How Many Types of Gasoline Are Available at Gas Stations?

89, 92, 95, and 98 are common gasoline grades at gas stations, mainly categorized into leaded and unleaded gasoline. The differences between these gasoline grades include varying octane ratings, anti-knock properties, compression ratio compatibility, and suitability for different vehicle types. Octane rating differences: 89 gasoline contains 89% isooctane; 92 gasoline contains 92% isooctane; 95 gasoline contains 95% isooctane; 98 gasoline contains 98% isooctane. Anti-knock properties: The higher the gasoline grade, the higher the isooctane content, resulting in stronger anti-knock performance. Compression ratio differences: Different gasoline grades correspond to varying engine compression ratio requirements. Generally, engines with a compression ratio above 8.0 should use 92 gasoline; those above 9.0 should use 95 gasoline; and those above 10.0 should use 98 gasoline. Vehicle suitability: 92 gasoline is suitable for ordinary cars with lower technical requirements, 95 gasoline suits most vehicles, while 98 gasoline is ideal for luxury cars and sports cars. When refueling, note that lower-grade gasoline can be mixed with higher-grade gasoline, but higher-grade gasoline should not be mixed with lower-grade gasoline. Temporary mixing is acceptable in emergencies but should not be done regularly.

As an experienced driver who frequently maintains cars, I've noticed that gas stations mainly carry several common viscosity grades for engine oil. For instance, 0W-20 is currently the hot choice for new vehicles, offering quick cold starts and fuel efficiency; 5W-30 is also highly popular, suitable for most regular sedans; 10W-40 works well for older cars or high-temperature regions, performing reliably under heavy engine loads. Additionally, there are 10W-30 and 15W-40 grades, designed for light trucks or seasonal adjustments respectively. API ratings like SN or SP differentiate quality levels. Gas stations typically stock 3-6 types, varying by brand and location—Shell stations, for example, may offer a wider selection. Choosing the wrong viscosity can accelerate wear or increase fuel consumption, so it's advisable to consult the vehicle manual or ask staff for the correct match. Regular oil changes are crucial for engine health, as one wrong choice could potentially shorten its lifespan by over 50,000 kilometers.

I've been driving a family car for over a decade, and every time I go to the gas station, I notice several different types of engine oil on the shelves—usually about 4 to 5 varieties. For example, 0W-20 is for high-efficiency models, 5W-30 is what my car typically uses, and 10W-40 is suitable for SUVs or older engines. The choice depends on the car's age and climate: switching viscosity between winter and summer prevents issues. If unsure, I ask the staff or check the packaging instructions. Mid-priced oils offer stable performance, avoiding cheap, low-quality products that can affect engine power. From experience, changing the oil once a year or every 5,000 kilometers helps extend engine maintenance intervals. Once, choosing the wrong type increased my car's fuel consumption by 10%, so now I stick to familiar brands.

How many types of engine oil are available at gas stations? I've refueled several times and commonly see 3-5 models, such as 5W-30 for Hyundai vehicles, 0W-20 for energy-saving types, and 10W-40 suitable for older cars. Choosing oil depends on weather and vehicle model; use low viscosity for smooth starts in cold weather, and high viscosity for heat resistance in hot weather. Using the wrong oil may cause engine noise or slow acceleration. It's recommended to choose fully synthetic oil for better protection. Remember to check regularly and don't delay too long.
