Well I just saved $40 on my oil change by buying my own oil. They charged 10.95 a quart last time. At my boyfriends suggestion I called the dealer first and they said there was no problem if I brought in my own oil. I bought Mobil 1 0w-40 for under $5 a quart. I still got the filter thru them. But they didn't charge any more than the standard $10 for labor on an oil change. Thought I would share!!
