I did use the kill switch a couple times during the commute, but not enough to total a 5.2 mpg gain.


I wonder if a broken exhaust greatly affects mpg?

**SIDE NOTE: I discovered there is a rear sway bar installed too!**
The exhaust will effect mpg.

However...

You'll be surprised how much is saved with that kill switch.

10% is easy. 55.6 mpg x 1.1 = 61.16mpg

Shut the engine off when ever possible. You can easily bump start in 5th gear as slow as 5-6 mph.

Add a remote start switch also.


You should add a cardboard engine blanket to your list of mods. It costs nothing, shortens warm up and retains the heat in the engine bay so the car does not drop back into open loop when parked for short periods of time.


The little things add up.
