rotella ELC... yes or no?

[cjohnson]

I need to change my coolant but can't find any fleetguard A/F in my area. I picked up some Rotella ELC, but I'm nervous about using it. I know it is one of the extended change blends, similar to the Havoline. It's even red like the Havoline. So is this stuff o. k. or what? So much debate, but doesn't seem to be a good answer. Help.....

Any high quality anti freeze will do just fine. There are really no restrictions on the Cummins. Pete

Well now that I've stuck my foot in my mouth, let me say that the service manual claims that ethylene-glycol is better than propylene-glycol and that you should not mix them, Vol. 1 pg 7-40. Pete
