I've searched around a bunch of forums including this one. What's the best anyone can get out of the 1.3/auto mostly highway??? I've seen people say between 30-40mpg. What about people who actually drive on highways @ 70mph or so? Would these car suck that bad because of the three speed??? I'm in the market for another car to replace my 'Tour something a bit smaller but want better mileage. I commute 130mi a day for work and manage to squeeze out roughly 30+mpg in this car driving conservatively. I know these cars have a good reputation and might have found one I like but Auto. I remember an old K car I had that was a 3 speed auto and was fine on the highway, might've had the lock up TC though. Any input appreciated.

It really depends on how well the car itself runs, and the driver. I'd say I would get about 30-34 mpg mixed driving, highway, probably would be around 32-36 mpg depending on speed and driving style and so on.

The manual will get substantially better MPG, and if I am not mistaken, has to do with having not to do necessarily to do with the extra gears, but rather the nice 5th speed "overdrive" gear.

Personally, I am looking forward to getting a 5speed on the road.

130 miles a day!! i don't even put that much on my car most nights delivering! a friend of mine was doing about 150 miles for a while, it turned out to be more economically feasible to take a small pay cut to work closer to home.

i don't know what gas prices are where you're at but here it's about 3.15/g at the cheapest place around. if i were traveling 130 miles at that price, getting 35MPG, i could take a 1.46/hour pay cut (working 8 hours per day) to work within walking distance and still make the same money. even in some of the cheapest places in the country you could easily take $1 pay cut and still come out ahead.

just something to consider.

I know it's a lot of miles to be driving to work, but I enjoy what I'm doing especially since family is envolved in the business. I do plan on moving closer to the business but for the meantime I have to hack it and save up to get a place closer. Gas is currently 2.50+ for regular, probably not for long, as anywhere else is more expensive. I'd rather commute to a job I enjoy doing rather than work 15 min from home and hate it(which I used to do). Well that's the story in short, I'll stop rambling on.

Gas isn't going to get too much more expensive, I don't think.

My Dad drives across SE MI, 57 miles each way. I feel for you.

I really don't think a 1.3 auto is going to help you much. The only way you can really lower your fuel bill is a 3 cylinder 5 speed.

The contour should do pretty well. I really like those cars and I think I'm going to try to find one.

.

I've got a 1995 1.3 auto Swift and from 2 tankfulls all right to the brim
I have been getting around 33-36 mpg US.

The last fillup was 358 km @ 25.671 litres which is 32.99 US or 7.17l/100km. Most of this driving was at 120 km/hr mixed hwy and city.
The most recent fill was 437 km @ 28.21 litres which is 36.65 mpg US or
6.46l/100km. Most of this was hwy at 110 km/hr.
Both runs were with tires inflated to 50 psi. , oil changed with dino 10w30,
old plugs, old 02 sensor, new air and oil filters.
All in 20 C weather.

There is quite a difference with the higher tire inflation.

on my 4cyl auto.....30-38mpg....depending....
best ever...40mpg, but that's NOT the norm...


The 1.0 gets 40-43 w/o propane injection.
If I run propane, I get 45-47....

wow, what the hell am I doing wrong?!?!?!?! my 94 metro with a 2k 1.3/auto gets only like 27mpg and I mostly do nothing but highway at about 75mph. (anything less than this and I can't sleep in :lol: )
Damn I should've kept the 3banger in there :(

You need to get propane injection! ;-)


You'll pick up a few mpg AND a few HP w/o having to use premium fuel.

Try slowing to 65-70 and raising your tire pressures. :wink:
Also make sure the thermostat is a 195 degree unit, and check your spark plugs.

Plugs/wires are new, will try the tire pressure trick. How do I check the thermostat temp? (and the 65-70 is pretty much undoable, I'm just not a morning person :lol: )

If your temp gauge sits dead in the middle, your thermostat is good. Tires up to 35 - 40 psi will help, but your problem is rpms. At 75 with an automatic, you're turning the same revs as a manual at 100 mph. If you want mileage, slow down, if you want to sleep, you'll pay.

Yeah I kind of figured as much...although here's a short list of what I'm assuming is fudging my mileage:

bad o2's (car sat for 3 years)
totally fudged exhaust (rear ended by a pontiac montana and all that was damaged was the exhaust :lol:)
horrendous alignment (rear toe-in is terrible due to the mk4 trailing arms being ~1-2in longer than the mk3's)

I'll post back after i get all this shite fixed first!

