15.9 gallons if the size is the same as a SRT & I can't see why it wouldn't be.
I'd stick w/ premium simply because that's what the car calls for. You can certainly run mid-grade but I'd drive the car like a old man then (hey, I AM an old man!). There are a whole bunch of threads about gas (including some by your's truly), I'd take the time to read through some. Many stations mix Ethanol in the lower grade gasolines, many do not do the same with premium.
