Premium vs. regular gasoline: no performance gains for most cars

Consumer Reports experts have stated that using premium gasoline in vehicles designed for regular fuel offers no advantages. Their testing revealed no improvements in acceleration, fuel economy, or overall performance.

The study found that in the U.S., the price difference between regular and premium gasoline is about $0.23 per liter. With an average annual mileage of 12,000 miles (approximately 19,300 km), drivers could save up to $351 per year by sticking with standard fuel. For less fuel-efficient vehicles, the savings could reach $526 to $702.

The experts clarify that premium fuel is only necessary for cars where the manufacturer explicitly recommends it. In some models, particularly those with turbocharged engines, it might boost power. However, in most cases, it has no impact on performance. This is because octane rating relates to knock resistance, not energy content, so using more expensive gasoline won't make a car faster.

These findings are especially relevant for owners of used vehicles, where unnecessary fuel expenses can significantly affect operating costs.
