RE: R/T six speed needs 91 Octane?
DO NOT use regular.....I used regular because i didnt read the manual in my 5.7 hemi truck and ended up flushing the motor and replacing some parts because of all the nasty build up in my engine.....at 30k miles.....so please save yourself 400+ dollars and use mid grade or premium.

I did something odd. I read the owners manual to my car yesterday. The owners manual recomends 89 octane for the automatic and 91 for the 6 speed cars. The dealer never mentioned this and nothing is indicated in the fueling area as to what the required fuel (octane) should be. Frankly I have been running regular with no noticeable pinging. What are you six speed owners putting in your tank?

Albeeno, in the St. Louis area, there are several stations that feature 93. I believe it depends a lot on which gas station and brand it is. Mobil always seemed to feature 93 down here. QT tends to only have 91. I cannot remember what Shell has. Phillips 66 has it sometimes. I can't remember what BP has. Gateway F/S has 93 octane. MFA Oil only has 91.
Kevin, I've never heard of that happening before, where were you getting your gas from?

I think it is odd that there is no indication (a decal) in the fueling area about octane requirement. I have owned many high performance cars in my 47 years and I am a little disapointed in the manufacturer but so is the US Congress. I still love the car. I have never owned anything new that gets this type of attention. The Challenger is really rare still in my area.

91 octane isn't readily available here in my area, 87, 89 and 93. Even though my Challenger is an auto, it's had premium from day one. I don't want the ECM remotely thinking it has to retard timing because of octane deficiency. Also, I think it's better in the long run for the engine, I get 16 city and 24 highway, car has 1700 miles on it.
