Pepsiboy. The Cummins engines that were factory filled have liner protection built into the coolant. Even so, the additives have to replenished after time. Cummins sells such. See here : Fleetcool
I just looked at a bottle of automotive extended life coolant. No where does it say diesel liner protection.
I do not believe all "RED antifreeze " will properly protect wet liner diesel engines. I think you're making an unsupported assumption that SCA's are no longer required. Can you provide a link that supports your point?
A dollar or two saved today may mean many $$$ with a perforated liner later.
I use the Fleet coolant from ORilley's...
It is precharged with SCA's and is pink/red in color...
Back when I added SCA's to my antifreeze the fluid was red/pink in color...
I will continue to use the Fleet brand with SCA's in the coolant...
Very convenient for me...
I was not aware of other pink coolants used in cars without SCA's...
