if by special, you mean mid grade--- nothing special..Ha!!-- sorry about that, but it was to easy..
do you know that fuel companies do not make a mid grade-per say.. they mix there hi grade with there low grade.. you could do the same by filling halfway with each.. one more -not so known fact.. there are only a few refineries--and a few pipe supply lines, etc.. so what the different fuel companies do is share..
lets say, when an amaco truck pulls into to fill up, it gets the same gas as the shell truck, or citgo, etc.. each company does have its own additives it adds in an effort to personalize the gas the consumer is buying.. but the gas you buy at one station is pretty much the same as the one down the block..
if you thought about it,, it makes alot of sense for the companies--saves them alot of money..
