  • I drive the same DI AWD. My commute is 12 miles one way and I only averaged 16 to 17 mpg on a tank. I now have over 16k on the car. I did not see better mileage until I hit about 15k. I am now getting about 18 to 19 mpg. The one thing I did notice is I get better mileage without using the AC. I talked to another guy today who has the same car. He started out just getting around 14 and is now averaging 17. He had not one complaint about his car....he, like me just loves it to darned much to say anything bad. My only complaint is the dealer requires anywhere from 2 to 6 times to fix a warranty repair. :shades: From sunny Palm Springs.....
  • I have not seen or heard what CTS, STS and DTS represent.
    I came up with what seems reasonable:
    1. CTS, Cadillac Touring Sedan
    2. STS, Sport Touring Sedan
    3. DTS, Deville Touring Sedan
    Has anyone seen information from General Motors?
  • I dunno if there is any official explanation. But working backwards, the DTS evolved from the DeVille so that makes sense. The STS evolved from the Seville so I suspect that the Seville is what the first letter stood for. To my knowledge, the CTS was designated as that from the start as the replacement for the Catera, but I don't think GM wants to remember that name, so maybe it just stands for CTS.
  • Well, perhaps I have less reason to be concerned. I have a 2009 CTS DI RWD. I'm nearing the 1000 mile mark and I've been averaging 15.5MPG. My main commute is 21 miles each way with a fair amount of congested highway each way. The thing that concerns me is that, driving pretty much the same way as the 96 Accord I replaced, I'm getting much worse mileage than I expected. WIth the Accord, I'd average around 25MPG. The CTS averages 10MPG worse, but only runs about 4MPG worse on the ratings.

    I love the car, but filling up about every 270 miles is pretty painful.

    not to add to your frustration..but if you have to be concerned about filling up the $40K cadillac over a honda.....then perhaps you should have stayed with Honda....was the honda a 4-banger..manual or auto?

    21 miles in congested traffic..highway or otherwise will dramatically impact MPG,,you will not see high 20's in the CTS until an extended highway road trip....in northern va....im averaging 22-23 around town with stop and go....and 28-30 on the highway....over 100 miles steady highway driving at 70 plus..09 with 4k on it none DI engine

    Plus I bet the Caddy weighs a whole lot more than the Honda too. From cracker box to limo you have to give up something. :P

    was that CTS stands for Compact Touring Sedan (compact only by Cadillac standards), but I'm curious too if there's a real answer out there.

    "C" class Touring Sedan. The CTS was developed to be Cadillac's compeditor for the Mercedes "C" class.

    That's a common mistake. They were following an alphabetical pattern only.

    They had the huge DTS, the Middle Sized CTS, and the BTS(which never was sold in the U.S.) The current CTS was meant to compete with the base 5 series at a *much* lower price.

    "They had the huge DTS, the Middle Sized CTS, and the BTS. . ."

    So, given that and GM's current "situation," there is surely an FTS somewhere in the mix in the not-too-distant future.
  • I love this car...but really....$20,000 more for the additional 252 HP......

    I got 304 HP now....she's plenty fast I just dont see the value VS the added expense. BUT...Great car I agree!

    Now that it is freezing in NY , I noticed that my cold tire pressure was 30-31 , so I added air till 35 . However , during driving , when the tires get warm , the pressure goes up to 37-39 . Should I keep it under inflated , so that it is normal when hot , or keep it inflated at 35 , and ignore the fact that the pressure rises to 37-39 when hot .

    Always check tires cold and set the pressure to 35psi. Do not underinflate, the manufacturer has allowed for heat inflation.

    From the owners manual:
    How to Check
    Use a good quality pocket-type gage to check
    tire pressure. You cannot tell if your tires are
    properly inflated simply by looking at them.
    Radial tires may look properly inflated even when
    they are underinflated. Check the tire’s inflation
    pressure when the tires are cold. Cold means your
    vehicle has been sitting for at least three hours
    or driven no more than 1 mile (1.6 km).
    Remove the valve cap from the tire valve stem.
    Press the tire gage firmly onto the valve to
    get a pressure measurement. If the cold tire
    inflation pressure matches the recommended
    pressure on the Tire and Loading Information
    label, no further adjustment is necessary. If the
    inflation pressure is low, add air until you reach
    the recommended amount.
    If you overfill the tire, release air by pushing on
    the metal stem in the center of the tire valve.
    Re-check the tire pressure with the tire gage.
    Be sure to put the valve caps back on the valve
    stems. They help prevent leaks by keeping out
    dirt and moisture.

    Thanks a lot for the info . My concern was that when the weather was warm the cold tire pressure was fine , but the pressure got lower because of the outside temperature getting cold . I guess that during warm days when my cold tire is at 35 , the pressure also increases a lot too while I am driving . Thanks again .

    I am shopping for a used CTS DI. Is there any way to tell a CTS is non-DI or DI? There are a lot of used CTS advertised in our local market but I am not sure if the salesman really know wether a particular car is DI or not. I would like to have an independent way of verifying the engine..
  • There will be a small badge on the left side of the trunk lid that says "3.6 direct injection".

    I've been wanting to install a set of bracketless all-season wipers(i.e. Bosch Icons or Valeo) on my 08 CTS, but can't seem to find a web site that sells them for my car. Can the CTS only use the factory wipers?

    I have experienced this also. That is a perfect description of the noise that I hear around 40 mph. I just bought an 09 CTS V6 DI and it's perfect except for this odd noise/vibration around 40 mph. If I shift into the sport mode and downshift, it goes away. At first I thought maybe it was a tire balance issue, but I am now thinking it must be a drive shaft issue. I will continue to monitor Cadillac bulletins to see if anything comes out. Until then I guess I'll have to go slow or fast. ;)
