I believe in my case the free oil change would be 5W-20, but I'm not certain of that. I want 0W-20, though, and I don't mind paying more for it. $7.00 per quart is less than what my husband was paying the VW dealer for full synthetic oil changes on his old 99 TDI Jetta, but everything seemed overpriced with VW (which is why my husband is now driving a 2007 Yaris

).
I'd rather pay $7.00 per quart to my Toyota dealer than $4.00 per quart from Wal-Mart. Fortunately, after much Googling and calling around I found a place that has Mobile 1 0W-20 for a little over $5 per quart. I can buy it by the quart or the case from them. I'll be picking up a case

.
Oh, and while we were searching my husband found a place online that has it for $3-something per quart, but who knows if they are trustworthy
