Very Interesting,

Especially your comment on older vehicles. My vehicle has the small ford V8 with
over 100 thousand miles on it. It still runs great, but it has real noise
problems.

I will add Acell to the list. Since I am unfamiliar with any of the names, your
recommendation would be appreciated.
