But a 17-mile drive south will save them more than a $2 per gallon. Gas war? Some radio station's wacky promotional stunt? No, Mexican government subsidies that allow filling stations to sell gas for as little as $2.54 a gallon, even less if you have a pocket full of pesos.
Diesel burners have an even greater incentive to make the drive. Diesel prices in San Diego average $5.04. In Tijuana? Only $2.20.
Downside? Of course! Even if you live near enough to the Mexican border, the wait coming back into the States is supposedly terrible, sometimes as long as a two hours. Leave your HUMMER idling that long, and you'll be filling up in Chula Vista.
