Is Walmart Gas Good? Is Walmart Gas TOP TIER?
Walmart does not sell TOP TIER gas. Walmart’s website doesn’t offer any information on its gas quality and corporate customer service representatives could not provide details either. “As far as ingredients go, we don’t have any information on that,” one representative said.
However, TOP TIER provides a list of participating retailers that have agreed to formulate gasoline according to a higher set of standards and Walmart is not on that list. TOP TIER is considered the premier standard for gasoline.

Based on this information, Walmart gasoline may not be the best but it still may be good — there is just too little data available to say.
