I do my yearly oil change 2011 RAV4 (2.5 4-cyl) every fall. I use whatever synthetic 0 or 5W20 is on sale. There is Quaker State UD 5W20 in the sump right now, changed October 2017. This vehicle is driven only a few thousand kms per year, and I've put around 2500kms on the oil. Winter seems to have hit rather early this year, and I was wondering if I should just stretch the OCI until the upcoming spring? That would stretch out the OCI for 1.5 years, something I have never done on this vehicle before.
Leave it in for 1.5 years?

I've gone over two years with the oil in my work van.
Your engine will be fine to change in the spring.
Less than 1,600 miles in 13 months on QSUD? Go for 18 months. I've done it in my Ridgeline.
I've gone 3-4 years without an oil change on some rarely driven cars, and that was on a syn-blend not a full-syn oil.
I have an old Farmall Tractor that's had the same 15W-40 for over 10 years now.
I start it once or twice a year, warm it up, work it hard for 1-2 hours, then it sets till next year.
The oil still looks great, and I bet it would pass an analysis easily.

I've gone 3 years on low-duration OCIs in my cars, truck, tractor.
You'll be perfectly fine.

Whenever you decide to change that oil, please PLEASE send it for an UOA and post it here.

Only a UOA will tell the truth but I'm with the others here. Time in service is not so important.
A fee to use this site should fund "extreme circumstance oil analyses". This is how we get smarter.
Flame suit on AND I'm in a bunker.

Agree the oil should be perfectly fine at that distance. If you are concerned - take a sample now to be certain.
Depends on the types of trips it gets.
If you are doing a lot of short trip driving, you may have a high moisture content, and can lead to milky oil.
I was planning on doing year + oil changes in my truck. I do mostly short trips (my drive to work is only 3 miles), but do at least a monthly drive to my mom's (50 miles highway each way).
My truck also uses a qt every 1500 miles, so I figured I could do 2 years (maybe 8000 miles) without a change.
When I was adding oil one day (about 2 days after a 100 mile drive at highway speeds), I found this:

So I changed the oil that day.
