What does PAO fully synthetic engine oil mean?
2 Answers
PAO engine oil is a type of olefin-based engine oil, belonging to synthetic base oil. The following is an introduction to the advantages and applicable scope of PAO engine oil: Advantages of PAO engine oil: PAO engine oil has excellent high and low-temperature performance, a wide working temperature range, high flash and fire points, ensuring safe use. It features low evaporation rate, minimal coking, long service life, high viscosity index, excellent viscosity-temperature performance, outstanding anti-emulsification and anti-foaming properties, good electrical performance, thermal stability, and chemical stability. It is also non-toxic and non-irritating. Applicable scope of PAO engine oil: PAO engine oil is suitable for formulating high and low-temperature aviation lubricants, high and low-temperature grease base oils, internal combustion engine oils for cold and extremely cold regions, gear oils, hydraulic oils, refrigeration oils, automatic transmission fluids, high-viscosity aviation lubricants, oils for CNC machine tools, air compressor oils, long-life lubricants, transformer oils, insulating oils, high-voltage switch oils, metalworking fluids, thermal oils, etc.
I often do car maintenance myself. PAO full synthetic oil refers to the type of base oil that uses polyalphaolefin as its core, representing the top-tier formulation of fully synthetic oils. Unlike conventional oils, PAO is entirely artificially synthesized, free from mineral oil impurities, and boasts exceptional high-temperature resistance. This means the oil doesn't thin out easily during high-speed driving or aggressive driving, while it flows quickly at low temperatures to protect components and reduce wear. After trying it, I found that engine starts are smoother, and the oil change interval can be extended from 5,000 to 10,000 kilometers. It's especially suitable for older cars or SUVs like mine, making maintenance much more hassle-free and even saving a bit on fuel costs. However, it's a bit more expensive. If you're on a tight budget, you might consider trying semi-synthetic oil as a transitional option, depending on your car's condition.
