Sheetz is once again lowering gas prices for drivers over the Thanksgiving holiday, but it’s not a typical grade of gasoline all vehicles use. The restaurant and convenience store chain will offer Unleaded 88 gasoline, otherwise known as E15, at $1.99 a gallon at available locations today through Monday, Nov. 28. Unleaded 88 is considered a biofuel and contains 15% ethanol mixed with 85% gasoline.
While E15 is better for a vehicle’s engine and is more environmentally friendly, the U.S. Environmental Protection Agency has only approved its use for vehicles model years 2001 and newer. Vehicles pre-2001 must use Unleaded 87 or regular gas.
