2006 Civic EX sedan
 

Just wanted to make an account here finally and introduce my semi-eco honda civic. 2006 EX automatic with 160k miles. I have made the modifications to be the least noticeable as possible, while having any mod be reversible as well if I want to sell the car. Wife likes AC and also insists that anything radical is not allowed, so no big aero things.

I have improved MPGs significantly over the ~3 years I have modded, and recently got 51mpg driving from Denver to Fort Collins quite aggressively (max speed was 86). Tanks are usually 34-42 mpg mostly because my daily commute is 3 miles in town. Town and highway driving is usually speed limit+3mph and has been ~45ish until recently where it bumped to ~50ish. The bump happened after a few things including chevron techron cleaning, small aero mods as well as turbulator tape. Even though I'm a scientist I don't do ABAB testing like I should.

I've learned alot using this website and would like to thank everybody.

Eco Mod List:
- civic hybrid lip spoiler
- downsized & lighter 15" wheels with eco tires (conti pure contact at 40psi)
- removable grill block, block heater
- partial undertray
- replaced all but headlights with led
- 2 watt solar panel to try to keep battery topped up when shut off
- aerodynamic air diverters? trying to smooth flow around wheels
- scanguage e
- turbulator tape (not sure if this is doing anything)
- sealed lots of gaps in bodywork
- removed mud guards

Non-eco mods:
- black stripes on front bumper which covers a dent the previous owners made.
- sound deadening material added to interior/engine compartment
- clown car horn replaced with accord horn

Welcome out of the closet


I've used thin dimple tape on my previous car (A-pillar , mirrors)
Certainly altered the flow over the side windows and quietened the mirrors


Didn't do bugger all on the squarish rear end though - the dimples (or tape)being too shallow for the thick boundary layer there, I'd guess

I have definitely noticed less wind noise from the mirrors as well. I put some on the rear end and it is likely not doing anything, but I like to tell myself its helping in some way.

Wife just noticed it this week and I got the typical eye-roll reaction
