People in NJ and NY tend to drive very aggressively. I would say that when it is safe to do so, I like to use the extra two cylinders I paid for, but don't weave in an out of traffic, for example.
We live in an EPA non-attainment area, so our fuels have 10% ethanol in them. Contrary to what has been touted that these fuels give poorer mileage, I believe I have noticed a slight increase in mileage since the switch, but this could be the result of me just driving more conservatively than usual with the current gas prices.
Wow I thought, maybe I am driving it too hard.
Anyway I traded it in May. I will say it was one of the most satisfying automotive experiences I've had
I bought 2006 FX45. I am getting an average of 16 miles per gallon on this vehicle in mix driving conditions. I live in Chicago area.
Thanks,
5, but so far I have been getting 18 - 20 intown and about 24 on the highway. Using premium grade fuel.
Since October in my 2006 FX45, I'm only seeing 11-12 mpg in Seattle area (ouch), with premium unleaded. That's a lot of stop and go traffic and hilly surface streets, but I still only see ~14 on wide open 60-70mph highway. Have yet to see a '15' on the mpg screen.
Any other FX45 owners out there able to comment on their mpg?
There are several factors that I've found help MPG:
1) Check you tire pressure, I found that 35 PSI cold presure helps over the stock 32 PSI.
2) Put in an aftermarket air intake or at least a K+N filter. I got about 2mpg just from installing a K+N filter and the car feels faster, though I haven't dynoed to see if it actually is more powerful.
3) Install lowering springs. Just 1" lower and you will get better handling and a slight improvement in highway MPG.
4) Turn off the air con when possible.
5) Drive with the windows up.
I have a 2006 and average 16.2mpg. I drive it kind of hard because that's what I bought it for. I asked the Mercedes dealer what the gas mileage was on an E 350 I was checking out and his response was most Mercedes drivers don't have to worry about the mileage. I agree and 16.2 is the result. This thing is a beast and needs to be drivin once in awhile. Drive it like you would if the mileage didn't matter. If it does matter, get a Prius. Drive on my FX45 family, drive on!
On avg, I got 17mpg around rural town, with a couple of 20 and 21mpg on long distance road trips with mostly interstate/highway driving! This though was with using Hess and Exxon Premium gasoline; I switched to Shell Premium on all my vehicles about a year ago, but I never used it while I had my 2005 FX! I have seen incredible improvement in avg and long trip mpgs on my current vehicles with the switch to Shell Premium and wish I had done it long ago while I had the FX! I think I would have seen a 2-3 mpg improvement!
God help the FX45 and FX50 owners with the V8 though, I don't know how you guys do it with the V8 and fuel economy! All the power to you though who do have the V8!
I remember back in 2008 I think when gas prices got up to $4.30 a gallon here for Premium in NJ, I got killed with my FX; each week the fill-up was $80-90 bucks! God did that eat a hole in my wallet! Pray and never gets up to that prices again!
