I no longer change the oil myself on my ATD vehicle, due to an auxiliary filter. Whether that's a good thing remains to be seen. However, I would never pour ice-cold oil into a hot engine, for the same reason as with coolant.

I highly doubt whether using a bypass filter is a good idea for the ATD system.
Since a hydrocracked oil is being used here, the high pressures are essentially reverting the hydrocracked oil back into a conventional oil.
Similarly, the base number of the oil should be checked to ensure it doesn't become too acidic.
Similarly, what about the up to 7% biodiesel in gasoline? Does that mean you need to regularly check your oil for fuel dilution?

Furthermore, if you change the oil with a hot engine and then add oil that is not suitable for normal operating temperatures, you may have drained the old oil too early.
Warm up the engine normally. Wait 10 minutes until all the oil has drained into the pan. Open the oil filter and drain plug.

Then put some "simple" 15W-40 oil in the freezer at -15°C. I doubt you really want to start your car in winter with that .
If the 15W-40 oil were completely free of additives, it could at least be used in classic cars with bimetallic bearings.
