Well my wife's new Outback has an oil temp guage so I can't obsess out weather to use 20 30 or 40 grade oil so much. If it runs cool I'll give up my dreams of running 0w40 M1!
2016 Outback oil temp

Now you can tell how different grades affect running temp.
Good point now I have to run all three!

Highest so far was towing with an empty utilty trailer
Hit 246F or 248F momentarily.
That is a bit higher than my wrx. I typically see 208 as my maximum highway temp. Hit mid 230's during a track day last fall. That is the highest I have seen.

FB25 4 cylinder in my Outback. Its been about 105 outside so I can't wait to check it tomorrow afternoon.

I think Inspecktor's point is that it won't. It would be more appropriate to base your oil viscosity requirement on oil pressure.

Oil-to-coolant heat exchange on the FA20DIT. As far as I know, the FB25 doesn't have an oil cooler.

You sure it's not a dummy gauge like Ford's oil pressure units?
Thank goodness! I thought this was another OMGmyOil Is so HOT thread.

It's a real gauge with a readout via the Multi Function Display. Do a google image search on 2016 Outback mfd oil temp.

Well going to dinner at 6pm 103 degrees outside, oil temp hit 219. It cooled down to about 210 in town. 270 miles on car.

My oil temp runs the same. Our 6MT have high revs on highway.
My Edge CTS gauge reads the same as dash readout.
No oiler cooler on fb25.
OP, your oil temp seems normal.
I'm using Mobil 5w-30 EP in Summer. Mobil 0w-20 EP all other seasons.

600 miles on car now and at 80F outside the oil was running 224 constantly. On about 5 miles of an 8% grade at 65mph it ran up to 240F. I'm not liking how quickly it climbed. I'm wondering if it would have gone higher if the grade were longer? I know most synthetic oils can handle up to 300F but I'm starting to worry about my 0w20. If I actually drove long distances through mountains and I'm going to be approaching 250F I think a 30 grade oil might be better? What do you guys think?

0W20 is working fine , but in terms of margin of safety in engine wear protection , my inclination
is for xW30 (for its higher operating viscosity) in your circumstances.

How about heavier grades producing slightly higher oil temps.

Sure , heavier grade of say 0W30 may produce higher oil temps than a 0W20 , as it 'should' be
the case .More so when both scenarios encounter same levels of boundary lubrication regimes in
the engine operation.
Having said this , I estimate viscosity of a typical 0W30 at 252F could be equal to the
viscosity of a typical 0W20 at 240F.
More over , HTHSv @150C of a typical 0W30 (API specs minimum 2.9 cP) should be higher than HTHSv
@150 of a typical 0W20 (where API specs minimum 2.6 cP)
Hence , higher margin of safety in engine wear protection .
Well , OP would be in the best position to validate oil temps of xW30 and/or 0W40 under best-
effort identical conditions for real field results for comparisons and evaluation.....

I hit 242 degrees going up a long grade today. The car had 5 passengers and no gear. I know 20 grade is fine at that temp but I don't like how thin it it as those temps... It was only 75 degrees out. The manual does state that heavier oil may be needed in high heat, I see a stout 30 grade in my future.

Thanks for sharing , Red.

Very true, if I was rational.
