Volvo models are designed to perfection. They guarantee comfort, class, style and everything in between. Sometimes though, they experience minor setbacks for one or two reasons which are often easy to fix. It could a glitch that occurs as a result of wear and tear or even bad driving habits. Take poor gas mileage problems that crop out of nowhere. They are easy to fix, but before fixing the problem, you will have spent some time trying to figure out what cause it in the first place. This is never easy especially if you are trying to do the troubleshooting on your own. Your best bet is to find a licensed and experienced Volvo mechanic to help you fix the problem. Here is why you could experience sudden poor gas mileage.
Sometimes there’s really nothing wrong with your vehicle. This means the poor gas mileage problem can be traced back your driving habits. Driving beyond 120km/h will for instance result in poor gas mileage. Idling too much can also cause poor gas mileage so by all means avoid leaving the engine running as you wait for someone or for a service. Then there is impulse driving which is without a doubt as bad and as dangerous as over speeding. Engaging gas and brake pedals frequently and without a good reason will certainly lead to excessive oil loss. The only solution here is to learn how to compromise on the thrill that comes along with acceleration and revving.
Tire issues can force your car to burn more fuel than it should. Low pressure, uneven and misaligned tires will force the car to struggle moving. The engine will simply be forced to work harder and burn more fuel. Checking tire pressure on a regular basis as well as taking the car for alignment inspection is the only solution you have here. Then always remember to inflate the tires according to your car’s manual. Overinflating will give you hard time while driving as it will make the car unstable.
Low Oil Levels
Enough oil means ample lubrication in all car components that should run smoothly. With low oil levels in your car heat and friction become inevitable inside the engine. This will damage not just the engine but other parts that need oil to avoid heat and friction. The engine will simply be forced to burn more fuel than it usually does when there’s enough oil in the system. This is exactly why you should change your oil after 6,000 to 12,000 miles depending on your Volvo model.
Dirty Oxygen Sensor
The oxygen sensor measures the level of exhaust gases as the leave the combustion chamber. This is important because the Electric Control Unit (ECU) uses the data collected by the sensors to determine the amount of fuel that the engine needs. A dirty oxygen sensor can easily err in measurement and result in abnormal fuel consumption. A defective mass airflow sensor can also cause the same problem. The solution here is to have these devices inspected and fixed by a licensed Volvo mechanic.
