Hi, I now drive a 93 Geo Metro GSi.

Previous vehicle was a 2003 Safari Van @ 18 mpg.

I am the second owner of the GSi, the previous owner was a lady who babied the little 2 door coupe.

The Canadian Metro GSi uses the Suzuki L4 1.3 motor.

I curently estimate fuel consumption at 48 mpg (US Gals).

This is really good and it has been checked over 10 fill ups.

Years and years ago I drove a Austin Mini with a 850 cc motor and I don't think it ever gave as good a miles per gallon as the Geo Metro.

I want to build the MPGuino fuel monitoring computer system so I can cruise at the most economical speed etc.

Also I want to fit a aftermarket cruis control for highway cruising.

My goal is to get over 50 mpg from the Metro.

Welcome to EcoModder! That's definitely an attainable goal.

Best of luck!

Welcome on EM.com

If you have 48 mpg then 50 should be rather easy, except if you eco-drive without knowing about it

With :

• a few tips from 100+ hypermiling / ecodriving tips to increase gas mileage - EcoModder.com (lower steady speed, driving without brakes...)
• and some chloroplast sheets tapped following 60+ Vehicle modifications for better fuel economy - EcoModder.com (front grill block, rear wheel skirts...)

you'll easily get a 10-20% improvement.

But with cold temperature you may have difficulties to maintain your current scores if you do short and/or city trips. See http://ecomodder.com/forum/showthrea...cold-5767.html

Don't hesitate to ask questions,

Denis.

Thanks Denis,

In SW BC Canada the temp never gets that low.

I am aiming at 50+ MPG without too many modifications.

Curently I have,

Replaced the spark plug leads.

Replaced the spark plugs.

Modified the air filter as per suggestions.

Increased the ignition timing 3 degrees to 7 BTDC.

Use 5W 30 oil.

and planning on new tires etc.

I am not sure what else to do to the motor to gain the extra 2mpg's I am looking for.

I cruise at 2,600 RPM which gives 60 mph on the speedo.

I short shift on the 5 speed tranny and do not reve over 3,000 rpm in the gears.

I seem to have one small issue with the motor which is when the engine decelerates it does not drop immediately to its idle rpm it seems to hang at approx 1200 rpm and then slowly decrease to the idle of 750 rpm.

I am still investigating this phenomena.

I am planning to purchase a 4 wire oxygen sensor to replace the one wire sensor, I read that the 4 wire sensor with built in heater gives more accurate control.

I will keep you posted as soon as I hit the magical 50 mpg.
