It would help with it believe.

They send you a breakdown of all the elements found in your oil with percentages, and then tell you what each of the elements shows...

Silica/Silicon is a listed element.

On my 2.5L the Silicon readings were always right at the normal range.

Zircon is not a specific thing they look for.

Most likely it would just show up in the insolubles table as a parts per million count.

You might be able to ask for it to be a "counted" element???

However if these small granules are visible to see they'd never make it past the oil filter. That or collect in low pressure areas like the heads maybe.

Makes me want to cut apart my filter at the next oil change...

On the diesel sites I visit daily. Most of the owners send ther oil out for analysis and they cut apart there filters or send them out too. the first few oil changes alot say they get high silicates readings in the oil, but after break in etc they drop off alot. I know the fuel filters are always nasty though I think this would be an excellent idea to check filters and oil.

I was told that it would not make it all the way into the filter.


With that said - Even if it did it would be passing through the entire system to get there.

That would make sense if the problem is after the filter location in the oil gallery and before the oil drains. (which feed the pan/pickup)
That means this material could defintely do it's damage before it circulated back to the filter. It it even made it that far without collecting somewhere.


Now the hit to miss rate must be extremely low but even still that's a crazy thing to "miss"
