What kind of cars usually use 98 octane gasoline?
2 Answers
98 octane gasoline is generally suitable for luxury cars and sports cars with more precise engines and a compression ratio above 10. Here is some information about 98 octane gasoline: 1. Introduction: 98 octane gasoline is also known as "premium gasoline." Compared to other grades of gasoline, it is more expensive but has stronger anti-knock properties, lower sulfur content, higher combustion efficiency, and is less likely to produce carbon deposits and sludge. It provides more powerful performance and makes the engine run more smoothly. 2. Disadvantages of using 98 octane gasoline in regular cars: Occasionally using 98 octane gasoline in regular cars is not a big issue, but long-term use can lead to engine malfunctions and damage.
98-octane gasoline is typically used for high-performance or luxury vehicles, such as BMW M series and Mercedes-Benz AMG models. These cars have higher engine compression ratios and require high-octane fuel to prevent knocking, ensuring smoother and more powerful performance. For regular family cars like the Volkswagen Tiguan or Honda Civic, manufacturers recommend using 92 or 95-octane gasoline, which is sufficient, and there's no need to spend extra on 98-octane. A friend of mine who drives an Audi Q7 always insists on using 98-octane, claiming it improves acceleration, but for ordinary cars, it doesn't offer significant benefits and is just a waste of money. Before refueling, it's best to check the vehicle's user manual, which clearly states the recommended gasoline grade. Don't blindly choose the most expensive option—matching the right grade is key to avoiding increased fuel consumption and potential issues.
