Ford Crown Victoria/Mercury Grand Marquis: Real World MPG

    Canadian's use imperial gallons which are a little bigger than US gallons. So you have to compensate for that. Both the window sticker and the computer must be using imperial gallons to calculate mileage.

    Mileage decreases as altitude increases because at higher levels you get less air per gulp. The engin then compensates for the thinner air by gulping more fuel. Sorry to hear you missed the Jasper area. It would have been worth your arriving later in Banff. ;)

    Mileage Update:
    I just got back from a 800 mile round trip that was 90% highway driving between 65-75mph. I got 26mpg for the trip.
    The car now has just over 3kmi on it.

    Keep away from under the hood. Don't touch a thing. Keep the hood closed. You've got a good thing going for you. ;)
  • On websites talking about New York replacing their taxis with greener ones, they say their Crown Victorias/Grand Marquis were getting 10 mpg. How could this be so low?

    Idleing for long periods will contribute to low MPG.
  • Also have to mention that the media never gets their facts straight, as they are cheerleaders of the "latest and greatest" mindset. They are not accountants.
  • I read conflicting information online about the Grand Marquis' gas mileage. Some claim better than Mercury's website says and others give it worse. Guess I'll have to wait and see.
  • I monitor several webpages on behalf of Ford and I hope you don't mind my posting here. Echoing other comments taxis in general and NYC taxis in particular are subject to extreme driving conditions including excessive idling time, stop & go driving and 20 hours of daily air conditioning in the summer. Even with good maintenance, the mpg will be lower than what the average consumer can get in their Crown Victoria or Grand Marquis. With that said most reports state CV taxis achieve 12-14 mpg.

    Sites like Edmunds.com are good sources for getting mpg numbers from a variety of owners and driving situations. Just remember you're most likely to see only the highest/best or lowest/worst mpg posted or reported online. As they say, your mileage will vary. We appreciate your purchase.

    Because you monitor for Ford I hope you will hear my comments below.

    That Ford continues to install Crown Victoria engines in Town Cars is not providing a Town Car level engine for the TC. The price of the Town Car screams for a more powerful and distinctive engine. At least provide a "Power Option" engine of 5.4 L enabling the TC to not be plagued with the same engine as the CV. The Power Option should be a $250 extra cost item. The 239 hp 4.6L is just too enemic when traversing the Rockies and Cascade ranges both here and in Canada. :sick:

    Your Panthers have been since 1998. When will we be given the option of a NEW car with NEW styling that still seats Six? :cry:

    Presently, your 2008 TC drives me towards the Jaguar XJ8L and we've owned three TC's since 1980. ;)
  • Ford should advertise the Grand Marquis. I have never seen an ad, either tv or print, for this car. As one who is buying a new 2008 and has it on order, I think Ford might sell more if they'd advertise them. I'm not an old person (48), read Consumer Reports and other publications, read websites, go to the car show and investigate all the cars, and despite all the negative things I read about the Grand Marquis about it being dated, etc., I'm buying one, because I feel this car is much more comfortable and roomy than any other for the price and I love traditional large American sedans. If I feel this way, then others must too.

    Thanks for the feedback. I'll forward your comments to the correct departments. There are a lot of factors behind design, engineering and marketing decisions including customer input. As I can't monitor every site all the time, I'd like to recommend another way you can let Ford know what's on your mind. Please visit ford.com and give us your feedback. The comments posted there get forwarded to the proper department for evaluation. Again, I do appreciate the time you've taken to reply to my post.
  • I believe that my gas mileage has suffered as a result of cold weather.
    I don't know how much less it is.
    On average, my car gets 17 or 18 mpg.

    Does anyone know what other factors contribute to lower fuel economy on this type of car? :confuse:

    Tires lose air pressure when it is cold. Pump them up to 35 psi.

    Over time, the Air filter gets dirty, check it and maybe replace it.

    Unnecessary idling wastes fuel as does Jack rabbit starts. Drive smoothly with no quick moves.

    Try the next level quality of fuel such as Mid grade, 88 or 89 octane.
  • Ford's customer service is lacking, I'm afraid. I've telephoned them and emailed them, and they don't answer my questions that I wanted answers to. I asked the dealer, but they don't know the answers. Here's the questions:

    1. For my new 2008 Mercury Grand Marquis LS, for the audiophile system I have, where are all 8 speakers located, along with the subwoofer? I can only find 4 areas with speaker grills (1 in each of the front doors and 2 behind the rear seat). Do each of these areas have 2 speakers next to each other?

    2. Why doesn't the steering wheel lock? Every other car I've ever owned had a steering wheel that locked.

    3. What were the manufacturing problems that prevented them from being able to give me the laminated side glass option I was supposed to get with my order, but did not?

    4. Why did it take 4 months for me to get my car after it was ordered, instead of the 2-3 month wait the dealer said it would take?

    Although I'm not happy with Ford customer service, I'm very pleased with my car. I've had it 2 weeks now and feel I've made the right choice.

    I just purchased a 2007 GM LS, and so far have averaged 19-20 mpg on combined city/hwy (about 50/50 mix). I was wondering if anyone has tried E85 in their GM?

    I haven't had the opportunity yet, becuase most of the E85 dealers near me only charge 5-10% less for E85 than gas, and I understand that E85 gets at least 15% less mpg. There are some other stations further out where E85 is about 15-20% less than straight gas, but I dont want to make a special trip out that way, but will give it a shot next time I'm out that way, just wondering if anyone has any data on this????

    I wouldn't put any E85 in any ICE including the lawnmower. :sick:
  • E85 is another liberal lie. A big scam that doesn't help anyone.

    Youn mention the handling package on your GM. In 2008, I purchased a 2002 GM LS. What Vin numbers are associated with the handling package?
  • euphoniumeuphonium Great Northwest, West of the Cascades.Posts: 3,305
    Oversize tires, dual exhaust, & the 239 hp engine would indicate a car with the "handling package". I don't know that the VIN would indicate the package any more than the VIN would indicate what audio system is incorporated.

    If you air up the tires to 35 lbs and then feel every crack in the pavement as the car corners like a locomotive, you probably have the Handling Package.
