Moisheh, are you talking about $300 USA per person INTO Mexico? Are you talking about diesel imported into Mexico or USA? If USA, when I was crossing over for the the diesel a couple of years ago USA Customs had instituted a 200 gal limit. Any more and they would take it and there was a limit over a 30 day period. USA Customs was tracking every crossing. My Dodge Ram tankS hold 90 gals so no problem. Also currently as of today diesel is cheaper in Nogales, AZ than Mexico at $3.76/gal. The Speedway @ the corner of Grand & Mariposa in Nogales.
