Went to the dealership for some routine maintenance today and got an oil change. After I left i realized that they didnt put the sticker on the driver side windshield stating what kind of oil was used, next mileage/month that the oil needs to be replaced

I called the service dept. and they told me they dont provide stickers with that info. That the car would tell me when it's time for the next oil change. I know that the default setting for the car is 10,000 miles

Call me old fashion but I believe the oil should be changed every ~3 months or 3-5k miles. Not 10,000 miles

Does anyone else have a similar situation? What do you guys do?

TLDR: Get an oil analysis kit.

So the oil definitely doesn't need to be changed every 3 months unless you have crazy high idle hours, like over 750 hours of pure idling or just redline the motor all day.

The engines are 100% designed (The PR25DD engine which is from Nissan) to run a bit over 5 quarts of 0w-20 full synthetic for 10k miles under ideal conditions. If you have lots of idle time, high revs or load, drive in extreme cold or heat then according to Mitsubishi / Nissan should change oil on the PR25DD engine at 5k miles.

Oil is completely different today than it was when 3k mile oil changes were the standard. Modern oil of good quality like penzoil ultra, mobil 1 extended performance, or amsoil signature series under ideal conditions will provide great protection to around 20k miles. Even some modern filters are guaranteed to 20-25k miles although I would keep these to 10-15k miles as these filters can break down. But those insoluble fibers of the filter can be found by testing your oil with a lab.

UOA - or Used Oil Analysis' are available pretty cheap. Oil Analyzers is the preferred oil lab for amsoil, you can order the test kits directly from Amsoil.com for $30. Blackstone labs has been the defacto gold standard and cost $40 if you include TBN (total base number). Oil Analyzers included the TBN for $30.

If you are actually concerned about what is going on with the oil and the motor getting one of these test kits and submitting the oil for analysis will give you non-anecdotal real data about things like:

Wear metals from bearings (this is the thing that really tells you about your engine health)
Fuel dilution (Direct injection cars suffer greatly from fuel blow by which thins out the oil in the crank case)
Oil Additives (Things like zinc and phosphorus and other items that act as detergents and dispersents. Tells you how well the oil is holding up)
Viscosity at temp (Oil in typical gas engines will thicken over time, this will tell you how the oil is wearing)
TBN (The base number of the oil, as in base vs acid, oil can become acidic over time)

I'm a big fan of data and using data to drive decisions. I just submitted an Amsoil 'Oil Analyzers' UOA test kit for my 2020 Jeep 3.6 because I'm extremely curious about the state of the engine. It only has 14300 or so miles but the wife drives it 1 mile to work and back so it never gets up to operating temperature. Without a good amount of time in operating temperature the fuel and moisture in the crank case will not burn off via the PCV. I imagine the oil is full of fuel and moisture and the only way to tell whats going on is the testing.

I have a kit ready to go for my 2022 Outlander, I'll be dumping the factory oil in the next week and putting in Amsoil SS 0w-20, currently I have 850 miles, the factory fill will be dumped around 1k miles. I also have 4 quarts of Amsoil CVT fluid I will swap in but I will hold off on sampling the CVT oil until maybe 5-7.5k miles.

And just to be oily inclusive, you can test oil for just about anything with these labs. If you have a lawn mower, air compressor oil, hydraulic oil, transmission oil, differential oil, just about any of these can be tested. The data returned will tell you things like high concentrations of lead exist which lets you know that large lead lined bearings are wearing. Anyways. Just don't dump your oil at 3k just because, use data to drive decisions.
