Your vehicle's fuel economy will almost certainly vary from EPA's fuel economy rating.

Fuel economy is not a fixed number, it varies based on

• Where you drive
• How your drive
• Many other factors

The EPA ratings estimate the MPG a "typical" driver should get under "typical" city and highway conditions. However, most drivers and driving environments aren't typical, and the factors that affect fuel economy can vary significantly:

• Driver Behavior & Driving Conditions
• Vehicle Condition & Maintenance
• Variations in Fuels
• Inherent Variations in Vehicles
• Engine Break-In

So, the EPA rating is a useful tool for comparing vehicles when car buying, but it may not accurately predict the average MPG you will get.
