What grade of gasoline should the Volkswagen Teramont use?
2 Answers
Volkswagen Teramont should use 95-octane gasoline and must not use 92-octane or lower-grade gasoline. Here are some details about the Teramont: 1. Fuel tank capacity: The Teramont has a fuel tank capacity of approximately 70 liters, ensuring a range of about 700 kilometers. 2. Powertrain: The Volkswagen Teramont is equipped with either a 2.0T engine or a 2.5T engine, each with different gasoline octane requirements. 3. Performance: The octane rating of gasoline represents its anti-knock performance. Using lower-octane gasoline in the Teramont can cause premature combustion, known as knocking or detonation. 4. Risks: Knocking can cause severe impacts on the engine's crankshaft connecting rod mechanism and cylinder walls, and prolonged knocking can damage the engine.
Last time I drove my friend's Touareg on a long trip, I looked into this, and it's actually quite simple: it's clearly stated on the fuel cap. Whether it's the 2.0T or the 2.5T V6 engine, the official requirement for the Touareg is to use gasoline with an octane rating of 95 or higher. Why? These high-performance engines have a high compression ratio, and lower-octane fuel can easily cause knocking, which is like a sudden cramp for the engine and can damage it. I once used 92-octane fuel in an emergency, and not only did the throttle feel heavier, but the engine warning light almost came on. Using lower-octane fuel long-term is even worse—carbon buildup can be 30% higher than normal, and the catalytic converter is more likely to get clogged. If you're on a road trip in the northwest and the gas station only has 92-octane, remember to add a fuel additive immediately after filling up in an emergency. Don't try to save a few cents—it's not worth it.
