Howdy all.
I'me a new group member in here.
Not new in the quest for mpg though and for many years (not so much recently) experimented with various ideas.
Some of my success are..
A '72 Fiat 128 with a 1100cc engine that made 100hp and gave 40mpg around town.
And a 72 KE20 Toyota Corolla that did 60mpg with standard power (maybe a little more but nothing note worthy).
This was in the pre-efi days and tuning done by gut feel and observation.
No dyno's , and nonoe of the diagnoistic magic machines that are available now.
I am sure that if I got serious about it now days that it could be interesting but the economy of my unaltered Suzuki Swift 1.0 is not demanding enough for some mod's - mind you I do miss the 120mph top speed that my Fiat had.
What limited my experiments from ataining more mpg was the fuel itself and this is where I would pay attention to and make my own brews.
Mechanically the cars can make great mpg , but its the fuel that is needing the change.
