Yes, that is part of the grand design. Out of curiosity, I've asked several dealer SA's how this function works but haven't gotten a definitive answer. It's possible that the N55 has some kind of split sump where the oil level sensor is located and the engine rpm is increased so a scavenge pump can fill the part of the sump where the sensor is located. One SA told me that the oil level sensor measures oil level by the amt/volume of oil pumped thru the sensor in a set amount of time and at a set rpm. I guess that would work, but I think the flow would be affected by oil viscosity which is gong to change due to a number of factors (fuel dilution, temp, length of time oil in service). I don't really know. Anybody know? Anybody care?
