Changing A/F in a 3208

[Eric Johnson]

Bruce,
I buy it a case at a time from Cat dealers for a "mere" $10-$12/gallon. Cat
stuff is not
cheap but afterall it is prediluted with 50% water and I don't think they use
Perrier for
diluent. It is Cat ELC. I've had no gelling or other problems. Just dumb
luck I guess as I
never got past a B.S. in ChE.
