I recently started using the MudFlap app for purchasing diesel fuel. I paid $4.319/gallon on my last fill up (Saturday in Michigan).
MudFlap set out to pool the buying power of owner operators negotiating discounts with independently owned truck stops and stations with access for commercial vehicles. You don't have to be a trucker to use the app and receive the discount. Savings aren't always this big, but for the last few weeks they've been huge. Rack prices must be falling despite posted pump prices.
Either way. I highly recommend this app.
You pay through MudFlap. Signup is simple. There's a map showing stations and the discounted price.
I got MudFlap from the App Store.
