Goes up and down if there are more particulates of oil
It will be a oil pressure sensor
It's the reminder to change your oil.
it usually turns the light on in the dash to let you know your car does not ave enough oil pressure.
This light represents oil pressure in your engine, it should come on for a short while when you first start it, but should go out quickly, if it does not turn it off and check your oil level.
It runs from the oil pressure gauge to the sending unit on the engine.
This is a pressure sensitive switch that controls the oil pressure indicator (light or gauge) on the dash board in the vehicle
The lighted oil can symbol on a vehicle's instrument panel is intended to warn the vehicle operator that the oil pressure within the engine had dropped below a certain pressure. Also, the light could turn on if the pressure sensing switch, or the related electrical circuits should become defective.

Oil Can? Oil pressure low?
When the engine is running in your car the pressure of the oil activates a switch that is fitted along the oil line. this switch turns of a light that would otherwise be on on the dash of your car whenever the ignition is turned on. If your oil pressure goes down because you are low on oil or because your oil pump is not working properly the light on the dash turn on intermittently or stays on.
The symbol of a wrench and an oil can on the dash of a Chevy Trailblazer means that your vehicle needs oil. If the light doesn't go away oil is added, you need to take your vehicle in for service.
