Prius (2010-12) Fuel :: High Temps Dropping Fuel Economy?

While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.

Prius (2004-09) Fuel :: 2008 - Sudden Drop In Fuel Economy - Water Leak?

I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).

Prius (Gen 3) Fuel :: How Fast To Accelerate For Maximizing Fuel Economy

I am wondering about how fast to accelerate for maximizing fuel economy. I understand with the P&G approach that you don't want to get up to speed too slowly. The question is whether it really is more efficient to go ahead and get up to speed or stay within the ECO guidelines? In particular, I find that getting up to highway speed especially that it can take quite a while to get up to 70 mph without having it going into the power range. It seems like it is better to get up to speed and then back off to go to the high efficiency mode.

C/K :: 1997 K2500 Suburban 4x4 Auto 454 - Fuel Gauge Reading Full All The Time?

As title really, it's a 1997 K2500 Suburban 4x4 auto 454. I haven't used the sub for a while but got in it the other day and it fired up all fine and I then looked to see what fuel I had left only to see the needle right over to full. Well I know it is nearly empty and I've never had the guts to fill the thing or should that be had the funds to fill it to the top, so know it is wrong. I got under the truck and unclipped the rear most wiring connector just infront of the fuel tank but the gauge still reads full. I suspect either the gauge is faulty (so is there anyway of checking) or the sender in the tank or wires in the tank have shorted (again anyway of testing without removing the tank).

Prius V :: Best Way To Drive For Fuel Economy

I have a 2013 Prius V and my mpg averaged about 43. Now after about 13,000 miles it has gone down some to more like 41-42 and even 39. Once on a mostly highway trip it was down to about 34. Last summer it got 51 mpg in Colorado!

How to get better mileage. I once heard about a feathering technique with the accelerator but I don't know if I understand it.

Prius (2010-12) :: Fuel Economy Seems Better With Almost Full Battery Level

I got prius i-tech Australia (should be IV or V in US). I just noticed this morning that my fuel economy is better when I got 6-7 bars on battery level, and worsen if i only got 2-4 bars. Is it just my imagination or any explanation for it?

Prius (Gen 2) :: Loss Of Fuel Economy After Electric Water Pump Replacement

After my electric water pump was replaced under the recall my mileage went from 45 mpg to about 30 mpg. Part of this might be due to new tires and cold snowy weather (CT !) but I have never seen such a drastic drop in performance (2005 Prius).

Prius (Gen 3) :: Front Brakes Dragging Excessively Causing Lack Of Power And Poor Fuel Economy

Our 2010 Prius just had the brake booster recall done and I also installed new pads and rotors. The car now has issues with the front brakes dragging excessively causing lack of power and poor fuel economy. There are no codes and everything else checks out okay, the brakes function fine. Is there anything on these cars that would cause brake drag after a new brake install? I just want to ensure there isn't something I can do before I bring it to the Toyota dealer.

Prius C Fuel :: Low MPG Reading - Reset?

I bought a Prius C package 4 in Silver with Black interior with 16 inch allow wheels yesterday, I really like the cool technology and the look of the car. I bought it from a dealership roughly 160 miles from my home. Once I purchased it and was driving back on the Florida Turnpike, I first started of getting 43mpg, I was in the higher green area of the Eco meter, basically I was pushing the gas pedal and it was reading roughly 90 percent of the Eco meter is being used, I was driving at 78-83 mph. After an hour or so, I checked again and to my surprise it was reading 32.2mpg, I was really concerned, and slowed the speed, but it didn't change the mpg at all. After another 15 minutes, the mpg raised .1 every 2 minutes or so until I got home and parked my car I was getting 35.8.

This morning I woke up, got into my car and started driving for about 20 minutes, it is still reading the same 35.8. This is with me driving around 50 percent of the Eco meter

I'm concerned, is there something I'm doing wrong, do I need to reset this mpg, if I do, how do I do that.

Lexus SC430 :: Clock Resets Every Time When Turn The Car Off

So everything in my car has no memory issues but my clock always says 1:00 ... when I start the car....

I have tried another control unit (the climate control, nav screen, etc buttons) where the clock is located to see if I had a bad unit and it still did the same thing.

I have a brand new battery from Lexus and everything else in the car seems to be fine....this was an issue before I bought the new battery.

Chrysler - 300m :: Gauge Will Randomly Drop Down To Empty / Low Fuel Light Turn On Then Go Back To Correct Reading

MY 2000 300M has a problem with the fuel gauge. When over 1/2 a tank and just under the full mark the gauge will randomly drop down to empty and turn on the low fuel light then go back to the correct reading and will do this over and over again. my mechanic has looked at the car believes it's the sending unit. Just wanted a second opinion before I spent the money for a fuel pump module for the car.

Prius C :: Fuel Gauge Not Showing Correct Reading?

Driving on my original tank from dealer today from Upstate NY to NYC. On the way my C had 4 bars to begin then went to 3, then 2 after about 90 miles of traveling at avg of about 55mph. I watched the cruising distance go down to 1 but I still had 2 bars on my fuel gauge (and my crusing distance was conservative compared to my mpg reading the whole trip, which was hovering around 58mpg).

The gauge went from 2 bars to one flashing bar in about 1 minute. I pulled into a gas station about 2 miles ahead and put in about 5 gallons... this put the fuel gauge up to 3/4s or about 3 bars above the halfway mark. What gives? I know there are fuel gauge issues but I thought with two bars I would have had plenty of time before I needed to fill up on these roads with these mpgs.

Golf/GTI VI :: Possible Causes Of Increase In Fuel Economy

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.

Passat (B6) :: 3.6 Fuel Economy Dropped

I have the 3.6 and it has been great on fuel economy up until last week. I was averaging about 26mpg and getting near 20 mpg around town. Now my fuel economy has dropped to 15mpg city and 25mpg highway putting the overall MPG down to around 20. What happened? Did I get a bad tank of fuel or is it time for new spark plugs? The car has 34k on it; and when I checked the plugs at 28k they looked like new and gapped to within .002 of the spec.
