"Even though oil prices rose last week, prices at the pump slipped lower because of declines in gasoline demand," said Mark Jenkins, spokesman, AAA. "The latest figures from the EIA show weekly demand hitting 4-week lows. Combining this autumn trend with the recent switch to a cheaper-to-produce winter blend gasoline, and prices at the pump could move even lower this fall. However, upward pressure persists due to concerns that there could be major crude supply challenges this fall, due to US-led sanctions against Iranian crude and sharp reductions in economically-stressed Venezuela."
