That and the ShellZone are pretty much the same stuff. Just make sure you test your coolant often or do regular interval draining to ensure it's not becoming slightly acidic. Fleetguard sells a test kit and an additive to bring the coolant back to spec. Its Diesel Coolant Additive (DCA) is worth the money and available at all Cummins Dealers.
