The national average gas price in the United States has surpassed $4 a gallon, reaching a new record of 158 days above that mark in 2026. According to an analyst, this sustained period of high prices marks a significant milestone. The continuing oil shortage is a primary driver of the escalating costs at the pump across the US. This record exceeds previous durations of high gas prices. The situation is impacting consumers nationwide, with potential economic consequences. Experts predict further price fluctuations are likely as the oil supply remains constrained.
