#25 of 59 loss of gas mileage after coil replacement by azzankel Jul 27, 2006 (5:43 pm)
A few months ago, I had a faulty coil in my 2000 Maxima SE 5 speed(52,000 miles). Had it replaced at a dealership, but "service eng soon" light came on a few days afterwards. Took it back in and they couldn't find a problem (car was running great)and reset the light. Few days later, light came on again...took it back in. They recommended that I replace remaining 5 coils. Since they could not find any problems, and car was running great, I decided to live with the light on rather than spend $700 more. Had always averaged 23-24 in town, and 29-31 on the hwy for the 5 1/2 yrs I've owned the car. In a few weeks, car started acting up and it was a rear coil. Had remaining 5 coils replaced at that point and car still runs great. Here is the problem......my highway miles now are 23-24, and my city miles are 21-22. Took it into the dealer and they can't find anything wrong. Everything is within acceptable parameters. Any ideas why I lost 100 miles per tank full on the highway, and 10% of my city mileage? Again.....this problem started right after I had remaining 5 coils replaced. Anyone have any ideas? Thx!! Replies to this message: dmaljunk (Jul 31, 2006 7:21 pm)

#27 of 59 Just recently found this site.... by debating Aug 09, 2006 (5:45 am)
Purchased our 2000 Maxima SE used in '01, still have it. Still impressed with it. We had all the coils replaced a couple of years ago, and had a sensor replaced a short time later, thats all the problems encountered. We always burn premium by the way.   Our first trip after purchasing was over 3000 miles, it impressed me with the highway mileage. One tank with 28 MPG, and the rest in the 26 MPG range. Averaged 70 to 80 MPH. Have never figured the city mileage, it's not as great however.   From the long term reliability ratings I've seen lately, wonder if the newer Maxima's are still as reliable as ours has been. Plus with current gas prices and the forecasts if a four banger Toyota or similar for an eventual replacement, or even a diesel might not be a better choice? We owned a diesel escort in the mid 80's, those 40 plus MPG highway figures would sure be enjoyable today.   But I dread reaching that point because I have sure enjoyed our time with the current Maxima.
#28 of 59 2000 Front Wheel Bearing by mj9981 Sep 03, 2006 (6:22 pm)
Hi All I have a 2000 Nissan Maxima SE. In a turn hard to the left, I could hear a metal to metal rubbing sound.To make a long story short, I removed the right front hub and found the outer bearing cage broken in three places. Prior to hearing this sound, several months ago I felt a vibration in the front end. The axle nut was loose on the right. I re-torqued the nut to specs and even safety wired it too. Replacing the bearing is a job but it can be done with a press and a tool to remove the ball joints. Happy driving!! MJ9981

Replying to: holcomb1956 (Mar 17, 2006 8:25 pm) I have 05 maxima SE.. On highway alone I get 33-35 mpg, now funny part,while driving 64 i save more than while driving 59. As an average I get 24-27 mpg with 10% city and 90 % highway ( this actually depends on a day of the week as I get stuck in traffic for 2-2.5 hr on almost every friday) I Use Gold from BP. Exxon mobil- i somehow get less by 1-2 mpg.
#31 of 59 2000 maxima by jbrusca1 Jan 30, 2007 (2:36 pm)
my 2000 maxima has 147,000 miles. I was getting 22-24 mpg until last week. It runs a little rough, but still has good pickup but my mpg went below 20 (highway). Can anybody help.
#32 of 59 Premium really doesn't cost much more by pegasus17 Feb 14, 2007 (7:18 pm)
I have a 2003 Max SE with 44k miles. Luckily, zero mx problems so far, only routine oil changes and a new set of tires at 34k. MPG in the city is 18 and mixed city/hwy is 22. Open road highway driving for 500 miles i have gotten 26-28 mpg driving 70mph. Two points: (1) the trip computer mpg is always 2-3 mpg wrong (high) (2) I have experimented with regular and mid-grade gas and have always found that the mpg suffers by ~2 mpg plus performance is not as spirited (also get occasional knock). So while premium does cost more, the car does run better. FWIW, I find BP gas (93 octane) works well in my Max. Also FWIW, Shell V-power made it knock much worse than any other gas.
#33 of 59 2007 Maxima Distance to Empty by cmyawn Apr 01, 2007 (8:37 am)
I have a 2007 Maxima SE, and I get about 23 mpg in mixed-use driving so far (only on my 4th tank). I have a slight problem in that the low fuel light comes on and the "DTE" (Distance to empty) on the computer warns I am nearly out of fuel, but when I fill up it only takes about 16 gallons (and the tank is spec'd to hold 20 gallons).   Is this behavior typical? I am used to other vehicles where the DTE is very accurate. Is there an adjustment that can be made at the dealership to improve the accuracy?   Thanks Replies to this message: alexstore (Apr 24, 2007 4:30 am) hercgretch (Jun 24, 2007 9:47 am) alexstore (Jun 25, 2007 3:41 am) hercgretch (Jun 25, 2007 6:27 am) classic57b (Apr 21, 2008 5:02 pm) andy211 (Apr 27, 2009 11:32 am) poodog13 (Apr 28, 2009 8:57 am)

Replying to: cmyawn (Apr 01, 2007 8:37 am) First thing first. Never drive in low gas, dangerous. I had similar situation and even though it was showing 40 miles left in 26 mpg (hey it was new. I can get 30-35 in highway driving alone) a full tank was about 14.5 gallons. DTE is estimate so if I were you , i will fill up 1/2-1/3 of tank.
