SOT: oil change interval, newer car with full synthetic Options

[fixer34]

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..)

Two studies over 20 years ago switched me to synthetic. SAE used to have a monthly publication (maybe they still do). This publication was full or articles and real world tests. I could find the magazine in the School library at Michigan State when my wife was doing Graduate work.
Once study was on over the road trucks and rear differentials . They split the fleet in to two groups. One got synthetic the other got regular dino oil. Both were same grades and specs. They dissembled the differentials every 100K miles and measured wear and changed the fluid. the test ran for 10 100K cycles. At the end of the test the synthetic trucks had less wear on the differential than the dino oil at 100K.
Second test was on a fleet of taxis. one group got synthetic other got dino oil. At the end of the test the synthetic went much further between need to rebuild the engine but it was determined there was no economic benefit as the added cost of synesthetics (at the time) over the life of the vehicle equaled the cost per mile for earlier rebuild. For most people the longer life would be a benefit.
Those to articles convinced me and I have only used synthetic since then. I have also done some of my own experiments an test and validated synthetic as the only choice.

That said , I would not have any problems with 8K change interval with synthetic on a car that is driven regularly. My only exception is that I think its a good idea to do an oil change on a new car (or rebuilt engine) when you have around 1K miles to get rid of all the debris from break in and manufacturing.
