PEORIA, Ill. (WMBD) — Gas prices have declined for the eighth straight week as the average gas price in the city fell 24.7 cents this week to an average of $4.21 per gallon Monday.

Per GasBuddy’s predictions, the national average is poised to fall under $4 per gallon as early as Monday, and 100,000 gas stations across the state will be under $4 per gallon by the end of the week.
“Diesel continues to decline as well, and will likely soon fall under $5 per gallon,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The groundwork is laid for a ninth week of decline, with areas of the West Coast soon ditching the $5 per gallon average. While I’m upbeat the drop can continue for another couple weeks, we’re starting to see some activity in the tropics, which may increase risk of potential disruption.”
The price of diesel has declined 13.1 cents nationally in the past week and stands at an average of $5.14 per gallon.
