Operating Oil Temp

I was correct, so who feels like lighting up a motor!

I have never heard of this! The Lowest "Flash Point" of Mobile One oil I have see is around 430 degrees Fahrenheit. I certainly don't want my oil to flash! Please explain this Flash phenomena to me....

olive oil has a low flash point of all oil's. I was curious what he said about the flash point being where the oil starts to work. I called the state fire Marshall and asked him what oil flash point means.

flash point


[paste:font size="5"]DefinitionTemperature at and above which a liquid gives off enough flammable vapor to form a mixture with air that can be ignited by contact with a hot surface, spark, or flame. Lower the flash point, greater the fire hazard. Common test methods of determining flash point include Pensky-Marten Closed Tester (ASTM D93-79), Setaflash Closed Tester (ASTM D3278-78), and Tag Closed Tester (ASTM D56-79). Since each test method may yield a different reading, the test method employed is usually indicated when a liquid's flash point is given in a material safety data sheet (MSDS) or in technical documents. Flash point should not be confused with auto-ignition point temperature at which combustion occurs spontaneously, without an external source of ignition.

Yes... You are correct, the Flashing of oil is just that... the process typically starts at 190*. Ideally you would want to see a temp of 220, at that temperature its able to burn off all of the deposits and accumulated water vapor, since water boils at 212*, if you cant get enough heat into the oil, yours technically contaminating it with water vapor, what does this mean... Well, add moisture to all those moving parts, bearings, etc that typically get lubed by the oil... You get my drift, moisture BAD... Oil Heat GOOD...

With that being said, different oils have different characteristics and max heat temps at which point they start to break down, a safe oil temp can be argued between 260-300 depending on synthetics and other characteristics, either way, extended during at the high end in temps breaks the oil down.. Because I would think most of us run a synthetic, most synthetics are good to 300* before they start breaking down..

Either way, Oil Temp is good, you need it in your motors to actually protect them... There was an article I read that stated for every pound of fuel burned in an engine, the combustion process also generates a pound of water...

Anyway, food for thought...

Ok, so I think the readers digest version would say "keeping the Oil temperature above the boiling point of water gets rid of unwanted moisture and normally occurs above 212 degrees fahrenheit".
