MPG on Altima Coupes

[mikemart]

Still doing research on Altima Coupes.My latest question is MPG on 2.5 vs. 3.5. I just don't want to regret buying a 3.5 every time I go to the pump. The extra 100 ponies and the side view markers ARE hard to pass up!!

Can current Coupe owners please respond and post avg mpg city/hwy?

Would insurance be much higher for a 3.5 for a male w/good driving record and over 25?

Simply put: I would like input regarding 2.5 vs 3.5 from current owners and hopefuls such as myself.

I've only filled up twice since I've had the 3.5SE, and I've had it since July 18th.MPG at first fill up was 24.4. MPG at 2nd fill up was 21.7. As for the time spent on hwy or city... I could estimate...if you wanna know just ask and I'll guess.

According to the trip computer, I drove 63.8 miles for 1 hour 10 min, with MPG at 28.9. Speeds varying from 45mph to 70mph with no stops.

There are many factors for deciding which engine to get. Do you want to save gas money or do you need the extra power.

Personally, I got the 3.5 b/c I need the power. There's some crazy drivers around here and I used to have a 4cyl and it just wasn't quick enough for getting out of people's way...or for turning into traffic with that little window of opportunity, if you know what I mean...

As for the insurance, you'd have to call ur insurance company to check up on that. My guess is that it would be...but I do not know the answer.

I have had my Black 3.5 SE Coupe CVT for 1 and 1/2 months.

City: 18 mpgHwy 28 mpg

It get great mileage on the hwy at 60 mph, but not too good around town.

I actually wanted to start a thread of the same nature, I wanted to see what kind of fuel efficiency everybody was getting with their coupes.

I've got a 2.5 S, and the trip computer is reporting 9.6 L/100km so far, after 3000km.

(Yes, I'm Canadian, hence the L/100km measurement)

The equivalent mpg number is 24.5mpg.

You can use the following site to convert between mpg and L/100km, so how about posting both #s in any subsequent msgs?

Great site hangtime...saves me a lot of work converting.

My 3.5 gets 10.7 l/100km or 21.9 mpg. I estimate my driving is about 65& highway and 35% city.

My numbers come from a spreadsheet where I calculate after every fill-up so these are real-life numbers. Last time I checked the on-board computer came up with a very similar result.

Thanks for the responses. I really appreciate the input. Any more feed back would also be greatly appreciated.

Before I bought my coupe I was driving a Grand Cherokee with a V8 for a little over a year. I was getting 11-12 mpg. It was terrible. So anything would be better for me. I'm getting 19-20 around town. I don't do much highway driving. The 2.5 is obviously going to get better gas mileage but purchasing the 3.5 if you can is most definitely worth it if you like the extra power and don't mind paying a few extra bucks for gas.

As far as the insurance goes. Sure your going to pay more but I don't see it being drastically more.

[hangtime23]

Another thing I'm gonna check is whether or not using premium gas makes a big difference in the mileage...I guess 3.5 owners don't have the option of using 87 octane gas tho...I'll report back the #s within the next couple of weeks, I just filled up my last tank on 91 octane gas, so I'll see what kind of mileage I get for that.

Also, my driving is probably about 60/40 highway/city, altho probably about 20-30% of that highway driving is through stop and go traffic...so it's probably closer to 50/50 highway/city...oh and I've got the CVT transmission on my 2.5S.

Any more info from any 2.5 owners?

[hattrix]

I have put nothing but 87 in my 3.5 and have been getting 24.5 MPG average for 4500 miles now. I used premium once and saw no significant difference so I didn't use it again.

[psychoffspring]

i just got my Coupe, its a 2.5... on the highway, i average 27.9 MPG, and in the city driving, i average 21.7 MPG....the airbags in the Coupe also help lower the insurance rats..the airbags r basically everywhere, lol.

[mikemart]

Thanks again for all the great info. My commute to work is about 10 minutes w/ ~ 40% hwy/60%city total per day. I live in Cheyenne, Wyoming, so I can get pretty much anywhere in 15 minutes.

