* Year and Model: Different years and trims have different engine sizes and fuel efficiency ratings.
* Engine Type: A smaller engine will generally get better gas mileage than a larger one.
* Driving Habits: Aggressive acceleration and braking, high speeds, and frequent idling will all reduce fuel economy.
* Terrain: Driving in hilly or mountainous areas will reduce fuel economy compared to flat terrain.
* Vehicle Condition: Proper tire inflation and regular maintenance contribute to better fuel efficiency.
Therefore, there's no single answer to how many miles you can get on a full tank. To find a reasonable estimate, you should:
1. Check your owner's manual: This will give you the EPA estimated MPG (miles per gallon) for your specific Trailblazer.
2. Check your fuel tank capacity: The owner's manual will also list the fuel tank size (in gallons).
3. Multiply MPG by tank size: This calculation will give you a *theoretical* maximum range. Keep in mind that real-world driving will likely yield lower mileage.
For example, if your Trailblazer gets 25 MPG and has a 16-gallon tank, the *maximum* range would be 400 miles (25 MPG * 16 gallons). But you should expect to get somewhat less than this in actual driving.
