The great thing about being on a growing listserv is that you get to tell
all your war stories over and over and over again. What great "old man"
training.

:-)

My brand spanking new 92 Toyota truck was supposed to run on regular, but
even under perfect tune, it would knock like crazy. I hear they were all
that way.

It ran great on premium, so that's what I used and didn't think much more
about it.

My '87 Syncro has never shown any signs of detonation, so I use regular.

I have been told that using premium is a good idea for air cooleds, as
their more extreme temperature variations can induce destructive periods of
intermittent, relatively undetectable detonation.
