Thousands of engines get their drain bolts over tightened everyday too. Eventually, threads strip. So your gold standard of maintenace is quick lube places? 😂 . Just because your engine didn't blow up doesn't mean its correct practice. What could be the possible benefit of doing that unless consumption is that bad? That's why literally every owners manual says "DO NOT OVERFILL." Remind me not to buy a used car from you.Every car in the fleet runs a quart over.
It’s quite common to run 1/2 to 1 quart over spec. Hundreds of members here have been doing it for years. I’ve yet to hear of even one failure due to a little extra oil. Thousands of engines get overfilled at lube joints everyday. The manufacturer's leave a margin for error for this very reason.
