This marks the third consecutive increase after one week of decreases, which was preceded by just one week of increases and the highest prices since July 6, 2015, when diesel was $2.832.

The largest average increase was in the Midwest region, where prices at the pump went up by 3.1 cents per gallon. Prices went up five-tenths of a cent in the West Coast less California region, the smallest increase in the nation.
