Why does the Tayron require 98-octane gasoline?
3 Answers
The Tayron requires 98-octane gasoline because it is equipped with a particulate filter, and using lower-octane fuel may cause clogging and lead to a significant increase in fuel consumption. Below is relevant information about the Tayron: 1. Space: The Tayron measures 4595mm in length, 1860mm in width, 1660mm in height, with a wheelbase of 2731mm. Benefiting from the highly flexible scalability of the MQB platform, the Tayron's space design follows the new golden structure principle, pursuing the maximization of interior space. 2. Handling: The new Tayron is equipped with the EA888 2.0T turbocharged engine and introduces the DQ500 seven-speed wet dual-clutch transmission, surpassing its peers in both power and fuel economy.
Last time I took the Tharu on a long-distance road trip, I specifically tested both 95 and 98 octane fuel. I found that using 98 octane indeed made the 2.0T engine run smoother. The Tharu's turbocharged engine has a high compression ratio, and the higher octane rating of 98 gasoline can effectively prevent knocking. During aggressive driving, the throttle response felt quicker, and the engine noise was significantly reduced. Using high-quality fuel long-term can also reduce carbon deposits, protecting precision components like the high-pressure fuel injectors and three-way catalytic converter. Although it costs a bit more at the pump, the per-kilometer fuel consumption actually decreases when calculated, which greatly helps extend the engine's lifespan. Occasionally using 95 octane is fine short-term, but to truly unleash the Tharu's full potential, 98 octane is the way to go.
I remember accompanying a friend to the 4S dealership for his Tiguan's maintenance, and the technician mentioned this car is quite particular about its 'diet'. The EA888 engine utilizes direct fuel injection technology, resulting in higher combustion chamber temperatures compared to other vehicles. The 98-octane gasoline offers approximately 20% better anti-knock performance than 95-octane, making it more suitable for high-boost conditions. Prolonged use of lower-octane fuel forces the ECU to continuously adjust ignition timing to prevent knocking, which not only reduces power but also increases fuel consumption. A neighbor of mine opted for cheaper 92-octane fuel for half a year and ended up spending over a thousand yuan on carbon deposit cleaning. Nowadays, 98-octane fuel is widely available at gas stations, and making it a habit isn't much of a hassle.
