Burning gasoline in a car's engine a physical change or a chemical change?
Chemical but the energy released has physical consequences.
Is the burning of fuel in a car a chemical or physical change?
It would be a chemical change because it is burning. Like a newspaper on fire.
Is burning gasoline in a lawnmower a physical or a chemical change?
Any burning is a chemical change. When gasoline (mostly a hydrocarbon called octane) burns, or combusts, it reacts with oxygen in the air to produce water vapor, carbon dioxide, and a bunch of heat energy, which your lawn mower engine harnesses to do work (turn the blade.)
What type of change occurs when a car engine consumes gasoline - chemical or physical?
I don't think burning a gas to power a car is either Chemical nor Physical. If you burn gasoline to power a car, it is therefore a chemical AND physical change because both the chemicals and the look changes. However, a car being powered has nothing to do with the substance of gas being changed. If the car uses the gas to power itself, it'll turn the gas into gas again, so I'm not sure how this works. In conclusion, it's probably neither.

Is carbon dioxide being produced by the combustion of gasoline in an automobile engine a physical or chemical change?
When the gasoline burns, it forms water and various gasses, so it is a chemical change.

it is a chemical change because it causing the fuel to burn
Is a car driving over a puddle a chemical or physical reaction?
When a car drives through a puddle of water, the change that takes place in the puddle is a physical change. Of course, chemical changes will take place in the engine of the car, but that's probably not what you are asking.
