i heard somwhere that the auto 2k2+ get better gas mileage on the highway due to its gearing than the 6spds. is this true?

 

No, they shouldn't. A manual transmission will always allow you to get better gas mileage. And without looking, I'd have to bet that the 6th gear on the 6 speed has more overdrive than the 4th gear in the auto.

Now, people may tend to drive the manual harder, which is a whole nother story.

 

lol cruising in 6th speed at around 65-70 gets me around 35-40 mpg... thats what mpg diplay told me i really doubt that an auto gets that... my average is around 24.5 mpgs and i drive 75-25 city/hwy and i drive pretty hard

gotta love the 6 speed

The epa rating for autos is less for autos than for manual. City driving is much less because of transmission slipping.

 

The display is wayyyy off if it says you're getting 35-40 MPG in 6th...

 

I know the most i can get out of 5/6th gear is 30-32mpg- I use 6th gear
alot on the highway and my mpg is climbing but 35/40

 

I can get 30-32mpg on 100% highway on my auto.

 

i dunno man if i push it hard it goes down to like 13-16 and then i was just kidding around and i got up to 70 mph and then put it in neutral, and reset the mpg, and it was showing 51 mpg
guess my car is special

-IgS, ill take some pics

 

in your auto, what's the rpm at 93mph?

lower rpm is higher gas mileage... at 93mph my 6-speed is turning 3k rpm (exactly).

 

Not sure here, but i can tell you 80mph on my auto is 3k rpm.

That is, until i switched to lower profile tires.

 

so that seems to me an auto should get lower mileage and the stick should get higher mileage.

right?

 

yup just like i said, if he is saying that he gets 30-32 mpg on auto while his rpms are higher then a 6 sped should definately be able to reach 35-40 mpg.....

 

My rpm is roughly 3400 when im at 80.... So i guess my question is why do manauls get better mpg when our engine rev's higher at those speeds?

 

Yep.

If anything, i think it has a lot to do with driving style. Though i'm a pretty aggressive driver at times, if i really baby it - 30mpg is not impossible at all.

 

lol lower rpms=more miles per galon.......

 

For all the mods i that have invested into going faster, i'd probably average at about 25 mpg wide open throtle on highway run. It's suck gas but it's fast............LOL

 

While my mileage is terrible in rush hour, usually getting no more than about 20-21mpg, my auto gets great gas mileage on the highway. I usually average around 31-35mpg while driving on the highway. This is actual mileage and not the cars computer which is consistantly 3mpg off.

 

You must have been coasting downhill.

 

Are you guys serious? I would love to know how a 3.5 Maxima is getting a real 35-40mpg highway.

IMO NO WAY!

 

......

 

if that is the case, AGAIN, why do manuals get more mpg when our engine rev's higher... you didnt answer my question..

 

this question was answered 3 times in this thread... because at the same speed, A MANUAL ENGINE REVS LOWER!

my 6-speed is turning 3k rpm at 93, his is going 84 at 3k rpm.

so, if he speeds up he'll have more rpm and get less mileage... or if I slow down I'll have less rpm and get better mileage.

 

34mph at 91mph all the faster the cruse will set at
