Studies show that as the oil goes through the engine, it will, at some point, usually see about 50° higher temperature than the oil sump temperature. This means that with a sump temperature of 245°, some of the oil will be at 295° at some point and that is too high. As for the OP, I will say that high oil temp in any airplane in cruise would be cause for landing. On climb in my TR182 with O-540, high oil temp in climb is a constant even with 9 quarts of goodness in there. Has to do with the way the oil cooler is installed. The oil temp determines my climb rate every #$%^&* time - even in winter. High oil temperatures in flight may indicate something as innocuous as a hot day or poor cooling during a long climb to altitude. Some airplanes just run a little hotter than others. Something may be wrong with the electrical system. High temp means hotter engine and hotter engine means lower oil pressure since it gets thinner with heat. Make sure you are using the correct viscosity for the temperature, and the oil level is good. As long as you're good there and the gauges stay in the green, you're fine. If pressure drops out

9 Feb 2014 A reciprocating engine is found to have excessive oil consumption is a possible indication of low oil pressure together with high oil temp. Critical cylinder head temperatures can be managed by leaning or enriching the mixture. “That airplane has two Continental TSIO-520s that are presently at about 205 “Historically, cylinders which continuously operate at higher CHTs, say, 400 “Typically, once the engine is broken in, that oil consumption will stabilize. Mobil Jet Oil 387 has been developed to meet the performance requirements of both using Mobil Jet™ Oil 387 turbine engine oil in its new Airbus A380 aircraft. Alcor Deposition Test, Vapor Phase Coker, Erdco High-Temperature Bearing Being employed in a position where several hundred as-removed aircraft oil of causing both a ruptured oil cooler and high oil temperature - probably in that generally caused a higher oil temperature rise in the engine and has made the use of oil radiators more prevalent in modern aircraft engine in- stallations.
High temp means hotter engine and hotter engine means lower oil pressure since it gets thinner with heat. Make sure you are using the correct viscosity for the temperature, and the oil level is good. As long as you're good there and the gauges stay in the green, you're fine. If pressure drops out
11 Oct 2018 If you suspect carburettor icing when flying an aircraft whose engine is not [C] This may be ignored if the oil temperature is high, provided that 9 Nov 2015 High oil temperature indications may signal a plugged oil line, a low oil quantity, a blocked oil cooler, or a defective temperature gauge. Low oil 19 Oct 2016 I've had wonderful luck with piston aircraft engines throughout my nearly 50 Since engine oil cannot survive temperatures above about 400°F, these “It's amazing how much a small increase in CHT can accelerate engine

High temp means hotter engine and hotter engine means lower oil pressure since it gets thinner with heat. Make sure you are using the correct viscosity for the temperature, and the oil level is good. As long as you're good there and the gauges stay in the green, you're fine. If pressure drops out Oil Temperature Maintain oil temperature in the 180 to 185 F range during flight. This range will allow moisture that has accumulated in the oil on the ramp to boil away during flight. When the aircraft sits on the ramp or in the hangar, the engine heats up during the day and cools down at night. If you look at the Type Certificate Data sheet for the O-300, it shows that the max allowable oil is 240 degrees instead of 225, IF you are using single grade oil, which you are. I've been around the O-300/C-145 since 1973, and high oil temps are a normal aspect of operating this engine in hot weather. the aviation superstore for all your aircraft & pilot needs | 877-4-spruce Home / Instruments / Oil Gauges / Oil Temperature Gauges 38 results for Oil Temperature Gauges On a normally aspirated Lycoming engine, the hottest oil in the system is typically about 50°F hotter than the oil in the engine oil sump. This is where the location of the sending unit may cause you to see a different oil temperature reading. For most engine models, an oil filter also requires an oil filter adapter. While the oil is cold, this system allows oil to flow through the oil filter without passing through the oil cooler. As oil temperature rises to approximately 180˚ F, the valve closes and forces the oil to pass through the oil cooler. There are three logical reasons why oil temperature could be high. 1. The engine is overheating because of some unrelated problem and that extra heat is being transferred to the oil. A common cause would be a long period of high power operation at low speed such as a climb to very high altitude at low IAS.
