I’ve been using Valvoline, but I bring my own oil and filter, and they actually do use a torque wrench on everything I can tell. It’s $60 (with coupon) for my 6.7 that I also have them rotate my tires, I’m in and out in 30 min, and I don’t have to dispose of the oil. Just turn down the the other services, especially the air filter (that I typically replace while I’m waiting in line), and they’re not too bad. I just wish they’d do my fuel filters, but LiAbIlItY.
