So I found that you can do two rebates per household. You can get $15 dollar rebate on 5 quarts and a matching filter, or $12 on just the oil. Best deal "for me" is the 15k extended milage and the mobile 1 filter off Amaszon for 35.25 - 15 = 20.25, free shipping "prime" no tax. Still need the extra .5-1 quart, I think I used about 6/10ths of a quart on my last change.
