I use 93, runs better with it, I have the tune to use higher octane too. Before the tune it still ran better with higher octane.

I agree 100%. My SRT will knock down 24 MPG at 80mph. I have friends with the active displacement 5.7s that get 28MPG. What he will save buying 87 octane he will lose due to lower efficiency/higher consumption.

I get up to 26 at that speed with mine. Granted I did a few things with mine, got the tickets to prove it, oh well,,, To the OP, run the higher octane, it's worth it. Just in driveabilty it's worth it. Don't cripple your R/T. It'll still be stout with 87 but so much better with 91/93. Mine's a stick. I get in so much trouble in NTx and the Panhandle with this. Glad they didn't nail me at 142.

Took my brother for a ride in the SRT... realized at 160 MPH that I'd be going straight to jail if I got caught. It was still pulling strong. Im a believer that the SRTs will run in the mid 170mph range.

If they sense knock the could pull power down about 10%. On an R/T that's about 37 ponies. Try the higher octane and se if its not quicker.
over on one of the charger forums, someone did back-to-back dyno pulls on a chassis dyno with 87, 89, and 93 octane in their challenger. with stock tuning, 89 made the most RWHP, around 328. 87 made about 326 and 93 made the least at about 323.
I've run both 87 and 89 in my 2011 charger R/T and haven't seen any difference in power or mileage....

Anyone using 87 octane fuel for the their 2013 Challenger R/T with manual transmission? Any pinging? Thanks.
You'll never hear pinging, the computer takes care of that, destruction will happen though.

One thing I have found with mine, where I buy gas seems to affect mileage a lot more than grade. On Speedway or Thornton it will consistently knock down 18 around town. Put BP in it the other night and it dropped to 15. Won't do that again.

When the sensor feels knock, it pulls timing out immediately and also backs off base timing. After the "knock event" base timing slowly creeps back up. It may take a full tank worth of driving to adjust base timing up when changing to fuel with higher octane. A test like this would need extended drive time on each fuel between pulls to get accurate results.
