I recently bought my new car through a family friend.2000 Hyundai accent auto owned by a 90yr old grandpa since new with only 45k on the clock. im used to driving a manual so I don't know if its just me not used to it but when I slow for a corner to say 15-20km/hr and accelerate out the transmission remains in 3rd gear unless I give it a really good prod then it changes to 2nd or 1st. the acceleration when It does this and stays in 3rd is ok but I just wonder if its normal or is it just burning out the torque converter. also im only getting about 380-400kms out of a tank when driving the same route my old 96 pulsar used to get 550kms from the same fuel. is this normal I would have thought this new car to be using if anything a little less.

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.
Elantra MD (2010-15) :: High Fuel Consumption Above 2200 Rpm?
It's great on gas below 2200 rpm. Averaging 34 combined. However whenever I'm in a situation where I need to accelerate, such as beat the yellow light, up a hill, or pass someone and I shift to a lower gear I lose 1-2 MPG at the drop of a dime. And then it takes forever to recover. What is going on here? Is the engine being flooded with fuel?

Accent LC (2000-05) :: Gas Consumption Too High 7.3 Km Per Liter - Spark Plug And Air Filter Replaced
I have a hyundai accent 2005 sedan (automatic transmission). The vehicle is a NON-US model. My gas consumption is approximately 7.3km per litre which is very high.
The spark plugs have been replaced , tires are at 30psi , and air filter is new. The spark plug cables are also new. The obdII device does not detect any issues and the engine check light is also off.
Prius (2010-12) Fuel :: Display Consumption Bars Too High?
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?
Elantra XD (2001-06) :: High Fuel Consumption And Preventive Maintenance
I have a 2002 Elantra GT, is consuming 22 miles per gallon, one of these days the car was alarmed with a check engine, the mechanic checks to see if he had a loose wire, then removed the battery, put it on again and check engine disappeared. Following this, the car is doing 30 miles per gallon. After 5 hours the alarm appeared again, we scan the car and gave the code P0420. These days the car has been decreasing again the miles per gallon.
I bought the car with 186.000 miles but the person who sold me the car said he had 68.000 miles, the board was stolen and damaged something, then had to buy a Yonker the board and that board came with the mileage, is this possible?
What is suggested to improve the fuel consumption?
It is possible to know how much mileage the car has traveled in reality?
With so many miles traveled, which recommended preventive maintenance?
This error code says that the catalyst has to be replaced but can also be a leak or may be some of the oxygen sensors.
Elantra XD (2001-06) :: TPS Failure Symptoms And High Fuel Consumption
I'm experiencing some TPS failure symptoms and high fuel consumption.... I've unplugged the ecu harness to measure the voltages, measured a constant 6v on the return signal wire while it should be about 0v. While the input voltage is normal 5v. A strange reading as well is that signal reading with both battery terminals is 6v!!
Would this be a short on the ecu cable or is it a corrupted ECU? Also today I had tough hesitation in the morning while the engine was cold, after warm up it was normal! Is this related or its idle sensor?! ( Plugs and their cables are new)...
Golf IV / Jetta IV :: VW 1.6 SR (AKL Engine) Rough Running / High Fuel Consumption
Regarding my problem (outline below):
>> Went for a refueling stop, and thereafter proceeded onto the highway
>> Approx. 500m into the drive onto the highway the car started jerking and running rough with an initial puff of smoke (none thereafter)
>> Immediately after this initial jerking/shuddering there was a significant increase in fuel consumption i.e. from a familiar 8.2L/100km to 18L/100km in the cruise
>> We continued driving not knowing what it was (I suspected a spark plug may have stopped working)
>> Pulled up at the gas station to observe what went wrong inside the engine bay - no signs of any leaks, fuel sprays, etc. but only that the engine was shaking
>> I checked the rear of the car while the car was idling and observed a pulsating sound...some light smoke and a fuel-rich egg-like smell
>> Asked around and I was led to think the catalytic converter was ruined, so the next day I had the catalytic converter cut out
>> After removing the catalytic converter the problem persisted...although the engine operated with slightly less flow resistance
Attempt at diagnosing the problem
>> My wife called in a technician from BMW at Canal Walk to come have a look and what errors were flagged
>> The tech ran the diagnostic and no fault codes were indicated, except a few short circuit faults due to my incorrectly placing -ve on +ve when I tried to charge my cars battery with jumper cables
>> He proceeded to ask if we changed the spark plugs, I said yes. He then looked at the oil on the intake manifold and said there could be a torn valve on the intake manifold and that air that is not measured by the air mass flow sensor is entering the engine, which is causing the car to rev hunt (this problem of rev hunting has been with us for a while). The engine also shuts down uncommanded at stops and sometimes between shifting gears with the subsequent loss of power steering (very dangerous!!)
>> We also had the O2 sensor replaced a month before this occurence

Went to Cape City VW in Cape Town and the part number for that orange thing/diaphragm is 06A 198 205A 'Repair kit for valve'. Is this significant? The car sounds as strange at idle...as if has noisy valves. I can upload (if there is an option) a sound clip of how the car sounds if this assists.

