COSTCO vrs SAMS CLUB Gasoline - Is There a Difference?

That isn’t in evidence. And even if it were, you’d want to know whether that means there would be some noticeable effect at 10,000 miles vs. 200,000 miles, or at 1,000,000 miles vs. 20,000,000 miles. You’d also want to know the cost to repair and the cost of only buying top-tier gas vs. buying by price. You might also want to know the cost and effectiveness of other alternatives, like putting a bottle of fuel injector cleaner in the tank every now and then.

That sounds like a lotta work, I’ll leave it others to figure that one out. Besides that, the nearest Sam’s Club to me is three times the distance to two Costco’s. I think I’ll just keep going to Costco to fuel our ICE car, it’s only once a month or so.
