So I'm not really fuel mileage depenant. However, my work does pay for my fuel bill. So in an effort to chip in I figured I'd start helping too.

So what have I found out.. Stablilitrac sucks fuel! This week I've been driving around with it off. My average has been prior 17mpg in the city. Now I'm looking at 22mpg which is bit better then the lowly 17mpg I get with my lead foot.

So has anyone else try'd this yet? I know its a pain to open the glove box and turn it off but give it a try.

I don't see how that's going to save gas...

If you are driving "spiritedly" enough to engage stabilitrack, your mileage is going to suck anyway lol.

I know.. I don't really buy into either. But in all honesty its difference, wether I'm the due cause or not. Tell me I'm nuts and lay off the throttle..:thepan:

I'm going to finish off the week and get the total..

Well, i should be getting 22mpg then, because i don't have stabilitrac on my model, but i'm not, I honestly think it's just placebo effect and your driving habits changing, but I don't know your driving habits so I can't say for sure

Save yourself some trouble and assign the traction control to one of your programable buttons through the DIC. I've got mine on the wheel for quick access if the mood arises.

That only turns off TCS, you have to hold the button for 30 seconds to disable Stabilitrac.

My stabilitrac ONLY engages when I try to turn a sharp corner and get on the gas too fast. When the yaw sensors pick up a faster than normal turn (i.e. spinning out of control), it takes over the throttle and brakes. It should never engage during normal driving.

With that said, I may try disabling it on my next road trip to see if there is something to this thread!

Amen brotha! And I can lay it down a bit easier now with the TonyA:D. Better watch it or else I'll have to start buying new tires every couple of months.

I'll have to give that I try, I know I have the TCS but I'm not sure about Stabilitrac.:hmm:

I have been witness to this as well. After turning off all methods of traction control, I tend to get better MPG. Tested this not too long ago and posted my results, and I do save a slight ammount with it off for some reason. I am wondering if it engages at all without displaying so on the DIC. I know that up to 20% braking power is applied, and fuel is cut, but I am wondering if it only tells you via DIC when the fuel is cut, and it is obvious that it is werking.

oh, here it is... " Is the fuel efficiency of my CTS reasonable?

this is what i average:

I have an '03 3.2L CTS 1SC, Sport Lux with 40000 miles, and this is what I average

With Stabiltrac and TCS on - normal driving ~23-24mpg
With Stabiltrac and TCS off - conservative driving ~27-30mpg
With Stabiltrac and TCS off + Sport Mode - aggressive driving ~17-20mpg

This debate was an ongoing thing there as well. :)

Please..anyone explain how this is possible!! Under normal driving none of these systems are functioning. Brakes or throttle are not affected:yup:
I'm with you Rob, that just dont make no sense! But I'll give it a try just for S & G.

I'm trying it on my way back to LA this afternoon from Ontario...I'm with Rob - I don't see how it is related but I "won't knock it till I try it"...Plus, since others have done it, what I got to lose??? so 30 secs on the TC button in the gove box turns of Stabilitrac, right?

This is an assumption! My take on these systems is that they are always monitoring the vehicle's system, and could be controling the car more then you can actually feel/perceive. Every time you step on the gas they could be doing something to prevent slippage, etc.

I hate to be the one to tell you, but this thread is right up there with UFO's and astrology. If Traction Control and Stabilitrac affected milage during normal driving it would not be on the car. Cadillac engineers have sweated bullets trying to improve milage to meet CAFE standards and avoid fleet gas guzzler penalties. Both of these features may have unwanted side effects but affecting gas milage is not one of them. If the brakes were applied by these systems under normal driving conditions enough to adversly affect milage, the brakes would be smoking when you got out of the car. The biggest single factor that affects milage is the drivers skill and habits. Back years ago when the Mobil Economy Run was a big deal it wasn't the same cars that won year after year it was the same drivers. Observe the Instantaneous MPG display on the DIC as you go down the road and you will quickly learn what steps to take to improve milage.

It appears my car is not equiped with stabilitrac...at least nothing happens (other than turning on/off traction control) when I hold the button. :hmm:

The big trouble with testimonial letters about UFO's, astrology, motor oil additives, and gas milage gadgets is that they are all written by the same people.
