Chevrolet - Tahoe :: 2004 - Gas Mileage Dropping On V8
I have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?
View 4 RepliesPrius (Gen 3) :: 2010 Mileage Is Dropping Than Usual
I just bought a 2010 salvage Prius. I have another 2010 I have been driving for 3 years so I am pretty used to the mileage I can expect under different conditions.
When the car is totally warm and I measure the mileage for 15 miles or so I get normal readings of mpg. But with a lot of 2-3 mile trips during the week I am getting about 10mpg less than usual compared to my other 2010.
Subaru - Outback :: 2015 - Gas Mileage Has Been Steadily Dropping
Gas mileage as stated by Suburu for the 2015 Outback (2.5 engine) is 25-33 with a combined of 28. Mine has never attained that and it has been steadily dropping. Now it is displays as 19 mpg. It is new and has just under 500 miles on it, and I read that the break-in is 1000 miles. That being said, shouldn't I be seeing better MPG than that?
BTW - I am hoping that I am just not being fair (to the car and to Suburu) and that I'll be up in the advertised MPG's soon after I hit 1000 miles.

View 7 RepliesGrand Prix :: 2002 Pontiac Speed Dropping On Highway - Temperature Really High On Gauge
One day, I was on the highway and my Pontiac's speed started dropping. I looked at the temperature gauge, and the temperature was really high. I flushed the coolant system, and changed the gasket. Also the mechanic said that the oil might be leaking after they changed the oil. I paid like $700 for something that has nothing to do with the problem (I paid for a spark plug, ignition wires, fuel filter, and an oxygen sensor). After they changed the oil, oil started leaking all over my driveway, which didn't happen before. It also looked like coolant was leaking out. None of this happened before I got my oil changed with these guys.
After I changed the gasket, the car was running smoothly. But today, the same thing happened again, and I don't know if it's the thermostat, or water pump, or oil leaking, or coolant. The mechanic always suggests to fix something that doesn't have to do with the problem. I don't have much money on hand, so I need to only fix what has to do with the temperature rising, and I need my car to run.
C/K :: 1999 5.7L Gas Mileage 23 Mpg On Highway
'99 5.7L extended cab 4x4. What kind of gas mileage is realistic for this truck? Guy told me he'd gotten 23mpg on the highway, that sounds unrealistic to me...
View 7 RepliesPrius (Gen 2) Fuel :: Gas Mileage 48 Mpg Around Town And 55 Mpg On Highway
My 2006 Prius used to get GREAt gas mileage - 48 mpg around town and 55 mpg on the highway. Recently and all of a sudden, my mpg's have taken a nose dive. I now get 35 mpg! When I'm on the highway, I barely get 44 mpg. I took it to the dealer and they couldn't find anything so they are insistant that it's my driving, oxygenated gas and/or my tire pressure (even though they didn't check the tire pressure).
My driving hasn't changed; my friend with a 2004 Prius buys her gas at the same station and she's still getting ~48 mpg so I'm thinking it's not the gas; and I am OCD about keeping my pressure constant. (I own a compressor and check the tire pressure A LOT.) I drive 5 miles to work - about 15-20 minutes - on relatively level paved roads. About 2-3 times a week I travel longer distances at highway speed. I wash and wax the car fairly regularly to reduce wind drag. I have noticed periodically when I'm coasting downhill, my mpg's are less than 20 mpg so I'm thinking something's terribly wrong.
Golf V R32 :: Gas Mileage Started Going Up On Mixed Highway And City Driving
I'm at 9600 miles now and i noticed my gas mileage started going up---the last two fill ups with the same daily route:
23.9 mpg! in mixed highway and city driving! average speed 25-35mph for a typical trip!
Now, granted I've been driving gently...but that brought me to another exiting tid bit:
If I don't want to drive spiritedly (because I'm on the phone--hands free of course---or because I'm thinking about work)....this car is so smooth and comfortable....
I had a dodge charger before and that boat wasn't as comfortable nor as agile---by a ton! And then today....it's raining in fort worth....but that's no problem...no spinning tires at lights....amazingly better traction with AWD compared with my 1.8t!
Prius (Gen 3) Fuel :: 2013 Persona Getting Low Mileage On Highway Drive At Roughly 65 Mph
I just purchased a new 2013 Prius Persona. I am used to the Prius line as I previously had a 2005 Prius. I have only had the car 4 days but I noticed that the gas mileage is less than what it was on my old Prius. I mostly drive highway at roughly 65 mph. My driving style is the same as it was with the old car. I am getting less than 40 mpg; with my old car I would get roughly 43-45 mpg. Will this improve as the car breaks in or could something be wrong with the car?
View 15 RepliesPrius (2010-12) Fuel :: Temps Have Been Dropping, MPG Dropping As Well
Grill blocked today for the first time and have a couple questions.
Temps have been dropping more these last 3-4 days and have noticed my MPG dropping as well so I thought I'd try grill blocking.
Tempts have been and will be high 30s-low 40s in the morning and upper 50s to mid 60s for the high.
At first I just wedged the pipe insulation and drove one trip. I didn't feel comfortable that it would hold for the long haul so I added zip ties.
