Frequently Asked Questions

Common questions about fuel costs and vehicle expenses

How do I calculate my trip fuel cost?

To calculate your trip fuel cost, you need three pieces of information: your trip distance, your vehicle's MPG (miles per gallon), and the current fuel price. Divide your distance by your MPG to get gallons needed, then multiply by the fuel price. Our Trip Fuel Cost Calculator does this automatically as you type.

What is a good MPG for my vehicle?

A "good" MPG varies by vehicle type. Compact sedans typically get 28-35 MPG, mid-size sedans 25-32 MPG, SUVs 20-28 MPG, and trucks 15-22 MPG. Hybrid vehicles can achieve 40-55 MPG or higher. Your actual MPG depends on driving conditions, vehicle maintenance, and driving habits.

How can I improve my fuel efficiency?

To improve fuel efficiency: maintain proper tire pressure, avoid aggressive acceleration and braking, reduce excess weight in your vehicle, use cruise control on highways, keep your engine well-maintained, avoid excessive idling, and combine multiple errands into one trip. Regular tracking with our MPG Calculator helps identify when efficiency drops.

What is the current IRS mileage reimbursement rate?

For 2025, the IRS standard mileage rate is $0.70 per mile for business use. This rate is updated annually and covers gas, maintenance, insurance, and depreciation. Use our Mileage Reimbursement Calculator to track your business miles and calculate what you're owed.

Does engine idling really waste that much fuel?

Yes! Idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner use. Modern engines use very little fuel to restart, so if you're stopped for more than 10 seconds, it's more efficient to turn off your engine. Use our Idling Cost Calculator to see exactly how much idling costs you.

Why is my MPG lower in winter?

Cold weather reduces fuel efficiency by 10-30% due to several factors: cold engine oil is thicker and creates more resistance, engines take longer to reach optimal operating temperature, winter fuel blends have less energy content, tire pressure drops in cold air, and using heaters and defrosters increases energy consumption. Track seasonal MPG changes with our Gas Mileage Tracker.
