Bottlenecks at oil refineries have sent gas prices surging.

Sheetz, a chain of convenience stores, is cutting gas prices for the busy July 4 weekend. 
The discount only applies to certain types of fuel: unleaded 88 and E85. 
 The national average gas price was $4.88 on Tuesday, according to AAA. 

Sheetz is looking to relieve some pain at the pump through a July 4 promotion. 

Amid record-high gas costs, the chain has cut prices for certain fuel types through the holiday weekend, it said on Monday. It’s now selling unleaded 88 for $3.99 per gallon and E85, a fuel with extra ethanol, for $3.49. 

Unleaded 88 can be used in cars, trucks, and SUVs from the 2001 model year or newer, the Environmental Protection Agency says. E85 only works with so-called flexible-fuel vehicles, so it’s best to consult your owner’s manual before filling up. 

The deal ends on the evening of July 5, a Sheetz spokesperson told Insider. 

The national average price for a gallon of gasoline was $4.88 as of Tuesday, according to AAA. Earlier this month, gas prices hit a peak above $5 per gallon, the highest price AAA has ever recorded. Russia’s invasion of Ukraine — and subsequent sanctions against Russia — has shocked the global oil supply, keeping upward pressure on gas prices since March. 

Sheetz operates some 640 stores across Pennsylvania, West Virginia, Virginia, Maryland, Ohio, and North Carolina. The discounted fuel types aren’t available at every location. Customers can find locations that offer E85 and unleaded 88 on Sheetz’s website
