Valvoline puts a promotion out every now and then for their Maxlife oil, and I'm sure some of you guys can use this. I did this promotion when they ran it a few months ago, and received the rebate check w/o any issues. Furthermore, if you have a Walmart around you, I found that this was the cheapest place to buy oil, since most of us will be needing the extra qt.
Here's the link:
