发帖数: 20444 | 1 2004年宝马等汽车制造商提出“顶级（Top Tier）”汽油标准， 以助于使汽车发动机更为清洁并减少与沉淀物有关的问题。近日美国汽车协会(AAA)表示，顶级汽油比普通汽油值得更高的价格。AAA委托独立实验室随机从三个加油站选择了六种不同的汽油。他们进行测试后发现，汽车同样驾驶4000英里（约6437公里）后，不符合顶级汽油标准的汽油在引擎进气阀中的沉淀平均是顶级汽油的19倍。
这些有害沉积物可导致汽车怠速不稳，增加废气排放，影响汽车效能降低了（可能是消费者最关心的）燃油经济性。
此外，AAA在为期一年的调查中发现，顶级汽油平均每加仑比普通汽油贵了三美分，而大多数消费者只根据价格选购汽油。
美国车主通常在BP、雪佛龙、埃克森美孚和壳牌等公司旗下的加油站找到顶级汽油。 |

Essentially all petroleum marketers buy from whatever refineries are in
their area. Gasoline (and diesel and heating oil) are essentially regional
products because there is not a nationwide network to move refined product.
It is amusing to work at an oil terminal and see 6 or 7 differently branded
(Mobil, BP, Chevron, independents, etc) pull up and load up with exactly the
same gasoline. Amusing because they advertise so much to try to distinguish
themselves - "a tiger in the tank", "the detergent gasoline". All gasolines
have detergent in them. No gasoline is made from tigers (duh).
There IS separate metering equipment to squirt in a bit of each companies'
own additives - "techroline", blah, blah; but what is distributed is already
87, 89 or 91 octane gasoline that meets API standards.
The first answer is clearly wrong in that my nearest Safeway gas outlet only
recieves product from a Williams refinery (by rail) and mostly from a
Tesoro refinery (by pipeline and then tanker truck). Those are the only
refineries in the state and no refined fuel is shipped in except for
aviation gasoline.
Ask at your local Safeway - they may at least be able to tell you which
trucking firm delivers it. Or ask an gas station owner operator down the
block - they keep track of who buys from who and for how much. |

brand. However, each brand would add its respective fuel additives. Top
tier brand probably would add more and higher quality additives. |
