What kind of oil is best for door hinges?
2 Answers
It is recommended to use the specialized HOTO-LUBE door hinge and slide grease from 4S maintenance shops. Here are the relevant details: 1. Do not use Vaseline, engine oil, or vegetable oil for hinge lubrication. These lubricants are liquid-based and only provide temporary relief, becoming ineffective after a few rains. 2. Industrial engine oil emits harmful odors, which are detrimental to health. Ordinary grease has poor low-temperature resistance and may freeze in winter. Additional information: 1. The function of door hinges is similar to that of regular hinges, both used to connect two objects. 2. Common connection methods for door hinges mainly include bolt connection, welded connection, and welded + bolt connection.
I've been driving and maintaining old cars for thirty years, and squeaky door hinges are a common issue. I've tried various lubricants and found white lithium grease to be the most reliable because it sticks well, prevents rust, and doesn't easily fling off. I remember when I didn't know better and used engine oil, but it disappeared within days, leaving the noise unchanged and the door not closing tightly. Later, I switched to specialized grease—just apply a thin layer with a brush, and it seeps into the gaps, providing quiet and wear-resistant performance. I recommend applying it every six months after wiping off dust with a dry cloth, especially before the rainy season, to prevent rust and door deformation. Don't take shortcuts by spraying WD-40—it evaporates quickly and attracts dust, which increases noise. If you use thin oils like cooking oil, it might attract ants and be harder to clean. With regular maintenance, hinge lifespan can exceed ten years, keeping the car smooth and safe.
