Anyone Using Amsoil Propylene Glycol Coolant In Their Diesel

I probably will go to Cummins locally and see about changing over to
their OAT coolant. Three years ago they talked me out of it. I'll see
what they have to say now, with three more years of experience and
re-formulations. When I see that big poster on their wall offering
an in chassis re-sleeve with a dollar amount (knowing it's more for
a DP than a semi) I either want to get back to my old gas model or
do some serious research on coolants.
