Do we actually think the engine will fail sooner (due to miles/usage) using Amsoil versus Pennzoil? This is the question that should be asked and answered.
Except maybe the people who complain about them...
Having previously lived on a Florida cattle ranch, I can unequivocally state that no, they do not squat. They walk around doing their normal bovine stuff, and poop just falls out of their butts, frequently while walking to and fro.
Q: Does a bull squat when it drops a loaf ?
It is for testing the health of the oil and to a much lesser degree measuring wear. A UOA is to check fuel dilution, viscosity, additive pack health. oxidation, nitration, and the like. It is and never has been a "wear gauge".
Doesn't matter if someone doesn't believe solid data. It's true whether they like it or not.
Interesting question, can you describe what is included in the word failure here ?
The question is: why invest in equipment to measure or even include the wear number in the report if the information is irrelevant ?
Yep. Regular oil and filter changes on a reasonable schedule will likely have the engine run fine until something else fails, barring any statisical outlier.
Because a sudden rise in contaminants will inform you something is going wrong before it fails.
I agree, I find OCI to be far more important, then viscosity, and finally what additives the manufacturer included to affect viscosity at temps high and low, and deal with wear, carbon, etc.
How do you classify GM changing oil viscosity as band aid to their engine issue ?
I didn't know they had an issue
That was just one example. I don't have to give an exhaustive list for my point to be valid
