What Is The Honda Accord Gas Tank Size?

Knowing the gas tank capacity of your Honda Accord provides key insights into the vehicle’s capabilities. As an experienced Honda mechanic, I’m often asked about Accord fuel tank sizes. The Honda Accord Gas Tank Size ranges from 15.9 gallons in early models to up to 18.5 gallons in recent years. 

With my in-depth knowledge, you’ll have the details to make an informed decision about purchasing or maintaining your Accord. Whether you’re looking to upgrade, estimate fuel ranges, or simply get familiar with your car, I’ve got you covered.

A Look At Gas Tank Sizes Through The Years

As one of the most popular sedans worldwide, the Honda Accord has seen continuous design innovations across its 10 generations. This includes evolutions in the fuel system and Honda Accord Gas Tank Size. Here’s an overview of the tank capacities since the first Accord in 1976:

First Generation (1976-1981)

The original Honda Accord had a modest 15.9 gallon gas tank. This provided decent range as early models focused on fuel efficiency amidst global oil crises. However, limited capacity necessitated more frequent fill ups compared to modern tanks.

Second Generation (1982–1985)

Honda increased the size slightly to 16.1 gallons for the second-gen Accord. A minor upgrade but welcome given new engine options including an available 2.0L.

Third Generation (1986–1989)

No changes were made to the gas tank during this generation. The Accord continued with a 16.1 gallon capacity.

Fourth Generation (1990–1993)

The all-new 4th generation Accord saw the first significant gas tank expansion to 17.2 gallons. This kept pace with competing mid size sedans of the era.

Fifth Generation (1994–1997)

Honda essentially maintained the status quo with a 17.1 gallon tank for the 90s Accord. No major revisions were needed as the range remained competitive.

Sixth Generation (1998–2002)

Once again, Honda made almost no changes with a 17.1 gallon gas tank during this period. Reliability was prioritized over size.

Seventh Generation (2003–2007)

The seventh generation brought a modest increase to 17.9 gallons. This incremental change provided a little more flexibility for long trips or heavy usage.

Eighth Generation (2008-2012)

In the biggest leap yet, Honda expanded capacity to 18.5 gallons for 2008-2012 models. This supported the addition of more powerful V6 engines available during this generation.

Ninth Generation (2013-2017)

Honda dialed back slightly to a 17.2 gallon size for the ninth generation Accord. However, range remained strong with continued improvements in fuel efficiency.

Tenth Generation (2018-2022)

The latest Accords have a 14.8 gallon gas tank. Downsizing was made possible by the model’s economy reaching record highs.
