I was in Walmart two days ago looking at oil and they were fully stocked on everything including Mobil. Williamsfield/Market in Gilbert. :) I'm going tonight to contemplate over oil, and I'll let you know.

I can't decide if I should stick with Castrol GTX conventional (what's been in the car since day 1) or switch to Motocraft semi (used on my old 6), or Mobil 1 XD This will be the first oil change on my new '03 62k GT. Not to start a new convo!
