Newone with used metro

I just found this place a few hours ago. Hi you all!

After years of noticing them I bought a 95 3 cyl. metro with 5 speed a month ago. Darn that scangauge wont plug into a 95, going to have to trade cars. I just learned about scangauge today. My other car is a 2001 Impala LS with 3.8 which is amazingly efficient considering what it is. It has the computer and I usually get about 24 mpg actual commuting with it. The computer lies about 13% in GM's favour though.

I only get about 38 mpg with the metro. I think I am driving too fast, about 70 mph. From some graphs on the metrompg site it is clear I need to slow down. I am intrigued by good mileage and managed some impressive commutes with the impala. The computer display proved some things about my driving habits to me.

I have fantasies of adding an electric wheel to this metro, but that may never happen. Yeah I spent quite a bit of time on the metrompg page.

I have done a spot of tune up work to the metro. New airfilter. Iridium plugs and a new pcv valve. The old PCV valve was defective. I usully get real close to EPA numbers on most cars. That will be really hard with this metro.

Enough for now.

You can put a SuperMID mpg computer into a 95 Metro: see

Yeah, join the club. I've been thinking about that again recently also. Check out http://www.99mpg.com/mikesinsight/ to get the wheels turning even more (pardon the pun)

It will be literally impossible at those speeds. Of all the cars I've owned, the Firefly/Metro is the toughest to beat EPA numbers when driven "normally". Though it's got enormous potential if you slow down & use some unconventional driving techniques.

Don't forget to fill out your garage info. Plug some tanks into your Gas Log and start playing the game. Post a pic or 2 of the car in your garage profile. And have fun! Welcome aboard.

Welcome to gassavers!

I have heard that it is hard to make the EPA on metros. Team swift has a lot of information on there fuel economy section (I don't know if you have ever been there). But don't leave here because I am giving you a link

Teamswift can be great. I visit it regularly and post once in a while (a lot of repeats of topics here, often seeking Suzukiclone-specific feedback).

But I find people here have "the bug" for FE more than there. GasSavers is hardcore, man!

There's more encouragement here, and generally more activity to keep my interest in MPG percolating.

As stated, my driving at 75-80 was harsh on Metro Mileage (see my started gaslog) and in the end the Fit and Metro were about on par with the same driving style.

The GM 3.8 was a good fuel saving motor, not many know this.

I think the 3.4 is even a tad better than the 3.8 according to the EPA guide. The Impala coasts amazingly well.

My metro may need alignment or brake calipers. Something seems to drag even with high tire pressure. I have not had much time to check it out yet.

My first Firefly/Metro had slightly draggy calipers. I tried to service them, but it was a bit of corrosion on the piston preventing them from retracting fully/smoothly.

So I changed them with new/rebuilt ones. There was a noticeable difference on the next tank. Though from a cost/benefit perspective, I think I calculated the MPG gain would have taken 60,000 km to pay for the repair

Ime up for a big brake repair soon on my Metro Swift.

It will probably pass the next yearly inspection (next month) , but I know the discs are rusty , thin and scored (fins are hard on their brakes) and I think there is some drag in the front or the back.

So new calipers , master cylinder and wheel cylinders is on my shopping list.


PS , Not this sort of drag.

Questions about my 95 GEO. Sooty exhaust.

I tried slowing down a bit and it helped a little. I am only getting 38 mpg at best with my 95 geo 3 cylinder. No check engine light but the tail pipe gets sooty black. At idle it is not running rich.

What is the most likely thing to check?

I have replaced the cam belt and left the cam timing stock. I suspect at 103,000 miles the actual volumetric efficiency of the engine may not match the compter's expectations when open loop. I have tinkered with the fuel pressure a bit by shimming up the fuel pressure regulator cap. I suppose the the computer will just set a new base line at the reduced pressure but short term it might be helping.

Maybe the answer is to decarbon the valves and advance the cam a bit.

I had to change a half shaft seal and put one quart of ATF and the rest 75-90 gear oil in the 5-speed tranny. I have done similar before with no problem in other cars but am not recommending this. The second gear syncro works nicer, all the syncros do, and there seems to be less drag. Alas I need a scan gauge. That will force me to trade to a newer year. I know there are other options but that scan gauage looks like something I am going to own soon.

How do the syncros work with 0-20 synthetic in the metro transmission?

I was afraid the synthetic might be too slick for the old syncros. Maybe the lower viscosity offsets that.

In all likelyhood these items have probably been discussed at length. In that case I apologize and will spend more time searching next time.

Thanks for any insight.

Ernie
