| PowerStroke Diesel Excursion Limited .With a 44gal fuel tank I Can drive all day non stop. | |

| I have a 1999 limited 4-Runner. This thing has the worst gas mileage. I get around 11-13 city and about 15 on the highway. I read some of the other columns in here, and found out I'm not alone. Many, many 4-Runner owners are disgusted with their fuel consumption. So if you people are interested in a new 4-Runner, look closely at the mileage to and from where ever... You might want to visit a Nissan Dealership. | |
| I usually get about 17 to and from work. 35 miles each way, mostly highway. | |
| I hardly think your problem is widespread. You are only the second person I have heard this happening to here on Edmunds (the other one is covo). I get great mileage (for a truck) with my 1998 SR5 4WD. | |
| I get almost 20 mpg in light suburban commuting. No highway trips yet. | |
|
12 ~ 14 mpg local / half half commute. 17.9 mpg free ways. |

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 |

| 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!
