Friction is de opposition of motion. if a car is in motion, the friction is said to be reduced because it oppose de movement of the car.
oil
Friction can be reduced by using lubricants like oil or grease on surfaces. To increase friction, surfaces can be roughened or materials with higher coefficients of friction can be used. Adjusting the weight or pressure between the surfaces can also increase friction.
A car increases friction by using brake pads pressing against the rotors to slow down the wheels. The car decreases friction by using lubricants like oil to reduce friction between moving parts within the engine and transmission, allowing them to move more smoothly.

get the best oil you can find
Yes.having low or no oil causes friction in the pistons which will cause car 2overheat.
You can minimize friction in your car (notably in the engine) by always using the lubricating oil and oil level that is recommended by the car manufacturer. Keeping grease points in good condition also helps to reduce friction and wear and tear on moving parts.
Lubrication is the use of oil and grease to increase friction in a vehicle's moving parts
No, it will lubricate the gears. Decrease friction.
The spoiler on a car is meant to create down force on the back or front of a car depending on where it's placed... Which means that yes it does increase friction but it also helps with traction at higher speeds
Friction produces heat. Oil lubricates the engine and reduces friction thus reducing heat.
