(WTAJ) — Sheetz announced Monday they will be helping drivers save some money at the pump over the Fourth of July holiday by reducing the price of its ethanol blended gasoline for a limited time.

From June 27 to July 4, the restaurant and convenience store chain is charging $3.99 a gallon for Unleaded 88 (E15) and $3.49 a gallon for E85 (Flex Fuel). Sheetz is not dropping the price of Unleaded 87 (regular) which is the most commonly used gas for vehicles in the U.S.

E15 contains a 15% ethanol blend and is approved by the EPA to be used in most vehicles model years 2001 or newer. E85 contains a higher ethanol blend (51%-83%) and is only used in “flexible fuel” designated vehicles.
