The 24 shops on this page change oil in Boulder, CO. Some are drive-up quick-lube bays, some are repair shops fitting you in between bigger jobs. What each one says about oil brands, grades and what the price includes comes from its own website.
Usually not at a dedicated quick-lube bay; the whole business model is drive-ups. A repair shop is different, because they are slotting you between bigger jobs, so a phone call first can save you sitting in the waiting room.
Around half an hour of actual work once your turn comes, plus whatever queue is ahead of you. A shop that hands the keys back in a few minutes did not let the oil finish draining, and a shop that keeps the car all afternoon has found something else to tell you about.
Ask which oil went in and whether it meets your manufacturer's approval, then look at the dipstick while the engine is still cool. Make sure the reminder is reset. Keep the receipt with the grade written on it, because that paper is what a warranty claim rests on.
