I have a question about Gas Company's?

Question

The gas stations that have the cheap gas run like water and the ones who are a couple cents higher like Exon are really good gas..

Why?

The only place I will get gas from is Exon because it last long

Answer 1

the good gas is more clean and the cheap gas is really crappy and not clean. not like clean as drinkable but clean as it doesnt go goodin your engine and the good stuff is good for your engine and your engine doesnt burn up as much
