What MPG are you getting at 70 mph?
Andy
I do around 41.7mpg doing 70 on the freeway.
I'm also in Minnesota, and regularly drive down I35 at 70mph. I have a manual transmission.
In the late summer/early fall I was doing about 40-41mpg, with the factory tires. Two weeks ago, with winter tires (aired up to 50psi) and with temperatures at varying between 5 degrees and 20 degrees, I was getting about 38.5mpg.
Like others have said, the car is great for around town/lower speed highways. I wish there were a higher gear for interstates.
I'm getting 39 - 44 mpg US with cruise set at 110km/hr (68.35mph) in temp ranging from -5 to -25°C on winter Dunlops with my CVT.
Added Note: I leave the air cond. in auto mode so it's pretty much always on even in winter.
I have my tires at 35 psi all around. Still on the stock Enslaves. I average between 39-41 mpg according to the gauge. I usually average about 270ish on a full tank with commute averaging around 70mph. Not bad considering the high amount of traffic going through the cities + the cold weather.
I live in Florida, my tire psi is about 34 and we always have AC on and the tempature is about 80-90f I get 34mpg driving 80mph on the highway and some local driving. 260-270 miles per tank
Freeway/Interstate travel is the Mirage's mighty downfall. MPGS plummet due to the idiocy of not having a 6th gear for 70+ cruising. I can document 39-41 mpg at 70+ speeds, 80k miles worth. With a 6th gear, I'm convinced my avg would be a solid 5 mpgs better
Do you have a CVT or 5-speed? My 5-speed rarely sees over 60mph...lol. I can't imagine this thing at 80. That would have to be around 4,000 RPMs in a 5-speed car? :eek:Quote:

If you are driving the same gear, the crankhaft will turn exactly the same numbers on a given distance, no matter the speed or RPMs. Itīs only a question of the design of the motor, if this would be harmful. It may be better than driving with 800 RPM all the time... ;)
A taller gear won't overcome the additional aerodynamic drag of increased speed. When it comes to fuel economy, speed kills.
Don't you mean "drag kills"? The Aerocivic guy said his car could potentially go crazy fast(relative to its funky look and 'puny' motor) due to how little drag it generated. Granted, drag/resistance increases relative to speed, but we could cheat that a bit with a more streamlined car, right?
I have a brand new 2017 5 speed. Should i be avoiding 70 mph for break in? At 70mph i'm getting about 41mpg so it still seems good.
Texas the speed limit IS 70mph so it's hard to do less. I've hit 75, but not 80. I'm not used to being at 4k for 80.
No, you're fine. 4K is torque peak for the 3a92. I don't think you have anything to worry about. I'm not a huge fan of 0w20 oil. If you look at viscosity values at 100C compared to 5w30 there is a huge difference. It's why I switched with no loss in MPG's and the valvetrain has way less "sewing machine" noise lolQuote:

It revs very low relative to the manual trans, but it doesn't sound like I'm getting any better fuel economy even though my engine is revving lower. I seem to get right around 41 miles per gallon on the highway doing 65 to 70mph. The Nissan Versa I traded in actually got better fuel economy than my Mirage. 44mpg at 70. It's a bigger car with more power, so I'm rather disappointed with the highway fuel economy in my Mirage. It's definitely best suited for around town driving, where I averaged 39 - 41 miles per gallon.
I'm hovering at about 50 MPG at 70 with my current aero setup. Manual trans.
That's pretty good. I don't think I could do that.Quote:
