    desired oil temp

    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...
