[Healeys] Oil additives -- great informaton. Thanks.

[Bob Spidell]

Walmart had no problem shipping me a crap-ton of Valvoline VR-1 20W-50; 
still don't understand why the outfit in the Midwest I bought from 
before refused to ship to me.  The Valvoline saga has some strange 
twists, a few years ago my favorite parts house 'had to pull it off the 
shelves;' I never got an explanation there, either. I haven't seen it on 
any parts house shelves since, but as long as Wallymart will ship for 
free @ less than $4/qt I'll be happy.
