We've had the C for a little over a year. It just turned over 15000 miles on a 720 mile trip from western PA to South Carolina today. On today's highway trip, travelling almost always between 70 and 80 MPH, the mileage on the EVIC shows 22.9 MPG. At a slower highway speed of 55-60, it showed about 25 MPG. Around town we are getting about 16 MPG. Those figures are almost exactly what I have been getting using the fill and calculate method. I often have the joy and urge to put my foot into it, too. So I would say DaimlerChrysler gave me the truth about gas mileage on the sticker.

I purchased my 2005 300c, new in March of 2006, having just over 400 miles on it. It is virtually loaded with almost every option except Sirius radio, and a DVD player. Initially, I had a problem with the car leading to the right. After 4 alignments, and fine tuning of my alignment, and the discovery that the tread on all 4 tires was half gone after only 7000 miles, it was decided that my Conti tires were defective in materials and workmanship. Continental agreed to reimburse me for ONE tire, only. I replaced all four tires with Goodyear Assurance tires, and my lead off problem is now history. The car handles like a dream, even on the rural roads of Ohio, which tend to be crowned, and uneven. My MPG, prior to solving the lead off problem averaged around 21 combo driving, and 24-25 hiway driving at 60mph, and no air cond. After mounting the Goodyears, my MPG average went to 23.5 combo driving, and 26-27 hiway driving the same roads at 60mph, and no air cond. I then had the Chrysler dealer change my motor oil, automatic transmission fluid, and rear differential gear lube to Amsoil synthetic lubricants. I now have just over 9000 miles on the car, and my combo driving has risen to over 25MPG, and my hiway driving average on the same roads at 60mph, has jumped to over 30MPH. I have used Amsoil lubricants since 1978 in every vehicle that I have owned, along with every vehicle that my 6 children, and their spouses own, with absolutely no problems. I use the 5w-20 motor oil that both Chrysler and Amsoil recommend for this motor, and I change it every 6000 miles, as the Chrysler manual recommends for synthetic motor oils. All synthetics are not the same, just as all paints are not the same. It's whats in the bottle that counts. Check out, and do some research on your own about the Amsoil lubricants. Compare their specs against the specs of other brand name synthetic motor oils. But if you want your vehicle to get the best mileage that it possibly can, do your own homework. As for me, I love my car, and aside from the initial lead off problems, I have nothing but praise for this Chrysler product. It is the 4th Chrysler vehicle that I have owned, the first three being LHS models.

stop & go city mileage

I presently have a Cadillac DTS and drive 90% of the time in stop and go traffic in the city. I get between 10 & 12mpg with this type of driving in the summer with the A/C running. I'm curious what type of mileage I should expect with the 300C when it's only running on 4 cylinders most of the time. I'm curious if the cylinder shut down makes much difference.

The worst I've every gotten was 12 mpg (per the dash computer) during an almost 2 hour housing tour with four people onboard through the chic area of town where I never got above 15 - 20 mph and was stopping every 300 ft. or so. Normal in town only driving gives me 16 mpg to maybe 18, depending on traffic.

I have a 2006 300C SRT8 and consistenly get 12-13 mpg in city driving and 18-19 on freeway. Not too bad considering 425hp. I had a 2005 Nissan Xterra with 265hp and was lucky to get 14/16 mpg! Plus the SRT8 is a BLAST to drive!

I have a '06 300C. I keep track of all gas purchases. After 21,400 miles the average MPG IS 19.0. We did a trip in August of this year from southern Wisconsin to Colorado Springs and back. The average for that trip (actual fuel used) was 22.6 MPG. The morning we left I reset the on-board calculation and when we arrived home after 2460 miles the on-board calculation said 22.4 MPG. To those 300 owners out there who doubt the on-board computer calculation, I would have to say it is pretty accurate. More than 50% of my miles are city driving, which gives me between 17-18 MPG. The open road travel, like our summer jaunt, with alot of 75-80 MPH cruising gives between 22-23 MPG and the local short trips on state highways (55 MPH limit) will run 25-27 MPG. Of course the MDS (cylinder shutdown) makes a difference, that is why Chrysler is using it.

Just did a trip from Tulsa to Dallas, 100 miles around Dallas, then the return. Expressway speeds were 70 or 75 (cruise set) primarily with some 45 - 65 areas for construction. A lot of stop and go during rush hour on the Dallas expressways. A/C was on all the time. Average for the whole trip was 25.1 mpg. I'm impressed.....

The "worldwide Official MPG calcuation" would be liters per 100 kilometers. This is the number of liters of fuel used per 100 kilometers of driving. One hundred kilometers is about 60 miles, so 24 MPG is about 2.5 gallons per 100 kilometers, which is about 9.5 liters per 100 kilometers.

E-85 is 85% ethanol, 15% gasoline, and is only for engines designed to run on E-85. Most engines are designed to run OK on 10% ethanol, 90% gasoline.

I've driven my 300C AWD over 21,000 miles and never gotten above 19 mpg - not on trips, not using various brands and grades of gasoline, not with the AC off, not ever. Mixed driving gives me about 15 mpg. I traded in my Escalade in order to get a more fuel efficient car. Wrong! The Escalade was much better on city and highway results.
Before you ask why I purchased a Hemi if I wanted better fuel economy... A) I need AWD and of the only two AWD's that came to dealers nearby in the spring of '05 and both were Hemis. B) I somehow believed that my results might be at least somewhere near EPA estimates.
