Finding Diesel

Hi folks.

We purchased our first diesel truck in February. A 2014 Sierra 3500 HD. I've been reading a lot about diesel trucks as it pertains to pulling a trailer, but what I haven't found is info on types of diesel, if there are types, like grades of gas. We take our first longer trip to Boise, ID from Walla Walla, WA in a couple of days. About 4 hr trip. Towing a lighter TT about 30ft. I'm assuming I'll make it there with diesel to spare. But if I were to pull into a Flying J or similar type of truck stop, do I get my diesel from the gas pumps where cars go, or can I get it from where the big rigs get their's? Dumb question I know.

I usually map out my gas stops when we take off for a longer trip. We used a Suburban before we bought the truck. I'd look at gas stations on google to make sure I'd pull in and out with relative ease. I'm about to do the same, but finding I can't assume all gas stations have diesel--a couple in my town don't.

Is there an app for the iPhone I'm not aware of that lists gas stations with diesel? Is there another way I'm not thinking about yet?

Finally, not a diesel question, but does a longer bed truck make a HUGE difference in the towing experience? We have a long bed with crew cab!

Thanks!
  • Besides straight ULSD, there is bio diesel of various %, such as 5,10,20% etc.Be aware of what % of bio diesel your truck is made for.
    In addition, in colder areas of the country, some diesel has non gelling additives certain times of the year.
  • I too use Gas Buddy App and filter diesel stations. I think I have only filled up my diesel once outside of my home area (fuel range is 700+ highway miles) and found a station that clearly advertised diesel price from the interstate. You should be aware there is "off Road" Diesel as well as various % of biodiesel blends. You should consult your owners manual for the highest % of biodiesel blend your truck is designed for. Both should be clearly marked on the pumps.

    There is just one grade of Diesel that you can legally use in your truck: Ultra low sulfur diesel and that is what you will find at any gas station. And you can get it at the islands for semi's; the pumps are much faster and you fill up the tank more quickly. Just do not leave the truck sitting at the pump while you go into the store to use the rest room ect.

    The Gasbuddy app you can get on your cell phone will find diesel stations for you.

    Not correct or complete info..... You can also use Bio Diesel, which can be as much as 20% depending on location and fuel distributor. Some vehicle manufacturers restrict the percentage of bio, so you must know what your vehicle can use.

    Also, if you want to use the truck islands, make sure your truck has the larger fill hole at the fueling point, as NOT all trucks are so equipped.
  • I have the gas buddy app. Never really used it traveling. Thanks! I see the stations with diesel, so now I can check them on google.
  • If you have a cell phone there are 2 Apps I would recommend you have--GasBuddy and iExit--both are free and I consider a definite must when traveling. Lars
