Tijuana, Mexico - Desperate times call for desperate measures. As gas prices continue to soar in the US, a growing number of drivers are heading for Mexico to fill up the tanks on their vehicles.

The Mexican government's policy of regulating gas prices to keep their economy going has Americans flocking across the border where the price of gas is around a $1.50 less per gallon. Some analysts are predicting that prices in the US will continue to climb as we head into the summer months.

In San Diego, a gallon of gasoline costs around $4.40, but just a few miles across Mexico's border, in Tijuana, it’s about $2.91 per gallon. It's no small wonder why in cities along the border people are driving into Mexico to fill up their tanks.

But the US State Department warns that these bargain-seekers could be putting their lives at risk. They have issued travel warnings for parts of northern Mexico because of the drug cartels and violence in that region.

"It just goes to show how much Americans want lower gas prices and how far they're willing to go to get them," said Patrick Dehaan, senior petroleum analyst for GasBuddy.com.

But according to Dehaan, while the price may be right, there is no guarantees on the quality of the Mexican gas they're purchasing. "There may be an unknown quality in the gasoline that they're buying in Mexico, and filling up your tank there could actually void a car’s warranty."

But that's not going to stop some drivers who say if prices keep rising, Mexico is one way to help get by. Driving south of the border has been especially beneficial for US truck drivers who buy up to three hundred gallons at once.

"If gas is $5 here, and around like $2 a gallon in Mexico ...I would go down there," states truck driver David Flores.

Although there is no way to track how many US drivers are going to Mexico for cheaper gas, analysts at GasBuddy.com estimate it's in the thousands.
