## Description

The Detour Gas Savings Evaluator is a decision-support tool that lets you run quick math on your fuel stops to see if an off-route station actually saves you money. Most people assume a lower price at a gas station means a win, but that's not always true when you factor in the fuel you burn just to get there. This MCP handles the heavy lifting by comparing the price gap against your vehicle's specific fuel economy and the amount of gas you're planning to buy. It's a practical way to make sure a deal doesn't end up costing you more in the long run. You can find it in the Vinkius catalog to connect it to your favorite workspace. Instead of doing mental math or scribbling notes while driving, you can just tell your agent the numbers and get a clear answer on whether to take the detour or stick to the main road. This is especially helpful for long-haul drivers or fleet managers who need to track costs across different vehicles. By automating the calculation of fuel price disparities, you stop making mistakes based on surface-level information. You get to focus on the drive while the agent handles the arithmetic of whether that five-cent difference is actually worth the extra three miles of road. It takes the guesswork out of your fuel strategy and ensures that every stop you make is a smart financial move.

## Tools

### calculate_breakeven_volume
Find the minimum liters or gallons you need to buy to make an off-route stop worth the extra mileage. This tool helps you avoid small tank refills that don't cover the cost of the detour.

### assess_efficiency_sensitivity
See how much your car's fuel economy changes the profitability of a specific gas station detour. It helps you understand how different MPG ratings affect your total savings.

### evaluate_detour_profitability
Determine if a specific detour plan results in a net financial gain or a loss based on your inputs. Use it to get a clear yes or no on whether a cheaper station is worth the drive.

## Prompt Examples

**Prompt:** 
```
Is it worth driving 10km extra for gas? Main route is $1.50, detour is $1.35. My car gets 12 km/L and I need 40 liters.
```

**Response:** 
```
| Metric | Main Route | Detour Station |
| :--- | :--- | :--- |
| Price per Liter | $1.50 | $1.35 |
| Extra Distance | 10 km | - |
| Extra Fuel Cost | - | $0.20 |
| **Net Savings** | - | **$0.30** |

Yes, the detour is worth it. You will save $0.30 after accounting for the extra fuel consumed.
```

**Prompt:** 
```
How much gas do I need to buy at a station 5km away to make it worth it? Main price $1.60, detour $1.45, car gets 10 km/L.
```

**Response:** 
```
To make this detour profitable, you need to purchase at least **2.13 liters** of fuel. 

Anything less than this amount means the fuel burned to get to the station costs more than the discount you receive at the pump.
```

**Prompt:** 
```
What's the minimum km/L my car needs to make a 15km detour profitable? Price $1.40, detour $1.30, buying 50 liters.
```

**Response:** 
```
Your vehicle must achieve at least **15 km/L** for this detour to remain profitable. 

If your car gets less than 15 km/L, the cost of the extra 15km of driving outweighs the $0.10 per liter savings on a 50 liter tank.
```

## Capabilities

### Calculate minimum purchase volume
Find the exact amount of fuel you need to buy to make a specific detour profitable.

### Check detour profitability
Determine if a specific gas station detour results in a net financial gain or a loss.

### Assess fuel economy impacts
See how changes in your vehicle's MPG affect your potential savings on a trip.

### Compare price disparities
Compare different gas price scenarios against the extra mileage costs of reaching them.

### Identify breakeven points
Determine the exact point where extra driving costs outweigh your fuel discounts.

## Use Cases

### The long-haul driver
A trucker wants to know if a station 15 miles off-route at 5 cents cheaper is worth the detour for a full tank. The agent uses `evaluate_detour_profitability` to show the net savings.

### The fleet manager
A manager wants to see if a detour is profitable for a truck getting 6 MPG vs 8 MPG. The agent uses `assess_efficiency_sensitivity` to compare the different vehicle costs.

### The road tripper
A family wants to know if driving 10 miles extra to save $0.20 a gallon matters when buying 20 liters. The agent uses `calculate_breakeven_volume` to find the minimum buy.

### The budget commuter
A driver wants to know the minimum amount of gas they need to buy to make a local detour profitable. The agent uses `calculate_breakeven_volume` to find the break point.

## Benefits

- Stop wasting gas on "deals" that cost more in mileage than they save at the pump. Use `evaluate_detour_profitability` to see the net financial gain or loss of any specific detour before you turn the wheel.
- Know exactly how much fuel you need to buy to justify a detour. Use `calculate_breakeven_volume` to find the minimum purchase requirement so you don't waste time on small tank refills that don't cover the extra miles.
- Understand how your vehicle's MPG impacts your savings. Use `assess_efficiency_sensitivity` to see how much your car's fuel economy changes the profitability of a specific gas station detour.
- Save time on trip planning by letting your agent handle the complex math of fuel price disparities. You can quickly check multiple options without opening a calculator or doing mental math while you are on the road.
- Make data-driven decisions on fuel stops instead of relying on guesswork. By comparing price gaps against mileage, you can ensure that every detour you take is a smart move that actually puts money back in your pocket.

## How It Works

The bottom line is you get a clear yes or no on whether a cheaper gas station is actually worth the drive.

1. Tell your agent the prices at your current station and the off-route station.
2. Provide your vehicle's fuel economy and the total amount of gas you plan to purchase.
3. Get a clear breakdown of whether the detour saves you money or costs you more in fuel.

## Frequently Asked Questions

**Does the Detour Gas Savings Evaluator help me save money on long road trips?**
Yes, it helps you determine if a cheaper gas station is actually worth the extra mileage. It calculates the fuel you'll burn to get there and compares it against the price difference, so you can decide if a detour is a smart financial move.

**How does the Detour Gas Savings Evaluator calculate my fuel costs?**
It takes your vehicle's fuel economy and the distance of the detour to estimate how much gas you'll use. It then compares that cost to the lower price at the destination to give you a net savings figure.

**Does the Detour Gas Savings Evaluator work for different types of vehicles?**
Yes, it works for any vehicle with a known fuel economy. You just provide your miles per gallon or liters per 100km, and it adjusts the math to fit your specific car or truck.

**Can I use the Detour Gas Savings Evaluator to manage a fleet's fuel costs?**
It's perfect for fleet managers who need to verify if drivers are making profitable stops. You can check if a detour is worth it for different vehicle types in your fleet to keep costs down.

**Why should I use the Detour Gas Savings Evaluator instead of just looking at gas prices?**
Because a lower price doesn't always mean a lower total cost. This tool ensures you don't waste fuel on a "deal" that costs more to reach than you save at the pump.

**How accurate is the Detour Gas Savings Evaluator for calculating my savings?**
It provides a precise calculation based on the numbers you provide. By factoring in your exact fuel economy and the distance of the detour, it gives you a much more accurate picture than just looking at a map.

**How does the profitability calculation work?**
The tool calculates the cost of the extra fuel consumed during the round trip detour and compares it against the gross savings gained from the lower price per liter. If the savings exceed the consumption cost, the detour is profitable.

**What inputs are required for `calculate_breakeven_volume`?**
You need to provide the fuel price on your main route, the cheaper price at the detour station, the extra distance added by the detour, and your vehicle's fuel efficiency (km/L).

**Can I use this to plan long road trips?**
Yes, it is ideal for trip planning when you encounter cheaper fuel options off your primary path. It helps ensure that the time and fuel spent detouring actually result in monetary savings.
