How the Math Works
Fuel consumed
Distance × (Consumption ÷ 100)
Total liters burned on the trip.
1,000 km × (9.5 ÷ 100) = 95 L
Fuel cost per grade
Fuel consumed × Price per liter
What you pay at the pump for this grade.
95 L × 54 ₽/L = 5,130 ₽
Catalyst wear cost
IF Sulfur > 50ppm THEN (Distance ÷ 1000) × Degradation rate × Catalyst cost ELSE 0
High-sulfur fuel accelerates catalyst degradation. Below 50ppm = negligible wear.
Example (92, sulfur=10ppm): Sulfur ≤ 50ppm → wear cost = 0 ₽
Total trip cost
Fuel cost + Wear cost
The real number to compare across grades.
5,130 ₽ + 0 ₽ = 5,130 ₽
Sources & Defaults
- SAE 2003-01-0934 — catalyst aging study (default 0.8% degradation per 1000km)
- Aftermarket parts survey 2024 — typical catalyst replacement ₽80,000–250,000
Every variable above is editable in the calculator — change degradation rate to 0.4% for newer cars, 1.2% for older.
