非常感謝各位的熱心回答。我也上網查了一下。SUBARU車：1st oil change：

1st oil change 
all models- 6 months or 6,000 miles, whichever comes first.
Its ok to change early, especially with hard driving, cold/hot weather, or manual transmissions that are revved up or downshifted. Its up to the individual owner

我的車剛開了個3月和3000km（=2000ml）。如果我下個星期的長途開6000km。總共有9000km裏程，正好快到6000 miles (=9600km), 回來後也正好換油。再次謝謝各位熱心的朋友。

• 不換機油,也換個濾芯,通常新車機油內的抗磨劑較高, -khyang86- ♂ (301 bytes) () 07/25/2016 postreply 18:31:53
