Are you just watching it fluctuate or are you saying that you are seeing an average of 6-8 after a whole tank of driving? Because if that's the case, something isn't right. On my last tank I got 9.2 avg on a full tank from normal driving conditions on E85 lol.
I am talking about the running average displayed. There was a period of several weeks after I got the truck where I never touched the highway except for the 1 mile stretch I use between my house and my office and I got as low at 6.6. Then I had a couple week period where I went on a few longer drives over 30 minutes that included longer stretches of highway and I got up to 8.5. Since then I had been creeping back down until this weekend when again I was travelling across the city a few times of mostly highway driving.
Seems like the majority of people I see avg between 10.5-12.5, so seeing 6 on 93oct definitely seems way off base. I'd be having the dealership take a look at that point (although depending on the dealership there's just as much likelihood that they will have no idea themselves lol). I do mostly city driving myself and the fact that I get better mileage on ethanol which burns 1/3 quicker than gasoline doesn't make a whole lotta sense.
I dunno what kinda city driving allows for constant WOT but to each their own lol
Eh, in my cammed Charger I used to do 7-8 mpg with similar driving, so I don't think anything is amiss. My daily drive is 4.5 miles, and if I take surface streets there are 18 stop lights along the way. If I take the highway which I usually do at night it's only 12, but usually includes a full throttle blast up to 80 then another hard blast after exiting the highway. If I lived further out and had long highway stretches to drive I would probably be around 8-9 most of the time. I also drive in Baja or Sport unless on a long stretch of highway.
*remembering back to 2003 with a cobra doing 160+* (pegged speedo) and that was with 550rwhp. Tuner registered 170+
Doesn’t take much room to get there at all. I’m just south of Atlanta, so there are plenty of good roads around here and tracks when I get the opportunity. Be safe out there
I rarely go full throttle unless its wide open in front of me, but I definitely enjoy the sound of a heavy pedal.
Fuelly
Put that beast in snow mode every time. It will help you a little bit, and every little bit counts.I love reading about the fuel mileage. Can’t wait to see how mine does on my 64 mile round trip commute
Im 7.8 with 55% city and 45% highway. I do drive hard but not super hard. My AFRs are super rich. The two tuners I have spoken to have said its do to the COT, cat over temp, causing the computer to run rich to cool them. Im at the point where Im considering trading the thing in or E85 tuning it. I have a call into the dealer to have them run some diagnostics on it as well as an oil change. Im not hopeful in the results from that visit. I knew this thing would be bad but my 69 Camaro with a heavy cammed 427 big block got better mileage and I was ripping that thing hahahaha
I go to Houston a bunch and the parking structures downtown are a joke. Insanely tight turns and always 6'10" or less. I've seen a couple raptors in the structure I frequent most and they're splitting hairs on the clearance.
