Hello fellow eco-modders!
I've eco-modded a 1999 Mazda Protege with smooth wheel covers, air dam from a chevy truck, upper and lower air blocks (drilled some small holes) and went from 26 mpg stock to 36mpg. Have adjusted nut behind wheel as well.

Noticed large American trucks now hating me. Max. MPH now 50.

Wanted to say hi and stop being a lurker. I have a new appreciation for this car. Also took spare out of trunk and replaced it with two cans of fix a flat. Full 5W-20 synthetic Castro oil. Next: side lower rocker panel covers. Other ideas?
