ALTOONA, Pa. (WTAJ) — In addition to lowering the price of Diesel gas by 50 cents, restaurant and convenience chain Sheetz is lowering the cost of its Diesel Exhaust Fluid (DEF) to 99 cents until the end of January at various stores.

DEF is used in vehicles with diesel engines with Selective Catalytic Reduction to reduce emissions. Its purpose is to clean up the exhaust gas on a vehicle before it is emitted into the atmosphere.

The average price of DEF at Sheetz stores is $3.50 a gallon. Now, at 99 cents a gallon until January 31, drivers can save between roughly $15 and $75 dollars depending on the size of their DEF tank.

Key Facts About DEF:

It is not a fuel. DEF is used in vehicles with diesel engines with Selective Catalytic Reduction to reduce emissions. Its purpose is to clean up the exhaust gas on a vehicle before it is emitted into the atmosphere.

  • DEF is filled into a separate tank on a vehicle
  • DEF is used in commercial vehicles with diesel engines

Refilling your diesel exhaust fluid is comparable to getting an oil change in your car. If you let it go for too long, it may result in permanent damage to your engine.
