    Hey guys,
    My brother has been pushing me to swith from Shell V-Power to Arco 91 Octane. He and I are/were both avid users of shell v-power and never really like Arco. Anyways a few months ago he had to fill up with ARCO and appearantly gained about 30 miles to the tank by using it. He's been using it since and the increase in Mileage has been constant. So I decided I would give it a try. Here are my results.

    I usually get about 250-260to the 1/4 tand and fill up with about 16.4 Gallons.
    ARCO
    1st fill: 282 miles filled with 16.185 gallons
    2nd fill: 290 miles filled with 16.253 gallons
    3rd fill: 292 miles filled with 16.211 gallons
    4th fill: 287 miles filled with 16.177 gallons
    5th fill: 285 miles filled with 16.287 gallons

    I couldn't believe it so I decided to go back to shell this last time:
    result: 265 miles filled with 16.235

    Driving habits have all stayed the same. I haven't used the A/C and the city highway ratio has stayed practically the same. Weird?

    Does the Arco have ethanol in it?

    you are getting better gas mileage because your engine is burning more gunk than gas! stay away from Arco if you want to keep your truck for a while.

    If the Arco doesn't use ethanol and the Shell does, that could be the difference in mileage. I know E85 gas hurts fuel economy, so I would assume E10 would too, only to a lesser extent.:notsure:

    I've recently had a significant jump in my mileage. Here in NV and CA, they change the blend in winter vs summer to combat smog. The summer blend had always given my Chevy 1500 1-2 mpg better. This is my first summer since break-in on the Tacoma, but the MPG jump has been substantial. I buy several different brands.

    Stick on hood scoop from Autozone.
    Arco is all I ever use and I always get the best mileage with them. In states with no Arco, I usually use Shell or Sinclair and the mileage is usually about 1-2 MPG less.

    65,XXX, no issues. Oil is good.



    On my/my mom's old 98 Honda Civic: 212,XXX, no issues whatsoever. Ran on Arco it's whole life. It was totalled in an accident.

    Is it possible that shell v-power has so many additives that it actually ends up hurting ur gas mileage? In other words, your getting less "actual gas" per gallon?

    I was thinking that same thing. What's with the Nitrogen additive? What the hell does that do?

    :D I think you're right. I'm surprised one of the gas companies haven't started selling "synthetic" or "hybrid" gas.

    I remember seeing a commercial, I think it was suppousted to clean the intake valves or something like that because they show the difference between their gas's and other gas's intake valves.

    Which is probably complete BS

    on the selling thing a girl i dated for a while her VW bug called for premium gas, we were low on gas one day and in a hurry we drove passed a shell station and to a BP when i asked her why she didnt stop at the shell her response was that her car takes premium upon further probing she informed me that shell only sells v-power gas and her car has an inline motor, incapable of burning v-power fuel. i almost crapped my pants.

    Just how long is "for a while?

    Had my 79 Toyota 4wd pickup for close to 30 years and it ran Arco probably 98% of the time. :cool:

    FYI, the gasoline you buy at a "name brand" station is likely exactly the same as the gasoline you buy at a discount station (e.g., ARCO, Wal-Mart, etc.) with the only exception being the proprietary additives each company adds to their brand of gasoline. Gasoline is refined and distributed at the wholesale level. If you followed a fuel truck you would watch it make stops at every gas station in town, regardless of what is painted on the side.

    Source:
    http://www.eia.doe.gov/neic/experts/contactexperts.htm (see #2)

    In fact, the most important factor in buying gasoline is often how long the gasoline has been sitting in the tanks underground (water content). I would rather fill up from the Super Wal-Mart that gets fresh fuel delivered twice daily than drive outside of town to a small Shell station that *maybe* restocks premium every other week.
