It's not a break-in or oil type issue. More important to report would be your ambient temps, cruising speed and RPM, altitude, and A/C on or off. You live in Canada!

Before my oil cooler, I could easily highway drive in the Midwest with temps at 210F even on an 80F day. But then immediately stop in traffic and that illusion quickly disappeared as airflow into the engine compartment became stagnant.

Your next 80+F day, go drive around for a while to get the oil up to temp. Then do some hard pulls up to 5-6k and then stop dead in traffic. Do some stop and go for 10 minutes with a few revs to 4k in between (stop light to stop light). To exaggerate things, keep your AC off too (the compressor turns on an auxiliary fan that drops oil temps about 10-15F). See where those oil temps end up.

Mine was pegging 270 at the track with a cooler. As soon as I pulled off, I was back down to 190.

95 degrees in Omaha the last two days (installed my Stillen 19 row Saturday) and I have yet to see above 205...and believe me I tried. Before hand it was 225-230 just normal driving in 75-85 degree heat, and in similar heat as the last couple of days it easily would have been pushing into 240+

On a few occasions mine pegged 220F on 85F weather!!! This is 20min drive home from work on the freeway. Then on other days where it's over 95F on the same drive, I barely hit 210F. It's weird. My driving style is the same which is pretty conservative (23.7 MPG). What's also weird is with the hot temps 50% throttle in 1st and 2nd feels like 6th. Car won't budge.
