I had 1-2 ppm's of Tin in my last sample, not sure what parts contribute to that reading, maybe it's from the oil cooler. That is an interesting reading though, and I've never seen it that high.

 

why you all gotta scare me now? lol

wonder if blackstone would have any idea as to the high tin ppm?

 

Do a virgin oil analysis if you are concerned enough. That is the most likely source. Blackstone might even do one for free for you if you ask.

 

Here is a link that might help explain the Tin in your UOA. But it's not definitive.

Thanks for the link Indymac, Evils2k, I wouldn't sweat it, it's not like it comes from a major part of the engine like bearings or pistons or rings. It could partly be an additive, and perhaps partly from something else, which at the end of the day is likely harmless.

 

When I think of tin in an engine, I think of bronze (a copper alloy like brass but with more tin for greater hardness/durability).

Question is, what parts of a S2000 engine use bronze? In some engines, bronze is used in valve guides ... but that sounds pretty old-school to me.

Even so, the copper/tin ratio is incorrect. Should be something like 6:1, copper to bronze but the wear metals here are just the opposite.

Odd.

 

yeah I also thought of a bronze component, but I can't think of any specific part that's why I'm thinking of possibly the oil cooler. Would there be a part that is has bronze welds on it ?, bronze is pretty soft for the most part.

 

Thanks for all the discussion guys. Definitely good info in here.

I also got an analysis done for my Mazdaspeed Protege but I doubt anyone wants to see that hahaha

 

always got time for a new uoa

 

Alrighty then....here ya go.

I was surprised by this one...I expected more wear on the FSDE-T than it showed due to the mileage and how rough I've been on it over the years lol
