Can Engine Oil Be Used as Lubricating Oil?
2 Answers
Engine oil is a type of lubricating oil, which is a professional term encompassing various categories and grades, such as gasoline engine lubricating oil, diesel engine lubricating oil, and transmission lubricating oil. Below is a detailed introduction about it: Introduction One: Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction, maintain mechanical equipment, and protect processed parts. It primarily serves functions such as lubrication, cooling, rust prevention, cleaning, sealing, and cushioning. Introduction Two: Different categories of engine oil cannot be used interchangeably, as doing so may adversely affect the engine. For example, gasoline engine oil cannot be used in diesel engines.
Having driven cars for many years, I know engine oil is the engine's exclusive treasure—designed for high temperatures and speeds, with high viscosity and cleaning additives. If used on door locks or bicycle chains, it attracts dust, thickens, and hardens, potentially jamming the equipment and causing malfunctions. I once saw a friend use it to lubricate garden cart wheels, only for the bearings to rust and fail. Specialized lubricants like WD-40 are lighter, rust-resistant, and better suited for various scenarios. Don’t cut corners by substituting engine oil, as it may shorten equipment lifespan and waste time and money. Always prioritize the right lubricant for the job—matching the application ensures efficiency.
