The only way to know for sure is to do a metallurgical analysis of piston rings.

"Steel contains about 1% manganese, and the Manganese is efficient in boosting the quality and functionality of the steel. Manganese-steel combo contains approximately 13% of Manganese. It is extremely solid and is used in the manufacturing of rifle barrels, railroad tracks, and jail bars."

Uses of Manganese - All Uses of

Manganese is a highly metallic element which is known for its high electrical conductivity. Manganese has a nomenclature of 25 in terms of atomic number, and it is symbolized by ”Mn.” Being the fifth most plenteous metal in nature, Manganese is very reactive when mixed with other metals. For...

But if it came from the steel parts of the engine, wouldn't we see more iron, or even glitter in the oil or filter? after all only between 1 and 13% of the steel is manganese. so 7ppm manganese and 100ppm iron wouldn't be a surprise.

Saying it is proof of anything is ridiculous.

Was the manganese level of the fuel checked before and after?
Was the testing of the manganese level in the oil samples double checked, before and after?

I’m thinking no.

And was it one data point or many?
