I did not know that about the 6.4 which is awesome that it can run on the lower octane fuel. Thanks for clearing that part up.
When a post starts with, buying the Hemi WAS a good idea, I am sorry but it could suggest you as the poster had doubt if it was or not, if you have no doubt in what you bought that's great, it is a good feeling! I have no doubt in MY truck, that I did MY math on for MY purpose. Others may tell me that a different brand, transmission, gas, Diesel engine is better, but that's sounds like THEIR truck and not MY truck.
