Many US drivers, including owners of luxury and performance cars, are choosing regular gasoline over premium fuel due to high prices. Sales of premium gasoline dropped by 5% in late June 2026, as rising fuel costs linked to the US-Iran conflict pushed consumers to seek cheaper options.
Fuel Price Trends and Consumer Behavior
After a recent spike in fuel prices, the average cost for a gallon of gas began falling below $4.00 in early July, according to AAA Fuel Prices. However, the high prices in June led many drivers to change their fueling habits.
- Premium gasoline sales dropped 5% between June 22 and June 25 compared to February’s average, based on data from the Upside cash-back app.
- Mid-grade gasoline sales also fell by 2% in the same period.
- Regular gasoline sales rose by 10%, as many drivers sought to cut costs.
Why Drivers Are Skipping Premium Gas
Many upscale vehicles require premium gas (91 octane or above) for optimal performance or engine safety. Yet, the jump in prices encouraged some owners to risk using regular gas despite potential downsides.
- Using lower octane fuel in cars requiring premium can cause engine knocking and possible long-term damage.
- Some manufacturers only recommend premium for peak performance, not strict necessity.
- Brands like Mazda highlight performance gains with premium fuel, but vehicles may still run on regular gas at reduced outputs.
Performance Differences Within Model Lines
Luxury models sometimes share engines with mainstream versions, with software adjusting power based on fuel quality. For example:
- Nissan Armada: 425 hp and 516 lb-ft torque
- Infiniti QX80: 450 hp and 516 lb-ft torque
- Toyota Grand Highlander Hybrid Max: 362 hp and 400 lb-ft torque
- Lexus RX 500h F Sport Performance: 366 hp and 406 lb-ft torque
These differences show how fuel type can impact performance, but also offer choices for owners feeling the pressure of fuel costs.
Why It Matters
With fuel prices still unsettled, drivers are finding practical ways to reduce expenses. Using regular gasoline instead of premium can save money, but owners should weigh the risks against potential engine damage or performance loss. This trend highlights the ongoing impact of geopolitical events on everyday driving choices.
