The concept is pretty simple if you think about it. Shortly after startup all of our M96 moving parts are ideally floating on a thin coat of oil. Minimal metal to metal contact, minimal wear. When you put a heavy load on an engine at low rpm such as hard acceleration or climbing a hill you risk exceeding the ability of the oil to continue floating the parts and you get metal contact and excessive wear. Because the oil pump is tied to RPM, the lower the RPM the slower the oil replenish. When the engine load exceeds available oil replenish damage is done.

The severely lugged engine (bucking bronco) has gone far beyond overloading available lubrication, bearing surfaces are all on metal, and the motor will not turn over well enough to enable complete combustion causing detonation and further engine damage.

The simple solution is downshift to increase your oil replenish rate, float the internal moving parts and support the increased load. Our motors seem to be more sensitive to low RPM loading than most so unless I am at idle, coasting downhill, or approaching a stop with no engine load I rarely run my RPM below 2000.
