A typical fill for a 2009 Honda Accord requires about 17.1 gallons of gasoline. The total cost to fill depends on your local price per gallon and how full you want the tank to be.
For context, capacity varies slightly by engine and model. The 2.4-liter four-cylinder Accord sedan commonly uses a 17.1-gallon tank, while most V6 configurations run about 18.5 gallons. Always check the fuel-filler door label or the owner's manual for your exact figure.
Fuel tank capacity by engine
Before listing the typical values, note that exact capacity can differ by trim and regional specifications. The following are common figures reported for the 2009 Accord:
- 4-cylinder (2.4L) sedan: about 17.1 gallons
- V6 (3.5L) sedan: about 18.5 gallons
Conclusion: Use your vehicle’s label or manual to confirm the precise capacity for your exact model.
Estimating the cost to fill
To estimate the cost of a fill, you need the current price per gallon for regular gasoline and how much fuel you plan to add. Use this practical approach:
- Find the current price per gallon in your area from sources like AAA, GasBuddy, or the EIA.
- Determine how many gallons you will add. If filling from near empty, use the full tank capacity; if topping up, estimate remaining gallons based on your gauge.
- Multiply gallons by price per gallon to get the approximate cost.
- Remember that pumps may shut off automatically when the tank is full; avoid overfilling.
Real-world factors such as taxes, regional price differences, and station variations can affect the final number.
Illustrative example
Assume a 17.1-gallon tank and a price of $3.50 per gallon. Filling from empty would cost about 59.85 dollars (17.1 × 3.50). If you’re starting with half a tank (about 8.55 gallons remaining), filling to full would cost around 29.93 dollars (8.55 × 3.50) in this scenario. Use the actual price at your local station for a precise figure.
Summary
In brief, most 2009 Honda Accord models require roughly 17.1 gallons to fill from empty, with V6 variants typically closer to 18.5 gallons. The total fill cost depends on the current price of regular gasoline in your area and how much fuel you’re adding. Always verify exact tank capacity for your specific car and use real-time price data to estimate costs.
