What kind of oil is used for lubricating door hinges?

[DiMaximus]

For lubricating door hinges, lubricating oil or grease can be used, as both provide good lubrication effects. Alternatively, a fully synthetic silicone lubricant with strong adhesion, low-temperature resistance, long-lasting performance, and colorless transparency can also be employed. Depending on the number of doors, cars can be categorized into two-door, three-door, four-door, and five-door models. Most sedans for official use have four doors, while family cars may have four, three, or five doors. Sports cars, designed for performance, typically feature two doors. Car doors provide access for drivers and passengers, isolate external disturbances, and to some extent, mitigate side impacts to protect occupants. The quality of car doors is mainly reflected in their anti-collision performance, sealing capability, and ease of opening and closing.
