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.
If it were me, I would stick with Fleetguard coolant. You say you don't want an OAT coolant but if you don't use OAT chemistry then you are going to have some type of DCA/SCA. There isn't anything else to protect you against cavitation damage.
