#108 of 138 My best... by krony May 09, 2008 (2:44 pm)
Did a little test on my '06 Limited 5-speed...seeing how much I could squeeze out of it in-town. 190 miles & 6.737 US gal for 28.2mpg (computer showed 25.8mpg for the tank).   Lots of work though...light on the throttle and little to no brakes...lots of coasting when coming to stoplights. Makes me think enough to give you a headache...thinking I'll stick to the normal 24mpg.
#109 of 138 hard to fill by colteagle May 28, 2008 (12:48 pm)
I have a 2008 PT Touring and I find it is hard to completely fill the gas tank everytime. Sometimes if you wiggle and shake the car and wait awhile you can get almost 3 more gallons in the tank. This means that from tank full to tank full your MPG goes up and down from 30 to 17. I think this is the reason people get such a wide range in reported gas millage.

Replying to: colteagle (May 28, 2008 12:48 pm) Just traded my 2002 Limited for a 2003 GT Turbo today. I'll have to see how it does on MPG compared to the "old" one...lol.    Ref the tank filling question. the tanks are a very standard size, and the manual says to shut off the fuel as soon as the auto off clicks. I always round it up to even money. The factory has told us salesmen that people shouldn't overfill the tank as it can lead to run off when the gas heats in the tank during warmer days, and run it out the overflow tube on the fill line. That might affect mileage. They also warn that due to it being a pressurized system, it can splatter out if someone opens the gas cap shortly after it has been over filled, creating a highly dangerous explosive/fire condition. Sounds logical. However, even if you fill it completely, everytime, the variation cannot be much between fill ups. I don't think that would be the culprit to the wide variations in MPG. I would bet it wouldn't make a 1/2 MPG difference from one to the next time.    I think there must be something else causing the vast differences. I know the cars are very sensitive to diffenrnces in driving styles, so accelerating harder over a part of one tank may affect mileage quite a bit.    Who knows! I just know I love driving a cool little "hot rod"! Willie D
#111 of 138 gas guzzler by lil_frita Jun 04, 2008 (9:45 am)
I inherited my 2002 PT from my stepfather last November, and I have to say it is as bad as an SUV or truck when it comes to mpg. I get at best 16 mpg. I've gotten as bad as 10! 10!! I spend most of my driving on the freeway, and there haven't been any problems before with the car. Is there anything anyone can suggest to make it a little bit better?   Right now I'm looking into trading it in or selling it myself.

Replying to: lil_frita (Jun 04, 2008 9:45 am) I don't know what is going on.Could it need a tuneup? My 2006 touring gets 20.5-21 city and 27-31 highway. I do not accelerate rapidly, etc. About filling up the tank past the auto shutoff. I saw on the news that it is harmful to the charcoal filter.

Replying to: lil_frita (Jun 04, 2008 9:45 am) Is there anything anyone can suggest to make it a little bit better?   You didn't mention how many miles it has or what regular maintenance was done on it before you took possession. My wife's aunt seems to think that all a car ever needs is gas and maybe an oil change every few years.   The previous suggestion of a tune-up is a good idea, if it hasn't had one lately or if you don't know the condition of the plugs, air filter, wires, etc. A can of a quality fuel injector cleaner in the tank might help (ask the auto parts guys). Pay attention to the recommended mixture ratio on the can and don't overdo it.   There's also a simple and free solution you might try first. Disconnect the negative battery cable and leave it off for at least an hour or more. After you reattach it start the car and let it idle for 2-3 minutes while the computer relearns the idle. After that, drive at varying speeds for the first hour or so.   The objective is to let the computer learn your driving habits and adjust accordingly. Your step-father may have driven it entirely differently for many years and now if you are driving mostly highway miles things could change by resetting the computer.

Replying to: lil_frita (Jun 04, 2008 9:45 am) Hello! I only got about 22 mpg, but when I sold these they all seemed to get MUCH better than yours is! I would suggest a check and replacement of the spark plugs and wires. You might have a vacumn leak or an O2 sensor going bad as well. Could be any of, or all of those things. Check your tire pressure carefully and keep them near the max for best mileage too. The PT is sensitive to throttle application as well. If you drive them hard they drop down pretty severe in MPG. My new 2003 I wrote about earlier had plugs and wires put on it, and new rear tires, and the initial check indicates around 30 MPG!! Blew me away! I'll have a better picture for reporting on the actual MPG after a 600 Mile round trip I'll be taking on June 11th. Good luck, let us know if plugs and wires help.

I've noticed that about the throttle applcation. Before, I got about 18-19 in the city.Now, I get in the 20-21 city miles.

Replying to: camshot2 (Jun 04, 2008 12:40 pm) I'm surprised at all the folks who have been getting below the EPA suggested mileage for the PT Cruiser. I purchased a new, Base Cruiser, about a month ago. Standard transmission, no A/C. I live in Northern Idaho and have put about 1300 miles on the car already. It is about 10 miles into the nearest town over rural roads with 6 to 7 stop signs/lights on the way. With about 10% of my driving on freeways, my overall average has been in excess of 30 MPG (checked using both the onboard computer and dividing gallons used into miles driven) for combined city and highway driving. I drive the speed limit and use the cruise control as much as possible. I am easy on the throttle during acceleration and try to anticipate stop signs by stopping without excess braking. The worst mileage I have gotten for a single trip was 25.5 MPG driving at 75 MPH on the Freeway into the wind. No wind freeway driving at 60 to 65 yields about 31 MPG. Don't know if I am just lucky, or if it is the way that I drive. All I know is that I am getting roughly the same overall mileage with this car as I did with the '99 Mazda 626 that I traded and having a lot more fun.   Hope this helps and good luck with yours.
