Default New owner & mpg question...

Howdy everyone!

I'm the proud new owner of a 2007 PT cruiser. Only 35,000km (20,000 miles). Looks and rides like new and only $10k.

So far, the best mileage I've been able to get out of it is about 10.5l/100km (23mpg) This is 90% highway driving. Are these cars just poor highway commuters?

My 2009 Ford Escape got better mileage on the same routes. Considering that the Escape is an SUV and had a V6 engine, I'd expect the PT to get way better mileage.

One other question... There is an odd wind noise I'm hearing above 15km/h (10 mph). It sounds kind of like a slurping noise. It's not affected by engine speed or the heating fan so I'm sure that it's just wind noise. Any idea where to start looking? I don't see anything out of place or anything caught on the car.

Thanks!!!

23 mpg is about right...mine gets 24-26 depending on where I buy gas. The city mileage is worse...some report as low as the low teens, but most are in the high teens. I cannot report on this as I do mostly highway as well.

Mine is also a 2007 with just a few more miles (28,000), bought in December for just over $10k.

I have an 06 Base with a manual transmission. I've had it for almost 6 mos now. (50k miles and paid $5000 with new tires and excellent shape).

I drive in the city as well as on the highway. I have found no rhyme or reason to my mileage differences. Same driving patterns and habits and my mileage will vary between 22-27.

I hear your frustration with the mileage. My wife's Chrysler Sebring 08 has a 2.4 in it and she averages 29-30mpg. One tank she even got 35mpg.

Sorry, can't help with the wind noise.

Welcome to the Forums.
Make sure your tires are inflated - I go 2-3 PSI above the door sticker #.
I also use synthetic oil - better for engine and helps a wee bit.
A K&N air filter will also help a bit.
And, if you haven't done so, change the plugs and wires - gap at 0,040 - the stock wires don't last.

I've gotten as high as 29mpg parkway with my auto. You have to drive really nice to get good mpg. The PT really needed another gear on the auto.

Like quicksilverdon said you can tweak out some extra but the PT will never be great it's more of an SUV crossover than an economy car.

Nobody has addressed your slurping noise so I'll try. I know when I'm driving and have the stereo on if one window is partially open or the sun/moon roof is open the air coming in tends to vibrate the music. Make sure all windows are closed tightly and see if the noise (slurping) goes away.

Also put your HVAC dial on "recirculate" and not on outside air and see if that helps. You could have a leaf or debris stuck in the incoming vent.

I've had my '08 for exactly a week. It's an automatic I put Pilot gas in it this wee. It has no ethanol in it. I got 24.4 today on my 46 mile ride to work, with the air on. That ride includes a couple miles of back roads, two traffic lights and the rest highway. I also found that if you don't hit the max air conditioning button for the entire ride it males a difference.

To all: don't depend to much with the readout of the dash. The best way is to fill up and figure your mileage with paper and pencil or do like a number of us have and enter it by using fuelly.com, it then keeps track of all of your averages.

I have gotten as much as 30+ a couple of times at 55 MPH and looking at my signature you can see what I have done to our PT. A lot of it is for our pleasure.

I wish they had Pilot around here!

I speculate another reason the pt doesn't get good or as good of mileage similar cars in its catagory can get is the lack of chrysler enthusiasm and lack of some modern technology, like valve and cam timing adjustments.
plus it is over 3,000 pounds.....thats a big car....some of that you can blame on federal agencies requiring more protection which is a good thing but everyting comes at a cost. and some of that you can blame on society requiring more and more standard equipment.

there are guys who claim to regularly get 30+ miles per gallon, but like many I have only acheived that lofty height a couple of times.

there are lots of websites out there with dedicated people learning, teaching, and trying new ways to get better gas mileage....some ways are plain dangerous, but they do get better gas mileage....and some ways are simple and easy to achieve with out being reckless.
its been said countless times all over that...
"adjusting the nutt behind the steering wheel is the best bet for gas mileage"
lucky for car makers they add in that line at the bottom of the EPA ratings "your mileage may vary" or we all could just sue like crazy and never have to pay for gas again ROFL.