About once a month I drive from Dallas to Austin and back. About 300 miles one way. I have been playing with just mph I do this trip at, and have the following results for making this trip over the last year now.
60 mph = 30mpg, 3,200 rpm
65 mph = 35mpg, 3,500 rpm
70mph = 39.75 mpg 3,800 rpm
75mph = 33 mpg, 4,200 rpm

1997geo metro 1.3L automatic A/C 2 door (120,000+) on the odeometer
No P/S, stock exhaust.
5/30 mobil 1 engine oil (15,000) last oil change
Quaker State full synthetic ATF Dextron-III
P 155/80-13 Firestone tires @ 35 psi (cold)
Shell Regular fuel
197 deg. thermostat
Factory timing and distributor has been curved to factory advanced settings(on a distributor machine at the local hot rod shop)

I do fuel up at the same two shell stations that are right off the interstate every time. So no city miles between fuel-ups, And I dont overfill the tank. I stop at the 1st auto shutoff.
I have tryed using premium fuel and see no change in MPG but the car does run better at idle after using premium.
I do change the air filter and oil filter about every 6,000 and the fuel filter about every 20,000 miles.
The car is basicly stock. It needs paint badly and I did add an aftermarket tach. I did add an additional ground wire between the motor and the fire wall. And I have added a switch on the emergency brake handle to turn off the headlights. I also have added a round piece of cardboard to the hot air intake tube to block of the hot air coming in from the timing cover. Summer months only.
I have stayed away from runnng cheap fuels as they don't contain the additives that help keep your fuel system clean. Engine idle is ruff on cheap fuels.

In conclusion, I would say that if you keep your car well tuned and keep up on the maintenence, these cars are great on mileage.

this is one of the brightest posts I've read on here (and would have never expected to see) in a long time.

nothing more to add.

carry on.

OK, after topping out at about 300mi per tank, I think I'm going to swap out to a manual tranny. Anyone have a link or recommendation as to the best tranny to use for fuel economy on a 1.3?
I looked at gear ratio threads and THINK my understanding is that a 1.3 5spd would work out best for fuel economy and that a 1.0 trans would be great for "performance" because it has shorter ratios. My question is, does anyone know if the 1.0 ratio's are "better" than the 3sp auto? (forgive me if that's phrased wrong, I am a complete noob on the workings of auto trannies)

I'll have to agree with fainya on this one....
I just got back from Knoxville and did a little experimenting with my 99 4 cyl...It seems to get the best mileage going around 65-75mph.
w/o propajet I was getting 35-36mpg....going 65solid I only got 33-34mpg... now I JUUUUST put the propane on and it did the same to the mpg as it does in the 1.o....about 3mpg MORE to the gallon....


This was a 1300mile round trip for me.

I drive a 3 litre ford tauris, and at 100km (60mph) i get aprox 43 mpg.
One thing that you could try to get better fuel economy is to use a k&n filter, on my car it raised the economy by 2 mpg, i also added irridum plugs, and went with 8.9mm wires, and a performance rotor. also one other thing that helps is to install a taller tire size on the vehical, but be warned it will throw out your speedometer. reducing exaust backpressure can help as well, by installing a freer flowing mufler, but on some engines, they require a certian amount of backpressure, or the engine will not run properly. Just some suggestions.

I would have to add that the 3cyl 5spd really would make the most sense, if you don't mind shifting. Just put a 91 on the road for winter and went 585km on 29l. This was close to 20mpg more than the civic i was driving before. The 4cyl just doesn't quite offer enough gain over most other small cars(contours, neon, cavalier). The contour size cars just idle down the highway, where the 4cyl auto geos rev just a bit to high. A 3cyl would be the perfect commuter for your purposes. I would lean towards the 95+ models, they just feel solider and handle much better than the 89-94's. If you spend that much time on the road, you will appreciate a quiet ride! Just my 0.02...

this is a great little thread. I will definitely take the 65-70MPH cruising speed into attention for the 1.3 auto transmission. Later on, when the car is finished and I get another job I plan on adding a ScanGuage which gives real-time MPG readings. although, my mechanical abilities limit me to the basics so it'l have to be in a year or two which I may transfer the auto trans to a manual 5 spd.

It has been awhile since I posted to this thread. In that time I have replaced all of the wheel bearings and I used moble-one synthetic grease on all the bearings.(they where getting noisy, so I did them all.) Inner and outer tie rod ends and relubed the rack with moble-one grease. (inner tie rod ends where really loose) Installed camber cam bolts on front end to get better tire life. Four wheel alignment. New front rotors and pads. One $200.00 fuel injector. The old one just died one day. (open circuit).
Now for the good news...
I drove from Dallas to Houston and back this past Sunday. This is a 210 mile trip one way.
I got 38.4 mpg at 60mph going down to Houston. In houston I picked up about 400 pounds of machine equipment and loaded it into my metro.
I got 40.5 mpg at 65/68mph heading back to Dallas.
So with more weight I get better mileage? what do you all think?
Fyi this trip was done on cheapo gasoline!
Tire pressures: Front 40psi, Rear 35psi.

Like the fellow said, a scangauge will settle the issue.
Although bearings, tires, and alignment are the first order of the day...
I think your $200 fuel injector is paying for itself in added fuel economy.
Good post; not as good as your transmission fluid advice for noisy lifters (which most will miss), but still a good post!

I have added ATF to help clean out the engine before I do my next trip. After I get 500 miles on the car and do an oil change, I have another trip planned. It will be a 1000 mile trip and I will have a scan tool with me on this up and coming trip. I will post the results I get. I am looking forward to getting 40mpg. I am not sure if I will use cheapo gas or go back to using Shell on this trip.

FYI.... in town mileage has come up to 32mpg average. It was getting only 30 before.
