    How to improve mpg in a PT

    I have a 2006 PT Cruiser. It's got 19000kms on it. It's a turbo. I am getting about 18-20mpg. This seems awfull to me. Is there anything I can do to impove this. I was thinking a cold air intake. I don't want more power, just better mpg. Will that help and will it affect my warantee.
    If what I don't know can't hurt me; I'm indestructable!

    Stay out of the boost and your mpg will improve.

    It's hard to stay out of the boost when you know it's there. My last sportbike topped out at around 310kph. I found it hard to do the posted speed limit.

    Pin open the wastegate so it doesn't spool up.

    Big complaint of turbo owners is the bad mileage, and factory ECU's go quite rich to protect the motor when in boost condition.

    You could go the high-dollar route and get an electronic boost controller, so you can in-cab set it to zero boost for daily commuting, but turn the boost on when you wanna have fun (and know you're burning fuel doing it).

    Keep in mind also that you've got pretty poopy aerodynamics in that thing.

    Hmm I dunno if you'd wanna turn the boost off with a mbc... cai might help a bit.

    My srt-4 gets shit milage too, but you didnt buy the pt gt for gas milage... right? The only honest way to improve your milage is to just take it easy on the gas like they said, keep the guage to the left and you'll get good milage. How many km's you get to a tank in that thing anyway? My srt-4 takes like $40.00 and I get around 400km's with fairly aggressive driving habits, got it up over 600km's going 110 to new york and back stopping in niagra falls.

    if you wanna get goofy, you could lower it, get air diffusers top and bottom, unrestrict your exhaust- get a 3" downpipe and maybe exhaust all the way back. could buy lighter rims, try not carrying anything in the car... install a lip on your front bumper... smaller tires?

    Cost about $50 to fill and I get 430 km to a tank. Sounds like I'm just gonna have to adjust my driving habits. Not the answer I wanted to hear but thanks everyone for the interest.

    Before the PT I had a Golf TDI. $45=1050kms. The PT is quite an adjustment.

    UPDATE= I just finished my second tank since original post. The first tank I did not use the turbo at all. I kept the rpm's below 3000 and took off really gently And used the cruise all the time. I got 440km's. The second tank, I drove aggresively and used the turbo almost all the time. I got 430km's. Makes sense.

    first of all are u using high test???? higher compression requires better quality fuel Try the shell High test.......I use on my Jetta 1.8T turbo gas and I get almost 30 k more per tank thats all I use in my Dubb now

    Chrysler says I'm sposed to use 87 octane. Since 93 is 10% more expensive, I would have to get 44km/tank more just to break even.

    Hmmmm true...but I would double check on that they have 2 turbo versions though the 180 hp touring version and the the 230 hp GT version which I believe requires high test....but I may be wrong....

    The GT is the High Output The touring is not.

    I have the turbo '05 convertible with a K&N Typhoon intake system and I average abot 420km/tank. That is a mix of Highway/city. More Highway but my top is ALWAYS down as I am sure that comes into play on aerodynamics and fuel consumption.

    Turbo does not = good gas mileage. Then again I used to own a JEEP!

    - 06 XK V-8...parts on order
    - 08 JK Sahara Unlimted...Lifted w/MTZ's (sold)
    - 94 YJ...Lifted w/BFG's. (sold)

    I have the middle (180HP) turbo that calls for 87 octain. I have tried 92 and it gets better mpg but if you figure it out on paper with the higher price, it comes out the same. I guess I was just spoiled with my Golf TDI.

    Easiest way to improve your mileage is to install a 2 inch exhaust valve lifter spring from a Ford 302.

    The upgrade is simple, use a clean spring and self tapping screw and secure it to the floorboard directly under the accelerator pedal.
    You never truly know your limits until you exceed them....

    Funny you mentioned that UJ. I just finished that exact experiment. '00 Olds Alero, 2.4 automatic. Fill tank, from "Low Fuel" light, at 1.03 was $45.00. I got 440km to "Low Fuel" light. Refilled with Premium, $1.15L ($50 to fill), got 525km.

    Cheap fuel: 43L = 440km, or ~10.23L per 100km. 10.2¢ per kilometer
    Good stuff: 44L = 525km, or ~ 8.39L per 100km. 9.6¢ per kilometer

    I've ALWAYS wanted to try that, and now I know. It's actually cheaper to run more expensive fuel IF you stay out of the throttle. I do not drive aggressively in the car.
