Hi Neil,
Check with Brian, see what his Savannah sits at.

Neil, hi.

I've never seen my Savannah having an oil temp over 95 centigrade, even during summer with outside temperature over 35 and while climbing. Maybe a clogged oil radiator or a faulty thermostat if you have one installed?

Hi I have a Savannah VG in New Zealand. In the wintertime I blank almost all of the oil cooler. My temps run up to 120 in an extended high power climb at low airspeed and then settle down to about 90/95 in cruise, depending on OAT. In summer I adjust the blanking to maintain similar temps. IMO it's good to get the temp up over the 100 degrees or so every flight but I wouldn't want to see 120 in cruise if that's what you have.

Thanks. It’s only in the climb that I get 120°. Cruise is about 110°

Your oil temp at the photos are rather high, but the CHT are low. When I had a similar problem in my other plane, both oil and CHT temps were high. Of course at that installation I have a 914 and the oil cooler was rather small for the turbocharged engine, so I installed a bigger one and the problem disappeared. In a Savannah, having oil temps about 110 during cruise is still in the greens but it seems higher than normal. In my hangar we have 5 XL's and two VG's and no one sees temperatures over 95 during cruise. During extended climbs no more than 100, 105 max.
