Oil is CHEAP !
One of the common traits of this engine that seems to run throughout many threads and user sites and shared experiences is:
(a) Transalp engines will use some oil if run consistently over 5000 rpm for long periods of time.
(b) As the engine hours/mileage increases, this oil use also increases.
The engine seems to run well and consistently well into high hours and it's only at the very end of service life that oil consumption reaches unbearable levels.
This means, therefore, that one is well advised to check oil levels when on long trips with many miles at highway, motorway, freeway speeds.

One should check oil levels frequently in high hour/miles engines.....yes, even if you change the oil at frequent periods.
