I use RMI-25 in my 95 PSD very successfully (with coolant analysis once to make sure it was working). I am very impressed with it and have used it in all our liquid cooled engines. Now my wife is buying an 07 LBZ Duramax. with all the stories I've heard about Dexcool, can i add a little RMI-25 in this? I am mostly going for the cleaning and lube properties since I believe the duramax doesn't require an additive for cavitation. How is Dexcool now?
