Your turn: How come you assume the original poster is a liar?
"What seal?" Beats me. Probably the one that made this dude's car go from eating no oil to eating 1 quart every 200 miles. Something, somewhere must have failed. So what's YOUR theory on why that happened? Yeah I know: "The original driver is lying." That's a depressing attitude to have towards your fellow human beings.
I didn't say the OP was a liar. I said the story from the mechanic didn't make sense. It doesn't.
I also gave my take on what happened in this post:

Other people were accusing the driver of lying.
From what I read: Sometime recently (Fall 2012?) the engine suddenly went from running 5,000 miles with no oil consumption to consuming a quart every 200 miles. I don't consider this the fault of the driver (or mechanic). It's the fault of whatever went haywire inside the engine.

Saying the story doesn't make sense isn't necessarily implying he's being dishonest. Food for thought.....
I doubt anything went "haywire". Maybe it broke a ring that resulted in oil getting into the combustion chamber and burning? Perhaps it in fact DID have an excessively rich condition due to something like a stuck injector, resulting in cylinder glazing, ring sticking and fuel dilution, making the lubricant more volatile, allowing it to burn off quickly.
There are all kinds of logical failure models here. Just none of them have been described by the OP.

Well aftyer reading other threads in this forum, like the Honda 3.5 engine that had 7500-mile synthetic oil changes, and yet still sludged at 80000 , I am noticing a pattern:
In that thread, this thread, and other threads, the driver always gets blamed. "The driver is lying" is the typical response across all these threads. Only a few people put the blame where it belongs (the engine).
Of course if a driver does abuse an engine he deserves blame, but I'm not seeing that here. 5000 mile changes with Mobil 1 shows the driver followed a good schedule. One little 20k experiment with Delvac1 would not make the engine die 5 years later.
