Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
Oil is used to reduce friction.
Oil it
Yes, Oil forms a coating on the cylinder walls to reduce friction and is also used as a coolant to protect engine parts
How does the flow of air reduce friction of the hovercraft in motion?
Air bearings reduce friction by creating a thin layer of air between the surfaces, allowing them to glide with minimal resistance. This cushion of air helps to reduce friction and improve the efficiency of machinery and equipment.

By lubricating it or adding oil to the surface.
you can use some anti-friction like lubricants (oil,gas).
oil and grease is used in vehicles to reduce friction.
Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
An object can be designed to reduce air friction or drag by improving its aerodynamics, such as streamlining its shape to minimize resistance. Additionally, adding smooth or flatter surfaces can help reduce turbulence and drag. Employing materials with low friction coefficients can also help reduce air resistance.
You can reduce friction by using lubrication, like grease for bearing, sewing machine oil etc.
