A story with a cautionary note to it

As mentioned, this is more common than you think. We used to get warranty claims from dealers for oil leaks but "upon further review," we found they leaked right after an oil change due to not removing the original filter seal. (I'm a retired engine engineer from one of the "Big 3".)

Fun fact: Something you might be curious about/notice. In general, today's engines are designed such that a leak there at the filter does not spray or drip onto hot parts. You might see little shields, nubs, or a "sugar scoop" sticking out on castings, etc. Anything that can be done to protect the customer in the event of a leak at the filter gasket.
