Well it isn't any better evidence than word of mouth but the Infineum fuel report shows differently. From the 2018 report:
East coast Max/Mean/Min
Cetane Number 40 (min) 52 47 43
Cetane Number 40 (min) 60 48 42
Cetane Number 40 (min) 78 53 46
I said as much in my post. About as good as word of mouth. But at least the numbers they did come up with have some scientific backing behind them and there are names to go with it just not known to us. It also isn't an exhaustive sampling of stations either.And the only reasons the West Coast has such a high Max and Mean is due to Propel and Golden Gate Petroleum for the former and CARB Diesel for the latter.
That said however, the report is basically useless without listing brands and actual sources tested with their ratings.
Long range is still an advantage to Diesel power. But my bladder puts a limit on that advantage.
Are these stations company owned or franchises? If the latter, are there different franchisees?This weekend was a little strange. Filled the JSW in Fort Mill, SC on Saturday at a QT for $2.67. Filled the truck in Lake Wylie, SC on Sunday at a different QT for $2.06. Rug at that station was down to $1.92. Driving around Fort Mill on Sunday, I saw diesel prices range about 20 cents but nothing close to what I paid on the other side of the lake.
I don't know the franchaise answers but as far as distance to depot, it would be within a mile, just slightly different routes. Both QTs and both built about the same time.
It always seems that one side of the lake is a few pennies cheaper than the other but 61 cents seems a little excessive.
