28 MPG? How?
Are any of you guys getting 28 MPG with your sixxers? The past four fillups I've averaged a whopping 19 MPG. Is it possible sometihng is interferring iwth my good gas mileage or is this about right? I don't think my driving habits are bad.. I shift aruond 4000 RPM and I always cruise in the lowest gear possible (for example at 55 MPH I shift directly from 3rd to 5th). What's wrong with my stang?

RE: 28 MPG? How?
Unless I'm going up a hill ... I shift around 2000 RPM or so .... During normal day to day driving I see no reason to ever touch 4 Grand on the tach .. My first tank averaged about 22.5 MPG .... The manual says the readings are not accurate until 2000 - 3000 miles ....

+1 on the shifting habits; 4000 is for racing, shift at 2000 and use cruise control when you can. I have the IUP and check mileage at crusing speeds (70 mph) on cruise control and see 30+ mpg. When I drive mellow I can get 22+ combined city/freeway. Bottom line is how you drive, if you drive mostly city with a lot of start and stop 19 mpg is probably about right with the way you shift.

RE: 28 MPG? How?
I drive my Mustang in my work, so I keep meticulous records for tax purposes. I have put 18,500 miles on my 06 since I bought it on 12/26/05, and have averaged 26.66 mpg overall. I don't have the Info center - and I don't really trust it to be accurate anyway - so I calculate my fuel mileage the old fashioned way: Miles driven / gallons used.
My worst tank so far has been 23.0, and my best was 29.6 (twice).
I also shift at around 2000 - 2500 rpm, I guess I probably 'get into it' a few times a week - running it up to 60 or 70 at WOT, shifting at 4500 or so.
Most of my driving is in the Portland, OR metro area, so it's 15 minutes of stoplight to stoplight, then 15 minutes on the freeway, then 15 more minutes of city driving - several times a day (I do on-site tech support). some rush hour stop & go, and very occasionally I get the opportunity to drive a full tank on the freeway.
Does that help any?

RE: 28 MPG? How?
You divide how many miles one tank gets by how many gallons your car holds right??
I think im only getting like 16.5 with the procharger set up but im going to keep watching it. I shift at 2500 - 3000 at the most. I got about 240 miles out of a whole tank. I used to get like 265 - 274 miles out of a whole tank of gas but not anymore lol. I don't think I ever averaged anything over 18.9 with my car and that was when it was NA. [:'(] Makes me think something is wrong??? I never even got into the 20's let alone 28 miles

RE: 28 MPG? How?
Not quite. That is only accurate assuming you run the tank dry. You divide the number of miles you drove since your last fillup by the number of gallons it takes to fill it back up. If you are really concerned about mileage, I found it interesting to set the IUP guage to Fuel Efficiency meter and try to keep it at peak efficiency. Basically, the rated 29 mpg highway mileage (for a manual) is what you get if you never put your foot down all the way!

Driving on short trips, i average around 19 or 20 miles per gallon. I have taken my Mustang on one business trip, around 500 miles on the interstate. Doing around 70 most of the trip, i did get 28.5 miles per gallon. Thats the most i have been able to squeeze out of a gallon to date.

RE: 28 MPG? How?
ummm lol. I consider that good gas mileage for shifting at 4k. Its simple. Shift before 2500rpm unless your passing or going up a hill. Whoever tautght you how to drive a stick didn't explain it well enough. The higher the rpm's the harder the engine is working and the more the engine is working the more fuel your engine will use.
