Riverside Gas Tops $6 Per Gallon

Gasoline is back above the pain threshold in Inland Southern California. In Riverside County, the average price for a gallon of regular crossed $6 on Tuesday, May 5, landing at $6.052. That matters on its own, but the bigger story is that Riverside is getting dragged by two forces at once — a global oil shock and California’s unusually fragile fuel system. When both hit together, local drivers feel it fast. ### Why did Riverside jump over $6? The immediate move was simple — the county average rose 2.7 cents in a day and reached its highest level since October 3, 2023. That puts Riverside back in the same expensive zone as other Southern California markets that have also surged this spring. Los Angeles hit $6 in late March, and San Diego moved past $6 in late April. ### Is this just a Riverside problem? Not even close. California’s statewide average for regular reached $6.160 on May 6, while the national average was $4.536. So Riverside is painful, but it is not an outlier inside California — it is part of a broad state spike. The real gap is California versus almost everyone else. ### Why is California so much worse? California gasoline is expensive even before a crisis. The state uses a specialized fuel blend, has higher operating and transportation costs, and carries policy-driven costs on top of taxes and crude. The California Energy Commission’s breakdown shows added costs from programs like the Low Carbon Fuel Standard and cap-and-trade, while California tend to run above the national average. Basically, when crude rises, California starts from a higher base and gets less cushion. ### What’s the global trigger here? Crude oil has been pushed up by fears around supply moving through the Strait of Hormuz — one of the world’s key oil chokepoints. Southern California coverage in late March tied the sharp pump-price jump directly to that Iran-related disruption, and AAA has been telling San Diego drivers that relief depends heavily on those tensions easing. If crude stays elevated, retail gas usually follows. ### Why does California stay volatile longer? Because the state cannot easily swap in replacement fuel from the rest of the U.S. The West Coast is relatively isolated from other refining hubs, and California’s CARBOB gasoline spec limits who can make compatible fuel. EIA has already warned that planned refinery closures — including Phillips 66 in Wilmington cause the lost supply is hard to replace quickly. ### So are drivers likely to get relief soon? Maybe, but not cleanly. If crude cools, prices can ease. But California’s supply setup means pump prices can stay sticky even after the first shock fades. That is the catch — Riverside drivers are not just paying for today’s oil market, they are paying for a fuel market with very little slack. ### How bad is this compared with recent history? Bad, but not record bad. The new Riverside level is the highest since early October 2023. California’s statewide average is still below its June 2022 record of $6.438, but it has moved up fast — from $5.983 a week ago to $6.160 on May 6. That kind of week-over-week jump is why drivers feel blindsided. ### Bottom line Riverside topping $6 is real news, but it is also a symptom. Global oil fears lit the match, and California’s tight, isolated gasoline market keeps feeding the fire. Until one of those breaks — cheaper crude or more dependable supply — drivers should expect the number on the sign to stay jumpy.
