:D Now that some of you have the Nitro. How is the fuel mileage? Everything I have read says it is not good or not what the sticker has printed on it. I ordered my R/T:D sight un-seen, I saw the photo and had to have it. No matter what the mileage is I am keeping it.

When I first got my Nitro it was getting 16 t0 17, one month latter its up to 18.5 . I think it will get better after 3000 miles. I drive with a light foot and live in the country. My last Dodge Ram 1500 took a year to get top mileage.

I have almost 4000 miles on mine now and I'm getting an average of 22 mpg. This is a combination of city and highway driving. I commute an hour to work everyday.

One thing I have noticed, if I use chevron, I get better fuel mileage. I noticed this when I had my F-150 also. Don't understand why. Thought maybe it was because of the engine size in the F-150 because it didn't like 87. It would spit and sputter like it was being choked. In the beginning with the Nitro it didn't seem to matter, but now that it has a few thousand miles on it, I can see a noticable difference.

Anyone notice anything like that?

I get better mileage and it runs better from BP. Some gas causes mine to bog before it catches and takes off. High flash point or something screwey.

I just had my onboard computer reprogrammed today at the dealership and I must say that the surging sensation seems to have gone away. The technician thinks that the mileage will get better too. 3600 miles and its first oil change. Woohoo!!!

22.07 after flashing the computer. Took "guzzle" to OC, MD and back (approx. 97 miles driven) and it took a little over 4 gallons of gas. Much better mileage now.

On my 3rd tank. 1st tank 15.9 and a lot of that was highway:mad: 2nd tank 14.17 :eek: and this was mostly city stop & go.

Yeah, hope the engine "loosens up" and I see at least the advertised mileage. What's this "flashing" the computer? Should the dealers know about this?

on my R/T on the first tank of gas averaged 17.8 MPG city driving. This is in michigan with cold weather (cars get worse gas milage in cold weather)
Cant wait to get a few thousand miles on her to see how she improves (and the weather gets warmer)

Drove almost 300 miles this weekend, snowskiing at Schweitzer Mt. and then out to Diamond Lake, 2 - 4 lane highways averaging 45 - 65 mph. Ended the weekend with a 20.7 mpg average.
Had a stretch on a 55 mph highway right right after I gased up, averaging 23.1 mpg. Then drove 18 miles up a windy, potholed mountain road at 25 mph & probably only got 16 or 17 mpg.
I felt pretty good with 20.7 for the weekend. Almost due for it's first oil change. Hope to get a CAI on it soon too. Maybe it'll go up.

It resets the cp in the car. I did this on my 06 charger It's real easy to do your self... All you need to do is pull some fuses and take off the "-" battery cable and turn the car to the on pos. I need to look for what fuses you need to pull...It takes less than 5 min to do....And from what I herd its good to do every 6 months or so....

Actually that is not really the correct definition of flashing the engine computer. "Flash" refers to changing the program in the Flash memory chips of the engine PCM. For example some of the TSB's refer to flashing for a transmission fix. These flash upgrades change the computer instructions to the engine transmission and other fancy controls on the car.

What G-Money is referring to is clearing the engine temporary memory registers which is quite different that changing the firmware. The procedure he suggests is often helpful to clear a fault codes and such from the engine PCM. For example after replacing a bad O2 sensor, the fault for "bad O2 sensor" will remain in the PCM even after the sensor is replaced. Powering down as mentioned will usually clear this fault out of the memory.
