What Type of Oil Should Be Used for an Air Compressor Pump?
2 Answers
It depends on the type of air compressor. For small air pumps, general mechanical oil is usually sufficient, as long as the viscosity is not too high. For compressors with a capacity of 0.6 cubic meters or more, specialized compressor oil should be used. High-pressure or high-capacity compressors operating continuously in factories should use lubricants as specified in the manual. Below are some related introductions: Introduction 1: The automotive air compressor works by drawing in natural air and pumping it into the air storage tank or reservoir in the vehicle's chassis. For vehicles with air brakes, insufficient air pressure can affect starting, while for other air-brake vehicles, it can impact braking performance. Introduction 2: When an air compressor fails to build sufficient air pressure, it is often referred to as: insufficient brake air pressure, low brake pressure, the air pump failing to build pressure, the air pump not pumping air, slow air pressure buildup, low air pressure during high-speed driving, normal air pressure during regular driving, or the air pressure not rising, among other terms.
Every time I add oil to my air compressor, I’m extra cautious because using the wrong oil can ruin the machine. When I first started, I used car engine oil, which not only made the machine noisier but also caused carbon buildup that clogged the piston. Later, I switched to synthetic compressor oil. This type of oil typically has a viscosity around ISO VG46, offers good high-temperature resistance, and won’t thin out or leak even when used in the garage during summer. According to the manual, it’s recommended to change the oil every 500 hours of operation, and I always check and top it up on schedule. If the oil level is too low or the oil is too old, bearing wear accelerates, shortening the machine’s lifespan. I prefer branded synthetic oils from reputable manufacturers—they’re more stable and environmentally friendly. Remember to avoid regular engine oil or diesel oil, as their additives aren’t suitable for compression systems. In daily maintenance, cleaning the oil filter and ensuring proper ventilation are also crucial. Choosing the right oil can keep your air compressor running efficiently for at least several years.
