I am ready to go for my first oil change and was thinking of going to the dealer. I have the option to choose between Glendale Infiniti-$32 with Mobil 5W-30 or Santa Monica Infiniti-$42 with Penzoil 10W-30.
Where would you recommend I go?
Thanks.

May not help, but Wal-Mart has 5-quart bottles of Mobil 1 for $20. You can get a Mobil 1 filter for around $10 at a car part store. IMO, good synthetic for less than regular oil and only a little bit of your time (except for all those damn screws on the aero panel) is well worth it. If you can do it yourself, you're better off. Otherwise, I don't know of that much difference in regular Pennzoil and Mobil (at the same grade).
