You are in the Nissan Xterra Forum. Your Hosts are steve_ & tidester
We are up to 15.5mpg in the city...we almost 2K on the odometer. We will be taking it on a 900 mile round trip this week so I will post those numbers when we get back.

Thanks for letting me know I am not the only one. Like the dealer said it is only me getting horrible gas mileage. I have never had a six cylinder get such poor mileage and I have had different six cylinders since 1975 (a 1966 model). I think Nissan has changed something. At $4.00 a gallon gas they need to figire out what is getting the poor mileage and change it. Quick. Next time time Toyota.

Y'all drive a lot faster than I do and my driving is on low rolling hills, so perhaps that's why my V-6 6-Speed Frontier Crew Cab 4x2 is yielding better. My 22-1/2 to 23 MPG is at 65 to 70 MPH. As y'all know, wind resistance increases geometrically -- fuel economy losses at higher speeds get worse by leaps and bounds with each small increase in speed. Frankly, my brain is too puny to react at 80 mph (117 feet/second!)  To pdclay, the Xterra has a traditional 5-Speed geared automatic transmission -- it's never had a CVT, in North America at least. I wonder if it would do any good to disconnect your battery cable for an hour and let the computer reset. I just got my truck back from the dealer and my MPG is bad because it has to re-learn my conservative driving style. At least I hope that's the problem! |

Well, I've now logged about 2500 miles in my new 2008 Xterra S 4WD with manual transmission and I'm averaging 21.7 mpg. Almost all that mileage is highway and I use the cruise control probably 70% of the time and set it at about 75... I've noticed the milage is considerably less when I've been up in the hills offroading, but I think that makes sense. All in all I'm quite pleased with the mileage but not so excited with gas approaching $4/gal... |

Man, you guys are lucky...getting 20-something a gallon on the highway. I've got an '06 with the 6-speed and 2WD, which gets me somewhere in mid-teens range. That's including freeway driving, which is where most of my 32,000(almost 33k now) has come from. When I bought this Xterra in September of 07, it had just over 12,000 on it. Now, isn't fuel economy supposed to increase as the engine is broken-in more? Or is the Flowmaster muffler I have on it robbing me of efficiency? Hopefully putting a cold-air intake on it(yay for stimulus check!) will get me some more economy... |

Hello, Just purchased X model 4x2 6 speed. 1st 3 tanks so far have ranged between 20-22 mpg in mixed driving. Amazing for a new car! |

ok guys..... i am hoping to get everyones opinion....... many xterra owners have had their fuel gauge malfunction and also their purge valve on the carbon canister on the fuel system....... for those who dont understand the system , the fuel tank has a vapor line that goes into the carbon canister to collect the fuel vapors and to be released into the intake..... the carbon canister has 3 hoses.... breather from tank , line to engine for vapors, open breather line attached to the purge valve that is no more then 8 inches long and attaches to the inside of your xterra frame...(open to be exposed) so having rolled 100,000 last week, i feel that even through i am not a mechanic i can give my opinion through my own dealings with the carbon canister and purge valve.... my valve went out at 44k..... replaced and 56k miles later again service engine light came on..... the only thing is that my fuel gauge has not worked for over 5 months since the company was paying for my gas.... now that this arrangement has changed,, i felt the need to know my mpg...... filled up on friday pass the full line.... and 25 miles later..... its showing 3/4 ...... yes 25 miles for 1/4 of gas!!!!! i have taken care of my truck like a kid.... 3,000 oil changes.... 30k service at 25,000 miles.... 60,000 miles transmission fluid..... 88,000 transmission fluid change..... radiator hoses changed at 88,000 spark plugs changed also at 88,000 miles... so what gives??????? your xterra 2005 and up has that open air line for the carbon canister... everytime you go off road or on dirt roads,,, you are exposing the dirt that gets into the frame of the xterra..... your system is being polluted .... when i just changed my purge valve last week,,, i found a ton of dust and dirt... took carbon canister and used a compressor to blow into the canister through the fuel tank breather line wich blew out a ton of dirt and dust out of the purge valve fitting.... so the dust in the system made its way into the intake area and i believe that my spark plugs are fouled from the dust........... this means that everyone that off roads needs to understand how the carbon canister works..... and a filter or longer breather line into the inside of the xterra needs to be placed.... i dont think anyone wants dust to be going into their intake via the fuel vapor line from the carbon canister line...... i hope that everyone can check with their personal mechanics and get some feed back into this situation............ so does it mean that the off road model has a filter on that breather line?????????
