Why is my car getting terrible gas mileage?

A bad fuel injector or dirty/old fuel filter can drastically affect the flow of fuel into the engine. A fuel system problem is one of the most common causes of poor gas mileage. The more you run your A/C, the lower gas mileage you will get.

Can old oil cause bad mpg?

Running an engine on old, sludgy oil will cause a decrease in fuel economy. Without the right viscosity, the oil loses the essential ability to get where it needs to go in the engine. The engine runs hotter and less efficiently, robbing the engine of both gas mileage AND horsepower.

Does cruise control save gas mileage?

Absolutely. If you’re cruising along a mostly level highway, electronics generally are far better at avoiding the little speed-up/slow-down events that are inevitably caused by a weary accelerator ankle or an inattentive mind.

Do new cars get worse gas mileage?

A. My experience with many new cars is that they don’t return the projected fuel economy until the engines reach 5,000 to 7,000 miles, some engines even more. The gasoline that we use during cooler weather and short trips can have a dramatic impact on your car’s mileage.

Does a full tank get better mileage?

No. You would get a very small amount of better mileage in the second half of the tank due to the fact that your engine has to haul a half tank less of weight around. The functioning of the engine doesn’t change due to the amount of fuel in the gas tank, except when there is no gas in the gas tank.
