How much oil do rotary engines burn?
Oil consumption varies from RX to RX depending on how old the engine is, how it is driven etc. A general rule is around 1 liter per 1000 miles. But if you are doing track days, it is possible to use 2-3 liters for a day session.
Are rotary car engines good?

Why did rotary engines never catch on?
The fundamental design flaw of having a moving combustion chamber as on a rotary also means that part of each fuel charge is still burning when it gets fired down the exhaust, meaning wasted energy, increased fuel consumption and dirty emissions, not helped by the necessary total loss lubrication system which means oil …
What is the most powerful rotary engine?
