There’s been a tremendous surge in RVing over the past couple of years but we’ve also seen a surge in gas and diesel fuel prices lately, so we thought this might be a great time to do a post on some great apps to find cheap gas.

For the purpose of this article, we’ll use the term “gas” because most of the apps use that term exclusively. But we’re really talking about fuel here – both gasoline and diesel – for the benefit of owners of all types of vehicles.

And, yes, we know that there are many “Fuel Discount” programs out there you can join. But many of those programs are very limiting, often limiting you to diesel fuel and truckstops… which, in our experience, have the HIGHEST fuel prices in any area. You’re paying a premium for the convenience they offer along major interstate routes.

There are other aspects of being forced to use the truck lanes at fuel stops that we object to (often slick with diesel fuel, potentially interfering with truckers who are working, etc), but those details are a topic for another day. Today we’re talking about price.

Saving money on an inflated price sort of defeats the purpose (and eliminates the savings)… and we’ve found that we can usually save at least as much, and often more, by using the apps listed below to find the cheapest gas on our route.

5 Apps to Help You Fill Your Tank on a Budget

We’ve selected five apps to focus on here, and we’ll share with you their websites, any fees and discount programs that apply, and the best features of each.

We’re pretty sure one or all of these will save you a few bucks when you fill up, and if you’re filling a tank the size of ours, you’ll see some significant savings at the pump.

So, let’s get to it!

#1. GasBuddy

GasBuddy is an app & website to find cheap gas and can also save you money in numerous additional ways.

About GasBuddy

GasBuddy is a pretty amazing app, not only in our opinion but also according to many reviewers who’ve used the app for a long stretch of time. It’s the primary tool that we use to find the cheapest prices on fuel wherever we go.

Sure, GasBuddy is an app to find cheap gas and as such will show you the stations near you with the cheapest fuel, but that’s not where this money-saving app stops.

You can get a free Pay with GasBuddy card which you can link to your checking account and then use as a debit card to pay for your fuel. 95% of fueling stations accept the Pay with Gasbuddy card, so you’ll have the convenience of using the card to pay for your gasoline and/or diesel purchases pretty much anywhere (some small local retailers may not participate, but 95% gives you pretty good odds), but that’s not all the card does.

In addition to convenience, the Pay with GasBuddy card saves you up to an additional 25 cents per gallon automatically.

So, you’ll use your GasBuddy app to find the cheapest gas near you, you’ll fill up at that location and use your Pay with GasBuddy card to pay for your fuel, and you’ll get additional savings deals just by using the card.

There are also station-specific promotions and seasonal promotions which can add even more to your savings over time.

While the Pay with GasBuddy card is free (sign up on the website or the app, no credit card or credit check necessary), GasBuddy also offers exclusive benefits with their Plus and Premium accounts that, for additional monthly fees, offer extra savings above the free plan.

NOTES ABOUT THE “PAY WITH GASBUDDY” PROGRAM:

    • The Pay with GasBuddy program is available only within the United States to US residents (you must have a US mailing address). Registration requires providing your US drivers license for identity verification, and you will need a US-based bank account to link to for payments.
    • The Pay with GasBuddy program has $75/day and $300/week limits. Once you’ve reached either of those limits, your transaction will stop. So, if you need more fuel, you’ll need to start a second transaction with another payment method.

GasBuddy App Cost

The GasBuddy app to find cheap gas is FREE for both iOS and Android users. And, for most users, that’s all you’ll need to start saving.

GasBuddy Coverage

Fuel price data is available for locations throughout the US and Canada.

Best Features of the GasBuddy App to Find Cheap Gas

The best features of GasBuddy include the ability to show you which fueling stations around you have the cheapest gas prices on the day you need to fuel up. And because the app is map-based, it’s easy to scan around along your route to see what fuel prices are like where you’re heading to. It lists prices of all grades and types of fuel, and the time of the last price update at that location.

GasBuddy allows you additional ways to save money using their free Pay with GasBuddy card as well as the ability to earn free gas back in the away of points accumulated… and there are numerous opportunities to save money not only on fuel but also at some of your favorite retailers.

