如果您的车是福特的EXPEDITION,那一点也不奇怪,但是如果是2L以下的车就比我稍差点,我曾经是17升,现在降到10-11升。

我没找到明显的证据表明是那个东西不好废油的,但又几个有关的地方可能有参考价值:1)换了失效的怠速控制电机;2)精确调整了火花塞的间隙;3)更换传动液改善了70-80KM一下的传动效率;4)缓慢启步,不再与别人比谁启步快。

我以前经常行驶不到900米就关机了,我发现在每次点火后油表降的特明显,估计会有1升左右,这可解释为油甭把油抽到了油路里,但这部分油并没有真正燃烧,

奇怪的是再点火时并没有发现上次没用的油返回到油箱了(可能漏或蒸发了),所以油都浪费在这种启动的过程中了,现在我尽量减少这种1000米的短途。
