How to Calculate Fuel Economy (MPG / L/100km)

To measure your actual MPG: fill your tank completely, reset the trip odometer to zero. Drive normally. Fill up again completely. Divide miles driven by gallons used: MPG = miles / gallons.

Example: filled up, drove 312 miles, needed 10.4 gallons to fill up again: 312 / 10.4 = 30 MPG. For L/100km: fill up, drive, fill up again. L/100km = (liters used × 100) / km driven. A vehicle using 6L to drive 100 km gets 6 L/100km.

Factors That Affect Fuel Economy

Speed: Fuel economy peaks at 45–55 mph for most vehicles. Above 60 mph, aerodynamic drag increases rapidly — every 10 mph above 50 reduces MPG by roughly 7–14%. Acceleration: Aggressive acceleration and hard braking waste fuel. Smooth acceleration and anticipatory braking can improve MPG by 10–30%. Tire pressure: Underinflated tires increase rolling resistance. Keeping tires at the recommended PSI can improve MPG by 0.5–3%. A/C: Air conditioning can reduce MPG by 5–25% in hot weather, more on short trips.

Annual Fuel Cost Calculator

To estimate your annual fuel cost: (Miles per year / MPG) × price per gallon = annual cost.

If you drive 15,000 miles/year at 28 MPG with gas at $3.50/gallon: (15,000/28) × $3.50 = $1,875/year. Improving to 35 MPG saves (15,000/28 − 15,000/35) × $3.50 = $135/year. Over 5 years: $675 — enough to evaluate whether a fuel-efficient upgrade pays off.

Frequently Asked Questions

What is a good MPG for a car?

EPA ratings (2024): Economy cars: 30–40 MPG combined. Midsize sedans: 28–35 MPG. SUVs: 22–30 MPG. Trucks: 18–25 MPG. Hybrids: 45–55 MPG. EVs: 100–130 MPGe. The national average for new vehicles is around 28–30 MPG.

Does ethanol fuel (E85) give worse mileage?

Yes. E85 (85% ethanol) contains about 27% less energy per gallon than gasoline. Flex-fuel vehicles running on E85 typically see 15–27% lower MPG. Unless E85 is priced significantly cheaper per gallon, the fuel cost per mile is usually higher.

How much does idling affect fuel economy?

An idling vehicle gets 0 MPG and burns 0.2–0.8 gallons per hour depending on engine size. Modern fuel-injection engines consume less fuel when restarted than during 10+ seconds of idling. Turn off your engine if waiting more than 30–60 seconds.

💡 کیا آپ جانتے ہیں؟

The average fuel economy of new US passenger cars was 12–14 mpg in the early 1970s; today's new vehicle average is approximately 31 mpg.
The EPA introduced standardized fuel economy testing after the 1973 oil crisis, when fuel prices quadrupled and Americans waited in long lines at gas stations.
Electric vehicles convert 77–81% of electrical energy to motion at the wheels; gasoline engines convert only 12–30%, with the rest lost as heat.
