Yup. I've done plenty of cars where I got 5 qts of synthetic oil for $20-25 and filter for $5-10. Many shops charge $70+ for that.
NOT at AutoZone or O'Rieliys where they charge $45 for the same 5 qt jug that can be had across the street at Walmart for $20. No that 15 mins does not include sourcing the oil/filter and disposal, but I usually do that days before and after.
Most cars take 4-5 qts. Here's Quaker State synthetic for $21.50
Here's a filter for a 2014 Camry for $7.50
You can get drain plug crush washers in bulk on eBay or Amazon, but let's say it's 25 cents each.
Comes out to a few cents under $30. This is on the lower end but certainly doable for significantly cheaper for most cars than at most oil change places.