GasBuddy’s website offers a trip cost calculator so that you can see what a projected trip will cost you in fuel, and you’ll find features such as gas price charts and maps, an outage tracker, and even vehicle recall notices.

GasBuddy is a feature-rich app to find cheap gas prices and much more. That’s why it’s our absolute #1 go-to way to locate fuel, especially when we often take on 120 gallons or more of diesel fuel in one fill. Knowing our fuel range, we can use GasBuddy to look far along our route to see where the best place is to stop.

And if you’re wondering if we can fit our 43′ rig + Honda toad into any gas station, that’s where Google Maps & StreetView come in. When we spot the cheapest fuel on our route, we can simply scope the station out in advance to get an idea if it’s tiny or huge, and what the layout is like.

About Google Maps

We might not think of Google Maps as an app to find cheap gas, but in fact, it is! Once in your Google Maps app, you simply use the search feature and search either “gas” or “gas station”, and you’ll see nearby fueling stations displayed on the map with the gas prices at each station. You can even search using a specific brand of gas.

Alternatively (and even easier), is the “Gas” button in Google Maps. Simply open Google Maps on your phone, then beneath the “Search Here” box just scroll the list of quick searches until you see “Gas,” click it, and all of the nearby gas stations will be displayed along with current gas prices at each.

Pinch & zoom your phone screen to see more or fewer options with the ability to compare nearby prices.

Open the app, hit the “Gas” button, and there you have displayed before you all nearby gas stations and the current price of gas at each. Simple, quick, effective. Just what we want when we’re on the road. And since you’re probably already using Google Maps to navigate, being able to search for gas along your route is extra handy, too.

About Waze

Waze is a subsidiary of Google and is actually a navigation app, like Google Maps. It works on any smartphone or tablet with GPS support. Waze can function as an app to find cheap gas, but also offers turn-by-turn directions as well as additional trip information such as travel times and route details such as traffic alerts, police notices, and hazards ahead on your route.

Within Waze, you can find the cheapest gas along your travel route by tapping on “Gas Stations.” From there you’ll be shown a map with gas stations indicated as well as a list of nearby gas stations, how far away they are, and what the current cost of gas is at each location.

You can find parking using the Waze app, and you can even listen to your favorite music or podcasts right from within Waze.

NOTE: Waze directions are not intended for oversized vehicles or emergency vehicles. If you’re driving a very large motorhome, this may be a consideration in the sense that routing may not take the size of your rig into consideration.

Best Features of the Waze App to Find Cheap Gas

Waze utilizes data submitted by its users to constantly update its traffic information, making it easier to avoid snarl-ups caused by construction or accidents. If you tend to travel in metropolitan areas, Waze can be a lifesaver!

Are These Gas Apps Accurate?

For the most part, the answer to this question is yes. There are a number of apps to find cheap gas out there that are rarely updated and are thus frustrating to use. We’ve chosen five apps to share with you that are as accurate as gas apps can be.

In some cases, you’ll actually be able to see when the gas price displayed was last updated. You may notice, as we have, that they’re generally updated daily or at least within the past few days. And many of the apps will stop displaying a fuel price if the last posted update was too long ago.

Can You Still Save Money if You Have a Big Gas Tank?

Heck, yes! You can save even MORE money if you have a big gas tank!

Let’s say you’re using one of these apps to find cheap gas and you pop it open and find that a half-mile away there’s a station with gas that’s ten cents cheaper than most in the immediate area. If you fill your 50-gallon tank, you just saved yourself five bucks. If you fill your 100-gallon tank, you just saved yourself ten bucks.

Doing this throughout your travels your gas savings really add up! And if you use a program like Pay with Gasbuddy, you can save a whole lot more.

So, yes – you can save money using an app to find cheap gas, no matter the size of your rig OR gas tank!

Conclusion

We hope this round-up of five free apps to find cheap gas is helpful to you in a variety of ways since they all offer lots of good information and travel assistance.

No matter which free app you choose, saving money on gas, especially with prices rising as they have this summer, always makes sense!