I used two pieces of pipe insulation 1/2 inch copper / 3/8 inch iron. Up close it looks like 2/3 or 3/4 of the grill is covered.
My two questions:
For fWT, at what temperature should it not exceed?
At what outside temperature should I remove the pipe insulation? In the Phoenix area, temperatures rise in March and sometimes we will have a short period of warmer than normal temps in February. I just want to make sure I do not cause overheating.
Passat (B5) :: 2004 - Power Cut Out When Cruising At About 65 Mph On Highway
So I've owned my 04 Passat for almost 3-4 months now, I have a 1.8T 4Motion w/ 5speed, and love it. It will certainly be nice in the winter time with the snow and cold here in North Dakota.
I was driving on one of the state highways, and was cruising at about 65mph, when the power cut out, and giving gas didn't do anything and I eventually came to a stop. I let the car sit for a minute, tried starting and could tell that the engine was trying to turn over but wouldn't. This has happened before with my jetta, and its always been because of water in the fuel lines during a heavy rain, so I had my roommate come give me some more gas to see if we could just run the water out of the system since it had been raining pretty heavily here lately. Still no joy on getting started, occasionally the engine would turn over, RPM's would get up to about 1100-1200, and then instead of stabilizing at idle, the engine would just cut out again right away.
Got a tow from my insurance company to a local auto service shop who took a look at it and got a code saying the speed sensor wasn't working. They allegedly took it apart last night and fixed the speed sensor, had a loose wire, but it still won't start up. They've narrowed it down to the crankshaft sensor, or the entire ECU module being shot. I'll know by tomorrow if the crankshaft sensor is in fact the case.
If it isn't the crankshaft sensor, then is it definitely an issue with the ECU? Would it be worth to get an ECU pre-chipped(APR seems to be the way to go), and have that installed instead of a stock unit? Is it even possible to get a chip from these guys that comes already chipped, or would I need to get a new ECU first and then get it modded.
Passat (B5) :: Temp Gauge Dropping Low At 120 - 130?
I recently purchased an 03 GLX wagon 4 motion from a dealer as is. It had 84,000 on it when I got it and needed a timing belt. The work was performed by a VW dealer and all has been well until today. I was on the highway, had been working the car pretty well for about an hour and i noticed that the temp gauge which is at 190 religiously is now dropped down as low as 120- 130.
I continued to drive, thinking maybe just a bad sensor/gauge considering I had no check engine light yet. I still have good heat but when I got home I noticed that the coolant reservoir was bubbling pretty fierce. Couldn't tell if it was boiling or if it was compression coming back in from perhaps a head gasket failure.
Passat (B6) :: Transmission Dropping Down To 5th Or Sometimes Even 4th At Cruising Speeds
I have a 2010 Passat 2.0T with 42k miles. Since it rolled over 38k on the odometer, I have been having a problem with the tranny dropping down to 5th, sometimes even 4th, while at cruising speeds (80-85 mph...Live in Texas). I notice this mostly on long drives (Ft Worth to San Antonio). The problem usually occurs while in Drive when I punch it to pass. Although, this is not always the case; sometimes it will drop down by simply letting off the accelerator or pushing the brake.
When this happens, I have to manually shift it back into 6th and its a crap shoot if it stays there when I put it back into Drive. This last trip I drove 90% manually because it would not stay in 6th in Drive. After calling the dealer and them telling me that it was probably a cruise problem, I turned off the cruise and drove without it with the same results. I bought this car used with 19k miles; Is the transmission covered under warranty or are there any recalls on this?
Passat (B5) :: Throttle Lag / When Shift Through First Two Gears RPM Not Dropping Immediately
I've just bought a 2002 Passat, v6 5 speed manual with 119,000 km on it. When I shift through the first two gears the rpm are not dropping immediately... about a 1 second lag. I haven't had a clear answer about what it is I have called two dealerships and two independent mechanics except. They say that it could be a variety of things that might be wrong with the throttle body.
View 6 RepliesPrius (2004-09) :: MPG Has Been Dropping Steadily
My 2007 Prius (72k miles) has been dropping in MPG steadily for the last 6-8 months. Where we would get a strong 42 mpg, we are now experiencing 34-36 mpg. After a 400 mile trip to the coast, we just experienced a 34 mpg average. 1 year ago, we would have seen 42-45 mpg on the same trip.
I had the dealership check it out, only to tell me the computer says nothing was wrong. This is the 2nd time I've voiced this concern about the car in 12 months. They told me to replace the tires. We did. No change.
I checked the 12v battery through system check on the display screen (method I found on this website). It was showing 12.4v for an unloaded battery. When i put a load on it, it dropped to 11.7v. Once I had it charging, it raised to 14.0v.
Prius (2004-09) Fuel :: MPG Dropping Around 42 Instead Of 49?
=this is my first summer to own a prius, and I noticed this last week that my fuel economy seems to be slipping. I am averaging around 42 MPG instead of my usual 49. Only reason this worries me is I've noticed the car is charging the battery a LOT, and it's not uncommon to have my MPG drop down to the low 20's on a flat road if I am lightly accelerating.
