F150 oil capacities

[zenoahphobic]

Leave ice in your freezer long enough I will "evaporate" without going thru liquid phase due to below freezing temperature in the freezer, the everyday example.

Your not a climate change sceptic are you?
It's not rising temperature melting the polar ice; it's just evaporating!

What might be missing here it matters not what the oil level is when the engine is stationary but what is required when engine is running plus a reserve amount. Oil stays in circulation when the engine is running, lots of it. The higher the viscosity the more sticks around.
So the question might not be a change in the oil reservoir holding capacity, but change in pooling capacity elsewhere in the engine.
Unless someone can confirm a change in engine design (include position of dipstick marks), I believe the difference is purely arbitrary.

Try both sticks in the same engine to see if they read the same. Why,.... why not.
