Passat (B5) :: Ridiculous Oil Consumption - Gas Mileage Is Terrible
Feb 16, 2007
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 just bought a 2003 Tacoma 2.4l engine and it has terrible gas mileage.I haven't checked the numbers yet, drive for but it cost medrive for 2 hours. Where do I start looking? The air filter is clean, the tires have plenty of air.

So, I had a catback Magnaflow exhaust put on my Tiguan a while back and ever since then my mileage has gone from a steady 28 highway to 15!!! its a crazy loss in fuel, and I brought it to the shop and they said there is nothing they can find....
My first thoughts are that the turbo is under boosting because of the amount of carbon build up on the exhaust tips....

Why I am getting such terrible gas mileage? The truck refuses to move off of 12 mpg. I made a 500 mile trip half of it at 70 mph running 2100 rpm. And when I filled up I calculated out 11.3 mpg. After that fill up hopped on the interstate and was running around 85 @ 2600 rpm expecting my mileage to drop even lower. Then i was on two lane hwy again constantly passing people and it only dropped to 11.1 mpg. Now no matter how easy I drive or how hard I drive it will not move over 12 mpg. Whether the tank is 100% hwy or 50/50. Its a 5 spd manual 4x4 with no modifications running the 4.6 v8. I just swapped air filters to a K&N and still no change.

I have a 2009 Prius (purchased in March of '09) - working just fine - 58.6 mpg.
Each time that I have gone to purchase gas, I have not pushed the reset button on the Consumption screen as I have wanted to keep a running average for mpg. However, the miles driven count since the last refill automatically goes back to 0 (again on the Consumption Screen) and then starts a new count. This is useful as I know how many miles I have driven since the last refill. Today, however, I purchased fuel and the count did not revert to 0. Has a sensor been damaged? Is there anything I can or should do? I know I could press the Reset button but that would be a last resort.

So, there is a lot happening with the 3.6 hesitation fix lately. Haven't seen anything addressing the 2.0T hesitation. Mine has terrible throttle hesitation - have this problem with the 2.0T and/or looking for any fix? Love the feeling of making a lane change and almost getting smacked in the rear because of the lag ...

I used to get 55-58 MPG when my commute was 65 miles one way, 85% freeway. But these days I noticed that when AC runs hard and trips typically 16 miles, 40 MPH, mpg dropped to 42-45. That worried me a little bit.
Driving style: conservative. I start off normally, but I use N gear as soon as passing speed limit. (this factor alone should enhance mpg by 10 I guess. I used this technique on my 98' Lexus LS400, 4 Ltr V8 engine, once got 38 mpg on freeway, while the sticker says 18/25). This is the main reason I worry that something is wrong with my prius.
Typical range: 16 miles, all local.
Tire pressure: 40 psi
AC runs hard, outside temp 90 degrees, I set temp to 72 inside. (I guess this is the main reason for mpg drop, but I don't think it should drop that much)
I recently changed oil and trans oil.
My battery is a little bit weak, but no warning light. If I forget to turn off head lights, it needs jump in 10 minutes.
Mileage is 143K, 2004 model.
Water pump changed by Toyota free of charge.
Any clue? or it sounds normal and I don't need to worry about it?

I installed a brand new "A line" 007 last night. Now I have ridiculous boost surge (15psi then to 5psi, then holds 11 hard) I did a N75 race valve last year (ECS), so I have my doubts that it is the N75. So what gives? The car wasnt that bad with a blown stock DV compared to this. I have minor mods: CAI, exhaust, Forge TIP, APR stage 1.

Have a 2001 Passat V6 Manual 105000 Miles, Always used synthetic oil and changed every 5000 miles. After oil change, maybe around 3000-3500 miles oil level goes down to close to minimum. Roughly i'm burning little over a quart every 5000 Miles. Is this normal?? BTW there are no leaks/spots, no burning smell, no smoke coming out.

Alright so every 3-4 weeks I have to put about a quart of oil in the car. Its sometimes less, sometimes more. I HAD an oil leak from the passenger side valve tensioner gasket cover. I had the pcv system replaced and all new gaskets. No more oil leak. BUT, I still seem to be losing oil. I can't afford a quart or more every 3-4 weeks. I've looked all over the engine and underneath and haven't found any oil. If this persists, I might trade in and get a 24v VR6 GLI. I've had more small things go wrong with this car and its starting to piss me off. At least with a 24v I can get more power mods....

I just don't get what causes the Passat 1.8T to have worse fuel economy than expected considering its 0.27 drag coefficient, 3200lbs curb weight, and 4 cylinder 1.8t engine compared to a 3,500lbs 3.4 liter V6 0.31 cod Impala. I mean a new Ford Escape NON Hybrid SUV will get the fuel economy on the highway as a 1.8T Passat and that's sad considering that the Escape has the drag coefficient of a brick and the B5.5 Passats are among the 10 most aerodynamic cars ever sold in North America.

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.
These are the air mass readings when I drive 2nd and 3rd gear

We just past 1000 miles on our new 08 2.0T wagon and there is '0' oil consumption. The dipstick reads completely full. And...it is noticeably cleaner than our 06 2.0T after 1000 miles (after oil changes).

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.

My 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 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.

At 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.

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 was just curious and bored this morning. So I wanted to ask you all what mileage did you replace your timing belt at?

I 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.
