in las vegas, so the best we get here is 91 :(
we do have a couple rebel stations in town with 100 octane so i could always mix to get up to 93. but for now i am stock and running on 91

First few fill ups were at 87, since I wasn't doing anything too hard with the motor during break in. Put in 93 with the last fill up, if I don't feel any difference, or see a huge mpg difference, I'll likely go with 87 most of the time, as it's $0.80/gal cheaper.

I've only had Bender for a week, and I filled up with 91. I haven't seen 93 octane yet near Long Beach, CA. I may fill up with 87 octane next tank to see if there's a difference in mileage.

Reporting in from Milton Ontario..

For research purposes I tried 3 different types of fuel.

87 Octane from Petro Canada - This fuel is garbage for the ST. you can literally watch your fuel gauge drop as you drive and the idle is weird

Ultra 94 from Petro Canada- Not a bad fuel at all. Fuel Economy is not bad but not that good either. I got about 6 days out of this tank and it was about 80KM per day while using this one.

V-Power Nitro plus from Shell- This was the best gas I have used so far. I got 11 days out of my tank and was commuting daily. Idle was smooth and quiet and the engine performance felt better overall no matter what speed I was going.

Want to add Shell Vpower Nitro is 0% ethanol 91 octane. Everything else has up to 15% ethanol. Last tidbit the nitro until mid september 2015 in Canada has 20x airmiles.

Yes, Apologies for not adding that Shell V Power Nitro is only 91 Octane. and Yes the Airmiles deal rocks if you are a frequent travel person.

If you're in the U.S., I'm sure Nitro+ comes in 93. It does everywhere around me in Illinois.
