Sharing this and saving it for later—
The terms: $10 rebate on 5 quarts or $2 rebate on 1 quart of Pennzoil Ultra Platinum or Platinum Synthetic oil at participating retailers (the list is pretty much every common box store and auto parts chain AND Amazon). Usable twice per person or address until December 2018. The receipt can be submitted electronically, no mail-in required.
I just filed it to get $10 off this oil change and will do it for the next one too. 🙂
