I am not disputing your claim on how much they use, it would be nice to see independent confirmation of that. I hear a lot "double the amount" and now your 5X the amount, anecdotally, but no report from anywhere that confirms it. Please provide if you have a link to one. I would actually prefer additives injected into fuel stream as it is loaded on the tanker. The mix would be consistent and uniform. I have tanked fuel in the past, and seen the process as it is streamed into the tanker.
I have no bias about Costco fuel. I am not going to drive 45 miles to the nearest Costco to buy it, even if it is indeed the "best". I am not sold on Costco TT to the point of using several gallons of gas just to go get it.
I have started using a TT gas recently, since my local Farmer's Coop went Cenex and now is TT. I have never asked them about it. I just like getting 4-5 cents a gallon off by having the Coop's fuel card.