Ford - Freestyle :: 2006 - Oil Consumption Is Ridiculously High?
My stepmother has a 2006 Ford Freestyle AWD with a 3.0L Volvo engine. It seems to be consuming a great deal of oil. (Definitely not leaking it.) But not on a regular basis.... Within a couple weeks of changing the oil this time, it has consumed nearly 2 quarts! Other times it hardly uses any. This has been going on for a couple years now. She has taken it to the dealership numerous times and they cannot seem to find the issue. It doesn't have a "burnt" smell when I pull the dipstick either. The mileage is low as she hardly drives the car. (Under 80,000 miles) I've looked online and can't seem to find this problem elsewhere.
View 3 RepliesGen 3 Prius (Audio/Electronics) :: Power Consumption Of USB Device Too High?
If I plug in my IPhone 4 using the USB cord plugged into the receptacle under the armrest (how you plug in to run the wonderful entune ) the pictured notification intermittently and quite often pops up. This stops my phone from charging and is annoying as it makes the dinging sound every time and I have to unplug / re plug it in and hope that it starts back up charging. Does the little lightning bolt that signifies that the phone is charging must be on for entune to work, or does it only have to be plugged in??
Now I do recall somewhere hearing that the USB is not the optimal way to charge a phone, and I'll admit when it does work it charges real slow. Thing is that's the only way to run Entune and there is only one plug on the cell phone? I could charge the phone via a cigarette lighter charger but then I can't use entune!
Passat (B5) :: 1.8T AWT Fuel Consumption And Power Loss On 2nd And 3rd Gear
I had idle travelling problem wich I solved changing AIT sensor. At the same time I cleaned MAF and TB with air sensor cleaner. Now my problem is cold start and driving 2nd and 3rd gear. Instantaneuous fuel consumption will go 20l to 50l driving 2nd and 3rd gear and if I stop values lowers like 20l...16l...10l... and finally on idle it stays in 0.8l/s. Average consumpion has increased 1l to 2l/100km.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - High Oil Consumption - Low Boost
Alrighty let me see if I can get everything. 01 6speed 450hp at rear wheels. Comp 910 valve springs, valve seals, 238-80% injectors, full RR, 38r turbo, napa air filter, Hydra with Gearhead tunes, 5"exhaust, 280k about 100k on rebuild. All mods done 40k ago. Now I have a horrible up pipe leak I assume is causing the low boost #'s I have to do another clutch so up pipes will be fixed when tranny is out this week. But I'm using 1-2 gallons of oil every 3k or so. I smell burning oil when I get out, mainly if I am getting on it then stop. I haven't pulled the fuel filter to see if its a injector o ring. (Tonight's project) but turbo sounds fine, I'm going check for shaft play tonight. What could be my loss of oil without it actually leaking on the ground?
View 14 RepliesSanta Fe (CM - 2007-12) :: Loss Of Power/ Increased Fuel Consumption
What's happening with my Santa Fe (3.5L AWD). In the past couple of weeks I'm seeing poorer fuel economy (about 15% worse) and the vehicle feels like it is down on power, especially in fifth gear. I mean, the vehicle works and some might not notice, but... There are no warning lights. Engine oil is slightly high (1/4 inch or less) and transmission oil appears to be correctly filled. Don't see leaks from this vehicle on the driveway.
I had an oil change about 3 weeks ago, at a Hyundai dealership, where I switched from regular to synthetic. I was told that no special procedure was required in making that switch, so none was done. About two weeks ago, the stereo system was dead one day. Would not turn on at all. In trying to troubleshoot I pulled the Audio and Radio fuses (there seemed to be three in the dash area), but they were fine and after I reinstalled them the radio worked again. Those are the only maintenance and other issues I've seen in months.
The vehicle has pretty new rear brakes and I don't feel unusual heat there. Could the switch over in oil types or electrical issue with the radio be related? I've done many hundreds of miles since both events.
Ford 6.0L Power Stroke Diesel :: Fuel Consumption At Idle
As most of us probably do up in the colder regions, idle time likely increases to some degree. I do have and use the high idle mod unless it's a cold start and the truck does it on it's own during warm up.
I guess what I have always wondered is how much fuel does one actually use during idle? Reason I ask is it has not really hurt the mileage that much at this point from what I have been seeing. Sure it does go down but it's not really bad.
How long do posters here let a truck sit and idle, for instance when running an errand or making a stop?
10 minutes?
20?
Longer?
We all know during cold weather the big over the road trucks will sit for an hour or longer when drivers stop, and most let them run all night if at a truck or rest stop.......granted the circumstances are different.
Ford 6.7L Power Stroke Diesel :: Fuel Consumption At Idle During Arctic Operation
Did a little experiment today. I was in Fairbanks this week and today it was between -35* and -40*F. Quite frankly I was too lazy to park my truck behind the building and plug in, so I just left it running.
2015 F350 KR, 63k miles. Fully deleted and tuned with a PPE Ez-Lynk. I've been running the stock tune because mileage seems about the same between all of them and when it's winter with ice and snow, you don't go anywhere fast. 5W40 synthetic oil with 7300 miles on it and 220ish hours. Change engine oil soon light has been on for the last 200 miles and 20 hours.
I have the BD Diesel high idle kit with the rotating switch to adjust the idle level. Fuel consumption was monitored using the truck computer, which I have found to be very accurate on a consistent basis. Computer was reset at the start of each trial.
Trial 1: RPMS set at 1250 via high idle kit. Truck idled for 6 hours, 10 minutes. Fuel consumption was indicated at 5.2 gallons, or roughly .85 gallons per hour. Engine oil temp was about 185*F (remember ambient temp is -40). I was pretty surprised at how much fuel it used.
Trial 2: Back from lunch at Taco King. Figured the truck itself is pretty smart, so if the engine got too cold, it would probably boost the RPMS on it's own. Turned high idle off. Idled for 4 hours 15 minutes. Fuel consumption was 1.8 gallons, or roughly .43 gallons per hour. Engine oil temp was 150*F. Much more reasonable consumption.
.85 gallons an hour is pretty expensive but .43 gallons an hour is much, much more economical.
The biggest difference, besides fuel consumption, was engine oil temperature with a 35* difference. Is 150*F a safe, sustainable oil temperature for these engines to idle at without causing excessive wear?
Prius (Gen 2) Fuel :: 2005 - Fuel Consumption Increase After Service And New Brakes
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.
