#37 of 1070 98 EXP XLT 5.4V8 by dardson Sep 30, 2000 (4:43 am)
I have been religious about keeping my milage...for some odd reason (why bother is you're gonna buy a 2 ton car). Let me say first, that I have loved this great big thing. I drive 95% city and get 11.5 summer with AC and 12+ winter without AC. Road trips I do really well to get 17 but mostly 15.5 to 16.5. That said, I am not a conservative driver. I make "jack rabbit" starts and feel free to kick in the passing gear. If I can get behind an idiot who is willing run interferance 95 down the interstate, I get behind and keep up. Made a 350 mile trip last week averaging 81mph (based on miles divided by time) and got 15.9mpg. I have never, once, gotten the promised 13mpg city or the 18 mpg highway in my giant gas hog. But considering my heavy foot I am not surprised. Being a child of the 60's when 8 or 9 city and 10 or 12 highway was the norm, I'm only amazed they can make 2 ton cars that get 12/16.

Currently averaging 21mpg (US gallon) combination city and highway. One time best of 24. Worst 16 all city. The past few tanks have been constant at 21
#39 of 1070 update milage by dardson Oct 02, 2000 (1:33 am)
2 posts back, I mentioned a pretty consistent 11.5 mpg on my Ford EXP 5.4V8. A few weeks ago I happened to be reading my owners booklet and noticed it said to use minimum 87 octane. I had seem on some post somewhere that reg. gasoline in higher altitudes was 86 rather than 87. Sure enough, last time I filled I noticed 86 octane for reg. unleaded. I filled with mid grade 88, checked the milage yesterday when I filled again, and got very close to 13 instead of the the usual 11.5. Interesting. Not sure it's meaningfull as I paid 10cents more per gallon, but I had no idea a few octane points made such a difference....and I have a seat-of-the-pants feel that the car is distinctly quicker. Hum???
#40 of 1070 Knock sensor by tbavis Oct 04, 2000 (12:31 am)
The 5.4 may have a knock sensor that causes the ignition timing to be retarded more with the lower octane. Maybe not enough improvement with 88 octane to pay for the difference, though. I have two 3000 lb cars - a Subaru Forester, which does about 26 MPG commuting, and a Voyager, which does 23. Funny, my '73 Subaru and '77 VW only managed 26, and they were 1880 and 1800 lbs!

Just did a 350 mile trip this past weekend. 1st in this vehicle. Got a solid 20 mpg. Kept it mostly to 65 mph but includes a good 40 miles of crawling around town. Replies to this message: dooleey (Aug 18, 2005 7:41 pm) stevedebi (Aug 19, 2005 12:42 pm)
#42 of 1070 2001 Ford Excursion by dmez Oct 05, 2000 (2:28 am)
I only have about 700 miles on our new truck. Drove it to upstate NY this past weekend and maintained about 15 mpg on the highway and about 11 mph around town. Trip was about 300 miles round trip. Speed was 65 mph to 70 mph.
#43 of 1070 2000 Suburban 5.3L 3.73 gear 4X2 by selman Oct 06, 2000 (5:46 pm)
City avg. approx. 13-14. Mixed avg. 15-16, Haven't had an opportunity to check Hwy. only. Mileage decreases about 1-1.5 MPG when pulling 1500 to 1800 lbs. (2 waverunner/gear).
#44 of 1070 2000 RX300 by itzkirb Oct 06, 2000 (6:43 pm)
City/Highway(SF Traffic) average overall about 21mpg. only 2000 miles on the car so hopefully it will get better with time.
#45 of 1070 Disgusted 4-Runner owner by mark_aidan Oct 17, 2000 (12:56 pm)
I purchased a 1999 Toyota 4-Runner Limited about 3 months ago and have been having a real problem with fuel consumption. The mpg was listed at 17-20 mpg highway with a tank that is to hold 18.5 gallons of fuel. Neither of these stats have held true. First, my suv will only hold 13.5 gallons and I have averaged 180 miles per tank of gas over the 3 months. Now simple math tells me I am still only getting 13.33... mpg. My questions are: 1) Have any you 4-Runner owners had these types of problems with this make/model. 2) Why will this suv only hold 13.5 gallons of fuel(this has not changed for 3 months also). And 3) Is there a recall on the 4-Runner for problems will fuel consumption, inaccurate gauges or the wrong size gas tank on the 4-Runner. The Toyota dealership says there is no problem. I fail to see it that way. I would appreciate any information that anyone could offer up to make some sense of this situation.
