Is 98 More Durable Than 95?

[DelLondon]

98-octane gasoline is not necessarily more durable than 95-octane. A higher octane rating does not mean better gasoline quality, as there is no direct correlation between gasoline octane ratings and fuel quality. Below are the relevant details: 1. The octane rating of gasoline only represents its octane value. Both 95-octane and 98-octane gasoline are high-octane fuels. Compared to 95-octane, 98-octane gasoline has an octane value that is 3 units higher. Increasing the octane value of unleaded gasoline by even one unit requires greater technical difficulty and higher processing costs. Therefore, high-octane gasoline is priced higher than low-octane gasoline. 2. Different engines use gasoline with different octane ratings, primarily determined by the engine's compression ratio. Generally, engines with a compression ratio above 8.0 should use 92-octane gasoline; those above 9.0 should use 95-octane gasoline, and engines with a compression ratio above 10.0 should use 98-octane gasoline.

I'm a truck driver with over 20 years of experience, often hauling cargo over long distances, so I know a thing or two about gasoline. The numbers 98 and 95 refer to the octane rating of the gasoline. 98 has better anti-knock properties, meaning it's less prone to knocking under high temperature and pressure, which can protect the engine, especially turbocharged ones, and in the long run, it might reduce engine wear, making it more 'durable' in terms of maintenance. But when it comes to the fuel's own durability, like how long a tank of gas lasts, I've tried 98 a few times on the highway and it didn't burn much slower than 95. Fuel consumption mainly depends on your driving habits and the condition of your car, not the octane rating. 98 is more expensive, so for regular cars, I recommend just using 95 as per the manual—no need to spend extra unless your car has special requirements.

As an ordinary office worker who commutes by car daily while trying to save expenses, fuel costs are a major concern. I've compared 98 and 95 octane fuels - 98 has higher octane rating and better anti-knock properties, theoretically offering longer engine protection. But for regular family cars like my economy model, 95 octane is perfectly adequate. Using 98 doesn't necessarily make the fuel last longer or improve fuel efficiency. In actual tests, the average fuel consumption per kilometer with 98 octane was similar to 95, with just a few cents difference, but the total cost was higher. The key is to follow the vehicle manual's recommendation and avoid arbitrarily using higher octane fuels. Durability isn't just about fuel lifespan but also engine health - from an economic standpoint, 95 octane offers better cost performance.

As a car enthusiast who often modifies cars, 98-octane gasoline has a higher octane rating and can resist knocking, making it suitable for high-performance engines. 95-octane is sufficient for daily use. In terms of durability, 98-octane is more stable under high loads, protecting the engine and potentially extending its lifespan, but it doesn't mean it's more fuel-efficient or burns slower. Fuel consumption is more determined by driving habits and road conditions, so don't overthink the octane rating—use what's recommended and follow professional advice.

At my age, I've driven quite a few cars and always used 95-octane gasoline. It's reliable and cost-effective, never causing any issues. While 98-octane has better anti-knock properties, regular car engines with lower compression ratios don't really benefit from it—it's just a waste of money. As for fuel durability, all gasolines burn at similar rates; it really depends on how you drive. My advice is not to blindly chase higher-priced gasoline. Traditional experience shows that following the vehicle manual is the safest choice. For most cars, 95-octane is sufficient and more economical—maintaining a car should be practical.

I believe car safety is the top priority, and choosing the right gasoline to prevent engine damage is crucial. 98 octane has higher anti-knock properties, making it more 'durable' in high-performance engines, reducing internal wear and extending engine life. However, its fuel efficiency isn’t necessarily better than 95 octane—it often burns just as fast. For regular cars, mistakenly using 98 octane offers little benefit and is more expensive. Following the manual to avoid knocking issues is the real way to protect your car. Long-term maintenance is the right path—durability depends on overall vehicle care, not just gasoline grade. Don’t mislead yourself by focusing solely on octane ratings.
