Finding cheap gas in Riverside (92504)
This is Arlington, the historic Riverside neighborhood on the western end of the city, built around Magnolia Avenue, the grand tree-lined boulevard originally designed as a carriage way. Settled in 1875, the area has seen real revitalization, and Magnolia still serves as its commercial backbone.
Magnolia Avenue and the surrounding arterials carry most of Arlington's stations, with the 91 Freeway forming the neighborhood's southern edge. The everyday neighborhood demand keeps these corridors competitively priced rather than chasing freeway through-traffic premiums.
Riverside County fuel comes in below the coastal metros, and Arlington's mix of long-established commercial strips gives drivers genuine choice. Comparing a few stations along Magnolia before filling is the easy way to find the better price in this corner of the city. Because Magnolia runs for miles through Riverside, it is worth checking a couple of stations a half mile apart rather than settling for the first one you reach.

How to save more on gas in Riverside
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in California
California has the highest gas taxes in the nation at roughly 60 cents per gallon when you combine the state excise tax with the cap-and-trade program and underground storage fee. The state requires a special CARB-formulated fuel that only a handful of in-state refineries can produce, so a single refinery outage can spike prices statewide within 48 hours. Costco, Sam's Club, and Arco are typically the cheapest across Los Angeles, San Francisco, San Diego, and Sacramento metros, while Chevron, Shell, and 76 dominate freeway exits. Stations along Interstate 5 and US 101 commonly run 10 to 20 cents higher than equivalent stations a mile off the freeway.
