Nissan-Sentra: Close to hypermiling

    I looked it up and apparantly the sentra I am driving has an epa of 28 in the city. By my rough calculations (totaly not accurate because I'm guessing on both miles driven and fuel used) I'm getting about 25. I feel good that I'm likely getting close to epa. I just miss getting a minimum of 40 in my HCH and watching the fuel gauge go down day by day is awkward.

    Hi Tom:

    ___To bad you didn’t have access to the upcoming Versa instead of that ancient Sentra. I bet the FE would have been much different. Still not anywhere near HCH territory but at least better then the Sentra ;)

    ___Good Luck

    I think a properly-driven Sentra - esp. w/5spd - should deliver pretty good mileage. I had an 85 Sentra that was good for near 40, when trying. The ones from the mid-90s w/16V 1.6L engines were excellent cars - much more refined engines than what my Escort Wagon has (heck, anything is more refined than the 1.9 - but it works!). Very snappy performance. The 2.0 Sentras of mid-early 90s were just too much fun, but with nowhere near the MPG numbers.

    If I didn't like the Wagon so much, I'd drive a Sentra.

    You SHOULD be able to do pretty good with the Sentra. I own an older Altima, and am getting over 37mpg combined city/highway. My goal is to crack 40mpg. I had an ancient Sentra (1982) when I was in college and got 40+ with it despite the fact that it was pre-fuel injection. Of course, the engine was a bit smaller than what they put in the later models.

    Shoot, my alignment must be WAY off. I'm in a 2000 Altima and have a hard time cracking 32 combined.

    Yeah, 37mpg is pretty good with an Altima.

    Is yours a five-speed or auto? Which engine? I don't think Altimas come with small engines... it's getting to be a pretty big car nowadays.

    It is a 5-speed. The year model is 1997, although I actually bought it new in 1996 (you know how they release the year models during the summer of the previous year). It has over 184,000 miles on it. The CV joints are bad, so I am having them replaced as I write this. I'm hoping that will prevent future alignment problems and improve the MPG even further. The engine in it is the 2.4L 4-cylinder. That was all that was available at that time. It is the GXE version, which didn't come with some of the fancier bells and whistles like the SE or the GLE did. I believe they are slightly bigger these days, and there is a V-6 version as well. The Altima's overall size and weight has increased too, which doesn't help the situation.

    I don't carry much extra cargo in the thing, and I'm usually the only passenger, so I do manage to keep the weight down. I overinflate the tires (just a little), use synthetic oil, and I will take advantage of opportunities to draft. One technique that I really like is skip-shifting (I don't know if there is another name used for this technique here). In addition to taking my time accelerating, I will frequently shift 1-3-5 instead of going through every gear. I try to shift around 2000RPM. I find that this gets me up to a good cruising speed in a conservative way, and puts it in high gear sooner than normal. I kind of baby the car along, and it rewards me with much better gas mileage.

    Mine's a 2000 5spd. It weighs just over 2500 (funny how heavy cars are now). I've gotten 36mpg on a commute once.

    Actually, considering my '02 Elantra is at 2630lbs, that might not be far off for a year 2000 Nissan.

    Just looked it up - 2875 lbs. with manny tranny. For some reason I thought it was in the 2500-2600 range.

    Still weighs less than a 2 dr Rabbit does now.

    Hey, that's nothing to sneeze at - especially with the heavier 2000 model. Have you ever tried skip-shifting? If not, I wonder if you might give it a try and let me know what you think. I like it, and feel like it helps the MPG #s. But I could just be crazy....

    Generally speaking "skip shifting" will put you at a higher RPM than is really efficient. Typically you'll get much better results by moving through all the gears and shifting at no more than about 2K RPM. The only times I exceed that RPM are when I'm pulsing for P&G work and when I'm on the highway and the gearing isn't high enough to keep me below that target.

    I'm still working with the difference between low accel and and high accel for FE, finding out what's best, but I feel that you want to use all the gears available to keep it in the sweet spot. Currently I'm shifting low on straights ~1500 rpms. Scanguage DEFINITELY helps.

    Oh, and I use quick shifts - sport-like shifting to keep it on when it's on, because it takes a second or two for the needle to fully descend, wasting gas.

    Well, I really don't rev the engine over 2000RPM when I'm skip-shifting - I just end up accelerating slower and getting into a higher gear faster...........

    My experience with Nissans - should be able to get some good numbers over EPA.

    i have a 2000 GXE and have increased my City MPG to nearly 30,
    Has been a long time since i took a highway trip to gage the actual Highway MPG.
    Have scangage on order to really fine tune the numbers.
    I try to keep RPM under 2K ( have asked for BSFC plots on several Nissan forums to no avail). With the Scangage i want to test some TP on acell for overall MPG ( would faster acel give me an overall improvement on MPG?)

    I have pondered would it be possable to put a 1.8L sentra engine into the Altima? Not that i would - more like a "Thought Experiemt" the QG18DE has a nice Torque curve - as i never get up to the max HP - the heavier Altima with 1.8L would be interesting

    (in realty it us easier to use the Sentra itsself)

    Good to see other Altima owners here. ( any specific Nissan Tricks you have??)

    I had a 08 sentra 2.0L cvt for a loaner. 25-33mpg was sticker. it had a ave. mpg guage, it read 25mpg so i re set the guage and drove 2.5hrs /75-80mph all the way up and got 33.3mpg. 2100-2200rmp at those speeds that is nice for a 4cly. on the way back I was easy on the speed- 50-55mph and came out with 40.6mpg one spike at 44mpg down the bridge. thats double the mpg i get in my truck.

    "Good to see other Altima owners here. ( any specific Nissan Tricks you have??)"

    I see this thread is getting kinda old......and I haven't posted in a while.....sorry 'bout that.

    My Altima is an older one (1997), so it might not be practical to compare my results with the newer models. BUT - I'm getting some pretty good tanks. Surf over to the mileage logs and take a peek - it might surprise you what an Altima can do. There is a fair amount of time between my tanks - I only drive the car about once or twice a week. I have a company vehicle I use for work, and I haven't been posting it here (although maybe I should - I've been practicing with it, too - but it is a far different vehicle - a 2002 Ford E-150 4-speed V-8).

    I can't say that anything I do is specific to the Nissan, except that I am REALLY used to driving Nissans. The car I had before the Altima was a 1982 Sentra, and it could get some really good mileage, too (although I wasn't trying so hard back then).
