Oil temp: 55





That's too wide a variation. On my EI US8A, digital oil temp and OAT
I had in my 182 all CHT's, EGT's, OAT and Oil temp were within 1 degree.



Mine are all within 1 degree if the engine is cold, However if I have
the engine preheat turned on (I have Reiff cylinder and sump heat),
there is usually a bit more variation. I think he said that he had the
tanis heat on.



I have sump heat only. With the heat on and the Kennon nose mitten on
the temps are still the same. Every CHT and EGT is 80F and the oil temp
is 100F, it's like July in there. That's a **** poor system if you're
only seeing mid 50's with a Tanis running.
