After searching through some threads on oils etc I saw a few people state that valvoline vr1 is getting harder to come by. Here is a link on amazon for 40 w vr1 for $66 for a case of 12 quarts. $5.50 a quart. Just thought I would give a heads up for anyone that is looking to do their winterizing/fluid changes here soon.
