不算離譜，你自己也可以估算一下。

1，PENNZOIL PLATINUM SYNTHETIC OIL CHANGE LABOR :26.75 --- 省不了的。自己幹:-26.75

2,QT 0W20 PZL SYNEBOX QTY: 5 ECAH: 7.99 =39.95 --- ON SALE 時自己買，也得20出頭。自己買:-15

3, PROLINE OIL FILTER ：7.89 --- 自己買，也得5塊吧。省：-2.89

TAX：2.88 --- 就算能省。-2.88

TOTAL ：77.47 --- 能省：2.88+2.89+15+26.75=47.52 approximately.
That's why I do it myself and I believe many guys here also do it themselves.
