gas saver

[kms1990]

i average 15-16.5 ish in my 00 x with 155,000 miles on it i can get over 20 on highway if i can relax and deal with everyone flying by me cause im doing 55-60mph usually i cruise at 65 but i only get about 17-18 hwy doing that but i had many speeding tickets with the little cars i had but the x has put an end to that meandering up to speed and feeling comfortable at 55 instead of 70 has helped with road rage too i have a drop in k and n and do all my maintenance that is the biggest helper on the mpg side doing the up keep and using quality fluids and lubricants. i also noticed a bit better mpg after removing the black plastic wind deflector that said nissan from the roof rack (do to it making a ton of wind noise on freeway)

I got about 8mpg with my X. I have a small lift and tires/rims but cant figure out the reason. Ive tried the air intake mod and other small tips from the fellow members. Ill most likely get the engined checked out when I get home. Its not worth having it anymore and I haven't driven it in 2 years since Ive been stationed overseas. Definitely buying a small gas saver when I get back.

I am actually quite pleased with my xterra's MPG. It is an 2000 model with a manual transmission, completely stock except with 31" all terrain tires and k&n air filter. Using a scanguage and some light hypermiling techniques, I have been able to average 22 mpg to and from work consistently. My commute is hilly and a mix of city / hwy traffic. On a level road going 50-55mph, I have been able to squeeze out 25 mpg. The best I could do in my old F-150 was about 16mpg. I have found that my biggest enemy is speed. This thing winds up to almost 3k rpms at 75mph. Not to mention the poor aerodynamic drag, which increases exponentially with speed.

I think the main advantage is the manual transmission. It provides alot more control of your revs and throttle position. It's really too bad they don't make manuals anymore... if they did I may have to buy a new one. Are you listening, nissan?

With my Scanguage fully calibrated, and with a very light foot, I got 25mpg on the way home from work today! 3 miles city, 6 miles interstate, 3 miles hilly backroads. I am very happy with this!

thats a pretty small sample size.

I've said this before but I think it's worth repeating:

Installing fancy top brand oils, plugs, intake kits, and other whiz bang gagetry will not significantly effect your mileage. It may not hurt your X, but depending on how crazy you get, it will hurt your wallet.

Economy and performance are typically opposite ends of the spectrum. Your X was already designed by engineers trying to maximize efficiency while still maintaining enough real world performance to make the X useful as a small SUV. Installing an aftermarket intake system or filter will have no appreciable effect at anything below full throttle, and the on board computer will adjust everything accordingly to maintain the proper fuel air ratio. More air in = more fuel in. Intake restrictions are really only an issue when it comes to maximizing horsepower, not economy.

There is only one thing in the intake system that you can change that will have any noticeable effect, and that is the position of the throttle plate. Control your foot, and your mileage will be better. It's easy and free. I can easily get low to mid 20 mpg on the highway by keeping it around 60 - 65 mph.

Now THAT I believe!
