higher fuel flow in hot weather?

[207WF]

I just got back from an 11 hour multileg trip around California. It has been very hot (over 100F on the ground, 77F at 9500 feet), and I had to reduce power quite a bit in the climb for oil temps. Even with so much time at reduced power (30-40 minutes to claw my way up), and then using my normal cruise power settings(more throttle then I had on in the climb) my fuel flow was 5.6 gph hobbs. Normally, I see only 4.6 gph. Should I be worried, or could the hot temps do this? WF

I'd guess you burned most of it clawing your way up.

But the throttle setting in the climb was lower than in cruise! WF

Trying to climb out from N. Arkansas (Walnut Ridge) after Oshkosh I hit 31C (88F) air at 5000 feet. One of my CHTs read 239 F and stayed there even in cruise. Never had this problem before the hose replacement. Oil temp never got over 210F. Would this be expected?

I think I heard that there is a new end on the sensor wires that grips the sensor better. Has anyone else heard of it? I think I heard it from Lockwood. I'm looking to perhaps but new ends on this winter when I go over my plane.
