I seem to not be getting very much mileage out of my R/T. I use 94 octane, synthetic oil, and have changed my CAI.
Is anyone experiencing a similar problem, and if so, what have you done to remedy the situation?

Poor Fuel Economy

After putting about 6000miles on my RT I seemed to have levelled out at about 17-19mpg. Thats not driving it hard, 87 Octane, and Castrol synthetic oil. I was getting better mileage, 19-22mpg but it seemed after I had the tranny leak fixed it dropped some.

No one's been able to explain it to me.

Why are you running 94 in an R/T???

Recommended is 89.

I'm averaging 20mpg a tank with 89 and a semi-synthetic at 4000 miles. Switching to a full syn at 6000.

I watch my MPG pretty carefully. Using 89 octane, my Daytona was generally getting between 21 - 23 MPG in highway driving (70 - 75 MPH average). When the temperature drops to around 75 F, the MPG gets much better on the highway -- upwards of 26 MPG on average. I use synthetic oil and have an AFE air intake.

I just started using 94. I am in Canada. I have 48,500km (not sure of that in miles), and am getting approx 400km (miles?) on a full tank.
have you noticed the drop after you started to use the 94 octane or before? Maybe that's just too much octane for what your car needs...there's been a lot of discussion on this recently. Do you have a tune on your car? If not, then you don't need to run 94 octane...89 is recommended. The car is tuned for 89 but can survive on 87 if needed to.

I just completed a 360 mile round trip to Ottawa on 91 octane and averaged 23.7MPGs with 3 adults and a 12 year old in the car as well as a loaded trunk...just for comparison's sake.

10-4 on that. I just entered some of the outstanding fuel receipts into my spreadsheet (I have one per car) and saw that in May on a trip back from Toronto, I filled up just before hitting the highway and filled up again 1 whole day after returning to work (that's commuting in traffic to daycare, then more traffic to work, then traffic to daycare, and heavier traffic back home, then filling up the next day). The result: 25.something MPG US.

That was with 2 kids and 2 adults in the car, also with a full trunk.

If I had taken the time to fill up immediately upon arrival, who knows what kind of fantastic result I would have logged! :knockout:

That was a steady 105-110 kph the whole way, with 2 food stops along the 401. Esso 87 on the way down.

lol...I was trying to keep it a steady 105-110...but I HATE it when others pass me and I pass no one! I had a few sprints to 125 just so that I could say that I passed someone! Really...I kept it pretty much in between those kph that you stated...I found it to be a good compromise between achieving decent MPG, and getting to our destination in a reasonable time frame! I mean, I could have cruised at 80kph but that's just downright dangerous! Today, doing 110kph, I was passed by a Ram on the 40 pulling a nice sized camper behind it doing about 120! ...

hey Steve...I'm sure if I drove like grandma all the time, i'd achieve those number that you had!

:) LOL!

Fact is, the 401 is a killer, and I mean in a mortality sort of way. EVERY time I make the MTL-TO-MTL run I ALWAYS run into a deadly accident. This past May it was on the way down to TO, at 10pm traffic was backed up for miles with no way to get off the highway. Finally, we all managed to funnel out through an exit into some small backroads, and that's where my NAV really came through for me and got me back on the highway after the incident. Imagine the feeling of pride as I turned off into a small back road while all the other cars kept heading for the small town in order to follow the "official highway" path! :)

As one gets older the self-preservation gene usually kicks in, and when on a highway like the 401, you just try to follow traffic and minimize zig-zagging.

Today's math lesson

1 kilometer = 0.621371192 miles

1 tank of gas gets you 400 kilometers or roughly 249 miles

You have approximately 48,500km on your car (approx 30,136 miles)

If this information is correct, you are getting about 13-15 mpg :knockout:

You car is by all means broken in. I have 36K on the ride now, and I'm getting approx 25-28MPG with 93 Octane and Mobil 1 full Synthetic. Are you a city driver, and should you add WOT to the end of your name like its a professional certification? If neither case applies, you should at least be getting 20-22 on average.
