I submit this information from the Manufacturer without comment:

From the Manufacturer: Cool Collar Lab Test Results:
Test Results Laboratory Test
Castrol GTX 10W30 motor oil was heated to a temperature of 220 degrees F. and pumped simultaneously through two identical oil filters. One oil filter had a Cool Collar attached, the other did not. A fan was used to direct seventy degree F. ambient air over both oil filters at a velocity of fifty miles per hour. The oil exiting the filter having the Cool Collar installed indicated a Aheat removal approximately equal to two degrees per minute. Whereas the oil temperature exiting the filter without the Cool Collar showed no change. (Typically an automotive engine passes all the oil through the filter more than once per minute).
Summary: With a constant heat source applied to the oil, the temperature dropped to 202 degrees F (from 220 degrees F.) with five minutes. This translates to a 12% temperature decrease of the heat added to ambient temperature.
Liquid Cooled Automotive Engine (Road Test)
This test was an actual highway test. The car used was a late model Corvette equipped with digital readout oil temperature and coolant temperature gauges. On a 72 degree F. day, at 65 miles per hour, the oil temperature read a constant 221 degrees F. The water temperature was 195 degrees. The corvette was then pulled off the road and a Cool Collar was installed. Testing was then resumed. Within a distance of five miles the Cool Collar was responsible for lowering and maintaining the oil temperature at 203 degrees F.
Summary: Our tests again indicated a 12% approximate reduction above ambient temperature of oil heat. On similar testes, it was found that after installation of the Cool Collar the oil temperature will typically drop near to the level of the engine coolant temperature.
Air Cooled Engine (Road Test)
The test vehicle used was a 1978, 911SC Porsche, equipped with a carrera style oil cooler. The car was driven 65 MPH on a 85 degree day for approximately 35 miles. The car was then stopped and a I.R. thermometer was used to check the temperatures at various points along the oil lines, tank and cooler. In addition, the reading on the dash temperature gauge was noted. An average temperature of 220 degrees was logged.
Testing was then resumed, with the Cool Collar installed on the oil filter, over the same coarse and speed. At the end of the 35 miles the temperatures were then checked again using the infra-red thermometer at the same points as before. The indicated temperature readings showed an average reading of 208 degrees, a reduction of 12 degrees.

Many people have confirmed these results using their in-dash gauges. Has anyone actually done a repeatable test like this?
