Gas Mileage drop

My truck went from getting 11mpg to 7mpg. I don’t know why the truck does not seem to be performing any different and I havn't changed anything. What could cause this? Any help you guys can give me would be appreciated.

If it is running just the same, carefully inspect all the fuel lines for a fuel leak somewhere.

Check your tire pressures, this can have an effect, also have you changed brands of gas?

I do belive I filled up at a diffent station last time but put the same ol 87 oct. in. I'll check the tire pressure tonight we have been having some severe weather changes but I never thought that tire pressure could effect mpg's that much.
