meet the same MINIMUM requirement to be an SF oil.

my comments are from tearing down engines in the 70's that were sooooooo crudded up from cheap oils the the pushrods wouldn't move.
Besides why would anyone want to save less than $2 on an oil change buying cheap oil?
