Full SAPS Vs Ester??

.....it’s inaccurate and largely irrelevant of course.

Exactly!

Other than it’s inaccurate and largely irrelevant of course.

We all have our favorite group of synthetic oil but the favorable
properties which contribute to their rapidly growing use on a variety
of engine applications are uniformity and purity...That is what you
are paying extra for...

Quote Mobil 1
"Synthetic oil is not only refined but also distilled, purified and
broken down into its basic molecules. This process not only removes
more impurities from the crude oil, but also enables individual
molecules in the oil to be tailored to the demands of modern engines.
These customized molecules provide higher levels of protection and
performance than conventional oils."

Quote Amsoil
"Pure, Uniform Molecules Form Strong, Stable Lubricants
Petroleum oils have molecular structures that are randomly organized
and, consequently, have limited performance abilities. Their varied
and inconsistent molecular structure results in less film strength and
lubricity. Their paraffinic wax content also makes them more
susceptible to viscosity variance and cold-temperature flow problems."

I have no clue what any of that has to do with anything relevant to the subject. Maybe you do, maybe I’m just lost.

I just wish it was really that simple. lol

Synthetic Oil

Sorry to keep this off topic, but I can't let this often posted marketing drivel stand unaddressed any longer.

The oil film is not 1 molecule thick. The MOFT of a big end bearing under load is about 5 microns. That's 50,000 angstroms. The diameter of a C4+ saturated hydrocarbon, whether mineral or synthetic is 4.15 angstroms. The oil molecules tend to line up along their length under the shear forces in a bearing. That means the oil film at MOFT would be in the ball park of 12,000 molecules thick.

This will help you visualize the difference between the posted illustration and reality. Imagine that the single layer illustration is a piece of plywood sitting on basketballs. Now imagine the plywood sitting on a stack of "basketballs" 1.78 miles high.
