"Ok, I have owned diesel vehicles for 20 years, and reading these posts has confused me! I have never used gasbuddy on any other app. Driving on Interstate's you will see signs about services provided at the next exit, gas stations with diesel are listed, if it does not specifically state diesel, then do not exit there"
From my perspective its not so much where diesel is available but rather the price. For example in B.C.(Canada) i can pay 4.73 per US gallon whereas if I go to Wash state(20 miles or so) the price is 3.75(Cdn). I can hold 110 gallons so Gas Buddy is my friend. SAving almost $100 isn't chicken feed.
