IN my travels gas buddy finds real savings for example in the Irving< NY area the prices range from $1.66 to $2.31 per gallon that is 65 cents a gallon times 60 gallons in my Motorhome is over $30.00 worth 5 to 10 minute drive
diesel is $1.95 to 2.59 a gallon a similar savings.
It also helps me find Sam's Clubs.
Other times I have found 5-10 cent savings by going a block off the interstate or going to another exit instead of the one I am near. In Ohio the BP at at I90 and Vrootman road is $2.15 a gallon but the next exit east state rte 44 and I90 the BP station is $2.09 a gallon. But the flyingJ at another exit is only $1.95 and I get a discount off that I am going past them all I will pay the cheapest price. 14 cents a gallon savings using a FREE APP. again 60 gallons 7-8 bucks in my pocket with no extra effort on my part
