Prius (Gen 2) Fuel :: 2005 - Fuel Consumption Increase After Service And New Brakes
Nov 2, 2013
So, my 2005 Gen II Prius went for a scheduled service on Wednesday, 70k miles, Toyota main dealer. They called and said it needed new front brake pads and disks, I was surprised but gave the go ahead. There would occasionally have been a mild squealing sound from the brakes at very low speed so I accepted the pads might need replacing, I was surprised the disks needed replacing but it hard to argue about brakes, especially as I only have the car a year (I'm the second owner and it has a full Toyota service history). It had a "major" service, new spark plugs, new front brake pads and disks.
Since collecting it I've noticed that the engine seems to kick in more often and needs higher revs. The fuel consumption seems higher, normally mid 50's MPG (imperial gallon) now 35MPG. However it hasn't been driven many miles since its been serviced so its a low distance for calculating MPG. I've also noticed that the car seems to slow more quickly without applying the brakes, a regularly driven hill that I coast down at 48kph now only gives 35kph. Also, if I drive on a flat road for a mile or 2 and coast to a stop the front brake disks feel VERY hot, way too hot to touch, drivers side more so that passenger side.

Since I got Prius I've noticed that driving at 50mph returns 80+mpg , 90+mpg if I let it gently glide at -1mph per 1 mile. As it gradually slows down, the mileage starts to decrease. By the time I get down to 45 mph the mileage shows around 70mpg,
I get down to 40mph, I'm only getting 50mpg. When I keep my speed between 40 and 45 I get about 52-55 mpg for the day. If I keep my speed between 45 and 50, I get 55-60mpg for the day.

When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.

What kind of mpg increase one would see if they were to increase the tire pressures from recommended (35 F/33 R psi) to max (44 F/ 42 R). Any stats of tracked?

I changed the throttle body , PCV , clean the EGR tube and put new gasket in my Prius B 2010 hybrid.
The car was burn oil 1/2 liter per 1500km and since I changed the throttle body I noticed that the car burn 1/2 liter per 400 km .The job by the dealer.
Is there any problem in the installation?

Ok I read about replacing a bad or ailing 12v battery (mine was original - 2007 - and resting at 10.1v) and an increase in mpg's. But I didnt expect this kind of increase!
I bought the car 9-14-12 and had been driving it very hypermilishly...lol...and getting 48mpg average.

How do I turn the "fuel consumption comparison" off? I want to see only the quantity and price off the gasoline I have consumed.
There isn't a "disable" feature, so I am guessing I set it to 0 mpg?

Is it ok to shift into neutral when the car is moving?

I have the 2010 prius V with the 17in tires. I love the rims on them Vs the hubcaps on the other models.
HOwever I have read that it is hard to hypermile with the 17in rims. SO I was trying to figure out what I can do to raise that MPG up there. I have noticed that my prius does not glide well.
I have 2LBs more air in the tires then it says on the side. mine say 60LB so i have 62.
My only thought is to running Amsoil 0w30 oil and amsoil synthetic tranny fluid. I know on a regular gas car you can up your MPG at least 2 MPG or more.

I bought a Prius 2nd Generation (2008) Japanese domestic). When I go to Consumption view it shows blank Graph for the past 5min - 30 min graph. How to fix this.

I kept a record of every drop of fuel used in my 2008 Gen II Prius. It was easy with only two simple screens: Energy and Consumption. After writing down the numbers I reset the Consumption screen at every fill up. I entered these into a spreadsheet that did a bunch of calculations telling me all kinds of interesting things.
Now to my new 2014 Prius v Two. I'm confused regarding all the new information available. (A good thing) Which screen and number am I looking for that is equivalent to the Miles and cumulative MPG on the old Gen II?
Would like to sort this out before my first fill on the new car.

Yesterday we were on a 10 hour trip and the engine was acting oddly; when braking, the engine sounded just like the engine brake, but the MPG indicated that it was consuming fuel (engine brake does not consume fuel). When braking, the engine would sound, and the MPG indicator indicates fuel consumption, it would go down to 50, with the heavier braking, like when stopping... then at a certain point it would suddenly stop
It seemed to happen most times but not always. This issue didn't happen before.

how much fuel is consumed during a typical warm-up period for the Gen III? I realize there are variables related to ambient temperature etc..
my interest is to get a baseline consumption figure to compare warm-up saving devices/techniques against.

Just bought a 2012 Prius Three last Friday. The MFD (upper display) shows an average of about 53 mpg so far, and the corresponding 1 & 5 min bars seem to make sense (we have an 07 TCH so we're reasonably familiar).
But the Display Audio unit (6.1 inch) Car>Consumption graph seems to show 100mpg most of the time/most bars. That can't be right and it looks nothing like the MFD display. What am I missing?

The 30 minute fuel consumption yellow bar graph doesn't display on my 2006 Prius. It shows my current mpg but not the previous 5 minutes sections. It also doesn't show the green battery regeneration icons. Everything else seems to be working fine.

Just bought a used 2010 prius II about 2 weeks ago with 10000 miles on it. As I've been driving I feel the consumption display is misleading. It averages around 52-53 mpg, but I'm only getting about 480 miles before I'm running on empty. The tank capacity is 12 gallons right? If so I should be getting at least low-mid 500's before I need to fill up again. Hopefully I'm calculating something wrong and its not the car itself.

I have a 2005 Prius with 130k miles on it. In Oct 2012 I took it to the Toyota dealer for 120k service. They performed the following:
120k service
Replace serpentine belt
Clean and adjust drums
Replace cabin/hepa micro filter
Replace brake system fluid
Since then my car's mpg has dropped from ~45 to ~35mpg. I specifically notice that the pickup is completely gone and that it seems to "drag" pretty badly when starting from halt (stop sign, a light etc). Once it gets up to ~40mph, it appears to be doing all right in terms of mpg. What could be causing the "drag" and mpg drop?

My wife and I were driving around town the other day. While merging onto the highway we hit a nail. I put the donut on and went to TiresPlus where I have gone since I started driving. I had been thinking about replacing the front tires due to wear and the nail wen in the side on the rear. Anyway I purchased 4 Firestone Affinity Touring tires and went on about my day. My wife drives 100 highway miles a day and then does some city driving. This week she has lost about 5mpg's according to the display average. Also the service light has come on. Can this all be tire related?

Wondering what could cause an increase in fuel economy. My GTI has been running at 29 +/- MPG since the day I bought it, but no higher than 30. I took it out for a ride on Sunday after I changed the front brakes Saturday. The dash tells me it's running at 34. So I filled it up and manually clocked it on a 50 mile trip. I refilled at the exact same pump - just to remove any error. And what I calculated is that the computer is right.
There is no loss of power. However, I've been fighting intermittent misfires on cyl #1 and #2. the misfire on #1 has all but gone away after finding out the coil wasn't sitting right and the spark had loosened up. I've tracked #2 down to either the injector or carbon. I'll be taking care of that next weekend.

We have two counters on MFD (1-trip data and 2-accumulated data), none of them show the gas consumption.
Every time I stop at gas station I have to divide distance by average gas consumption to know, beforehand, how many liters to top up the tank.
Question is: Is it possible to use VCDS to make the MFD show that information once it is obviously known by the board computer?
