Just go to stations that are not exxon or mobile these are the big two but the no brand ones could get there gas from these two big companys but just do what you can and this will work I have it going here on the east coast with quite a few people and i tell who ever i meet to do same gas here is any were from 1.65 to 175 for lowest grade so we are a little cheaper but to make this work the work has to get out to a lot of people, these oil company cant eat the gas they have to sell it to us the poeple or consumer.
