I'd appreciate a follow up when info is leaned & what type of engine failure it was.


Thinking more about this, testing companies generally test the parts per million of metals in the oil, knowing what might be normal wear, or excessive. They also can check for things like anti-freeze or abnormal amounts of water.
But realized they could at least check oil viscosity, or you could do that yourself with a viscosity cup available on line for about 7 bucks along with some youtube instruction.

Otherwise, checking the oil for the correct additives that you engine requires & would certainly be a question for the tester.
