What oil should be used for a squeaky door hinge?

Engine oil should be used for a squeaky door hinge. Here is some relevant information about engine oil: 1. Definition: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91kg×10³ and is hailed as the "blood" of a car. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives can compensate for and improve the shortcomings of the base oil, endowing it with new properties, making them an essential part of lubricating oil. 2. Functions: It can lubricate and reduce friction in the generator, assist in cooling, seal to prevent leaks, prevent rust and corrosion, and provide shock absorption and buffering.

When encountering squeaky door hinges, I prefer to recommend silicone-based lubricants. This type of lubricant remains stable in high-temperature environments and won't attract dust or degrade like regular motor oil. Since car door hinges are exposed to wind and rain, silicone lubricant forms a protective film to reduce friction. I've used it before - just apply a small amount to the hinge pivot after cleaning dust with a soft cloth to avoid mixing contaminants that could worsen the noise. Avoid using WD-40 as it only provides a temporary solution; its thin oil film quickly fails and may corrode metal. Simply inspect every six months - this maintenance also applies to trunk hinges, making the entire door system smoother and more durable. Long-term neglect of hinge noise can lead to wear that compromises sealing and comfort, while simple maintenance significantly extends component lifespan.

As a seasoned car owner, I often handle such issues myself. When the door hinge squeaks, automotive-grade silicone grease is the first choice because its viscosity is just right—a little spray quiets it down, unlike vegetable oil which attracts dust or spoils easily. The process is straightforward: first, use a toothbrush to clean off any accumulated grime, then apply a small amount of grease to the rotating parts with a brush, being careful not to over-apply to prevent dripping. The same silicone grease works well for sunroof tracks or hood hinges. Remember to apply it moderately and do it regularly for smoother operation. If you can't find the specialized grease temporarily, petroleum jelly can be a quick fix, but don't rely on it long-term to avoid accelerating rust and potential failures.

In the automotive repair community, we commonly use lithium-based grease. It is specifically designed for metal friction, offering long-lasting viscosity and low volatility. Applying a small amount to door hinge gaps effectively eliminates squeaks. Just a drop after cleaning is sufficient, avoiding excessive application that could lead to grease buildup. Similar treatment can be applied to seatbelt pivot points to prevent noise as well. It outperforms engine oil significantly, as engine oil has higher fluidity and tends to degrade or evaporate under high temperatures. Regular use extends hinge lifespan and reduces the occurrence of minor issues.
