Re: Hemi Gas Mileage?

I run Hess gas mostly (or Sunoco). I run strictly 89 octane to get the mileage I reported above. When driving for MPG's I try to keep the car in Eco Mode and I try to minimize uphill acceleration. I also am very conscious about smooth driving.

At the same time though I bought a 5,000lb. SUV with 360hp V8. I wasn't expecting anything great. If you want high MPG's this is probably not the car for you....

Correct, I didnt buy it expecting prius MPG, but if people are averaging 14-15 mpg compared to 11-12 thats 3-4 MPG increase per tank. So lets say 4mpgx21gallons or 85 miles extra per tank. That equates to roughly 5.5 gallons of gas or ~20.00 a tank. Could be a savings of 60-80 bucks a month for people who fill up 3 or 4 times a month for the same exact vehicle thats all.

Re: Hemi Gas Mileage?

Yeah, I'm in the same boat - I'm averaging about 13mpg, and that's about 60% city...even when I take a highway road trip I'm averaging 17mpg...I do use remote start quite a bit right now in the cold, but I have been pretty good about avoiding lead foot.

I also use name brand gas, 87 octane, but same as Jorde, it's 10% ethanol.

Re: Hemi Gas Mileage?

Mostly highway driving I'm averaging 16.5-17, using ACC when I can. I was hoping to at least get to the EPA sticker mpg--first car in awhile where there was this much of difference between the EPA sticker and what I'm actually getting--usually I get slightly better than the EPA.

Hemi requires 89. Try that first.

Re: Hemi Gas Mileage?

13.5 - 14.0 city if taking it easy. tons of stop and go and it's at the low end. highway is high teens, maybe 20 if flat and can be smart with above techniques mentioned by litespeedz. this is at altitude with 87-89 fuel (no E85).

good indicator how tough it is to move a 5k rig, reset your EVIC MPG screen and give 'er some pedal or do basic stop and go. this kind of driving is definitely single digit MPG.

Re: Hemi Gas Mileage?

I dont know why people even still mention 10% ethanol. Its been that way for like a decade atleast here in the Chicago area. I assume that to be normal these days. As far as how much that effects the cars performance, well IMO cant be that much because every car I have owned gets better than listed fuel economy. My current Lexus ES300's window sticker says 19/25 for fuel economy and I get 23/30. My C6 Z06 Corvette's sticker says 18/25 and I get 20/29. All im saying is that the numbers I get are very good so it seems that the 10% ethanol cant be hurting thattttt much. I dont have a WK2 Hemi yet so I cant comment on those yet, but considering how my other cars do compared to the window sticker and the type of driving I do I would also assume better than the listed 13/19.

You do not see if much in NC, SC, TN, or most of VA. You only start to see if when you get close to the DC area.

Oh ok well I guess I can only speak for the Chicago area then as its been here for as long as I can remember. And like I said my cars all get amazing fuel economy compared to the stickers ratings. So IMO the effects of 10% ethanol in our fuels is nothing to really even think about. I mean its not as if I have a choice in the matter anyway, atleast here.
