Prius (2004-09) Fuel :: 2006 - Decline In Miles Per Gallon
Jul 29, 2012
Recently, my 2006 has been showing a decline in MPGs. I purchased a K&N filter several months ago hoping that it would work in getting better MPGs. I also watch my tire's air pressure, but the MPGs still fall off. I used to get around 43mpg in town and 45 to 47 on the highway. Now, I'm lucky to get 39mpg no matter where I'm driving.
I've been thinking of changing the spark plugs since I'm sort of grasping at straws. Also, someone told me that the older the battery pack (NHW20) gets the less MPGs I can expect. Maybe true maybe not! My Prius has a little over 60,000 miles on it and it shouldn't be loosing MPGs.

We picked up our 2009 prius about a month ago from a local dealer. At the time it was getting about 52 miles per gallon. Since then, we have driven about 1000 miles and now we are getting only about 41 miles per gallon. Are we doing something wrong that made the MPG drop over 10 miles per gallon.

My 2007 (with Nav package and aftermarket Sirius radio) recently started losing channel settings on the Sirius (not on the FM radio!), the dash clock resets, and, recently, the miles-per-gallon and miles driven since last fill-up reset to zero. These events are sporadic, but have started occurring more often. The dealer seems unable to figure out the problem.

I just bought a 08 Screw with the 5.4 3 valve, 4x4 with the 373 gears, and 25,000 miles on it. I love the truck, but what is the best that you have gotten for mileage on your trucks with the 373 gears? Does it do better at 75 mph or 55? I haven't checked mine yet so I am wondering what to expect...

I bought a 2012 Prius new and averaged just under 53 miles per gallon for the first 15,000 miles regularly. I have a long commute so my driving mix of city/highway is pretty consistent. When starting the car one morning there was a fairly loud series of clicking sounds from the engine compartment, which then stopped. From that point forward the mileage has dropped to just under 50 mpg. Same driving habits. I am bringing the car if for it's 20,000 mile check up shortly. Any ideas if something happened to the battery I should ask about? It is still under warranty.

My 2000 corolla has consistently gotten 35 MPG until last month, suddenly I've dropped to 18-20 miles per gallon, a friend suggested fuel filter fail, but i can't discern if it has an external one...

In the last month, I've been getting less miles per fill up. Previously the gas light would hit 1 bar around 400 miles. Now its hitting 1 bar around 350-360 miles. But when I fill up, I only fill up about 8 gallons so I haven't lost any gas mileage. It feels as if the tank shrunk on me.

I bought a 2005 Prius with 128k miles on it a month back. I have driven around 900 miles on it and the average shows as 49 mpg. Is it okay or am i getting less? I normally drive 40 miles a day(20 miles either way) to office and back home, total of 50 minutes with 25 minutes either way, including both Uphill and Downhill both ways. Driving includes 10 minutes on city with frequent stops and 15 minutes on highway either way.

So, I've now had my 2015 F250 6.7 Diesel for about 2 weeks and I just turned over 1000 miles (damn I love driving this truck). And, I'm dying to find out if my mpg experience coincides with any other truck. With no load I am consistently getting right at 22.5 mpg at 70 miles per hour. With all in town driving and no load I'm holding right at 15 mpg. And I've noticed something else that seems odd. I'm actually getting a little worse mileage at 60 and 65 than I do at 70 miles per hour. What is going on there? Do these engines get a little better mileage as they get more miles on them?

Been driving for 3 days now for a total of about 100 miles from a full tank averaging 50 miles per gallon. I noticed the gauge still shows FULL. Not even a bar below or something. Is there anything wrong with my gauge?

Yesterday when I tried to fill up my 2007 Town and Country I found I cannot put more than about 1/2 gallon at a time before the pump shuts off. I have the problem at multiple stations/pumps so I know it is a problem in my car.
I have heard this could be a clogged charcoal canister so that the air cannot get out of the tank as the gas is going in. Where this unit is located on the Town and Country? Could there be another issue? A week ago when I filled the tank I had no problem, but yesterday it took a very long time to fill up from empty.

Really starting to get a little frustrated and would love input.....
Owned our PIP for almost a month now. First week, fully charged EV miles were showing around 13.7. 2nd Week, around 12.2, 3rd week, 10.5 and now this week it's gone from 9.6 to 9.1???

On page 93 of the Prius PHV Owners Manual, under the heading "Capacity reduction of the hybrid battery (traction battery)" is the following language:
"By observing the following precautions, battery charge decline can be suppressed."
"Avoid driving near the top speed for EV driving ( --P.40)"
To me this says don't drive EV 60 MPH, don't drive EV 55 MPH, maybe 50 MPH is OK is not uphill, probably 45 MPH is OK.
The manual also says "Also, if the hybrid battery (traction battery) capacity reduces, the EV driving range decreases. However, vehicle performance does not significantly become worse."
I wonder if this is a statement that the warranty will not cover capacity decline?

Yesterday I measured the mpg going uphill.
It was 22.2 MPG going Uphill 4.7 Miles from elevation 50ft to elevation 1250 ft. It is more than 50% drop in the mileage.
Do other cars ( non-prius / non-hybrid ) too drop 50% mpg going uphill ?

How many miles does it say you can drive after you fill up? Mine says 334 and that's what I'm getting. I want to hit 400 for a tank and can't.

Started about a month ago, no speedometer or fuel gauge (the display up on the dash). So, somewhere I found out about unplugging the 12v battery and that worked...for a while! After a few times doing that, I read somewhere that it is a sign that the 12v battery is going. So, I took it in to the local auto parts store, they tested it and said it was good.
I bought one anyhow since it was about 3-1/2 years old. That worked for about 2 weeks, but now it's back! I've unplugged the battery and again it has ( temporarily ) fixed this issue. The other thing that happens is that it is difficult to turn off and requires you to hold the power button for an extended period of time. I guess part of my problem is I am not sure what to call that display and my searches are coming up with all sorts of things. I have about 160,000 and have had no problems.

Just wondering about the "miles to empty meter", should I disregard it when I have high mpg? (50-60 mpg)

I have been a happy 2009 Prius owner for 2 weeks now but am a bit concerned with the fuel capacity I have been experiencing.
The first tank I went to fill-up when there were three blips left on the fuel guage and the tank only took 5.7 gallons. I wrote this off as I did not know how much gas was in the tank when purchased (the guage was on full). The mileage was around 250 miles.
Today I had to stop again for gas. There were 3 blips left on the guage and the tank again only took 5.4 gallons. I am not concerned about the MPG, but with the tank only taking around 5 gallons.

So I'm now on my second week with this 2012 Prius and still trying to learn how to roll in it.
I filled up my very first tank yesterday (dealer gave me a full tank when I bought it) and the miles remaining display said 424 miles after I filled up. Does it display 424 on all Priuses by default?
The first tank gave me right around that many miles before I filled up - the miles remaining display said I had 9 miles left so I got too scared to see if I could go farther. But when I filled it, I only filled just under 10 gallons - does that mean there's more miles for me to drive, despite that remaining miles meter?
And...am I getting pretty bad fuel economy?
