Well i was talking to one of my friend that owns a rx-8. He said, he read and heard that the best rpm to shift at is at 4000rpm. So the question is now what is your opion on whats the best rpm to shift at and get the most gas milage out of our cars.


Ill start first by saying 1,500 and when around 40 to 50 keep it in 5th gear to make the conditions of high way travel.( 2,000 to 2,500rpm)



by the way typo on the mpg.

 

Accelerate slowly in each gear 'till 2000RPM and shift. You won't be bogging at all, so its fine for the car. By 40 you'll be in 6th @ 1400 RPMs (the manual itself says 40mph in 6th is ok). *Key* is gentle acceleration...results = 26-29mpg in city, which is attainable.
Nissan advertises ~ 20mpg in city. It's a no brainer that one can squeeze out a mere 6 or so *miles* per gallon with gentle acceleration, shifting at lower RPM.

 

wow, i never new that.(honestly) Does any one else has any idea from personal experience?

 

It's how you drive the car. Check this episode of top gear out.

PRIUS vs M3 which gets better gas mileage?

More importantly is how you get to 4000rpms.

 

it's impossible to get that mileage in an actually city.

Keep it under 3K rpm and use 6th gear as much as possible

 

 

Just drive the car! those extra dollars are NOT going to be worth it if you can't have fun!

Of course living in congested areas like LA will get you nowhere near 25+mpg in city. In my area, stop lights are every 1/2 to every mile.
Here's a post I made a year or so ago: There are also many other members averaging 25+mpg in the city and 30+ freeway.

This ride is as economical one could get. Gives you performance at decent fuel economy. It can be as good as a Honda Civic, given you drive it right. I Average 27-29mpg in the city; usually 470mi/16.7 gallons. Longest I've driven on the freeway after filling up was ~ 60 miles, averaging around 37mpg @ 60mph. Now I'm a bit above the 1/2 mark on the fuel guage and I've travled 210miles. Guage is reading 27.8; was 28.4 today but I was in the mood for some "spirited" driving :-D

I tend to shift between 2-2.5K RPMS when taking it easy. I stay in MD where it takes me 1HR+ to go 30 !&@*!ing miles. I get 21.6 MPG in the city and 27.0 on the highway at 80 with AC running.

 

Oh boy a MPG thread.

 

Oh boy another sarcastic remark from davidv on top of the 20k other ones

 

Lol, sarcasm is funny, as long as it is not used all the time

 

hmmm... i get 19mpg city... and i do light cruising.. are these averages for NA motors only? no matter how much i try, i cant get over 19mpg... i usually average 240miles for a 13 gal tank (never did the gas hose TSB so i cant fillup tank all the way)

 

Did you buy a Z to worry about gas mileage? I didn't.

 

when i bought the G, gas was under 2 bux a gallon, now I'm paying 4.21 a gal. big *** difference if u ask me. i dunno about you all, but i like to get the best bang for the buck...

 

Of course, gas prices are nuts. I pay 3.89 here. When I bought it, I was paying around 3.00. I love the car and the extra 20 or so dollars a month doesn't phase me. If you're worried about gas, maybe it's time for a Yaris!

 

I get 21.9 in the city in my Z and I drive enthusiastically.
