[Yaris Mileage]

Speed is a big one...you'll get much better mileage around 60mph than 75mph (lower RPMS = better fuel economy). Maintenance is also big, but it sounds like you've got that covered.

A few things:

Temperature is a factor if you're constantly running vehicle accessories like heat or a/c. If you keep windows closed, especially at higher speeds, you'll get better aerodynamics and better mileage. Don't haul a lot of stuff around in the car...less total weight is better. Make sure your tires are properly inflated.

Before I purchase my 2001 Echo , in June of 2000, I researched all I could. Consumer reports showed that long term road tests in cold weather regions proved to shave off about 4 to 8 mpg off the estimated.

I remember driving my echo home from the dealer just over 250 miles on a 1/4 tank. I still average around 32/34 mpg, even after 198,000 miles. I have been very happy!

When I took the baby stroller out of the truck and the car seat out my milage went back up to around 36/38, Amazing what a difference that makes.

[2001 Echo 1.5 ltr engine code 5S-FE LPG/CNG Conversion]

Does anyone have information, links, ideas about where to find, if it exist, a coversion kit for the 1.5 ltr 5S-FE engine? I want to convert my 2001 Echo to CNG or LPG. There seem to be many coversion kits available for toyota's but they all seem to be for the larger 4cyl 1.8ltr or v-6's.
