So 30% of the cats were ruined by running a diesel oil in a gas engine? Not good.
You have issue with corellation and causation, plus a basic misunderstanding of generall related facts ("W" rating and oil flow, and engine protection as a simple subset).
The OEM covered them..therefore did not even mount the argument that the oil caused the issue
And you work at a coal burning power plant. Enough of the personal attacks Aussie boy.
Is this an attack on someone based upon where they live and where they work? It sure reads that way. But back to the contention and away from the personal attack.
Biases are real we all have them and like to confirm them, knowing our nature weneed to consider that when attempting to solve a problem. in this case 30% cat failure rate in 100k. A person with a bias thinking oil with phosphorous levels that are high will lead to cat poisoning will see this as confirmation.On the other hand, Let's say the cruisers were a certain make, say GM and I think GM buys crappy cats and this proves my point, it's GM product, my opinion is right!
That's why we always must be open to the fact that correlation is not the same as causation.
By jumping to a conclusion with what we believe to be true and not with what we know to be true we are likely to address a problem improperly and not take actions that resolve the actual cause.
