Hartmut, I have to agree with Larry on this. My oil temp is normally 170 and in order to get it up to water boiling point, I throttle back and put the Coupe in a steady climb at 75. This always gets the oil temp up where I need it, Pete -----Original Message----- From: MAGIC VAC [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 04, 2002 3:08 PM To: Gordon Tanner; [EMAIL PROTECTED]; [email protected] Subject: Re: [COUPERS-FLYIN] Slowest Cruise Speeds ----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- I have to agree with this assessment Hartmut. In slow flight, your engine will be working harder just to maintain altitude. Once you drop a few hundred rpm, you have to increase the throttle just to maintain that lower rpm setting. Kinda like walking on a treadmill. Increase the climb angle, and you work harder, but you're still just maintaining the same altitude.
