"While the sun may be fading away briefly today, the sun is certainly not setting on the impressive demand for gasoline we've seen thus far this summer," said Patrick DeHaan, senior petroleum analyst for GasBuddy. "There was nearly insatiable demand for gasoline ahead of Monday's eclipse.  So much so that some motorists in rural eclipse viewing areas may have found filling their tanks more challenging as stations struggle to keep fuel in their underground tanks. But the good news is that the bulk of the motoring public is seeing gas prices drift lower as oil prices have slipped. That trend may continue in the week ahead as oil prices have remained under pressure as the season's close comes into view along with lower gasoline demand and cheaper winter gasoline."
