Can You Safely Use Gas from Different Stations?

You don’t need to stick to one gas station for refueling. It’s perfectly fine to fill up at different locations as needed.

Most gas stations source their fuel from the same major suppliers. The gasoline isn’t altered or modified by the station itself.

While it’s okay to vary your gas stations, it’s wise to primarily use one you trust. Many drivers choose a station they pass regularly, like on their daily commute.

How Switching Gas Stations Can Benefit Your Car

Surprisingly, using different gas stations might improve your vehicle’s performance. Each fuel brand uses a unique blend of additives, and higher-quality additives can enhance fuel performance.

Sticking to one brand may lead to residue buildup in your fuel system. By occasionally switching brands, you introduce varied additives that can help clean out deposits and prevent new ones from forming.

Regular vs. Premium Gasoline Options

Most gas stations offer both regular and premium gasoline, regardless of the brand.

Many drivers assume premium gas is always better, often paying significantly more per gallon. However, premium fuel isn’t always the best choice for every vehicle.

For smaller cars, premium gas is often unnecessary and could even harm the engine. It doesn’t improve performance or clean fuel lines. Unless your car’s manual specifies premium fuel, regular gasoline is sufficient.

Older vehicles, however, may require premium gas due to their need for higher-octane fuel to operate smoothly.

Select a Gas Station with Knowledgeable Staff

Some gas station employees may not inform you about the potential downsides of premium gas. They’re unlikely to discourage you from buying it, as it’s more profitable.

Gas stations prioritize profit, and since selling premium fuel is legal, they won’t always guide you toward the best choice for your car.

You can ask about the octane ratings of their fuel. Premium gas typically has a higher rating, often 9 or 10, while regular gas is slightly lower.

Be cautious not to use premium gas in a vehicle that doesn’t require it, and avoid using regular gas in cars that need premium. Always consult your owner’s manual if you’re unsure.

Verify the Gas Brand Before Filling Up

Gas stations may sell different fuel blends during summer due to regulations. Some gasoline brands have higher volatility levels, which can affect your car’s performance.

In colder months, fuel volatility isn’t a major concern. However, in summer heat, high-volatility gas can vaporize too quickly, reducing efficiency.

Regulations prohibit gas stations from selling fuel with volatility levels above 9.0 in summer, and some areas enforce even stricter limits, like 7 or 8, to protect vehicles.

Why High-Volatility Fuel Poses Risks

High-volatility fuel can be problematic. In hot weather, it may evaporate before reaching your engine, forcing you to refuel more often.

Additionally, it can lead to vapor lock, which may cause stalling or even damage your engine or fuel pump over time.

To avoid these issues, always check the fuel type during summer months to ensure it meets your vehicle’s needs.

How Many Gasoline Types Exist?

According to ExxonMobil, there are over 14 gasoline varieties available today. Some are designed for high-performance cars with elevated octane levels.

Others are formulated for standard vehicles like cars, trucks, and SUVs, typically costing less than premium options. Generally, reputable brands of regular gas are reliable, as long as they’re not the cheapest available.

Final Thoughts

Ultimately, the gas station you choose isn’t critical, but avoid low-quality, cheap fuel. Bargain brands often use inferior additives that could harm your engine.

Stick to well-known brands like ExxonMobil, Sunoco, or Wawa for better reliability. Use common sense when selecting fuel, and your car should perform well.

By making informed choices about gasoline, you can keep your vehicle running smoothly without unnecessary expense.
