My Toyota dealer is now stocking Toyota brand 0-20 Full Synthetic oil. I have no idea who makes it for them but the cost per quart is $4.45. The price is almost a $1 cheaper/quart than Mobil 1 0-20 or 5-20 at Walmart. I know that some of you will disagree with me, but it seems to me that using the Toyota brand is a no brainer. If you do your own oil change, you should spend no more than $26 for the oil and a Toyota filter. That's cheap for a full synthetic change.
