we love basjoos. I think of his aeromods all the time when I have to go to great lengths to get 70mpg in my stock unmodded VX. Unsafe tire pressures get me there, but ruin my tires too quickly. This spring and summer I've been getting mid 50s to low 70s depending on how I drive and the weather.
vehicle: 93 Civic VX
engine: D15B (single solenoid)
MPG mods: vacuum gauge
last tank MPG: 41
I was averaging 38mpg until last week when I installed a vacuum gauge. made a world of difference being able to monitor load and adjust my foot work. i installed it about 100 miles into the tank and got 41mpg overall. we'll see the next tank i should get more.. hopefully
Have run three tanks in a row over 50 mpg!!! These are my best tanks in this car, too. I think the car is now running in tip-top shape after having sat a while being worked on. Everything is broken in and running at optimal levels. I've had tanks averaging 51, 55 and 52 mpg. This little car is amazing!!!!
