I just purchased my GXP not too long ago and its about that time to do my oil change. I have been kicking this one around. I have called some shops and seems like Valvoline Instant Oil Change and the local Pontiac dealer have the best prices on full syn. They said 69.99 for the job. I went to Pep Boys and priced out some Mobil 1 with a Mobil 1 filter and for six quarts it comes to $58. Its only an $11 difference and think I am just gonna go with them unless someone can tell me if Mobil 1 is worth the work of doing it myself. I have all the tools I need and a jack. The only issue I am scared of is where I should put the jack on the underside of the car. Basically my question is this.
Should I just go to Valvoline or Pontiac to get the job done or just do it myself for the Mobil 1?
Also does anyone know what brand oil GM dealers use at their shops?
Thanks for your help
