Well, the PB VPC/Puro you have to rebate but I prefer the filter. Easy 5k though.
Splitting hairs really, either will do 5k just fine. I'd likely take the PB deal if there was one close by. If not, go AZ.
Id say Valvoline as well. I've used the slightly different Canadian version mobil super 1000, and valvoline all climate. They both did well, BUT, I like the valvolines cold pour properties MUCH better than our Mobil at least. Both would be good though. At those prices, Id still go with Valvoline though.
