When we were in Mexico in March avgas was in the $3.50 a gallon range. I don't think Mexico imports any gas. I see they have now jumped on the rip off band wagon.

Mexico just informed us that the price for Avgas has just been increased.
In following up and checking with several AOEs, we find the following:
MMSF: US$6.20 per gallon
MMCN: US$5.92 per gallon
MMLT: US$5.19 per gallon
The above does not reflect any taxes
