My wife's 2020 Mitsubishi SUV is coming up on 2 years since the last oil change. By the odometer, she has driven a little over 7000 miles. Car gets driven regularly, but short trips. Some 20-30 mins in length every couple weeks so we know the engine gets up to temperature. Oil is full synthetic.
Am I pushing the limits here (or over them), or get to the 2yr/8000 mile mark OK?

Just checked and the level is still over the Full line (they must have overfilled a bit..)

Used to ride a sports bike. The engine shared its oil with the transmission. Always used full synthetic after break in.

For those that have ridden such a bike, you know you can actully feel the difference between old oil that is dirty or has lost its lubricity. Change the old oil and you can immediately feel the shifting and operation improve. So, just because you supposedly can go extended miles between changes per the manufacturer's claims, doesn't mean it has no effects. Particularly, if your air filter allows dirt into the motor or you ride in dusty conditions.

For those reasons, our oil change mantra is "sooner rather than later."
