The Jetta, a popular compact car, typically requires refueling every 300 to 500 miles, depending on driving conditions and fuel efficiency. This range is based on the average fuel economy of most Jetta models, which hover around 30 to 40 miles per gallon (mpg) for highway driving.

The frequency of refueling for a Jetta is influenced by several factors. First, the car's fuel efficiency plays a significant role. Modern Jetta models are designed to be fuel-efficient, with some models achieving up to 40 mpg on the highway. However, driving habits, such as aggressive acceleration or frequent stops, can reduce fuel economy and necessitate more frequent refueling. Additionally, the quality of the fuel can impact fuel efficiency. Using premium fuel when not necessary can decrease fuel economy and increase the frequency of refueling.

Data from the U.S. Environmental Protection Agency (EPA) provides insights into the average fuel economy of Jetta models. For instance, the 2020 Volkswagen Jetta has an estimated fuel economy of 33 mpg on the highway and 42 mpg in the city. This translates to approximately 375 miles per tank, assuming a full tank capacity of 14.5 gallons. However, this number can vary based on driving conditions and individual driving habits.

In conclusion, the Jetta generally requires refueling every 300 to 500 miles, with fuel efficiency being the primary determinant. By maintaining good driving habits and choosing the appropriate fuel grade, drivers can optimize their refueling frequency and reduce overall fuel costs.
