A guy I work with that thinks he is smarter than all of us tells me "come check out my new mower"( Home Depot delivered it, started it for him showed him how to use it and they left.) he had been running it all day. When i got there I noticed the oil light was on. He said it had been on ever since he started it. I asked did you check the oil? He replied "no"it didn't have much gas in it so I figured it didn't have any oil either. I read the manual and it said it holds 2.3 liters of oil he said. You guessed it, he poured 2.3 quarts of oil in it. When I pulled the dip stick I could see the oil in the tube.
