I recently changed my stock '06 Passat to the optional 17" wheels & tires..
Before the switch I would get about 28mpg on the highway, but now I'm getting 25 no matter how much I lay off the throttle.. I know they're heavier, wider tires.
I have a 2011 Camry LE with about 13,000 miles on it. I just replaced my tires with Bridgestone Turanza EL400 225/65/16 and now my mileage have drastically decreased, I used to get about 400 miles per tank driving strictly city, but now I'm lucky if I can actually reach 300 miles driving under the same condition (non aggressive city driving). Does increasing the width of the tires actually make this big of a difference in mileage?
View 14 RepliesI used to get really good mileage on my 12.5 mile commute, if I didn't reach 50 miles per gallon, I considered it a poor commute. But over the last several hundred miles, I have only averaged about 45 miles per gallon - sometimes I'm not even reaching 40 mpg. I checked my tires, they are fine. I also notice that the gasoline engine is running a lot. I'll be at a stop sign, and the battery is nearly full, but the gas engine is running.
View 19 RepliesIn the past year or so mileage on my Honda Fit (08) has decreased at least 100 miles per tank full. Changed spark plugs, put in additive, changed air filter. Tires ok. I have 120,000 miles on it...
View 10 RepliesHad my 2002 passat in for service to get my turbo replaced... wastegate had begun to fail and was causing a horrible clicking noise, decreased power, etc. Brand new turbo makes the car like a rocket and I love it. However, I am noticing what seems to be different behavior in this turbo compared to when I first bought the car. As I get the car up to mid 3000s on the tachometer, the turbo is nice and kicked in, but begins to waver...I hear the whine noise sort of going up and down and I see the tachometer twitching, going up and down slightly to moderately.
I am not changing how much I am depressing the accelerator so it seems to be just doing this on its own. The car was serviced by really excellent guys local to me who specialize in VW and Porsche performance. I am worried that something is already screwy with the turbo, or maybe this is how things are supposed to be. The car is functioning great otherwise...no check engine indicators or any of that sort of thing and the turbo sounds great but I am concerned that this odd fluctuation behavior with no direct cause from the driver is a problem.
A full tank for me runs about 450 miles ... 80% highway and 20% city roads. How come I am only getting 450/18 i.e., = 25 (with the ac on at times thought.. but I think it is hosing for me.
View 23 RepliesIn the last 2 weeks I get 60MPG (indicated) with ease on my 22 mile round trip all city work commute. The commute is very predictable with the same speeds and driving technique and similar light pattern.
The thing is, the most part of the summer I had to work hard to get upper 50's on the same commute.
No, I don't use AC as the temps are mild enough to drive with windows down in early morning and evening.
There are 2 variables: the ambient temp went down to low 80's rather than high 80's before.
I have a 2012 prius c with 72k miles. When i bought the car, it took a while for the fuel economy to increase. i drive 100 miles a day at 85mph and topped out at 52mpg. pretty damn good, if you ask me. im all interstate with very little city driving.
2 years later, its time to get new tires and ever since i changed them, my fuel economy has decreased to 45mpg.
My 07 Santa Fe 3.3 has had a 10% drop in mileage. When put the accelerator to the floor it takes forever to speed up. I feel like I have a 100 Hp engine.
View 6 RepliesMy V6 4Motion Passat has a CEL for an N80 valve... tried cleaning, didn't do anything. But its only getting 400-430 kms to the tank, even for winter that's pretty bad for 95% highway driving.
Could that cause bad fuel mileage?
I have a 1998 Honda Accord Coupe with a 2.3L straight 4 with a 5 speed manual. Last night when I was driving home the car was idling at around 200 RPM when the engine was warm. And then this morning it started fine, ran fine, but as the engine temperature increased the idle decreased, as it should. But even when it wasn't fully at the proper temp it was idling at 500 RPM. When it warmed up to the proper temp it was idling at 150, yes 150. It was touching the 0 RPM line, but it didn't stall. It has had problems in the past with initial low idling, like when you disengage the clutch, but never constantly idling so low. Keep in mind that the idling hasn't progressively gotten lower over time. The problem just arose last night. Also, it accelerates fine, and the check engine light isn't on. What is most likely the cause?
