Every Nigerian driver has had that moment: you just filled your tank for 30k, and by Friday, your gauge is already crying. So, you start wondering, “Is it my car, my driving, or just the fuel?”

That’s exactly why the Fuel Calculator exists. It tells you, in plain numbers, whether your car is sipping or gulping fuel. And the best part? It adds a bit of gist and humor while at it.

1. Choose What You’re Checking (L/100km or MPG)

Before you start, pick the measurement you care about.

• L/100km: This tells you how many liters your car burns to move 100km. Lower is better.
• MPG (Miles Per Gallon): This one flips it, showing how many miles you go per gallon. Higher is better.

Hit the button for the one you want. The active mode turns blue so you know what’s up.

2. Type in Your Car’s Number

Enter your fuel consumption value into the box. No complicated math, just the number.

The calculator does the heavy lifting instantly, giving you the converted figure right below. No “submit” button, no waiting. You type, it calculates.

3. Read Your Result Like a Pro

Once you type, the app flashes your exact result in a clean blue card.
If you’re converting L/100km, you’ll see the equivalent MPG. If you’re converting MPG, you’ll get the matching L/100km value.

It’s fast, accurate, and clean enough to screenshot if you’re trying to brag.

4. Check Your “Efficiency Rating” (This Part Is Fun)

Below your result, you’ll get a quick vibe check on how fuel-efficient your car really is:

• Excellent (Green): You’re saving money and saving the planet. Superhero behavior.
• Good (Blue): You’re doing fine. Your wallet is happy.
• Average (Yellow): You’re in the middle zone. Decent, but could be better.
• Poor (Red): My guy, that motor is drinking fuel like it’s juice. Check it.

Each result even comes with a random witty line to make you smile (or feel called out).

5. Switch and Compare (If You Want to Show Off)

Curious how your friend’s “fuel economy” really compares? Switch modes, enter their numbers, and check side by side. You might just win that argument about whose car is the real fuel guzzler.
