After seeing the PQIA results for the QS-HM 5w30, I went ahead and switched to it. I've been contemplating on using this oil before but wasn't sure. Additive package is great, and has a strong TBN. With the info in the link below, how much would you run this oil for? 5-6k miles? It's a syn-blend but I don't think it's 50-50.
