View 11 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.

Ford :: 2007 - Poor Gas Mileage?
I have a 07 Ford F150, 4.2 liter V-6, that the city gas mileage has fallen from 17 to 12.5, highway from 22 to 16.5, in that last year or so. Two garages have ran a test on the computer and can find nothing wrong.

I recently bought a 1983 Ford Ranger Diesel pickup truck (2.2L Mazda engine, manual transmission). The dealer said to expect a little above 30 mpg on fuel mileage but the two fill-ups I've done show an average fuel mileage of 22 mpg. About half of these are highway miles.
I thought diesels are supposed to have good mileage. Is this typical for my year and model truck? Is there any way to increase the mileage? I just replaced the air and fuel filters and also changed the oil and oil filters.
Ford F-150 (2009-2014) :: Premium Unleaded Gas Increase Fuel Mileage?
I was wondering if one would experience increased fuel mileage &/or power with the 5.0 by using unleaded premium gas, and if so, how much? I know this is true w/ the 6.2L in the F-250, and was wondering if the same applied to the 5.0?

View 2 RepliesFord 6.0L Power Stroke Diesel :: 2005 - Poor Fuel Mileage?
I just bought my first diesel truck back in November. It's a 2005 F-250 with the 6.0L and the 5 spd torq-shift automatic tranny. Last weekend I drove the truck to South Carolina, about a 600 mile round trip from where I live. On the trip the truck only got 13 mpg! I wasn't towing a trailer and the truck was empty except for me and my suitcase. It's not loaded up with mods or anything, it's completely stock power wise.
I'm extremely disappointing, especially since a friend of mine has a 2006 F-250 identical to mine and he gets up to 21 mpg on his. What can be done to improve my mileage? I'm not a lead-footed driver, and the trip was done with almost all interstate and highway driving, very little driving on back roads or stop and go. If this is the best the truck will get, I'm going to sell it and buy a F-150!
Ford Excursion :: Low Power - Poor Mileage - Transmission Delay Going Into Reverse
For the past two years I've noticed a decrease in fuel economy and recently noticed that the truck did not "feel" as if it had the same power especially when towing. Checking all the usual suspects with the engine turned up nothing and the transmission wasn't showing any signs of problems other than an occasional delay going into reverse. But it had been doing that for years and so I just ignored it.
Recently the torque converter started acting up and had some other occasional shifting delays and so decided to put the vehicle in the shop. The electronics all checked out and so a HD rebuild kit was ordered. The truck was finished this morning. Just barely pressing the accelerator makes the vehicle instantly start forward with noticeable zip. Plenty of power at all speeds, the engine now feels like new.
I suspect the main culprit was the torque converter. It wasn't enough to notice in excessive rpms nor heat (at least according to the instrument gauge) but the loss is noticeable in hindsight when compared to the repaired system. Over the next few weeks I'll get some mileage numbers and will know for sure whether I've found the sole cause of my power problems but I am sure that I've made a fairly large step in solving them.
Ford F-150 (2009-2014) :: 2010 Lariat Losing Fuel Mileage Suddenly
I have a 2010 F150 Supercrew 5.4 Lariat that just turned 100,000 miles that is losing fuel mileage all of a sudden... Over the years I'd get 16-17 mpg city and 18/19 highway(best I ever got was 20 mpg on a trip from New Orleans to Houston with cruise set on 65 all the way and no stops) always checked- tank vs miles, not on dash, and with every tank... I've changed all the plugs recently, did the BG Induction Service and BG Transmission service, K&N filter cleaned and recharged, about to do the MAP sensor cleaning also... I've dropped to 15-15.5 miles for the last two tanks...
Truck runs fine but maybe it's just me seems slightly sluggish when driving and accelerate to speed up quickly. Idles fine etc... I've just ordered a scanner for the computer, not that I have any codes YET...but I'm just trying to figure this out to get back to my normal mileage... Again no codes but what about the 02 sensors, they've never been changed... any other tweaks you knowledgeable folks can think of? Also ran Seafoam through the last two tanks... I pull a trailer from time to time... but not for a while... can the transmission get stuck in a lower setting since I'm told they "adjust" and need a few hundred miles to adjust back to non hauling?
Ford Super Duty (1999-2016) :: 2005 V10 - Poor Throttle Response And Mileage
My friend has a F250. He was getting terrible mileage and the mechanic he took it to replaced the intake gaskets. After that the mileage went to 12 and he was happy. Now its down to 6-8, just highway. It seems to me the throttle response is terrible compared to my dad's 01 V10. And it sounds terrible. Exhaust manifolds aren't leaking that I see.
I've got AE and have hooked it up, but I'm really not very familiar with these trucks. I don't get any codes that would relate to anything. Had one trans sensor code but that was about it. Key on engine running test didn't say anything.
Prius Plug-in 2012-15 :: 2014 - Mileage From 45 - 46 Normal?
Brand new 2014 Prius Plug in. I am getting about 45 mpg on a 14-mile all-city trip and 46 mpg on a 30-mile mixed hwy/city trip. The mpg numbers are from the information display when the car were turned off.
Is that normal? I thought it's supposed to be about 50 mpg. Btw, ECO mode was enabled.
Ford 7.3L Power Stroke (1999-2003) :: Intermittent Throttle Response And Poor Fuel Mileage
I have read many different threads regarding the TPS sensor on the pedal and EBPV deletes on the E99 7.3L Powerstrokes. I am trying to troubleshoot some issues with my E99 7.3L. Usually on cool mornings and after not being started for awhile the truck will seem to be stuck in an Idle. This is an intermittent problem that doesn't always happen.
I cleaned the connections to the Tps and the IVS sensor and put them back in. No luck. On another note I am also seeing a reduction in fuel mileage and power like the truck is being restricted. I don't know if these symptoms are related or possibly their own issues. I am troubleshooting and possibly thinking it is the EBPV system that isn't working correctly. Considering doing an EBPV delete with a NON-EBPV Pedestal and Flange.

