Engine in need of tune up
From time to time, engines may fall out of their optimum performance range. This can be the result of poor ignition timing, improper fuel/air ratios, dirty or worn spark plugs,or valves that open and close at the wrong time. When this occurs, more fuel may be consumed. Tune ups were more common in older vehicles in which a distributor was used. While they may still be required in newer vehicles, they are not as frequent.

Vehicle Consumes More Fuel
If the engine performance has diminished, and more fuel than usual is being consumed, the engine may need a tune up. The timing may be off, causing a loss in power and waste of fuel.
The spark plugs may also be firing later, which reduces the engine power. The vehicle would have use more fuel for the same power, and thus reduce fuel economy.
