Which is more expensive among 92, 95, and 98 octane gasoline?

[LaRonan]

98 octane gasoline is the most expensive. Gasoline is priced according to its octane rating, with 92 octane being the cheapest, 95 octane at a medium price, and 98 octane being the most expensive. Here is some additional information: 1. How to determine the appropriate fuel octane rating for your vehicle: Simply open the fuel tank cap and check the octane rating marked on it. Using the specified octane rating ensures no adverse effects on the vehicle. Failure to use the recommended octane rating may result in engine shaking, increased noise, and reduced power. 2. What to do if 95 octane fuel is not available for a vehicle that requires it: You can opt for 98 octane gasoline or 92 octane gasoline. If choosing 92 octane, be cautious and switch back to 98 or 95 octane when available. Using 98 octane gasoline is safe and won't cause any issues. However, using a lower octane rating than recommended for extended periods can negatively affect the engine.

I've been driving for decades, from old Jeeps to modern SUVs, and I know the prices of 92, 95, and 98 octane gasoline very well. The 98 octane is the most expensive, 95 is mid-range, and 92 is the cheapest, with a difference of a few cents to a dollar per liter. The reason is that higher octane numbers mean higher octane ratings. For example, 98 octane has strong anti-knock properties, making it suitable for high-performance cars to prevent engine knocking. 95 octane is more common and worry-free for daily driving. 92 octane is lower-grade, suitable for older cars, but long-term use may damage the engine. I recommend choosing fuel based on the vehicle manual—don’t be cheap and use the wrong grade, as engine repairs from knocking will cost more. For high-speed driving, use 98 octane for strong acceleration and a thrilling ride, even if it’s more expensive. To save money, look for gas station discounts and avoid peak hours for refueling.

When I first learned to drive, I was curious about the constantly changing prices at gas stations. Among 92, 95, and 98 octane, 98 is the most expensive, 95 is in the middle, and 92 is the cheapest, with a difference of about 30 cents per liter. I mostly use 95 octane because the owner's manual recommends it, saving me the dilemma. 92 octane is tempting in price but I'm afraid of engine knocking; I tried 98 octane once on the highway and it felt powerful, but it made my wallet shrink a lot. Now with soaring fuel prices, I pay more attention to the cost-effectiveness of 95 octane, which is perfectly sufficient for ordinary city commuting. Using 98 octane is a waste of money unless you're driving a turbocharged car. Remember, don't choose fuel randomly; matching it to your car's needs ensures safety and long-term fuel savings.

The price ranking of 92, 95, and 98 gasoline generally places 98 as the most expensive, 95 slightly lower, and 92 as the cheapest. The octane rating affects the anti-knock capability differently. 98 has a high octane rating, making it suitable for high-performance vehicles to reduce the risk of knocking; 95 offers a balance between safety and economy; 92 is the most cost-effective but may not be suitable for modern engines. When choosing fuel, consider the engine's compression ratio and follow the manual's recommendation. Using a lower grade than recommended can cause noise or malfunctions. For everyday use in standard vehicles, 95 is sufficient, and there's no need to pay the premium for 98. Occasionally, considering environmental factors, higher-grade fuel burns slightly more completely, resulting in fewer emissions.
