these are averages. I've probably done 23 hwy in the Jeep.


buying a prius next month & selling both of these...

Hope you are already on a waiting list, or already found one you want.

Time for some oldies. In the 80's I had a 81 Rabbit Diesel that got an average of 33 (mostly city), with a high of 46 on longer trips. My 82 Rabbit Gas got an average of 28 city, with a high of about 40 on longer trips. My 76 Datsun B210 got 35mpg on trips. It didn't have an overdrive. Technology hasn't brought any big changes in the last 25-30 years it seem.

Cleaner air (catalytic convertor and other polution controls) vs better mileage.

Don't forget all the mandated safety features and capability which add significantly to the weight. Luckily I drive the lightest car in it's class, the Ford Focus Coupe S, which is a shade under 2550lbs. Even the Sentra is ~3000lbs now! Jeeez.

I wonder if it's the safety features or just the wanted extra features that is causing the weight gain? With lighter materials (more plastics, aluminum enginer blocks and heads, etc.), one would think the safety features are offset in weight. However, with larger stereo's, power windows, power seats, on and on and on, the weight might have increased. Of course, SUV's skew the average weight of cars today because of their giant size to begin with.

28 MPG on the highway is the best I've seen. I average 23 MPG with about 60hwy/40city driving in my 03 350Z

 

[Svnla]

23 to 24 MPG is my average. I did everything I could to maximize it <speed limit, no useless stuffs in the vehicle, properly inflated tires, tuned up no idling, etc.> but still can't go much higher than the EPA gas mileage standard for my vehicle.

30mpg in a mazda3

Last fill: 38.34 MPG/7.3 L/100km (mostly highway).
Best: 41.41 MPG/6.8 L/100km (I dont know how I pulled this one off...it was 100% city driving).
Average: ~35 MPG

I am calculating these values just by plugging in numbers on gasbuddy.com. I find it strange that I am getting such high mileage when my car is only rated 22MPG city and 28MPG hwy. I dunno...maybe its my driving habits, or wrong calculations.

It is as simple as resetting your odometer each time you fill up.

mpg= Miles / gallons

example:

If you got 350 miles for a tank, and it took 12 gallons to fill up=

350 miles / 12 gallons = 29.2 mpg


Your mileage does sound high unless you are using some hypermiling techniques.

 

[OdiN]

I somehow got 38MPG once with my 97 Maxima. I still don't know how because I was going like 80MPH most of the time on that trip.

How the hell do you do that??? I drive good in my 97 civic and only manage about 34-35 in the "winter" with no AC and about 25 in the summer using AC non-stop.

Some of the mid nineties Hondas had lean burn similar to the Insight. Lean burn can give astronomical numbers. Normal cars do 14:1 air:fuel ratio, the Insight for example can do 25:1

Still doesn't really answer how the mileage is so different. Maybe I need a tune-up.

 

[BassBomb]

well i just checked again and I managed 35mpg 60/40 city/hw when on hw I was going 120-130km/h, but city was speed limit
i was somewhat happy with it

 

[thecoolnessrune]

17.5mpg in a 2004 Expedition.

 

[Crassus]

My recently deceased 2000 VW Passat Wagon (1.8T): best ever 35 mpg HWY, avarage 31 HWY, city with short trips 2 miles a trip down to 22 mpg.

Back in Germany the best I did was 5.4 l/100km on pure biodiesel (canola based) with a 1999 VW Golf Wagon TDI (PD). Too early for me to get a calculatur out

2006 Mazda3 Hatch, 5speed, 2.3L engine, 40psi tires, 95% highway driving
Best Partial Tank with small tailwind:
Miles....Gal....Price....mpg
------------------------------
186.0....4.47....2.859....41.6

Best over 3 tank average = 37.2 MPG (data below):
Miles....Gal....Price....mpg

186.0....4.47....2.859....41.6....12/17
389.0....10.82..2.909....36.0....12/18
348.4....9.63....2.989....36.2....12/22....oil change 12/19/07 @ 17980 total miles

Worst 3 tank average 26.7 MPG.
Lifetime average = 32.5 MPG @ 25,000 miles driven.

In one fill up? Like, reset the trip, drive all week, then fill up again and calculate MPG?

23MPG

Mixed hwy/city, '97 Nissan Altima GXE w/2.4L KA24DE

Reason: I'm 16.

EDIT: My Dad averages weekly, roughly 21-22mpg in his 2002 Explorer XLT v6. How IDK but I guess thats the advantage to working nights - no traffic + cruise set to 55 + coasting to redlights and such.

 

[cmf21]

Parents 2000 Buick Lesabre averages around 34mpg on the highway and my old 93 Dodge Colt used to average about 45mpg

 

[NaOH]

Not sure what I get currently all highway... But i recently got 30mpg, with about 33% highway and rest city.

1997 civic ex with bolt ons

A little over 33MPG.

Not too bad. That's probably about the best I've got in a vehicle.

How do you like your Mazda5?

My wife and I have a baby on the way and we have been looking at the Mazda5 as our family hauler.

 

[exdeath]

Cruising and saving gas? 25.

Having the most fun? About 8.

Same car.

Screw gas prices, I just spent $1200 on tires.

 

[onza]

31mpg in my 06 acura TL, 120miles hwy, @ 65-70mph.

Averaged 35mpg over 300 miles in my Mazda 3s. Had a nice tailwind. Usually I get 32mpg max.

i usually get 36mpg in my Mazda 3i automatic.

then i switched from the OEM Proxies tires to bf goodrich traction t/a.

great wet traction but at the cost of 2mpg.

now usual is 34mpg

Yesterday I averaged 57.8 MPG in my 240 HP Accord over 29 miles at ~55 MPH. Downhill, of course.

But the trip uphill over the same route was 25.1 MPG, giving me an average of 41.95 MPG round-trip.

That figure was verified by my GPS and pump calibrated ScanGauge II. That's my best round-trip score since getting the gauge. It's also a great example of how engine efficiency increases with wider throttle openings. I used the mountain as a "momentum battery," ran the engine harder filling up my "battery," then cashed in the momentum downhill, where the engine used automatic fuel cutoff to coast a lot of the way back down using no gas. The result was less gas burned than if I had simply driven the same speed at constant throttle over level ground.

I've found that with a careful right foot, I can average ~35 MPG over long distances, including up and down mountain ranges.

momentum battery?????

so you gun the gas going up hill and use little/no gas going down hill.

and that uses less fuel than constant cruise control???

that doesnt seem possible. gunning the engine = higher RPM. the higher the rpm, the less effieicnt fuel econ is.

78 mpg with a 1993 Honda CB250.
Slowest pile of crap I've ever had.
Real bikes...about 53mpg average on a DL650.
