RE: R/T six speed needs 91 Octane?
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.
