I read the Elephant Motorsports article that was linked. It's simplistic. There's 3 kinds of lubrication in the engine, hydrodynamic (bearings), thin film (cam and rockers), and combo of both (rings). The article deals with hydrodynamic only, and then doesn't allow for the fact that you can...
Air cooled guys don't get excited about 250degF oil. If my oil hit 250, I'd put the car on the trailer and head for the beer cooler. There's a range for what is acceptable, and as long as you're within reasonable limits you're probably ok.
I've configured my oiling system a lot of different...
And another thing....
There's no ideal temp, but there's an ideal range. Here's some variables to consider.
Optimum viscosity at temp. An oil's "Weight" XwY describes it's cold (0degC) and hot (100degC) viscosity. X is cold and Y is hot. The curve of visc vs. temp is non-linear. Temp...
Generally when a person asks about oil temps, they're ultimately comparing their engine with someone elses.
I race an '87 BMW and have collected a lot of data on oil over the years. One of the things I learned is that oil temps can vary more widely than would would expect, depending on exactly...
