To the list: Since adding the El Reno oil filter to the C-85, I have had some requests as to any improvements in lowering the oil temperature, so I will update with info. from this last week. With OAT of 90 degrees and normal climb and cruise the oil temp ranged from 175 - 205 for a 1 hour flight. Today with OAT at 80 degrees, max oil temp was 195 again after 1 hour. On approach to landing it will decrease to about 160. So far this appears to be about 10-15 degrees cooler than without the filter. The filter was added for better filtering, but the cooler oil is an added bonus. I personally don't like to see the oil temp above 200, although I guess its allowed to reach 220 or 225 max?
