How does MPG affect fuel economy?
How does MPG affect fuel economy?
Excessive idling decreases MPG. The EPA city test includes idling, but more idling will lower MPG. Driving at higher speeds increases aerodynamic drag (wind resistance), reducing fuel economy. Towing a trailer or carrying excessive weight decreases fuel economy.
What causes a car to drop in gas mileage?
There are dozens of problems that can lead to a drop in gas mileage, some of them are serious and some can be easily corrected. Here are some of the more common issues that can affect the fuel efficiency of most cars. When the fuel system does not work as designed, the efficiency level is likely to reduce.
What causes a sudden drop in fuel efficiency?
If the CEL is on have the codes checked and it will probably lead you to your problem. Such a drastic drop in mileage is often associated with a bad 02 sensor. I’ve had them go bad and cause a 25-35% drop in fuel efficiency. keith July 6, 2016, 2:38am #4 Did you have anything done to the car just before the mileage dropped?
What does it mean when Your MPG drops 20%?
BTW, there is a code if the ECT (engine coolant temp) does not come up withing a certain time frame. You could also have a fuel leak. My 2010 FIT dropped 20% immediately upon moving to a much colder climate. I checked tire pressure and changed air filter, changed gas stations. Still off by 20% ( 10 miles per gallon).
Why is my Subaru getting worse gas mileage?
Clogged Fuel Filter: A clogged fuel filter will also cause problems with gas mileage. The fuel filter screens out contaminants in the fuel, and over time it will become clogged. Fuel filters need to be replaced periodically.
What causes a sudden drop in gas mileage?
Such a drastic drop in mileage is often associated with a bad 02 sensor. I’ve had them go bad and cause a 25-35% drop in fuel efficiency. Did you have anything done to the car just before the mileage dropped? A drop like this has to have an assignable cause, and it often traces back to a maintenance that was just performed.

How can I increase the fuel mileage of my 4.3 V-6?
Making these engines more efficient is simply a matter of adding a few bolt-on accessories, though it is unrealistic to expect the fuel economy of four-cylinder engines or hybrids. The first and most obvious way to improve the fuel economy of your 4.3 V-6 engine is by improving the quality of the air that the engine consumes.
Why did my mpg drop on my 2010 fit?
My 2010 FIT dropped 20% immediately upon moving to a much colder climate. I checked tire pressure and changed air filter, changed gas stations. Still off by 20% ( 10 miles per gallon). Is it just the cold environment? Car is parked in a garage when not driven
