The seal thing has be solved since about 1995.
It's solved, unless you put a MASSIVE turbo on it.
As for burning oil, If you burn diesel, your fuel is your lubricant.
The remaining problem is the narrow operating range.
This is not an issue for drones or ICE-Electric.
Ex: austroengine.at/en/products
However it means the engine operates at a constant RPM, and does not go "VROUM VROUM".
It seems people want this noise more than light weight, economy and reliability.
At least that's what the marketing departments of car makers say.
But they have all been infiltrated by Clarkson.
The bastard.

Interesting stuff.
I know oil is used as a lubricant in two stroke engines, but I thought in four strokes it affected the efficiency.
Having said that, I had Honda VTEC that used to drink oil but apparently that was normal.

The big difference between modern engines
Is how you run it:
An engine built to run at a constant 750 Rpm (to produce 50Hz) where only the load varies,
is far easier to fully optimise than having one with a power-band of 500 to 1500 Rpm.
For one, I cannot comprehend why hauling vehicles are not diesel electric.
Apart from the sector being traditionalistic.
