Southern California drivers head to Mexico for cheaper gas

SAN DIEGO - Some motorists in southern California are willing to drive south to find lower gas prices.

A steady line of cars crossing from Tijuana to the United States.

Many tourists bringing back everything from bowls to blankets but there's one other thing they're bringing these days: a full tank of gas.

One motorist said, "Some people just come here to Tijuana now to just fill up with gas and go back to San Diego."

The price difference between the U.S. and Mexico is dramatic.

California drivers are paying nearly $4 a gallon for regular gas, in Tijuana it's $2.75.

One motorist said. "Because I always load full in California and it's like 35 dollars. And right here in T-J, it's like 30 dollars, so five dollars difference."

The difference is dramatic with Pemex gas stations everywhere selling regular gas more than a dollar lower than the U.S.

The diesel difference is even more.

The average in California: $4.71.

In Mexico, truckers are filling up for $2.10 a gallon.

Young Jesus Hernandez sells drinks and chips to American drivers filling up their tanks.

A motorist says "well, it's $100 to fill this up in Point Loma, where I live, and it's about 70 bucks to fill it up here."

Now you may be able to buy your gas much cheaper.

But then, there's the issue of crossing the border.

A motorist says "if you come late at night, when there's no line at Delinea where you might only have to wait 20 minutes, then it's worth it."

But even locals admit when it comes to sitting in traffic for two hours the trip may not be worth your time.

A motorist says "no, because it's too much line."

Still with prices like this it's a temptation to enter Mexico on empty and return with a full tank.
