How often do you change your oil?

I just follow the car’s reminder system. Toyota engineers seem to know what they’re doing!

2015 Sienna, 155k miles. I change the oil every 12-15k miles, no issues so far. I use Pennzoil or Castrol full synthetic.

Love hearing this. Thanks for sharing.

If you want to see a different perspective, check out this explanation from Car Care Nut on YouTube: https://youtube.com/shorts/BI5zQIH1jIY?si=5AvEIqJHcc56eFPb

I follow the manual and do it every 10k miles.

I stick to 5k or every 6 months.
