Finding cheap gas in Ontario (91764)
North Ontario is anchored by Ontario Mills, one of the largest outlet malls in the state, and it sits in the busy wedge between Interstate 10 and Interstate 15. That mall-plus-freeway combination packs a lot of stations into a small area, and competition runs hot.
The stations clustered around Ontario Mills Parkway and the 4th Street area, including a 24-hour ARCO ampm, tend to set aggressive prices because they are fighting for the same shoppers and travelers funneling off two interstates. This is one of the better Inland Empire pockets for finding a low pump price without going out of your way.
Ontario benefits from being inland and freeway-rich, so prices here usually undercut the coastal Los Angeles County markets. If you are passing through on the 10 or 15, the mall-area stations are worth a quick comparison before you commit to a fill. With Ontario International Airport just south of here, the area sees a constant churn of travelers and rental returns, which keeps the nearby pumps competing for that turnover.

How to save more on gas in Ontario
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.
