It's interesting; so many things that we use today just don't require much maintenance. When we purchase something like a television or a toaster oven, we don't ever expect to have to take them to a repair shop. They may require a bit of cleaning now and then, but that's just about all the maintenance we expect to do. If things stop working, we just replace them. It hasn't always been that way, but with advances in technology and automation, repair costs can easily surpass purchase costs on many common household items.
Maybe there will come a day when even cars don't need maintenance, but we aren't there yet -- even though automotive technology has changed a lot in the past several years. There are a lot more electric vehicles on the road that don't require oil changes. But, if you are like most people and are driving a traditional gasoline or hybrid vehicle you need an oil change to protect your engine from damage.
