Chris,

I use a quart of Marvel at oil change time.
I throw a 1/2 pint in the gas when I fill up.

BTW, I was talking to Bob Donalds about the burnt valve in my recently
acquired 74 Westy, and I told him I was going to use Marvel in the gas
to help lubricate the stems and guides, to help prevent this from
happenening again.----His reply was, " Good Stuff."

Later,