Honda - Accord :: 2011 - Poor Gas Mileage?
I have a 2011 honda accord with 15,000 miles on it that Has only gotten 20mpg since it was new. It is supposed to get 23mpg city and 34mpg highway. I figured I was the tires but since fixing the leaking valve stems it is still only 20mpg. I asked the dealer about it several times during oil changes after I first bought it and they claimed to look into it and find nothing wrong. Is there anything I can do to fix this or would it be covered under new yorks lemon laws?
View 19 RepliesPrius (Gen 2) :: Poor Gas Mileage And Transmission Not Going To High Gear?
My 08 has been getting poor mileage for the past 3 weeks or so ..... I tried a "push the power button and trip reset shift to reverse to eliminate the backup beep" mod and it did not work. However I find now that I cannot get my MPG average above 42. When I tried the mod the odometer went immediately to all bars and then the bar indicators went out one by one until the regular odometer reading came on .... I'm wondering if doing that also set the car into another "mode" where the tranny will not shift to a higher gear???? So symptoms are constant engine running when cruising to a stop and after 20-30 seconds the motor will shut off .... and while driving on the highway the engine will pick up at least 1000 - 1500 rpms just by adjusting the accelerator a smudge .....

Alero :: 2000 2.4 - Skipping And Rough Idle - Poor Gas Mileage
I have a 2000 Alero w/ 2.4 103,000 miles auto. I have been trying to fix a problem for about 3 months. It all started one night when i got stuck in my backyard in about a foot if mud. I thought i could drive it out, but when the wheels would spin and traction control would limit the rpms. After getting out the car would skip every now and then going up an incline at highway speeds in 4th gear (drive) then it would skip while idling. I could get it to run smooth if i hit the pedal and made it shift to 3rd. I drive this car daily and the problem has got worse slowly. Now its hard to crank and when it does there is a small amount of white smoke with strong gas smell while the motor spudders for about 10 secs.
It will finally "clear" up and still misfire every few secs or just cut off. Gas mileage is terrible between 15-18mpg. The engine light and trac off light has only been on twice. Both times the code was for random misfire of multiple cylinders. I have put plugs, boots (wires), distributor, 2 fuel processor regulator, seafoam, all octanes of gas, pulled injectors (looked ok a little dirty but still could be one) and I have ordered ignition control module. Its getting hard to drive and even harder to sell. It has just started the white smoke and gas smell and i think its that's the pressure regulator, but the skipping and rough idle....
Honda - Accord :: 1998 - Vapor Leak And Poor Gas Mileage
I have a 1998 Honda Accord, automatic with 179,000 miles. The malfunction indicator light came on so I had the car smoked and found that it needed a purge valve. I replaced the purge valve and smoked the car again which indicated the car still has a vapor leak and the malfunction light stayed on. The only place visible smoke is coming from is from the fuel filler neck (place where fuel or gas is put into the car) when the gas cap is off. Where the leak may be? My car is also getting horrible gas mileage. I was going to replace the fuel filter but I heard it was in the gas tank, is this right and is it replaceable? Would replacing the gas cap work for either the vapor leak or gas mileage?
