Local gasoline prices have fallen for the sixth consecutive week, sagging to their lowest point in 2 1/2 months, a new report shows.

And the descent — rare for May and June — is expected to continue.

GasBuddy, a price-tracking website, said Monday that the average price of gasoline in Lancaster County tumbled another 6.5 cents over the last week, dipping to $2.78 a gallon.

“Last week saw a feat most motorists probably thought they'd never see in June — average gasoline prices declined in nearly every state across the country,” said Patrick DeHaan, head of petroleum analysis for GasBuddy.

DeHaan attributed the decline in prices at the pump to “a deep drop in oil prices (due to) worries that tariffs could slow economic growth, reducing oil demand.”

The analyst said it’s likely that motorists will get “more good news at the pump than bad for the foreseeable future” due to growing inventories of gasoline.

Local gasoline prices have been both unusually low and unusually high so far in 2019.

The year began with prices dropping to an 18-month low in early January to $2.38 a gallon.

Prices then began a steady ascent, reaching $3.04 a gallon — a 12-month high — in late April.

Then came the six straight weeks of decline, which shaved a total of 26 cents off the average price here, according to data from GasBuddy’s survey of 147 stations here.
