Other than you , who said sediment?

No one.

All oil has contaminates in it, that is part of why you change it. It will settle out if left to sit long enough. Change it while it is hot and it doesn't have time to settle out.

You mean when you pull the drain plug,and have to stick a screw driver in to get it to drain sediment?

One thing not brought up is doing it differently on our 45 year old junk vs or new stuff.

The newer rides are so efficient, outwardly the oil coming out looks the same at 30k miles as it does now at 130k miles.

Ever pull a valve cover off a newer car with 100k miles and think, wow this is clean.

Which obviously is not the case with our older junk.

Do you think the newer oil is the difference, not the car make and model? I do
OP, I have work on cars for a long time starting in service stations as a teenager when we serviced the cars back in the early 1960, hot oil drain is the best

Solids, contaminants or sediment, is a all academic.

Words mean things.

Sediment - Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles.

It's not academic. If you have sediment in your oil your engine is [censored].

Engine oil pan including sediment basin and baffle configuration
US 6237720 B1
ABSTRACT
A sediment basin and baffle combination for internal combustion engines, which combination includes a sediment basin in the bottom of the engine oil pan for accumulating sediment and contaminants from the engine oil and a baffle positioned over the sediment basin for limiting re-entry of the accumulated sediment back into the oil reservoir from the sediment basin. In a preferred embodiment the baffle includes a baffle grid constructed from one or more layers of elongated baffle elements, each having a triangular-shaped cross-section. Each baffle element is oriented in the baffle grid with a triangle apex of each baffle element facing upwardly to promote drainage of sediment and contaminant deposits through the grid, into the sediment basin and a triangle base of each baffle element facing downwardly toward the sediment basin to retard sediment and contaminant re-entry into the oil. In one embodiment the elements of one of the grid layers are disposed in perpendicular relationship with respect to the elements of the adjacent grid layer or layers, and in another embodiment the single-layered grid is characterized by multiple, intersecting longitudinal and transverse baffle elements provided in a single plane. In still another embodiment the baffle is characterized by a baffle grate having at least one layer and preferably, two layers of parallel baffle elements, and the baffle elements of one layer are staggered or offset and parallel with respect to the elements of the adjacent layer or layers. In a most preferred embodiment the sediment basin and baffle combination includes a baffle ring that overhangs the sediment basin and, with the baffle, retards sloshing of the basin sediment back through the baffle, into the oil reservoir in the pan.
