| 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 | |
| 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??? | |

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.

| 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. | |

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). |
|
| City/Highway(SF Traffic) average overall about 21mpg. only 2000 miles on the car so hopefully it will get better with time. | |

| 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. | |

My 2000 GCL V8 with Quadra Trac : City 13.5 to 14 imperial m/g haven't check highway m/g yet. |
