Keep her above 4000rpm and she'll thank you for it every day.

SisuDiesel engines. In practice, the Valtra N111 EcoPower model means significantly lower workhour costs, environmental friendliness and low
emissions. An added benefit is the reduction in engine noise by 4-5 decibels.

Engine wear and economy are two totally different things. Slower motion definitely decreases the energy required to move the parts around. I'd like to see the proof here of extended engine life.

That is not the issue under discussion. The issue is, is running at high RPMS GOOD for your car.

That was the contection.

Show me proof that it is GOOD for your engine.

Thanks

Question-If running your car at high RPMs were GOOD for your car, why is this condition considered as "severe service" by most manufacturers and generates a recommendation for more frequent oil changes.

If it were GOOD for your engine, they should tell you to run the oil a lot longer. RIGHT?
