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.

if you sign up use the referral code: br3a29

Some of today's prices with MudFlap.

the cheapest diesel here is Walmart at 5.69. Mudflap has a station at 4.68. It's a little out of the way but if I need 20 gal, that's $20.

I wish I'd had know about this sooner. I could have saved a pile of money over the last few years.

Mudflap is real. Still a little sparse here out west, but the discounts are almost as much as I get with my trucking association membership.

It's almost non-existent in OR. We get over to Winchester Bay once in a while. Once you leave Idaho, the only station anywhere near that route is in Eugene and it's PUC only. I'm not a trucker and don't have their PUC card. We also get to the Tacoma area on occasion. There are some good prices in that direction.

Is there a way to make it work without sending a picture of your id? Not sure if it even works up here.

I didn't have to send a picture of my ID. I just signed up and added a Credit Card for payment.

I just checked and there are no stations listed in Alaska.

Thanks

Walmart must have read my post. Today they dropped it from 5.69 to 4.99. Still .30 higher than the Mudflap station, though.

It asked me for my ID as well... and I'm not comfortable giving that out to a fuel app. It already has my name, phone number and email address.

I use Dino App. You sign up attach a card, 10 cents /Gal discount. If you get the Sinclair card ,another 10 cents. I think mud flap is good ,depending where you are.

Are there many participating stations in the Louisville Or Cincy areas?

iOS or ???

I did not have to provide my ID to proceed. Can you skip that step?

IOS won't ask for your ID but you'll have to text them a photo of it before they'll set up your account.

We have 1 Mudflap station here. Their price today is 3.64. That's $1.85 lower than the average here. Walmart is the cheapest at 4.99.
I just bought 10.5 gal, about $38. They billed my card $250, than an hour later they credited back $212. I don't know their reasoning for that.

This is the same process anytime you use your CC to pay for fuel at the pump. Your card is preauthorized for their maximum per cycle transaction(this amount varies usually by station). You don't normally see it, because you're not looking for it.

You should have gotten $10 in free fuel added to your account if you used the referral code: br3a29

I checked my fleet discount on Monday, and the participating trucks too (travelers oasis) was at $3.63. $3.52 today. That’s $2 (a little over, actually) off the posted retail price.

Normally the spread is not nearly that large, but prices are “sticky” on the way down.

Does show Mudflap is legitimate and competitive with a commercial fleet consortium price.

It finally allowed me to bypass it, but will not give me codes without both sides of my ID and a selfie. I've talked to half a dozen of the twits that work there and they refuse to provide their privacy policy or let me talk to anyone with half a brain. I've talked/texted with a few cants that knew nothing except circle logic... no matter how much sense and reasonable arguments I made, they only became more bitter and emboldened in ineptitude. My privacy is worth more than $1 a gallon. They have told me for over a month now that a supervisor would contact me, but every time I call in it's the same old bitter cants.

Well that sucks.

I don't remember having to give them a pic of my drivers license. I did submit a credit card for payment. I might have given them the DL, I was exhausted when I signed up. I really don't remember that being a requirement. Maybe they changed their policy. Are you using IOS or Android? I could see someone using stolen CC#s. Maybe they had problem.

So for your troubles.

Reading reviews, one said it only works on the high flow pumps. True?

That depends on the station. The one here works only on the truck island. I like the truck islands better anyway as it saves time pumping.

UPDATE:
I haven't been driving the pickup much this winter so I haven't needed much diesel. I've only filled it twice since learning about Mudflap and neither time was it below half. So far, I've saved $27 in only 2 fill ups. I'm comparing the Mudflap prices to Walmart, the cheapest diesel in town. I drive by there a couple times a week. We only have 1 station nearby who's on Mudflap and it's 13 or 14 miles to it from home and it's well out of my usual line of driving. This station isn't the cheapest one around by any means.

Is there a way to find out if I have any stations in my local before I give them my credit card?

Or if someone can look, I am in Colorado Springs


Thanks in advance.

You can download and install the app without entering your CC until you use it. Right now I see 2 stations in Co. springs, both priced at 4.58. One is the Maverik at I-25 exit 138. The other is a Maverik on E. Filmore. There are a number of others in surrounding towns.

OK thanks,When I tried to install it today, it asked for my credit card.I will have to re look it. I know where both those stations are.

I really appreciate you looking it for me.

We do t have enough stations to worry about that. There is one though where I’d only buy fuel in an emergency - Big John’s in Sterling. $0.40 more thana station half mile away.

I’ve been using it for just a couple of months. Usually around 20 cents off pump price. Last week have a station where it was 50 cents off pump price. Paid 3.50 per gallon, still too high. Ha ha

I added the app, I live in AZ, not many here and they are about 3 hours away. Those prices are about .30 lower, great deal if I ever get close to em.

The last few weeks, the nearest one to me is .20 higher than a couple other local stations. Previously, it was quite a bit lower. I can't explain how prices are set.

What I see is that our wholesale prices drop much faster than retail prices. Discounts are the steepest when prices drop fast. When prices have been stable for a long time, discounts tend to be small.

That's often because a retailer has tanks full of fuel that they paid a high price for. They try to not sell it at a loss.

It seems over the last several months there was not that much savings with Mudflap app. However yesterday I filled up in MO at 2.99 per gal with the app. 0.70 or so off pump price. Thank you whoever is helping me out.
