What does it mean if you check the oil in a lawnmower and its black?
Well my lawnmower won’t start I pull it and then at a point it locks and I can’t pull further and so I have to let go. it has enough gas but I was mowing for a bit and then it made a weird squeaky noise and stopped. I checked the oil and saw it was black. can you guys help me im afraid that I burnt out my lawnmowers engine.

Black oil just needs changing.
Try removing the spark plug if you have a wrench to fit it. Turn the engine over a few times and keep your face away from the plug hole in case the cylinder has somehow become flooded with gasoline. If the engine turns freely, then replace the plug and try to restart it. If not, then you may have a more serious problem.
Also, you didn’t mention if this is a reel-style mower or a conventional vertical-shaft rotary. Most verticals don’t have grease-able bearings in the drive train, but reel-styles do. If there are grease fittings anywhere, there might be a dry bearing, and that would cause a squeak. HyperDog

Its time to change the oil in your lawnmower. When you change the oil the lawnmower will be much happier and will run better. Bones46
