How many miles can a 2003 Pontiac Montana get on full tank of gas?

The fuel efficiency of a 2003 Pontiac Montana depends on several factors including engine size (there were a few options), driving style, road conditions, and vehicle maintenance. There's no single answer.

To get an estimate, you'll need to know the specific engine size (e.g., 3.4L, 3.1L) of the minivan. Once you have that, you can look up EPA estimated MPG (miles per gallon) for that specific year and engine. Then, you'll need to find out the fuel tank capacity (usually around 20-25 gallons, but it's best to check the owner's manual).

To calculate the potential range:

1. Find the EPA MPG: Search online for "2003 Pontiac Montana [engine size] MPG."

2. Find the fuel tank capacity: Check the owner's manual or the fuel filler door.

3. Calculate the range: Multiply the EPA MPG by the fuel tank capacity.

This will give you a *theoretical* maximum range. In reality, you'll likely get slightly less due to varying driving conditions.
