FWIW, Brad Penn
oil is the Kendall
oil that we all knew as kids. It's green, and always has been green. The Kendall
oil they sell now is
not the Kendall oil of yesteryear. The GM EOS that they sell now is
not the GM EOS that they sold many years ago. The "classic old school" oiling method that everyone I ever knew, and who is still alive, used back in the day for a SFT, and before ZDDP was a household word, was to use Kendall oil with a bottle of EOS. But, if you just trot to the auto parts store this afternoon and brought home Kendall Oil and a bottle of GM EOS, it would be completely different from what it once was.
