Owning a car could be costly, so lowering ownership expenses may make things less expensive for Phoenix drivers. Improving fuel economy is one such step. Take that as a reason why it is vital to change a vehicle's motor oil on time. Dirty, aged motor oil might reduce fuel economy more than believed.
Perhaps requesting an engine cleaning would be wise. Oil sludge in the engine could reduce fuel economy considerably.
Another factor that could impact fuel economy is the weight inside the vehicle. An overloaded car will burn more fuel to power the engine, increasing fuel costs. The impact on the engine might not be positive; the engine could suffer premature wear from all the hard work.
Asking the service department at Bueno Used Cars to check the tires may help. Underinflated tires could create a drag that burns more fuel.
