Q: Why does an Hummer H3 oil change cost more? 2003 Hummer H3

asked by on

Just want to know

My car has 149000 miles.
My car has an automatic transmission.

Hello - the H3 has a 6-quart oil change capacity, which is more than most engines these days (4 or 5 qts), and synthetic oil is recommended. These are the only 2 logical reasons for increased oil change cost. Hope this is helpful!
