I can think of two reasons why a drain plug on the bottom of the engine is needed. 1) Complete and fast dump at the bottom, to drag out sediment, and 2) a magnetic drain plug is more effective on the bottom where teeny metal flakes settle. I was really pissed when I discovered that the Briggs and Stratton 6.5hp engine on a Craftsman self-propelled walk behind mower I bought had no drain plug at all. Not on the bottom, not on the side. You turn the lawn mower over to drain it. It is in the owner's manual

Unfortunately, the gas cap is made to wheeze to prevent vapor lock so you have gasoline dripping if you don't run it out of gas or drain the thing before you "drop" the oil. Really?
