What lubricant to use for excessive door noise?

You can use a bit of engine oil, but it's best not to use grease as it easily attracts dust and small particles. Introduction to automotive engine oil: Engine oil, also known as engine lubricant (English name: Engine oil), serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Composition of automotive engine oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the performance limitations of the base oil, providing additional characteristics. Additives are an essential part of lubricating oil.
From my car repair experience, door squeaking issues are mostly caused by dry or rusty hinges. Silicone-based spray lubricant works best as it's commonly used on car doors too – just spray it on to silence the squeaks, plus it doesn't attract dust like messy motor oil. The method is simple: first clean the hinges to remove old grime, then spray lubricant evenly and open/close the door several times to let it penetrate. Avoid over-spraying as drips on the floor are hard to clean. This trick works equally well for household doors; just perform annual maintenance to prevent noise and extend component lifespan. If squeaking persists, check if screws need tightening.
