This is what I do...2025 Hybrid. How do you decide when to change the oil?
Do you trust the "onboard oil quality monitor" to decide when to change the oil?
Do you go by the mileage?
Do you listen to the dealer?
On my previous vehicle, I used to change my full synthetic oil every 10 to 12 000 miles. My dealer put a sticker after the last oil change, to change the oil again in 4000 miles. Why to pay more for full synthetic oil if I still have to change it that often?
I looked for other discussions on this forum about this subject but, surprisingly, I found none.
Thank you.
Does the oil have a heavy odor of gasoline?
Is the color on the dipstick dark?
In a cold climate, is there a problem with condensation in the crankcase due to too few or not long enough trips?
A yes to 2 out of 3 will warrant a change IMO. Myself I don't exceed 5,000 miles per change and at a minimum if mileage isn't met change it twice annually. Once going into winter and once going into spring.
Do what you will. I don't think 3 or 4,000 miles is unreasonable, synthetic or not. Especially given all the extra starts a hybrid ICE goes through.
