The oil itself shouldn’t evaporate but the moisture and or fuel that gets in it. If your running a none synthetic oil the lighter molecules can evaporate off which leads to slugde and high oil viscositys. But knowone should be running dyno oils in these trucks.
More blow by is created when you work the engine hard. There is also more air being moved through the engine so more moisture content. Plus the higher engine temps mean more can evaporate out the system. Multiple reasons why its good to work the engine hard from time to time and get it up to...

How much a catch can well catch depends on the usage of the vehicle. On mine this is what I drianed out of mine after 1800 miles and a long tow. Thats a lid off a spray paint can for reference.
