#2 of 18 2004 FX45 with 25k miles by ttummy Jul 05, 2006 (7:04 pm)
I typically get 16 mpg in mixed driving. When driving in NYC we sometimes get 9 mpg, but usually 12-13. On the highway usually 18-19 mpg. Never more than 20 mpg.   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.
#3 of 18 '04 FX35 by texasfx35 Jul 07, 2006 (12:45 pm)
I own a '04 FX35 (tech - no sport pkg) with 42K miles on it. I am a fairly conservative driver living south of the Houston metro area. Under normal everyday driving, which may include 20% highway miles, I will get 17-19 mpg on a tank full. Driving the posted 65 mph on the area freeways, I will easily get 25-26 mpg. If I drive a steady 70-72 on an extended trip to other metro areas in Texas, I usually will get 23-24 mpg. The FX35 engine does have a voracious appetite for gas if you have a heavy foot, which is the price you pay for moving that much mass at a good clip. I can drop the above mpg estimates by 15%, if I just want to have a little fun with the performance side of the vehicle.   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.
#4 of 18 2003 FX45 Milage by wvgasguy Oct 23, 2006 (10:42 am)
Before I traded it, my 2003 FX45 averaged 16.3 mpg over 30,000 miles. I didn't think it would do any better but when the old guy came and picked it up for service I reset the trip computer and he got 18.5+ over the 250 mile round trip to the dealer and back.   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
#5 of 18 Premium Unleaded? by vanpool Dec 28, 2006 (4:44 pm)
I just purchased an 07 FX-35. The manual suggests premium unleaded, but I would like to hear from some of the owners to see if they are using a mid-grade without any problems.

Replying to: vanpool (Dec 28, 2006 4:44 pm) I have an 04 FX35 and have always used medium grade with no problems. Enjoy the car, I love mine. Jon.

Replying to: vanpool (Dec 28, 2006 4:44 pm) I also drive an '04 FX35 with 50K miles on it. For the last couple of years, I have alternated tanks full between premium and mid-grade with seemingly no negative effects. Maybe a slight increase in MPG with premium, but hard to be sure. Nevertheless, on my last visit to the dealer, the mechanic recommended I get the fuel injectors flushed. The engine does "pop" sometimes on initial start-up, but other than that no other symptoms (rough idle, poor MPG, etc). Not sure if this is the result of using the lower octane fuel, which also would have fewer detergents in it, or not. But when you do the math, a driver getting only 16 mpg average and driving 16K miles a year would only consume a 1000 gal of fuel. At a $0.10/gal difference in price (in Texas at least) between premium and mid-grade, that is only $100/year savings. The extra depreciation from driving 16K vs 12K is closer to a $1000. The cost to flush is about $125. I guess what I am saying that if you are going to drive a $40K automobile, it may not be cost effective to save $100/year using a lower octane fuel. It may even cost you more in the long run. Replies to this message: vanpool (Dec 30, 2006 12:11 pm) msticks (Feb 20, 2009 12:16 pm)

Replying to: texasfx35 (Dec 30, 2006 11:05 am) Thanks for the post. So far, I have only put the premium in the FX, and I will probably stay with the higher grade. I will put about 20K miles per year, so it may be better to use the premium grade.

#10 of 18 2007 Mileage by vanpool Jan 02, 2007 (2:51 pm)
I only have about 1,000 miles on my 2007 FX 5, but so far I have been getting 18 - 20 intown and about 24 on the highway. Using premium grade fuel. Replies to this message: keithsea (Jan 05, 2007 5:57 pm) vanpool (Jan 05, 2007 8:01 pm)
