TN Ag Weights & Measures confirms this station has defective pumps and defective gasoline. The pumps are very slow (20 min to fill 19 gal tank), the auto-stop doesn't work (so gas goes everywhere before you notice), and worst of all, the pumps charge for more gas than you actually bought. I bought 18 gal of gas, but the pump showed I bought 22 gal. How is that possible in a 19 gal tank? At $3.26/gal, this is an overcharge of $12 for one tank of gas. The owner said this is not their problem: it's the cold plus my fault. But TN Ag says cold weather does not slow down a pump. They say that only impure and diluted gas would cause a pump to bog down like this because the impurities are getting frozen. I've been a loyal customer, but no more. I guess this is why they emphasize "100% Gasoline" in their very name.
