Some relief at the pump is on its way for Thanksgiving travelers thanks to Sheetz setting the price of their Unleaded 88 at $1.99 per gallon. Starting this past Monday through November 28th, Sheetz will offer the discounted price per gallon on its Unleaded 88 at 368 of its stations nationwide. Unleaded 88, also known as E15 can be used with passenger vehicles from 2001 and newer and is a blend of 15% Ethanol and 85% Gasoline, which is 5% more than Unleaded 87.
