I know I am for real, I don't think I have ever seen below 45mpg. 90% of my driving is on the highway, at the speed limit. High speed kills... your mpg's, low temps kill your mpg's, stop-n-go kills your mpg's. I also run my tire pressure at 38psi. I am the only one who fills my car, I do find that my mileage is still improving with 60K miles on the car. In the winter my snow tires kill 3-4 mpg's. All my fillups are posted in my fuelly account.

I'm for real, but I'll clarify that my best tanks have been in the low 50s and are more commonly in the mid-high 40s. My lifetime average (23k miles) is 46.7MPG based on fuel receipts, and that's with me driving ~74 highway miles every day. I usually do >50MPG on my long highway commute, but shorter trips result in MUCH lower mileage. If you check fuelly you'll see there are plenty of people with mileage like yours, so don't despair. Also, check that you're looking at the right average consumption--if you hit the OK button you'll toggle between average over past 9,999 miles or during the current drive. If you're only getting up to 40 MPG on a long highway drive, that may be the longer average (which actually varies a lot more on the MFI than is realistic if actually looking back over 10k miles).

Thanks for all the comments. The only fuel consumption indications I watch are the ODO and the gals at the fuel pump, then divide. In 21k miles I've calc'ed and recorded all but 2 tanks. Sweet spot 36-38. One thing that has bothered is some ignition miss in the first 10 minutes partic when moisture is high, and temp is cool. It's really subtle....can barely feel it, mainly at lower RPMs with no throttle pressure. It's made me wonder whether its impacting mileage. Dealer said it might be turbo warming up. Anyone felt that miss?

To throw in my .02, I have seen mileage numbers in the mid-upper 40s at speeds toward the 80ish range on several long distance trips. Best ever was 60mpg with considerable effort, but traveling around the speed limit it isn't uncommon to get around 50 mpg. I can't comment on city driving as I rarely do it, almost all of my driving is highway with light traffic.

Thumbs up

With a little extra attention to conditions you can see better mpgs city than highway......

If you watch traffic conditions not to over accelerate just to have to slam on brakes.

If you get into the highest gear possible sooner than later, at speeds above 35-38 mph when terrain allows(~1,100 rpms or higher if no acceleration is required).

Light throttle, give time to accelerate to desired speed. Especially when the engine is cold which is when they use the most fuel. Skip gears not needed and get into high gear & stay there as much as conditions allow....

Don't push the thing up the hill, allow your speed to slow slightly while going up a grade.

Along with using N on down grades as much as conditions allow as fuel if you have terrain of a few hills you can see much higher mpgs city than during sustained higher highway speeds. Many times you can use a pulse of energy then let gravity get you up to the speed limit(up to your desired speed) saving fuel.



I have ~38 years of records in all kinds of gasoline and diesel powered offerings to prove that the above allows maximum mpgs to be seen on city/urban tanks......

______________________________________________

I had to get a full size chevy pickup a recently and using the above techniques I was able to push mpgs up to 17 to around 20 running around the urban area. Talking to the previous owner the way he drove it over the last decade or so it would have been 11-13 mpgs maximum if he clocked those miles the way he drove.......

What really sucks is we just got the car back from a month at the bodyshop two weeks ago, after it was backed into by an F-150 while sitting in a friend's driveway.
A little less than a year and we were finally able to use our Passat for the reason it was purchased. We drove from Connecticut down the Winston-Salem, NC area. According to the computer we averaged 48 MPG. That was using the cruise as much as traffic permitted, but also hauling the mail whenever possible.

Tim,
My Mpg's are real as are I suspect the others reporting good numbers. I can get 50+ on some trips, but not a whole tank. This has been said before but I'll break it down as I see it.

Short hops of less than 20miles will make it hard to get great mileage numbers. The car needs to be warmed up good. And you need the really good numbers you get later in the drive to compensate for the low numbers when the engine, and bearings are cold. My commute is 55miles and I don't get up to the highest mpg numbers until the end of the trip.

High speed and hard acceleration obviously hurts. But a quick accel up to legal speeds are ok.

I warm up real gentle for first 5 miles. But I always hit high Revs at least once every drive.

I coast a lot. It's a game, I look ahead and know whether I can keep speed or need to coast because I have to slow down. Like not using the brakes as much as possible. It also is great for safety keeping yourself far out ahead of yourself. I'll also coast down any hill I see. This car coasts so well. I laugh cause I know suv's and other cars are using gas and I'm on their tail and I'm coasting in neutral. Look, I don't drive fast anymore so I use other games to keep me interested.

I run tires at 40psi. The work fine, stop fine, turn fine. It's not a sports car.

Know that cold weather kills the mpg. It just does as does the crappier winter fuel blend.

I skip shift all the time. Up thru 3rd and into 6th when getting on interstates. Try it.

I slow down a bit up steep long hills.

I'm not in a hurry anymore and I drive the speed limits to +5. It's not worth it anymore. I don't want a ticket and it costs more to drive fast.

Again, short trips hurt Mpg's. If I need to run errands in town, I do it after my commute when engine is still warm. I still get great mileage in town then because the car is a peak operating temps.

Nailed it!

Funny, I could have posted this, except for the skip shifting. This is a strategy I will employ in the future to see if it helps. Conversely, we had some weather that was very cold, 5* one morning and I ended up with my first tank UNDER 50 MPG in months.

Just did western nc -> Outer banks, some city driving (~140 miles) -> somewhere back past Raleigh

Many drives in ~40F

Fill up came in at 46.5 MPG

Lots of 75MPH in there

Make that trip usually twice a year. We live in WNC and vacay in OBX frequently. Fill the Passat before the trip, drove down and drive all week. Usually fill up coming off the island (most times 45 to 47 mpg) and use about 1/2 tank coming home. Those flat coastal roads at 50-55 mph work wonders on mpg.

Pretty much sums up my strategy as well, though I will engine brake on downhills as long as I can keep up my speed. The engine is nothing more than an air pump at that point and helps cool the engine a bit, plus you aren't using any fuel at all.

Skip shifting is standard operating procedure in a manual. I do it all the time. 3rd gear up to 4k shift into 6th and your at 65mph. Perfect for merging onto the highway, engine warm of course.

Tell me!

My GPS kept screaming at me to get on the main road going between Kitty Hawk & KDH and I kept ignoring it. Too much traffic & stop lights. Speed limit might be 45/50 but you lose it with a couple red lights.

Took Dare each time (the one by the beach) 35MPH flat and almost no stopping. Fifth gear cruise control.

Was getting 56MPG on those trips by the lie-o-meter on the dash.
