[sccasper]

Hi I just bought a 2005 TDI Passat wagon with 2liter engine 17" wheels. I only get 23-24 city type driving and the most I got was 33.5mpg hwy driving is this norm or what am I doing wrong. Also AC is on as I`m in Florida summer climate....

mpg

How many miles on Passat? Remember the engine is larger than a Jetta or bug. How fast are you driving on interstate. 60 Mph or under gets you better MPG. Crank up those tires to 85% of maximum sidewall pressure.
When was air filter replaced and has snowscreen been cleaned? Alignment OK? I live in Florida and run AC all the time. Just a few things for you to check out.

Avg. 70-75mph on hwy. there are 22,000 miles on car. Just bought from VW dealer in Fort Myers and it was certified used car and they did all the services such as oil change they did the 20,000 mile service before it was sold which included fuel filter also. If you let go of steering wheel it will hold a straight line as long as the road stays straight and not sloped. The car looks and runs like it is off the showroom except mpg is under EPA rating of 28mpg city and 38mpg hwy! There is a computer generated display that reads your present mpg, avg mpg. miles to go to fill-up, etc. I`ve checked it out at fill-up and it is fairly accurate.
I`m wondering if I shpould tell the dealer or just hope it will change.
Also I`ve had a 98 jetta and with the same driving type I`ve been averaging 42-45mpg. I was hoping the Passat would do better than epa rating and surprised that it`s doing considerably worse.
Also what is a snow screen?

Sorry to say that something is not right. I also have an '05 Passat wagon and average 39MPG overall and 43 on the highwy at 70MPH.

These figures are from the optimistic onboard display. My tarvel is mixed highway and in town. Even the highway portion is often stop and go for long periods.

I'm not experienced enough to advise as to what is wrong, but something is for sure.

I do notice a hit of 3 to 4 MPG with the AC on.

Did the dealer/previous owner service/maintain the engine by using a 505.01 certified oil? If it is anything else, you mpg could take a hit and you are risking engine damage.

I know the vehicle was bought the same dealership I bought it from and all maintainance was performed there. He had it for exactly one year then traded for a Toureg states the salesman. I don`t know if the dealer uses that oil or not. I know they use Synthetic oil. I`ll have to ask them what brand/type they use. Is it reccomended to use a diesel fuel injector cleaner?

That mileage is actually good 23-27 is what I averaged in my Passat sedan in DC stop and go traffic.......
Highway was mid 30's and the faster you go the less you are going to get.
The best tank I ever got was 43 on a long trip with controlled speeds
I don't think there is anything wrong with the car........

You live in New Jersey, sccasper lives in Florida. This is the absolutely worst time of the year for his Passat's fuel economy. Then next winter, when you're complaining about low mileage with winterized fuel and slow engine warmups, he will be getting the best mileage of the year.

sccasper, you'll start to see better numbers in September, and October, and...

Seems spot on to what I'm experiencing. In city stop and go I get, on average, 9.2l/100km (25 MPG) and on long highway trips, have averaged 7.2l/100km (34 MPG). However, that's going 130-140 kph (80-90 mph ). I'm always tempted to try to see how far I could go by keeping it at 90-100 kph (55-60 mph) but I can't keep it that low . Maybe next trip I'll vent at fillup and slow down just to set the record straight.

If you're using the same driving style that got you 42 MPG in an A3 then you're probably not doing badly with the Passat. People who drive A3s for economy can get over 60 MPG, and over 50 is pretty common. The 17" wheels aren't helping, either.

That's pretty much the same mileage as I'm getting...with B99.9...

Seattle, WA, 21K miles on our '05 Passat sedan (17" wheels @ spec pressures) and we get 33 in the city (mixed, 75% city) and about 42 on roadtrips. Definatly noticed a 3-4mpg hit with the A/C and summer heat. BTW, heavy footed driving 80% of the time

Good Mileage

If you are averaging 39 overall that is very good. 43 MPG on the HWY is rare, especially at 70 MPH. Lucky for you with the higher MPG's.

My dad has a 2005 Passat GLS TDI wagon with 16" wheels. He just took a trip to Indiana and back (from Florida) and averaged 40 mpg going 70-75 mph. Drove from Leesburg, FL to Knoxville, TN on the way up there on one tank of fuel and still had a couple of gallons left in the tank.

i have almost 22k miles on my passat wagon (15" wheels). i get around 30-34 mpg's mixed (depending on the mix) and 36-40 mpg's hwy (depending on speed). i've taken a hit this month b/c of 100+ degree temps, but i'm still not doing too badly. i've tried to make myself slow down a bit to get better #'s, but boy is that hard! need more discipline.

however, i make sure to do some good 4000 rpm bonsai runs at least every 2-3 days to blow out the soot and keep the turbo humming.

back with better m`spg

My first post was disapointing at best. Since then, with no exageration, mu mpg has improved greater than epa statements. I`ve been driving at or slightly below speed limit. When I`m on I75 I drive 65mph not 70. At night if it`s not to horrible with humidity I drive with moonroof open and AC off. One test I did I found an avg. 3mpg increase with out AC.
Also I`m putting in Power Service
Diesel Kleen +Cetane Boost. 4oz. with every fillup. Doing this I`ve noticed a slight increase in power.. I`m averaging on 100% hwy, at or 5mph less than speedlimit, 43+/- one mpg. My avg. mix drive which is about 60% hwy and 40% city, comes in around 35-37 mpg. I`ve also noticed the cars computer generated avg. is almost right on the money with what I`m calculating after fillup.
I would like to know if the PS
Diesel Kleen +Cetane Boost has any damging effects on the 2005 PD motor? I have been using it off and on for a couple of years on my 98` Jetta TDI.

The only damage I've had on my 05 passat has been to fuel pumps getting destroyed running straight Biodiesel. Never had any problems running PS or B2 biodiesel as an additive. I don't know if it helps, but I doubt additive folks would stay in business if it hurt your system.
