Anyone know what QT's treatment rate is? Their website says "Some retailers offer higher levels of additives, but only in their premium grades, forcing drivers to pay a premium price for the added benefit. At QuikTrip, we put the same high level of detergent additives in every grade of gasoline we sell." As an example of clarity, Costco states "Kirkland Signature™ Gasoline contains five times the EPA detergent requirement in both regular unleaded and premium grades." I believe the Top Tier minimum is 2.5x the EPA requirement, so I'm just curious what QT's "high level" is exactly.