View 4 RepliesI have an '06 Subaru Forester (4 cyl, automatic) with about 97,000 miles on it. For the past 5 years I've had the car, it's been getting roughly 26-28 mpg on average. Within the past 3-4 months, though, the fuel economy has dramatically decreased. Now, I'm lucky if I get 21 mpg. (I used to be able to get almost 350 miles per tank, and now if I make it to 275 I'm jumping for joy!)
I took my car to the shop for the 90K service, and they didn't change the fuel filter as a part of that service. (They did replace the coolant, replace oil & filter, replace spark plugs, replace differential fluid front & rear, replace brake fluid, replace auto transaxle fluid, and then they did a bunch of inspections on belts, hoses, brakes, etc.)
I took the car back to the shop after this service so they could change the fuel filter, and they told me that because of the type of fuel filter I have, it should last the lifetime of the car. This sounded a little fishy to me, so is this true?
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.
View 6 RepliesAt 30,000 and change I had new tires and they did RVU 17D1/07 Crankcase Breather Valve Replacement recall. Ever since then I have notice a decrease in my MPG.
I was getting around 32 MPG (mostly Highway driving) or about 540 miles on a tank. Now I think i am LUCKY to get 28 or about 480.
Could it be the tires? Or is it something with this recall. I went from the Stock Michenlins to Cooper CS4 Touring. I just think 4 MPG would be alot from a tire change.
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.
While driving my 2006 Sonata yesterday I noticed a tapping noise that increased and decreased with speed. Not really loud, but audible. I looked and really didn't see anything. However, I looked earlier a little closer and noticed my left front wheel has a rubber looking belt, hose (unsure) laying across the inside part of wheel, closer to what I assume is caliper.
View 15 RepliesHas to replace the ball joints on b6. Mines got 64k on it and I am getting this vibration after i got my new wheels like 8 months ago. Two very well respected shops said nothing was wrong but there def is. When I slow down from 60 ish my wheel jerks back and forth. Its frustrating. I've tried new tires, alignment, balancing. When I first got the wheels the ride was smooth then it got shaky after 500 ish miles. It only happens after 45 miles an hour. Replacing all the rubber suspension parts is the last thing i can think of at this point.
View 5 RepliesI was just curious and bored this morning. So I wanted to ask you all what mileage did you replace your timing belt at?
View 24 RepliesI have noticed over the past few months that my gas mileage is dropping (from about 29 to 24) on the highway and I seem to have lost some power. I know the car is getting older, but where do you think I can get some of it back? The plugs are only 20K old and the air filter is new.
It is a 2004 1.8t with 109k on it.
The Problem(s):
[1]My car burns about 4 qt's of oil every 5,000 miles. I am constantly battling to keep the dipstick properly soaked.
[2]I bought the vehicle 8 months ago, at the time I was getting about 28 mpg cty 34-36hwy. Now I get about 21 or 22 mpg cty and lucky to get 25hwy . I know it's winter but should I be seeing this kind of a loss? I am not using the heat THAT often, or atleast not often enough to cause such a decline in mpg.
[3]The first thing I did when I bought the car was get an oil change. I took it to a non VW dealer and requested synthetic, the IDIOT monkey's did not grant my request they put their bulk trash in my car and 3 days later the oil was two qts low and darker than coal. I immediately took it to a smaller shop who changed the filter and put Syntec in. What I want too know is should I be using a different oil? Could the monkeys mistake be responsible for the current oil consumption?
How do I know if my turbo gasket(s) are bad? Anything else I could do to improve economy?I use 93octane(w/o ethanol) My oil is Syntec 5W-30.
I recently picked up some Samarkands for my 3.6 4motion Passat which originally had the 17s on it. Since swapping, I first had a little wobbling issue which was mostly resolved with a balancing of the wheels. Now the only thing remaining is this sound of rubbing going on up front. It's pretty prominent at lower parking lot speeds since my ears can catch the sounds of the rotation. Being that they're factory wheels, from another Passat originally, I assumed they would bolt right up with no issue. They're ET44 18x8.5. Am I missing something here? Do I need spacers or something. If its anything involving an alignment, that would be awesome because I'm gonna need one after I lower the car when I get back from my trip.
