Why has my MPG suddenly dropped?

Why has my MPG suddenly dropped?

Here are some the main causes for a sudden drop in gas mileage: Bad oxygen sensor and air filters-in all forms will affect the fuel mixture and your fuel efficiency. Dirty, Bad or leaking fuel injectors or fuel pump-will also affect the fuel mixture and lead to slow acceleration, loss of power and fuel inefficiency.

Are car trip computers accurate?

All new cars now have a way to zero out the MPG average. On some, it can be automatically reset when one fills up the car. On all the rest, one simply zeros it out using the trip computer to restart the average. Over the full course of a tank of fuel the MPG average displayed should be pretty accurate though.

How is the gas mileage reported on a Prius?

Filling up at the pump and calculating the gas mileage manually is more accurate than reading the onboard fuel economy meter. The fuel economy meter, found on most cars these days, is overly optimistic by 5.5 percent. The fuel economy reported by the fuel economy meter on the Toyota Prius was sometimes off by 14 percent or 6.8 mpg.

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).

What should my mpg be on my car?

One low tire can kill fuel mileage so tire pressure can be a consideration. You should be getting about 29-31 MPG overall with this car. If it was just one 27 MPG tank, then I would chalk it up to an anomaly, and it would still in the ballpark.

How can I determine my gas mileage accurately?

Reset the trip odometer to zero and record the mileage when you fill up next. Using that and the gas volume on your receipt, you can determine the gas mileage accurately. I don’t know how you determined gas mileage and thought I’d mention this if you do it the other way. ok4450 July 6, 2016, 2:38am #9
