    Gasoline in the U.S. has certain minimum standards.

    As such all gasoline is exactly the same in that

    respect. Some gas companies will add certain

    additives to their gasoline that supposedly will do

    certain other things they claim improves their gas

    over others. However, this is not a fact.

    With the exception of the grade difference in gasoline

    all gasolines do exactly the same as others. What

    can make a difference is in the way your car may

    handle the additives. One brand of gasoline may seem

    to perform better than another, but this is only due to

    the way your car is tuned, the size of your carburetor

    jets, or the fact that your injectors may not handle

    the different additives as well after running another

    brand for a good while. If this latter is the case, just

    use a good injector cleaner in your gas for a while, and

    it should clear that part up for you.

    Other than these things, no gasoline is actually any

    better than another, and to buy cheaper gas is not

    buying a cheaper quality product. Some people say

    that one brand, or station 'waters down' their gas.

    This is not true! State inspectors check the quantity,

    and quality of gas on a regular basis. If someone

    suspects a problem in the gas, or the station, they

    can call the state (info listed on all gas pumps with

    the state inspection sticker) and make a complaint.

    That station will be checked again on the basis of the

    complaint, and without any information given to the

    station on the complainant, or the complaint itself.

    All gas storage tanks do have a problem of condensation

    inside the tanks. As a result there can be a build up of

    water in the tank. However, this water remains in the

    bottom of the tank as gas floats on water. The water is

    never mixed into the gasoline. Stations are required to

    do a water check test regularly. When a lot of water

    has accumulated in their tank they cannot get as much

    gas in the tank to sell. They would then contact a

    company to pump that water out.

    Where most people get water in their gasoline is due

    to the condensation in their own gas tank in the car.

    That is one of the reasons that ethanol is added to the

    gasoline by the petroleum companies. (It also makes

    them more money to use a little alcohol, and less


    In winter months it is suggested that a person keep

    their gas tank no less than half full. This tends to

    prevent the condensation. Filling the tank as soon as

    the gauge shows half a tank can keep the moisture

    at a very minimum level. Should you have a problem

    of gas line freeze during the winter, or wish to prevent

    it, you don't have to buy anything special in the way of

    a gasoline antifreeze. All you need to use is some

    regular Isopropol Alcohol. (Regular rubbing alcohol that

    you can get at any pharmacy, and many other places.)

    This comes in a 16 oz bottle, but you don't need to use

    a whole bottle. I prefer to use half a bottle in a tank of

    gas. This product can also unfreeze a frozen gas line

    for you to drive after only a few minutes work in putting

    it in, shaking the car to mix the alcohol in the gas, then

    making several attempts to start the car after a few

    minutes. (This causes the fuel pump to push the

    alcohol gas to, and through the frozen line to the

    combustion chamber.) At times in the past I have

    had to work with a frozen line from just three or four

    minutes with a partial freeze, to about 45 minutes with

    a solidly frozen line. (incidentally, the Army buys 55 gal.

    drums of this alcohol to pump into quart cans for units

    to use. I still have some of the quart cans of Isopropol

    Alcohol. (gov issue)

    Typically all gas is the same until the proprietary additives are included. I believe Chevron is the best Gas from personal experience. I developed trouble with my motorcycle stalling when I would come to a stand still at intersections. This developed suddenly and could not figure it out on my own. I consulted with a mechanic who quickly determined over the phone through a series of questions that it was the gas I just filled up with (Mobil). He recommended to drain the gas and fill it up with either Chevron or Texaco which at the time were still two different companies. The first tank of gas corrected the problem. The mechanic explained that Chevron did not add "fillers" and that the smaller engines running higher compression needed higher performing Gas (note I used the same octane rated gas for both Mobil and Chevron). That was the first (and last) time I used Mobil in my motorcycle.

    By the way when people say gas is "watered down" they don't actually mean diluted with water! Ethanol is a perfect example of "watering down" pure gas which will reduce your gas mileage. I stick with the term "fillers" because it won't confuse people about actually adding water (which does not mix with gas). Several brand name gasoline companies add less expensive fillers as state laws allow. These low cost fillers increase profit margin while degrading the gasoline to some degree (not much for your typical passenger vehicle).

    Did you know that gas is burned by the pound but sold by volume. The pound of gas per volume varies greatly with temperature changes. In the 1980s and 90s companies would actually heat the gas prior to putting it into the tanks underground (great insulator) and sell you less pounds for the same volume. This has since been corrected with pumps that correct for temperature when dispensing gasoline. Even so, to this day if I feel the handle is warm when gas is flowing I stop going to that gas station.

    Hope this helps,

    I like near Google where gasoline prices at several stations located on the same intersection near them are higher than they are at similar stations a bit farther away. The Arco station in that area is actually 35-40 cents cheaper that they are at the Chevron just across the street from it. The Shell is 15 cents cheaper. Of course Chevron is running a "20-cents-back-per-gallon" program in cahoots with Safeway grocery stores, where you get the 20 cent/gal credits for shopping at said store. Instead of a bargain, it sounds like Chevron is charging even more to cover the cost of this so-called "discount", so you really get back nada. ARCO for me. Their gas works fine.
