thread89-169171: Question on Deep Sump Cooling
Doing this modification to a 2006 URAL 750 cc 40 hp engine did show a 10 degree F. decrease in stabilized running oil temperature. Temperature was measured with a bimetal dipstick dial thermometer. Temperatures were (Fahrenheit) 312 degrees standard sump & 302 degrees deep sump. Tests were done under very similar environmental conditions (barometric pressure, ambient temperature, relative humidity). Engine was run in each configuration at 55 mph for 1 hour at 83 degrees F. Temperature readings reached maximums at about 35 minutes and 50 minutes, respectively.
The greater surface area created a approximately 3% decrease in maximum oil temperature in the sump.
No head temperature readings were taken.
CONCLUSION: Oil temperature is not SIGNIFICANTLY reduced with the deep oil sump conversion.

Deep oil pans are usually for control of oil/windage, increased capacity, etc. more so than just cooling though they may be advertised as such.
If truth in advertising could be enforced we'd need tens of thousands more prisons. <LOL>
