What speed is best for gas mileage?

The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).

Why are K&N filters bad?

The rate of airflow affects engine performance, and the K&N filter abandons the paper setting and uses a more porous entry point, an oil-based foam material. But this has the obvious disadvantage of allowing some dirt and impurities in, which can cause long-term damage to the engine.
