Culver City Observer -

As gasoline prices across the US continue to rise, Americans are looking for cheaper ways to fill their tanks - and some are even seeking deals in another country.

In the US state of California, which consistently ranks among the highest in the nation for gasoline prices, some are heading across the US-Mexico border in search of savings.

Even before Russia's invasion of Ukraine in late February, the cost of gas in the US was ticking upwards. According to the US Department of Labor, gasoline prices rose 40% from January 2021 to January 2022.

Russia is the world's third-biggest oil producer and the conflict sent gasoline prices soaring in the US and elsewhere. Earlier this month, the average cost of a retail gallon of gasoline hit $4.33 (£3.31) - reaching 14-year highs - according to the American Automobile Association (AAA).

The average price of gasoline in California is currently $5.91 per gallon and $4.24 per gallon nationally, AAA data says.

It's a different story in Mexico, where earlier this month President Andres Manuel Lopez Obrador promised to control gasoline prices by subsidising fuel.

On TikTok, Julio Vaquero, a resident of San Diego, just 17 miles (23km) from the border, posted a video showing how he filled up his Honda Civic in Tijuana for $40.

"Eight hundred pesos, filled it up. Full tank," he said, showing the gasoline station's pump display and his car's full fuel gauge.

The short TikTok has over 1,900 likes.

He told the BBC that one week later it cost him $70 to fill up in California.

Mr Vaquero lives about 20 minutes from Tijuana and tends to visit every other month, but he said if prices keep going the way they are, he's going to start making weekly trips to Mexico for cheaper gasoline.

When he calculated the gallon price, he said $3.75 per gallon at a Chevron in Mexico was a steal compared to nearly $6 per gallon in San Diego.

The price at Pemex, a state-owned Mexican company, he noted, was even cheaper at $3.30 per gallon.

Another southern California resident, Ken Barnes, told the BBC that while he and his wife don't currently make specific trips to Mexico for gas, they do "purposefully avoid filling up in the US before leaving".

Mr Barnes lives about 20 miles from the border, but he said that if he has plans to go to Mexico, he is sure to "cross the border, then fill up".

The couple is also relying on their electric vehicle more, he said.

Despite the high prices, demand for gas has still risen nationally, according to GasBuddy, which provides real-time gasoline price updates, It rose 2.9% in mid-March, though why demand has risen is unclear.

For people looking for a deal, Patrick De Haan, head of gasolineeum analysis for GasBuddy, said driving further for lower-priced gasoline can pay off - but it all depends how much cheaper it is and how far you need to go to find the savings.

"Generally, small cars must save one cent per gallon for each mile they drive out of their way, while SUVs need to save at least two cents per gallon for each mile they drive out of their way," he said. "Smaller vehicles get better miles per gallon so it means they spend less driving out of the way."

Mr De Haan also cautioned about the time investment of crossing the border twice, saying it might not be "worthwhile unless you have a massive tank, such as an RV". GasBuddy recommends limiting fuel consumption and driving in a way that maximises fuel efficiency instead.
