    Go ahead and post those dyno results of 4 octane points making a 40 HP difference. I'd love to see them.
    Not required but it's RECOMMENDED...I'll spend the extra $20 a month for premium

    In Wisconsin it's a difference of 87 vs 93 at most gas station, that's 6 points. Through tuning AND higher octane 40 hp may be achievable in extreme cases.

    Re: Does new 6.2 require 92 octane?

    I agree with the poster above who would love to see a dyno chart that proves a 40 hp difference made by gasoline.
    Horsepower isn't made by a higher octane gasoline. 87 octane in an engine that runs a 10.5 compression ratio is more than enough octane under normal driving, and unless the engine is under duress by towing, or severe demand like running 100 mph into a 40 mile an hour headwind.
    Again, if the engine suffers from power a drop off due to lower octane, it's purely a safety feature employed by GM. Remove the safety feature, and there will be absolutely no horsepower difference in power and performance.
    But if you plan to tow a trailer at high speed on lower octane fuel in high temperatures expect some deadly pre-ignition. Use regular for any regular driving condition, and premium if you plan on getting after it.
    I will probably burn regular 99% of the time, and premium if we tow with it.

    It'll run EXACTLY the same until it reaches extreme power demands (full throttle acceleration, towing, racing...).

    "Premium" isn't "better". It's different.

    The op wasn't concerned with which is better, he was asking if premium is required. The answer is no. It'll run just fine on 87, nothing will get damaged, it'll still have WAY more than enough power... It's fine.

    I fully agree. 99% of the time, it's simply an indulgence with zero payoff. I have other, more entertaining habits to flush money down the toilet. Premium fuel isn't a better diet that expensive vehicle deserves. It's not like high dollar dog food for a champion award winner.

    Exactly Moist, it's simply different, and premium simply remains more stable under higher compression engines. I guess I'm not much of a stock vehicle enthusiast to think a 10.5 compression ratio gets my respect. If it was supercharged where the compression ratio changes, then absolutely I would always buy premium. I run premium in my 12:1 Harley, and in our turbocharged 1100 Arctic Cats.
    My lawn mower and road vehicles get regular without any worry of damage or lost performance.

    JMO guys, and that's why there are choices at the pump.

    That is not exactly true. While I can not prove a HP difference, I can certainly prove a MPG difference as I log all my mileage and expenses.

    This is a point I didn't consider. If the ECM does dial back timing to in some instances to compensate lower octane, fuel mileage might be affected. Just how much?

    Reels, can you post your MPG differences.

    Sitting on the patio reading what I started... Comical day to say the least. Oh, And yes I meant 91, not 92.

    Re: Does new 6.2 require 92 octane?

    This is on a 2013 6.2.

    Most of my miles are Iowa highway miles, average 70MPH. 87 Octane with ethanol 16.5-17MPG. No Ethanol 87 18-19. 91 No Ethanol 20-21. Wind direction and flatness have big influences. MPG will go down on hilly stretches. You would think it would even out, but it takes more fuel going up a hill than you save going down it.

    2015 may be different, but wording is almost identical in the manuals.

    No, I haven't run 91 Ethanol, at least not knowingly.

    Given the ethanol difference in the 87 category, the 91 ethanol should resemble the same numbers as the 87 non ethanol.
    Unfortunately, it's tough to find anything non ethanol in these parts..
