When Should a Car Be Refueled?

[BryceLynn]

Car should be refueled when the fuel gauge indicates one quarter of fuel remaining. Generally, when the fuel light comes on, it means the fuel level has dropped below the fuel pump, and the fuel in the tank is almost exhausted. When the fuel level is too low, the sediment at the bottom of the tank will be drawn into the fuel supply, which can easily cause fuel line blockage or fuel pump obstruction. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The main functions of engine oil are to reduce friction and wear of moving parts, and to remove sludge (one of the functions of dispersants) and varnish (cleaners) from the engine.
