Nothing unusual for many many cars and trucks etc. that the oil/water temp gage is an indicator only. Too many people would go nuts if the needle climbs over "normal".
Recently in Germany my rental VW Passat Diesel had the exact oil temp read out in the MF screen, man, that thing got hot when flooring the pedal on the autobahn! Water gage was reading " normal" and the digital oil temp readout showed north of 98 Celsius and more! In town or cross country never more than 80 C.
Just saying'
