Driver FAQs

What is Mudflap?

Mudflap provides instant fuel discounts to thousands of owner-operators and small fleets at hundreds of independent fuel stops and chains like AMBEST, Roady’s, Casey’s, Road Ranger, Sapp Bros and more.

Can Mudflap be used for any diesel-powered vehicle?

Yes, you can save on diesel for any vehicle with Mudflap including pickups and RV’s.

How does Mudflap work?

Mudflap is designed to be simple and easy to use. Here’s how it works:

  • Pick a fuel stop
  • Tap the green button to get a 6-digit fuel code. You’ll need to add a debit or credit card or link your bank account as your payment method
  • Show your code to the fuel desk (they will turn on the pump)
  • Go pump your fuel

Once you’re done fueling, Mudflap will charge you the discounted Mudflap price and immediately email you an IFTA-friendly receipt (no need to pay the fuel stop directly). You can also get a paper receipt at the fuel stop.

When can I make my first purchase?

You can make your first purchase in minutes! If you see a stop on your route, go ahead and get a fuel code.

Does Mudflap charge any fees?

No. There are no fees, no fuel cards, no contracts, no credit checks and no hidden fees.

How do I find stops with instant discounts?

Go to the map in the Find Fuel section of the Mudflap app. You can see all of the discounted prices by either tapping around the map or searching by location or by route.

How does Mudflap provide such great fuel discounts?

Mudflap partners directly with mom & pops and regional chains that want to earn the business of more independent truckers. These stops are willing to offer a special Mudflap-only price that is much better than their pump price or fuel card discounts.

Why do I need to add a payment method to the Mudflap app?

To get instant discounts with Mudflap, drivers buy their fuel using the Mudflap app. Once you add your card or bank account, get a fuel code and pump your gallons, Mudflap will charge your card or bank account for your discounted fuel purchase. You never need to show or give your card to the fuel stop.

Does Mudflap accept fleet cards for payment?

Besides accepting any debit or credit card, the Mudflap app will accept any fleet card that also has a Mastercard / Visa logo on the front and can be used to buy non-fuel purchases like convenience store items.

How secure is the app?

Mudflap protects your payment information with the same bank-grade security and SSL encryption used by Amazon and Google. Your card information is always 100% safe and secure with Mudflap.

I need fuel receipts for IFTA. Does Mudflap provide a receipt?

Yes, for every Mudflap fuel purchase, you’ll automatically be emailed a detailed receipt with a printable PDF-version attached as well. You can also see your entire receipt history in the Fuel Codes section of the app.

Does Mudflap provide an IFTA report?

Yes, you can request a free IFTA report at any time from within the Fuel Codes section of the app.

How many days in advance can I get a fuel code?

Fuel codes are valid for 24 hours before they expire. If your plans change, you can cancel a code at any time with no fee.

If I’m a fleet owner or dispatcher, can I buy for my drivers?

Yes! You can get fuel codes on behalf of your drivers and then just text or email the fuel code to them.

When will Mudflap stops be available everywhere I run?

Soon. We work hard to add new fuel stops to the Mudflap network every day and will soon have you covered across all of the lower 48. If you have favorite stops that you’d like to see added to Mudflap, we’d love to hear your recommendations--please send us a chat, email or call us.

Do you offer discounts on DEF?

Not yet, but we’re working on adding DEF soon!

How does Mudflap make money?

Mudflap gets paid by our fuel stop partners if enough drivers use Mudflap to buy fuel at their location. Mudflap wins when our customers and fuel stop partners win.

How can I contact Mudflap?
