I wouldn't believe it either unless I heard it directly from my earnest friend who learned at that moment:

1) cars have oil

2) said oil should be changed regularly

Unless they were driving very very low miles per year, they are simply incorrect. A car isn't making it over 100k miles without an oil change IMO, even a Toyota.

Similar to how this person went most of a lifetime without noticing and wondering what oil change businesses, advertisements, coupons, etc were for... They also didn't notice someone in their household or a service provider of some kind (brakes, tires, idk) changing their oil.
