MPG with different diesel fuel brands

A little bit of interesting data some may like to know.

A little back story..... Due to farm tax expenses and other side businesses I have had over the years, I recorded my full ups for my truck. I have been using an app called aCar for the past five years due to how easy it is and have even started using it for all my vehicles whether I needed it for taxes or not. I usually add notes to each record on what I towed, how much the computer showed, and how much city/highway.

Any-who, being the analytical mind that I am, I decided to pull my records into excel to see if I notice any trends. I immediately noticed one glaring one when I took out my towing full ups and separated winter/summer fuel. Each fuel brand hovered around a certain average mpg with the highest and lowest brand averages being 1 mpg apart.

In my truck Chevron was the highest with an average of 17.2 mpg, followed by Shell with 17.1 mpg, then Buc-cee's at 16.8 mpg, Exxon at 16.5, HEB at 16.4, and Love's & Valero at 16.2 mpg. I pulled the data for my diesel car as well and noticed the same trend with Chevron being higher than the rest by a decent amount. Not only that, but my highest recorded mileage of both diesel vehicles was with Chevron. To be fair, I only fill up at one Chevron station close to my house and cannot speak for other stations or Chevron as a whole.

Anyone else notice different mpg's with each diesel brand?

    Seriously? Why post passive aggressive comments like this?

    I am a former senior purchasing analyst, looking at data and breaking it down is actually stuff I like to do. Not every on is the same and there is probably stuff you do that others think is stupid so don't hate.
  • I'm with you on those brands and the drop off on mileage after Shell is where bio enters the equation.

    I won't discuss off road diesel. :W
  • I have not checked mine. But not a surprise if you do a little googling, you will find some tables posted by different people listing the cetane ratings for different brands. The brands you got your best mpg are the ones with the higher cetane ratings. And the lower mpg are from those with lower cetane ratings such as Loves, Valero, and Flying J.
