Prius (Gen 3) Fuel :: Mileage Drop (0.8 Mpg) While Not Moving
I turned on the car, CONS showed 56.0mpg,
backed out of the garage (about 20 feet) 55.8 mpg,
waited for the garage door to close 55.0 mpg (ICE started),
got to the end of the street (about 200 feet) 54.0 mpg
outside temp was 51F, humid, cloudy
had about 90 miles on new tank of fuel
I know you get big swings in fuel economy when you reset the trip on fill ups but I just thought it was funny that the mpg would drop 0.8 mpg while not moving.
Prius (2010-12) Fuel :: Sudden Drop In Gas Mileage
I commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.

I am using a 2012 Prius and I was running around 23KMpL average. For sometime I am seeing my mileage around 17 - 18 KMpL. What could be the reasons for this ?
The only change happened in between is that I had a accident which I had to replace the front buffer.
Prius (2010-12) Fuel :: Gas Mileage Drop - Averaging Between 41 And 43 MPG?
I bought a 2010 Prius II (150,000 miles on it) about two weeks ago. In that time the car has been averaging between 41 and 43 MPG according to the computer, and I calculated 41.3 MPG at my last fill up. I am concerned about the MPGs. I bought a brand new Prius in 2012, it was a III model and '12 year. That car always got 48 highway, and 50 in the city. From what I understand, the 2010 and 2012 models have the same engine and transmission set up and the only difference may be the software.
So my questions are; why am I getting 7 to 9 MPG less than my old (newer) 2012 Prius? What to do to get better mileage, but what actually worked? My checklist of repairs include; check 12v battery, change out spark plugs, just changed air filter, check brakes, oil change (using Mobil 1 full synthetic 0w-20), what else should I check/replace/update,
Prius (2010-12) Fuel :: Why Does Mileage Drop At Least 2 Mpg When Raining
It seems that my mpg gauge always drops by at least 2 mpg when it's raining, even if one goes slower because of the rain. Why is this?
View 19 RepliesPrius Plug-in 2012-15 :: EV Mileage Sudden Drop
I was driving up a hill today at about 30 mph with .9 miles remaining showing on my EV battery meter when all of a sudden it drops to 0 EV miles remaining and shows only 2 of the battery level bars (which is very very low), and the engine of course turns on. What happened?
I promise I did not push the EV power bar over its threshold. I monitor that like a hawk. I also know for a fact that it jumped from .9 to 0, because I watch that part like a hawk. This part of the trip is near the end of my drive home and I've done it about 50 times so far with no issues. With .9 miles left at that point on the hill I have always been able to make it to my driveway with .4 or .5 remaining, so this is very odd.
Hyundai - Elantra :: 2012 - Sudden Drop In Gas Mileage
Why all of a sudden the mileage indicator on my 2012 suddenly dropped about 5 miles/gallon, both highway and around town? The car has only 9000 miles on it. Has there been a service bulletin regarding the "Eco'" mode? Having the "Eco" mode on or off doesn't seem to make a difference.
View 8 RepliesPrius (Gen 2) Fuel :: 2007 - Mileage Drop By Over 20% When Put Summer Tires
This Easter I put summer tires on my "new" (owned about 4 weeks) prius -07, and cleaned and greased brakes.
With winter tires (almost new Nokia hakka xx, stud less) I got 4.5 l/100km (52mpg) easy and 4.2 (56mpg) at best, now I get 5.5 (42mpg) and 5.3 if I struggle, if I relax and put cruise control on I get 5.8 (40mpg). I travel 100km to work every day.
Summer tires is Michelin primacy (about 2 seasons?) pumped to 3.0/2.8 bar (over inflated).
Brakes don't seem hot after drive and they was really clean and easy to move after my service so my guess is that they work fine...
Mileage went down over the weekend so I see a clear link.
It was more fun trying to hypermile at 56mpg aiming for 60 then it is at 42 aiming for 45...
12v battery charged, just in case. Still same temperature out 1-8 C. Oil and all filters changed first week (will change trans axle oil in summer). Travel to work got 4% shorter so tire size must be a small reason to the +20% problem.
Prius (2010-12) Fuel :: New Tires Lead To Drop In Gas Mileage
Last October I needed new tires, so I had Michelin Defenders put on my 2011 Three in place of the OEM Firestones. The Michelins perform well and are nice and quiet, but...
My gas mileage (both indicated on the dash and calculated) has dropped by about ten percent. In researching the two brands of tire, I found that the OEM Firestones are rated at 836 revolutions per mile, and the Michelins are 839. I'm wondering if this is the reason for the apparent change in mileage.

