How often do you change oil in your car?

Every 10,000. I own a German luxury car.

Check your owners manual. Every car is different

An oil change is pretty cheap vs buying a new engine or car due to break down because you are trying to squeeze a few thousand more miles out of it.

First off, I don't change it, secondly, whenever my mechanic texts me.

When my sensor reads ~10% (~8k miles) I bring it in. Free oil change on my diesel at BH is where it's at!

This.

Generally speaking, regular oil should be changed every 3-5k while synthetics should last 8-10k.

But check your owners manual.

Once a year

that's a bold strategy, cotton

5k full synthetic.

But you should still check the level periodically. Most cars will burn a little over longer intervals. For example I have to top off 1/2 qt about 2/3rds through the 5k.

With that said the reality is the engine will probably long outlast all the other components that break and end up making the car not worth keeping.

I do every 3000. I average about 1500 every two weeks because of work.
