Waiting on the rebate now based off of your advice, they sent $20 already, hoping to cash in on the last $10.Great choice, and good timing. You can max out that Valvoline rebate with that purchase. I did the same. Got enough for 4 OCIs for our two vehicles before the end of the rebate. (Although they likely will have another one.) Will re-evaluate things after the 4 OCIs, but after I use up the rest of the on sale stash, probably will go back to VRP.
