Thanks, I guess I confused compatibility with recomended. What I
must have read, some where at some time in the past, is that you
should not mix the two. Now I understand that if you are full of
Cat extended adding an off the shelf brand would retard it's
lifespan. But there is no compatibility problem of any consequence,
the two will work together, but only at the life span interval of
the inferior antifreeze type.

Thanks again.
