Tom you are one of those stubborn 87 does all guy and you havre no understanding of octane requirements in modern engines at all and it shows big time. It is because of people like you that gasser get a bad rap sometimes. 87 does not provide the octane needed plan and simple and the timing has to be retards to tolerate it. If you would have pried open your wallet and used better fuel you ould have had a different opinion of it. One of the reasons that Dodge killed it was because people such as your self were addicted to feeding it 87 towing and the engine would tend to ping and this ping (even if not heard because ECM was keeping it a low level) would cause valves to vibrate in seat and over time cause them to start to burn and fail. Rather than up octane requirements in book officailly they tried a bit in 96 bit it proved to not really help much. 87 octane was not design for such usage but wnnabe experts such your self "know" better. I actually studied IC engine desgn and theory in college many years ago and wrote a few papers on it while pesuing a engineering degree so I am not just making this up as I good like most others do. ou simply cannot burn 87 octane in a big engine on a warm day under a heavy load without compromising spark timing a lot and in doing so you kill power and MPG a lot but you would know that too if you really had a clue about what you were talking about.
