Our Ford dealer does a good job, something like 26$, wash car, check fluids/filters, tires, etc. My Dad has one done there. We do the rest because of time/convenience, usually when they are up for something else or its really time but I have oil dump, hoist etc. My secretary pays 30k for a truck and worries about saving 2$ doing her own, takes her half a day. Especially in winter, waste of time. Goes into a panic when the odometer rolls over 3k, breaks out in a sweat.
The one qt flush is a new one on me too, pretty much mental ************ there and has nothing to do with engine life. Most people that panic about oil do so because thats about all they know about cars, leaves them with a warm fuzzy feeling I guesss.
So much more, air filter, heading off brake and wheel problems, looking for exhaust hanger issues, clogged vents in rear ends, shock mounts, mud in wheels, a big one is tire pressure and grease to steering parts.
