2006 Mustang

[Natalya]

Sold in 2016!!



2006 V6 Automatic

Not a combination you see every day... The Mustang was my DD for most of its life until I bought the Insight last year and parked it. But it's revived right now and so I gotta do some stuff to improve the fuel economy.

Actually, I've already done a few things:
- All lights are LED except headlights and fog lights. Every other indicator or signal or whatever, everything is LED down to the map lights.
- Aluminum drive shaft (20 pounds lighter than stock driveshaft)
- Exhaust system is from a GT and has no backpressure
- Tires at 46 psi
- Spoiler from GT500 looks like it's probably more aerodynamic than the stock one

Planned mods:
- Do something about the front bumper, it's totally not aerodynamic
- Underbelly panels!!

Not sure what else, I'm open to suggestions.

need to get a scangauge. It will help you adjust the "nut behind the wheel". Probably 40-50% of all increase in mpg can be traced back to us!
See the first link in my signature.

also I have a pretty good description oh installing a bellypan with lots of pics in the third link.

I got an underdrive pulley on my mustang and it gave me a noticeable improvement in power and mpg.

Not to be rude, but we primarily focus on results that's can be quantified. We enjoy our ABA testing, and hard numbers. Of course on an engine change, it isn't easy to ABA, but getting a baseline fuel range in an area and doing more testing in that spot with later modifications is also a fair way to keep track*. Not meant in a mean or rude way, just letting you know that we (as a forum) put more stock in a scientific method based result than generalizations.


*Also noting other factors, such as wind, temperature, traffic, so on.

I wasn't able to do any proper testing but I did get a 22.6 mpg tank before the pulley and a 26.4 mpg tank after the pulley. Most of the improvement was probably from more highway driving on the second tank.

Did a 40km trip last night, no traffic. Huge elevation changes though, driving down then up the Niagara Escarpment. The highest point was near the beginning at 845 feet above sea level, the lowest point was at about 246 above sea level, and then later I drove back up to 725 feet near the end of the trip.

I reset the trip economy indicator on the car at the start and it said 8.6 l/100km average at the end of the trip which is 27.35 mpg. I was pretty surprised I got that good a result even with the elevation changes. Mustang Dave mentioned in another thread keeping RPM below 2500. For most of the trip it was around 2000. The incline is not as high as the decline, but it's a lot longer of a distance, the first third was the decline, the second 2 thirds were mostly incline with a bit of flat here and there at the end.

I have noticed if I'm on a flat and I can go slowly, at about 42MPH the car gets mid-high 30's with the RPM less than 2000, I think around 1750. The elevations here really don't permit that kind of travel, but it's nice when a trip allows for that.

Nice! Both of your car join Team Mustang, as well

Edit: I'm usually not much of a fan of the bodystyle for your generation, but I just saw the main picture, and wow! Sharp looking car!

In my AB testing (I won't take the time nor undo the mod to do ABA testing) I gained close to 1 MPG with an under-drive crankshaft pulley on my Mustang. I have the fuel log numbers to show it. Before I installed the under-drive pulley, I had a few 32+ MPG fill-ups, but those were all "one in a row". After I installed the under-drive pulley, I logged 8 consecutive fill-ups over 32 MPG (until Winter fuel and temperatures hit).

To Natalya:
As mcrews said, get a ScanGauge or an UltraGauge. It will help you "adjust the nut behind the steering wheel".

As mentioned in the hypermiling tips, minimize use of the brakes. Your brakes are very efficient at converting gasoline to heat and brake dust.

Wow. I agree. For my least favourite Mustang body, it looks darn sharp. What I don't think anyone has said as far as tips go, is to keep your speeds down. Aero is not and never was a Mustang strong suit. The 4.0l V6 most probably will respond well to keeping acceleration at a moderate pace, too. ScanGauge or UltraGauge is a must!

274 km since last fill up, 23.1 litres used according to the car's computer. Does anyone know if the litres used is accurate on these Mustangs?
