What kind of oil is used to lubricate door hinges?
2 Answers
Door hinges are lubricated using lubricating oil or grease, both of which provide good lubrication. Before lubrication, the door hinges should be wiped clean. Common engine oil can be applied to the hinge area while rotating the hinge. It is necessary to first remove any rust and dirt from the hinges before applying the lubricant. Door hinges, also known as hinges, are mechanical devices used to connect two solids and allow rotation between them. Due to the different materials of door hinges, their movement states vary. The opening angles of door hinges can be classified into 25 degrees, 30 degrees, 45 degrees, 135 degrees, 165 degrees, and 180 degrees.
I often lubricate the door hinges using grease specifically designed for cars, such as silicone-based or lithium-based grease. They are viscous but don't easily attract dust or moisture, providing long-lasting effects. I usually check every six months, and if the door squeaks or feels stiff when opening or closing, I apply some grease promptly. The process is simple: use a small brush or cloth to apply a small amount of grease to the hinge joints, avoiding excessive application to prevent dirt buildup. Living in a rainy area, lubricating before the rainy season also helps prevent rust and frozen doors. Remember not to use thin oils like motor oil, as they can easily fling off and attract dust; WD-40 can be a temporary fix but offers poor protection. With this habit, my car doors have remained smooth and quiet for five years, reducing noise and wear. I recommend regular maintenance to extend your car's lifespan—don't overlook small details.
