In general, premium fuel has a higher octane rating than regular fuel. Octane rating measures a fuel’s resistance to knocking, which can occur when the air-fuel mixture in an engine ignites too early. Higher-octane fuels are more resistant to knocking, which can lead to smoother engine operation and potentially improved fuel economy.
Real-World Examples
Several studies have been conducted to assess the impact of using premium fuel on fuel economy and performance. A study by the US Department of Energy found that using premium fuel in a 2017 BMW 330i resulted in a 1.4% improvement in fuel economy.
However, a study by the Automobile Association of America (AAA) found that using premium fuel in a 2016 BMW X3 resulted in no significant difference in fuel economy.
In terms of performance, some drivers report that their BMWs feel more responsive and powerful when using premium fuel. However, there is no scientific evidence to support this claim. In fact, a study by the University of Michigan found that using premium fuel in a BMW M3 resulted in no significant difference in horsepower or torque.
Conclusion
The evidence on the impact of using premium fuel on fuel economy and performance is mixed. Some studies have found a small improvement in fuel economy, while others have found no significant difference. There is no scientific evidence to support the claim that premium fuel improves engine performance.
Cost Considerations
The price of premium fuel is typically higher than that of regular fuel. The exact difference varies depending on the location and time of year, but it can be as much as $0.50 per gallon or more. Over time, this can add up to a significant cost difference.
However, there are also potential long-term cost savings associated with using premium fuel. Premium fuel can help to improve engine performance and efficiency, which can lead to better gas mileage. In some cases, the improved gas mileage can offset the higher cost of premium fuel, resulting in a net savings over time.
Fuel Economy
The fuel economy of a vehicle is measured in miles per gallon (mpg). The higher the mpg, the more miles the vehicle can travel on a gallon of gas. Premium fuel can help to improve fuel economy by up to 5%, depending on the vehicle and driving conditions.
For example, a vehicle that gets 30 mpg on regular fuel might get 31.5 mpg on premium fuel. This may not seem like a significant difference, but over time it can add up to a significant savings. For example, if you drive 15,000 miles per year, the improved fuel economy could save you up to $75 per year on gas.
