cheron or cheap gas which would give me bad gas milage

i think it depends on your car and if you're using the correct gas that your car calls for

and how much your foot is on the floor. also a dirty air filter and bad plugs can too

most of the time cheap gas will give you worse milage. Staying out of the gas, starting from a light slower check the air filter and ignition system and all that will add up

will cheap gas faul plugs.well is cheap gas give you bad gas milage and faul plugs on a 2002 taurus i was useing cheap regual gas and started useing cheron regular gas and seemed to getmuchbetter milage be ?