View 1 RepliesAccent RB (2012+) :: RPM Drop Normal At Low Speeds?
I recently bought a 2013 accent and i have only one issue, but it is quite annoying. When i try to maintain a constant speed lower than 35 mph, the rpm will drop about 1000 and then go back up causing a pause in forward momentum, almost like it's tapping the brakes itself. I took it to the dealer and since the computer was showing no codes they swear this is normal for an accent. I say no way since it didn't do this when i test drove it or for the first week i had it.
View 1 RepliesPrius V Fuel :: 2012 - Mileage Is Down To 30.6 MPG
My 2012 Prius v (lowercase v) has about 80,000 miles on it, my work commute is 180 miles round trip daily. I had been getting 40-44 for about the first 18 months of owning/driving the exact same commute. In February I noticed when I filled the tank that the range showed around 370, which seemed odd, it was always over 400. I started tracking my mileage and it declined quickly. By mid-March I was getting a range of 320-340 with each fill up, and calculating MPG of 29-31. The dealer has had the vehicle for over a month now and can't find "anything wrong with it". Ummm, the MPG has dropped about 30%, isn't that something wrong?
View 19 RepliesTiguan :: 2012 - Poor Fuel Mileage?
My wife and I just purchased a 2012 SEL front-wheel drive. Our first tank (mixed use) was 19 MPG. We took the vehicle on a roadtrip this weekend that was 95% highway driving on mostly flat Texas roads using cruise control as much as possible. Our best tank was 23.3 which was achieved driving 70-75 MPH on I-20. Is this consistent with what others are seeing? My mileage figures are at the link below. Note, all values are calculated by me, not the MFD that reads about 1 MPG high.

Accent RB (2012+) :: Engine Shudders When Takeoff - Revs Drop To Almost Around 300 - 400
After the car has been sitting for a while (say about 8 hours or so) I will turn the car on and I will always wait about 30 seconds or so before moving off just to let the oil start moving around. If I go to take off the engine shudders and sounds like its about to stall and the engine revs drop to almost around 300-400 revs then suddenly come back up.
Now I drive a manual car and I know there will be people there that will say I obviously cant use the clutch very well. This happens from anywhere from a flat to a decent incline in rain or sunshine, night and day, and all different external temperatures.
But that isn't all, the kicker is if I give the throttle a quick jab to bring the revs to around 1200-1500 revs, go to take off and the car is fine. ONLY happens once after sitting around for a while, basically after the engine has a good time to cool off to completely cold. Little side note, this has been getting more frequent over the last 3 months.
Scion - Xb :: 5 Speed - Gas Mileage Varied And Fuel Mileage Increased
I've had my XB 5-speed for nearly a year and 10000 miles. It as been dead on reliable and fun to drive. My gas mileage has varied from 26 to 31 in mixed driving and from 32 to 35 on the highway. I use premium fuel only because I can get it without ethanol. My fuel mileage also increased a couple of mpg due to getting the power robbing ethanol out. True it is probably not enough to offset the extra expense but I like not having the stuff in my car. My only dissatisfactions has been with the transmission gear ratios. They are way to low. This torquy engine could easily do with a ratio that would drop about 500 rpm for more relaxed highway cruising.
As it is, though, my XB will go up any hill or long grade without breathing hard! Another is the instrumentation. I don't mind the center mounted set-up but speedometer and trip meter for mpg ratings are both inaccurate. My speedo reads about 2.5 mph high and the fuel mileage read out has about the same error, also on the high side. I have the stock 16" tires. The clutch has a narrow engagement band and can be difficult to be smooth on. The car is fairly quiet, is comfortable and this years hot, humid summer has shown it has one of the best air conditioners I have ever experienced in a car. I thought it might be an electric unit rather than a belt driven compressor because there is absolutely no perceived drag when the compressor kicks on.
Passat (B6) :: Sudden Drop In Gas Mileage?
I have an 08 2.0T and it just suddenly had a huge drop in gas mileage. I recently had new tires put on and an oil change (about 35k miles). getting closer to 40k miles now and wondering what could be causing this. Usually I get about 30-33 mpg easy on the highway. Now I'm getting 24-26 mpg. Already checked the tire pressures. they're to spec. no gas leaks from what i can see.
