Hi XTS owners

Was just curious, hows the consupmtion so far for your XTS ?

I am scheduled to try a FWD XTS next week and was wondering about the fuel consumption

Thanks

For some reason I'm consistently averaging around 13.5 mpg

Right foot dependent; it will get EPA numbers if you use a little discretion. (maybe better if you're a hyper-miler).

Actual calculation or computer figure. Computers are typically about 10% positive.

What's your average? I am curious, as I have same engine re-tuned.

For comparison sake, our STS got 25mpg on freeway, 16mpg avg. Our Grand Cherokee Overland 25mpg on freeway, 12mpg avg, our Boxster 29mpg on freeway, 22mpg avg.

All typical, with A/C on.

So far, the ATS is giving me 19mpg avg, but I am still under 1,000 miles. I estimate 17mpg avg in the XTS with my driving style.

Seriously, did anyone buy a Caddy because of the great gas mileage? It gets reasonable mpg and it does it on regular fuel. My BMW's got reasonable mpg on premium fuel or diesel at about $0.50 more per gallon. I like my Caddy better for comfort, drive, and even mpg.

Good point Cap.

After 2800 miles, in town and highway, my XTS Luxury FWD is showing 22.7 mpg. I will be a very happy camper if this continues. My last DTS (07) never got over 19.5 and the XTS V-6 seems to do as well power-wise as the old V-8 in most of my driving situations. I am a little anxious about the new transmission-seems to not be able to make up its mind sometimes when slowing down. Anybody else?

After 500 miles in XTS Platinum AWD, I've been getting 13-14 mpg. No I didn't get it for mileage, but Cadillac states 17 city - 26 highway. You should get what they advertise. Ask Hundai/Kia

You are not seeing true average mileage yet. Measure it manually for now, or wait until you have another 500 miles, or more, on the car. Even so, city/highway mileage are measured in a peculiar way. City numbers are only a guide - your driving style, local surroundings, A/C usage, etc., can throw it way off.

Just finished the first 'road trip' with SilverFox, my XTS Platinum. It was a 594.5 mile trip which included highway driving, cruising in the mid 80s mph, city driving (in and around LA), etc. The actual calculated mpg was 25.1 overall. I anticipate it will get better once I have several thousand miles on her. Very pleased with the ride, power, handling and comfort. The car drew complements just about every place I stopped. :cool2:

XTS4 Platinum: Still getting 13-14 mpg. Mostly city type driving. My 2004 STS got 15-17. Expected better and again, Cadillac claims 17-26

Actual calculation or computer figure. Computers are typically about 10% positive.

I see this contention a lot and it puzzles me.

The computer knows exactly how much fuel you're using-- it has to, since it runs the injectors and sprays precisely metered bursts of fuel depending on driving conditions.

The computer also knows exactly how fast and far you're going since it runs the speedometer and odometer.

Filling up a car, by comparison, is an imprecise process. You can't see the fuel level and different pumps shut off at different times (I've found that hoses without the rubber sealing bellows give me a little more gas.

So I don't see why the computer readout would be optimistic...unless, of course, it's programmed that way, which I suppose it could be.

I use a nifty little program called Fuelly. www.fuelly.com.
I never partially fill the tank and have done 4 fill ups and 1113 miles.

24.1
23.5
24.7
22.7

All of my mileage is about 65% freeway and these number relect that. My best is 24.7 and avg. is 23.7
I am always on cruise on the freeway at approx 72mph, climate control on at 72 deg.

It tracks fuel prices, avg. price, cost/mile and other little things.

Good news is that it's free.

My point was that different pumps will shut off at different points in the fillup, so "filling your tank" at Pump A probably won't match "filling your tank" at Pump B.

My Cts gained 2-4 mpg on the hwy once the engine got about 4000 miles on it. Xts should be the same.

OK, just finished 700 mile trip, ave speed 61.7 mph( mostly insterstate) and best ave mpg was 21.7. I have never seen the kind of mileage described on the sticker 17-26 and definitely not the 29 mpg describe in earlier posts. XTS Platinum AWD (appx 3000 miles on car) is not living up to expectations. "04 Seville with NorthStar was much better ( consistently 24-26+ on highway).

Recent trip 400 miles. 3 passengers and luggage. Mostly hi way miles, avg mpg was 22.9. My XTS is AWD and currently has approx. 4000 miles.

On the roundtrip to my brother's in CT, most of it on I-81, I consistently got ~2 mpg better going North, in two different cars and even in winter, when I thought the wind was against me. Must have something to do with the shape of the hills.

It does look like my LLT V6 STS gets worse mileage than my DeVille did, but it's so hard to drive it slow and easy. Either you get bogged down in 6th at 1200 rpm or you want to accelerate and downshift and watch the instantaneous mpg drop to single digits. Is the XTS like that?
