    Default Best gas

    I'm new to this whole "high performance" thing, driving beaters most of my life. So I'm wondering who has the best most dick-curlingly potent gasoline for my baby? It's for the CBR600RR but I figured it would get more feedback here than bike talk. I used Esso in the cars, mostly due to Speedpass, but it makes the bike run like shit. My friend claims Shell has the best and it seems to do the job, any other opinions??

    After doing some work and to my STI I data logged gas A tank of Esso 91, Petro 91, Shell 91, and Husky 94.

    Cant remember the exact numbers but the gasses in order from least knock and timing retardation to most (aka best to worst)

    Shell, Esso, Husky, Petro

    I think Husky's 94 was lower solely because of its ethonol content. I was able to adjust my tune for this but my gas milage became shittier than it already as and switched back to shell 91

    If you look at the composition of ethanol it contains oxygen, this means that you are getting unmetered oxygen into the combustion process, this results in a temporary lean condition which is corrected by using 02 input to richen your fuel map. Ethanol contains less energy per unit volume so not only will you use more fuel, you'll get less power per unit volume, that is why gas mileage is so shitty with ethanol.

    This also means that if you drive an old vehicle that can't adjust fuel maps to compensate for the lean condition you'll be leaning it out all the time and it probably won't run well

    Also as explained to me by a friend if you switch back and forth your computer will have to be adjusting fuel trims every tank so this will hit you fuel economy as well.

    Disagree, I have made more power with almost all 91 brands than the husky 94. Also recorded less knock with the 91. It may be that turnover in the stations tanks is slower with the 94 , so it absorbs more water lowering the octane.

    Fuck I think I might be the only person who can't tell the difference between different brands of gas. Between all the cars I've owned (turbo, NA), I've seriously noticed no difference LOL. The only place I've been avoiding is Centex (per my mechanic) and Superstore but if I am out of options, I'll still go to Superstore. I've been mostly going to Costco simply due to price, and my car doesn't seem to know the diff (I seem to alternate between Costco and Shell). Not sure if Costco premium has ethanol but there's a sticker ONLY on the regular side that says may contain up to 10% ethanol, nothing on the premium side.
    You have a couple of photos that are great... you must be very good at photoshop!

    Any idea where COOP gets their gas?

    I've always filled up at Shell, but there's a coop gas bar right on my street now and it's so much closer to fill up and wash the car there.

    Many moons ago, they used shell gas, without the additives. That wad 7-8 years ago though, so it may have changed.

    They're certainly big, but I don't know if they are the BEST I've tasted.

    Just filled and noticed a sign pointing to http://www.shell.ca/nitrogen/

    Shell V-Power is our best, most advanced gasoline that contains the highest concentration of the NEW Nitrogen Enriched Cleaning System, a unique and patented formula exclusive to Shell. With five times the amount of cleaning agents required by government standards, Shell V-Power gasoline cleans up engine gunk faster than Shell Nitrogen Enriched Bronze gasoline and is designed for all vehicles – even today's most complex and advanced vehicles.
    So no ethanol, but nitrogen and the TOP TIER detergents, which you can read about on their site.

    I'm with you. I run superstore gas all the time in all our vehicles, never noticed any difference.
