Why does the Volkswagen Talagon require 98-octane gasoline?
2 Answers
To meet emission requirements by addressing particulate filter issues. Below is relevant information about oil grades: 1. Definition: Oil grades consist of two parts - classification and viscosity specification. Oil grades typically indicate viscosity and quality, with lubricant viscosity often marked using SAE grade standards; 2. Viscosity indication: On oil packaging, you can see SAE and API markings, where SAE stands for the Society of Automotive Engineers and API represents the American Petroleum Institute. The number following SAE indicates the oil's viscosity value, while the marking after API shows the oil's quality grade; 3. Classification: Automotive oils are specifically categorized into 4 types for summer use, 6 types for winter use, and 16 all-season types. Summer oil grades are: 20, 30, 40, 50 - with higher numbers indicating greater viscosity; Winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W - where smaller numbers before W indicate lower low-temperature viscosity and better low-temperature fluidity.
Our family drives a Volkswagen Talagon, and why does it specifically require 98-octane gasoline? Primarily because its engine is designed with exceptional precision and a high compression ratio, much like a high-performance heart that demands premium fuel. Using regular gasoline can easily lead to knocking, which means the gasoline ignites prematurely in the cylinders, causing pinging sounds and power loss. Over time, this can also damage engine components. From my actual driving experience, using 98-octane fuel results in smoother starts and more powerful acceleration, especially noticeable when climbing hills. While filling up with 92 or 95-octane might be cheaper, the manual clearly states that 98-octane is required; otherwise, performance isn't guaranteed, and issues may arise. Additionally, I've compared it to neighbors' SUVs like the Highlander, which can run on 92-octane, but the Talagon's turbocharging system is more aggressive, necessitating higher-octane fuel to maintain stability. In short, for the longevity of the car and a more enjoyable driving experience, spending a bit more on fuel is worth it.
