I have two stupid questions on this topic. 1) Do these fuels harm the carb? 2) If no to #1, then the problem would be with detonation, no? So wouldn't that just go away with an air cooled intake, like with water injection, or by adjusting the timing? Are the timing portions of the stock ignitions bad at being adjusted? Get an aftermarket msd ignition or something which can: A) be adjusted from inside the car, B) can have optional rev limitors and adjustors, C) the ability to adust timing during differnt rpm ranges, D) better adjustable retards. 'course msd stuff is always alot more $$, but its worth it, especially if it ends knock! 3) This is a point, not a question, but my 3.3 (same as the Imperial) doesn't get confused or screwed up when I use differnt fuels. I guess Mopar pcms think faster then Ford and GM PCMs which can't keep up with an engine's fuel system (makes you wonder if Mopar PCMs run Mac OS and GM's/Fords WindozeXP or something:) [no, I really do know that Mopar pcms use assembly... no true OS....]. --- "Wm.
