OAT coolants used to have that corrosion problem. BUT they all have been reformulated and Cummins does approve. BTW: That Amsoil c--p does NOT meet Cummins or any other diesel mfr. specs. It is NOT approved.

Basically, the green/blue is old, red/orange is new. I use Peak Final Charge Global Extended Life...it meets Cummins 14603 standards.

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.

OK, have to ask-- why don't you want to run an OAT-based coolant. That is the high end coolant by Caterpillar and Cummins (Fleetguard) as well as others for their diesel engines???
I was wondering the same thing. The new stuff is good for years. I put propylene glycol in the Aqua Hot, not the Cummins.
I have a copper heater core. OAT corrosion inhibitors provide excellent long-term protection for aluminum and cast iron, but may not be the best choice for older cooling systems that have copper/brass radiators and heater cores, especially the lead solder used in them.

Both I and my wallet are tired of changing the propylene glycol coolant in my Cummins ISC350 every two years, as well as adding a DCA when needed.
I saw this online and wondered if anyone on this forum is using it as it has a 7 year/750,000 mile extended service life. I know Amsoil products are of superior quality, but this one is new to me.

For those who may suggest it.......I do not want to run an OAT coolant.
