No Oil Reading?
Couldn't find anything on this, so any help is appreciated. I get a mid-service oil change from an independent guy, and they deliberately don't fill it up all the way, giving me the oil to add up to 1 extra liter for fears of overfilling. So as driving home, sure enough, says "engine oil low, add one liter", so after I do this, I don't get get any oil reading at all (it always says 'checking engine oil' but never shows a reading...didn't happen on my 20 mile commute back/forth to work today). Is it possible I added too much oil, still too little oil, or a bum sensor (which seems way too coincidental). Thx in advance.
