Engine Oil

Engine oil, or motor oil, is a lubricant for internal combustion engines, found in cars and even lawnmowers.  The lubrication increases the efficiency of moving parts which move against each other. Lack of it increases fuel consumption and can lead to engine failure.

Rubbing of engine parts can lead to microscopic metallic parts deposited and circulated in the oil. Therefore an oil filter is often used to clean the oil.

Fog Lights

In fog, you should use fog lights due to limited visibility. They are designed for use in dangerously thick fog. They are completely separate units from regular lights.

Fog light beams are flat and wide, positioned low on the car. Their goal is to cut through fog and light up the road surface so drivers can see the road and stay in lane.

Fog lights are strong - so most places outlaw their use except in severe weather including thick fog. As soon as fog clears or mist dissipates drivers should turn off their fog lights.

Modern vehicles are typically equipped with front and rear fog lights.
