I changed the oil yesterday. Would I still need to? Why would I need to?

all the unburnt fuel can wash down the cylinder walls and get in your oil.

over time it will start to cause issues. bearing failure, can wash the oil off the cylinder walls and cause the rings to scuff the walls and possible break rings. lost of compression and potentially chip pistons when/if the rings snap off.
