The "Bob's" are in total agreement other than to mention that the
quarts sized StaLube from Napa ends up being quite a bit more
expensive than the CarQuest EP90, which comes in gallons. I recycle a lot
of it so cost matters.
OTOH, I refill a old Stalube quart bottle from my gallon of CarQuest EP90
to use with my hand pump. It's getting old and I should upgrade before the
bottom falls out.
