The postings regarding oil temperature I found to be interesting and informative. The following are temperatures I have observed in my Forney (C-90) on some of my flights this summer. It should be noted that I usually fly between 8:00 and 10:00 in the summer here in Arizona (Phoenix area). To uncomfortable temperature wise after about 11:00.
