GF-5 oil means that the oil is SN grade, which is the highest grade of oil, and has passed GF-5 certification. The following is relevant information: 1. API: API (American Petroleum Institute) adopts the oil quality rating standard, which divides lubricants into two categories: gasoline engine (S) and diesel engine (C). Gasoline engine lubricants are represented by S, followed by an English letter (such as SE, SF, SH, SJ, SL, SM). The further back the letter is in the alphabet, the higher the quality of the lubricant. Currently, the highest-grade SN is considered the top-grade oil. 2. Viscosity-temperature characteristics: Engine oil formulated with low-viscosity base oil and viscosity index improvers, which has good viscosity-temperature characteristics and can meet the requirements of both low and high-temperature use, is called thickened oil or commonly referred to as multi-grade oil. The index used to evaluate the viscosity-temperature characteristics of engine oil is the viscosity index.

I need to talk to you about the GF-5 motor oil standard, which is an important specification for gasoline engine oils, introduced by the International Lubricant Specification and Approval Committee (ILSAC) around 2010. This standard primarily aims to improve fuel economy and protect modern engine designs. For example, it mandates the use of low-viscosity oils like 0W-20 grades, which reduce internal engine friction and save approximately 3%-5% on fuel. Additionally, it enhances cleaning performance to prevent carbon buildup and emission issues, while also being compatible with turbocharging technology. I often use this oil because it’s more reliable than the older GF-4 version and has a longer service life. When selecting motor oil, just look for the ILSAC Starburst symbol on the packaging. Overall, using GF-5 standard oil saves money and offers peace of mind, especially for vehicles manufactured after 2010, helping to avoid frequent repairs.

As someone who has driven various cars, let me talk about the benefits of GF-5 oil. It's one of the latest gasoline engine oil standards, focusing on fuel efficiency and engine protection. It undergoes rigorous testing to ensure low wear and smoother engine operation. I prefer choosing this oil during oil changes because it extends engine life and reduces the frequency of oil changes, while its low viscosity makes starting the engine easier. Don't overlook the GF-5 label on the oil packaging when purchasing, as oils without it may not be compatible with modern systems. Simply put, this standard makes driving more economical and eco-friendly, saving a significant amount on fuel costs in the long run.

I have 10 years of driving experience and have changed oil many times. The GF-5 standard was actually introduced to replace the older GF-4, with a greater focus on fuel efficiency and protection. It specifies that the oil should resist high-temperature oxidation to reduce maintenance frequency. I used it in my old car and found the engine noise was significantly reduced. Just make sure to check the label when choosing oil to avoid counterfeit products.
