The cheapest diesel on your route. Net. True cost, not the posted price.
The price on the sign doesn't tell you what it actually costs you. Your true cost is the pump price, minus the fuel tax (IFTA) you recover, minus your cardlock rebate. Between two stations on the same corridor, the true-cost gap runs 15 to 30¢ a gallon — calculated across 2,800+ real stations. SentinelleFuel ranks every stop on your route by true net cost and tells your driver exactly where to stop. No detour.

The posted price lies.
Your true cost is elsewhere.
We calculate it.
The cheapest station on the sign isn't always the cheapest for you. Your true net cost = pump price − the fuel tax (IFTA) you recover by state − your negotiated cardlock rebate. Once those two numbers are counted, the ranking changes. Here's the same 375-gallon fill, seen at the posted price and at true net cost.
- Fill 375 gal
- Posted pump price $4.05 US/gal
- IFTA tax + rebate counted no
- True net cost $4.05 US/gal
- Fill 375 gal
- Posted pump price $4.20 US/gal
- − IFTA tax recovered + cardlock rebate − $0.35/gal
- True net cost $3.85 US/gal
Covered on the first optimized fill. $50 CA per truck / month.

If your trucks run
the US,
you're paying too much at every fill-up.
Not because your drivers do a bad job. Because nobody calculates the true net cost between two stations on the same corridor — IFTA tax and rebate counted. That gap exists on every route, every day. It's the easiest cost to fix.

Does SentinelleFuel cover the routes I run?
Yes — coverage includes Canada (cardlocks and BVD) and the US (I-95, I-40, I-10, I-75 corridors and most inland routes). If your route falls outside this zone, write to us before subscribing: admin@groupesentinelle.ca.
How do you calculate "true cost"?
For each station: pump price, minus the fuel tax (IFTA) you recover by jurisdiction, minus your negotiated cardlock rebate. That true net cost is what ranks the stops — not the price on the sign.
Will my drivers actually use this?
The driver app is mobile, no account to create. One screen: next stop, litres, true cost. Most use it on their first trip, no training.
What if the pump price is different when I arrive?
Prices are updated daily from station sources. An occasional gap is possible — a safety margin is built into every recommendation. Across a full route, net savings stay positive.
What exactly is the free audit?
You send me the CSV from your fuel card. I replay every fill against the cheapest station by true cost that was on your route that day. You get the exact amount left on the table. No commitment, confidential data.
Stop paying
