Climate and Weather: Extreme temperatures can affect fuel efficiency. An engine takes longer to warm up in cold temperatures, and A/C usage increases when it's hot out. Often, this results in higher fuel consumption.
Stable Driving: Some drivers may be tempted to push the Audi A6's performance capabilities with rash acceleration and deceleration. That comes at the expense of fuel economy.
Load and Cargo: Heavy loads or towing will adversely affect the A6's fuel consumption. The more you weigh, the harder your car needs to work to drive you, increasing the amount of fuel it will use.
Car Condition: The more well-kept your car is, the better the fuel efficiency. Worn-out spark plugs, clogged air filters, or old engine oil may also cause lower mileage.
