Wait do the R/Ts require premium? Or do you just get a boost if you do use it?
I believe the info from Dodge read that the R/T with the refreshed engine (370/375 HP) requires 87 octane, but prefers 89. That's blended gas - not high test and not regular.
Only the SRT requires 91 octane. Odd since the compression ratio is actually lower than the R/T on the 2009 engines.
