What does GF5 in motor oil mean?
2 Answers
GF5 in motor oil refers to the specification of the oil. GF5 specification oil can improve fuel economy, effectively reduce emissions, and further protect the environment. Motor oil, also known as engine lubricating oil, is composed of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil's performance. The method for changing car oil is: 1. Lift the vehicle with a jack, locate the drain plug, and unscrew it to drain the oil; 2. After removing the oil filter, place a container underneath it; 3. Replace with a new oil filter and add new oil.
As a car enthusiast, I'm quite fascinated by motor oil specifications. GF-5 is actually the fifth-generation gasoline engine oil standard established by the American Petroleum Institute, meaning it's a quality specification designed for gasoline-powered vehicles. It primarily emphasizes engine and emission system protection while also improving fuel efficiency. When I see this marking while selecting oil, I know the product has been tested to reduce sludge buildup and emission pollution. From personal experience, using GF-5 oil makes the car run smoother, reduces engine noise noticeably, and even saves some fuel. I recommend checking your vehicle's owner's manual to choose oil that meets the standard, while also paying attention to other API classifications like SN or SP as supplements. Regular oil changes are crucial - I check mine every 5,000 kilometers to ensure the oil hasn't turned black or thickened. Neglecting this could lead to engine wear or increased repair costs. In summary, this standard guarantees oil quality, and these small details make a big difference in maintaining your car properly.
