Noticed a trail of oil drips followed me into work... friggin filter cap o-ring bulged out after torquing it to (as it's printed right on it) 25nm. Fixed it in the parking lot after serendipitously finding a 36mm combo wrench in a random tool chest. Lost about 1/2 liter after driving about 20mi yesterday oblivious to the problem post-oil change and failed to notice generous parking spot oilage this morning on departure.
