I took a company truck to a local quick oil change place in town. They drained the oil and put on a new filter. The guy that did it pulled it out and come into the waiting room and asked if the oil pressure gauge worked, (Truck was only a year old). When I responded yes he backed it back into the service bay and put oil in it. Must have got distracted.
I took a personal truck I just purchased (used) to Walmart to have the oil changed since it was January and cold. I paid extra for 7 quarts of synthetic oil. When I got home and checked it they had only put in 5 quarts.
I usually just change my own oil, doesn't take that long. In fact just changed it in my old green Ford F-250 last Sunday at 200k miles. My greese gun was out of greese so I had to run to the auto parts store to pick up a couple of cartridges. I change the oil and filter every 5k miles in all my trucks and SUV's, very easy to keep track of.
