📊 Understanding Your Results

▼

The fuel calculator provides comprehensive transportation cost analysis. Here's how to interpret each result:

💰 Fuel Cost Breakdown

Daily Cost: (Distance ÷ Efficiency) × Fuel Price
Monthly Cost: Daily Cost × Working Days
Annual Cost: Monthly Cost × 12 months
10-Year Cost: Annual Cost × 10 years

Example calculation:
• Distance: 40 km/day
• Efficiency: 15 km/l
• Fuel price: $1.50/liter
• Daily fuel: (40 ÷ 15) × $1.50 = $4.00
• Monthly: $4.00 × 22 days = $88
• Annual: $88 × 12 = $1,056

Key insight: Small efficiency improvements create significant long-term savings

⚠️ Common Mistakes to Avoid

▼
❌ Using manufacturer fuel economy ratings
Real-world efficiency is typically 10-20% lower than EPA/official ratings. Use actual consumption data.
❌ Ignoring driving conditions
City traffic reduces efficiency by 15%. Highway driving improves it by 10%. Factor in your actual commute type.
❌ Not including all driving
Count weekend trips, errands, and non-work driving. Work commute is often only 60-70% of total driving.
❌ Focusing only on fuel costs
Fuel is 25-30% of total vehicle cost. Include insurance, maintenance, depreciation for true comparison.
❌ Comparing different fuel types incorrectly
Diesel has 15% more energy than gasoline. CNG and LPG have different energy densities. Adjust comparisons.
❌ Not considering seasonal variations
Winter fuel consumption increases 10-25% due to cold weather, heating, and winter fuel blends.
❌ Overlooking maintenance impact
Dirty air filter, low tire pressure, and poor maintenance can reduce efficiency by 10-25%.
❌ Ignoring alternative transportation
For short commutes (<20 km), public transit or cycling might be cheaper and healthier.

🚀 Pro Tips for Fuel Efficiency

▼
💡 The 80 km/h Sweet Spot
Most vehicles achieve peak efficiency at 80-90 km/h. Every 10 km/h above 100 km/h reduces efficiency by 10-15%.
💡 Tire Pressure Optimization
Check monthly. Under-inflated tires (20 psi low) reduce efficiency by 10%. Over-inflate by 2-3 psi for maximum efficiency.
💡 Weight Reduction Strategy
Remove 50 kg of unnecessary weight to improve efficiency by 1-2%. Clean out trunk, remove roof racks when not needed.
💡 Fuel App Optimization
Use GasBuddy, Waze, or local apps to find cheapest fuel. 10¢/liter savings = $100+ annually for average driver.
💡 Eco-Driving Techniques
Accelerate gradually, anticipate traffic, use cruise control on highways. Can improve efficiency by 15-20%.
💡 Route Optimization
Combine errands into one trip. Plan routes to avoid traffic. Use navigation apps for real-time efficiency routing.
💡 Maintenance Schedule
Follow manufacturer schedule religiously. Clean air filter, quality oil, proper alignment can improve efficiency by 10%.
💡 Fuel Quality Matters
Top-tier gasoline (Shell, Chevron, Exxon) has better detergents. Can improve long-term efficiency by 2-4%.
