Description : Is Arco gasoline inferior to other gasoline brands? If so, then why?
Last Answer : answer:I've never heard about it being bad for cars, but I always tend to get lower gas mileage whenever I use Arco gas. Not huge, but noticeable, and enough that the lower price isn't usually worth it. Mobil ... don't drive my car much at all. I usually ride my bike, so I haven't filled up lately.