Higher octane prevents your engine from knocking.. Which essentialy prevents your engine from blowing up inside. The 3.5 needs premium because it has the least chance of knocking because the engine has a high compression ratio. Using anything lower will only shorten your engine life.. So if u plan to keep ur car any longer than say.. 5 years..

I'm pretty sure that if somthing happens to your engine and it needs repair work, the delaership will test the fuel in your tank.....using anything less than the recommended fuel rating has the potential to void your warranty

[Giddy]

I'm Not sure they could void your warranty for not wanting to pay more for gas. That's like voiding your powertrain warranty for not putting full synthetic oil in your car.

So the 3.5 is only getting like an average of 4 MPG's less Hyw. and 2 MPG's City???????? Not bad for the extra HP

[{WBK}Viper]

I have a 3.5SE

22-24 mpg I do about 80% of my driving on city streets.That's when I'm not being a lead foot. and with full air conditioningblazing in the 100+weather.

If I'm being a bit more lead footed and trying to have fun itdecreases to 21 mpg.

[NissanAltimaGuy]

19 city if I'm easy on it. I'm usually not so it's about 18.

I've only been on one trip and got 29 highway.

[AltiCoupeFan]

My 2.5 has over 6000 miles and I average 31.2 mpg in hilly highway driving here in the South Central Mo. Ozarks. Now I will admit I keep it on about 2000 rpms as much as I can and avoid hitting the accelerator going up hills. When I want to have fun on the curvy/hilly highway I can get as low as 26mpg. I use high octane as it cost the same as regular unleaded here where I live. These miles were with the air on.

[nogears909]

2.5 with intake and exhaust and 18" rims and i average 28mpg with about 75% city, 25% highway

[Giddy]

Man we got MPG ratings all over for the 3.5 From

22-24 an city driving and 21 when having fun Down To

19 when easy and 18 when not?????

What are other peoples actual gas milage with the 3.5??? Miles per tank????

[{WBK}Viper]

I get anywhere between 405 - 440 miles a tank under normal80% city street driving, but I usually fill it upafter about 375 cuz the warning light comes on, but I always have moregas than the computer says.

[iiiskylll]

2.5 S CVT I get about 22-25mpg 60%hwy 40%city. But I speed like a mofo on the freeway so that explains it. I avg around 440 miles per gallon.

[packerjd04]

I have a 2.5 and according to the computer... Most of my driving is around town and i get 25-27 usually, and on highway trips i have gotten 30+.

[anthonyle2002]

i have the 3.5 and i get around the upper 24 since i always drive with cruise control on the highway

[CoupeSlate]

im getting 19mpg and around 23 highwayaround 90% is city for meive never used anything less than premium gas in mine:biggrin [excluding the first tank the dealer gave]

I read another thread discussing gas mileage and it seems the hwy miles are almost identical and sometimes surpassed by slow, steady driving in a 3.5 vs 2.5. Where the big difference comes in between the 2.5 and 3.5 seems to be in the city. I think with your good driving record and 25+ age, if you were doing mostly hwy driving, the 3.5 wouldn't be much different than the than the 2.5. But it seems to all depend on how you drive, where you drive and cost of insurance that needs to be factored in (also, wheel size and width).

I have a 3.5 CVT with 20's and a Injen Intake....Here's my stats

Non Lead Footed City......22.3 MPG Highway......27.8MPGLead Footed City......19.6 MPG Highway......24.7MPGDriving Ratio City......75% Highway......25%

I got these numbers as an average over a 7 day period. This was with the use of the AC 4 of the 7 days and with 85 Degree temps and high humidity. I average about 360 miles for a 17 gallon fill up.

I don't think that is true. If it's recommended I don't think it voids it. It's only when it says it's required that it may affect the warranty.

[altimacoupelvr]

I have the 2.5 CVT and I get 27-28 MPG City and 36-38 hwy!!!! But I use cruise control a hell of a lot!

My dealership told me they put regular in when the car was delivered to me and I did not have to use premium gas. But I still use premium.

[Sarcanglk]

I think there is something wrong with my car I don't know the breakdown of average for highway vs city but my car says I average 20 mpg... what would that be like 23 highway 17 local...
