Very low compression and piston and valve damage in such a short time? I think this engine had issues long before this flight.Who knows maybe someone thought the MMO would help improve engine performance and added it.
It is nothing more than an assumption and speculation that MMO was the root cause of this engine damage.
If I put MMO or anything else in a tired worn engine and the engine dies anyway its ludicrous to look at the fuel and factually conclude the red color of an additive was the cause of the engines demise, when in fact it was dead anyway.
Aircraft engines are required to be overhauled long before they wear out. This is mandated by law and tt before overhaul is usually 2000 hrs. They are not like cars where you can drive then in any condition, and do your own repairs. This engine lost power in flight, to the point where the compression was below serviceable level, likely by continued use of the product in question as was determined by the NTSB.
Or, maybe you think this is a conspiracy against Turtle Wax??
