To day I drive a spark ignition engine.
I have driven the compression ignition engfine in the past.
There are two distinct different methods for driving these two different machines.
Simply putted: A spark ignition engine(gasloine) is driven with the throttle position from the top down. The very soft pedal to reduce the combustion chamber pressure and give longer engine life and decreased fuel consumption.

The compression ignition engine(Diesel) is driven with the pedal from the bottom up. Full throttle to obtain power and forward motion. As the speed builds you relax the pedal toward the top and the cruise position.

Your driving technique is holding with a diesel engine.

Your crankcase blowby is a different matter. You should have a cylinder leak rate performed, this may help isolate your problem; if you really have one.

Larry told you right in oil consumption rate, you don't really have one.
