manipulate this. They know the diesel cars are most commercial, have to run.
So they keep the diesel price high. |

发帖数: 5998 | 3 Just couple of years ago, both were similar priced and the diesel was
actually cheaper than most of the 92+ premium gas. Only when the price of
gas spiked up recently, we saw diesel prices goes up substantially more.
Since diesel is offering more MPG, guess the oil company thinks consumers
would still justify the price premium. Basically, like Saleen said, they
will charge what ever price they can get away with. |

跟石油提炼工艺有关，美国的汽油消耗大，用的催化提炼方式产汽油多，柴油少。
欧洲柴油消耗比较多，用的比较高级的加氢裂化，产柴油比例多点。 |
