Annual fuel figures are the EPA snapshot at the source date. The calculator below uses the separately dated fuel-price record and your inputs, so the estimates may differ.
2018 Honda Civic annual fuel cost calculator
Start with the combined MPG for 1.5L 4-cylinder turbo, Manual 6-spd, Front-Wheel Drive. Replace it with your measured gas mileage and local pump price for a personal budget.
Formula annual miles ÷ MPG × gasoline price
Fuel cost per mile equals gasoline price divided by MPG. Multiply by your annual mileage for a yearly fuel budget. Add maintenance to estimate cost per mile. For a specific journey, budget a road trip and settle passenger shares.
Budget a transmission service for your confirmed procedure
Calculate drain-and-fill fluid purchases, parts and labor using the refill quantity and cycle count confirmed for your exact transmission. A listed total capacity does not establish the service refill amount.
