Even for DI engines I think it is possible. My wife has a 2011 Hyundai Sonata whose engine got to 215k miles before it blew up (due to a factory defect in how the engine was built.) If we assume an average driver does about 12k per year that is almost 18 years of mileage. Like anything else it is down to how it is maintained and driven. We will see how the new (rebuilt...) engine does. But there isn't any rust on the rest of the car and the trans is still shifting fine. So onwards we go.In most rust free areas of the country a daily driver can last 20 to 25 years. Pretend I never said this if you own a CVT, small engine turbo, or a direct injection engine.
Oil changes are cheap in my opinion. We have enough oil specials and clearances highlighted here that the 10k OCI isn't a worthwhile habit to pursue or discuss.
What is? Quality filters, parts that only need to be replaced once, taking care of small issues before they ever become big ones. Extending the life of batteries. Preventative maintenance... from hoses and belts to detailing and replacing fluids that aren't mentioned in the owners manual..
Figuring out interesting ways to make a car endure the ages is what BITOG is all about.
OCIs? It's too vehicle specific and again, replacing oil is cheap for most of us.
