Gas prices have been dropping for the last 18 days straight and the national average price per gallon dropped five cents in the last week.

According to, a provider of retail fuel pricing information and data, the U.S. average is $3.59 per gallon.

This is the first time since April 10, 2014 that prices have gone below $3.60 per gallon.

Prices have dropped for the last 18 days, which is the longest number of consecutive days of decreases since April 4, 2013 and April 19, 2013, according to a relese from GasBuddy.

"West Texas Intermediate crude, the benchmark for the U.S., traded below $100 per barrel today (Tuesday) for the first time since April, reflecting a slow but steady decline in recent weeks," said Patrick DeHaan, Senior Petroleum Analyst for GasBuddy, in the release.

"We're confident that in coming weeks we'll see retail prices catch up to the wholesale losses. West Coast consumers will likely see their retail prices slide from 15 to 25 cents per gallon over the next two weeks, and across the rest of the country we can expect prices at the pump to shed from 10 to 20 cents per gallon," DeHaan said in the release.
