I can't find my old message either, so I repeat
it below. I have continued to test mileage, and the
milage without the spoiler remains slightly better than
it was with the spoiler. Current average is 44.7 mpg
in mixed city/highway/hills driving.<br><br>Here is
the old post:<br><br>Answers to spoiler
questions.<br><br>1. To remove the spoiler, you remove the two bolts
that you can get to from the inside of the trunk lid.
That?s the easy part. After you?ve removed them, the
spoiler seems as firmly attached as before. There are two
plastic clips and some very sticky double-sided tape
underneath. Using a thin, flexible blade (an artist?s pallet
knife, which isn?t really a knife, works well) you cut
the double sided-tape. I did not find it hard to do
this. You can pop the plastic clips out, but this will
pull up the edges around the holes a bit. A piece of
wood to protect the finish and a few light taps of a
hammer (on the wood) straightens it out. As you pull up
on the spoiler, you can easily cut more and more of
the tape without risking the finish. I am a
do-it-yourself person who is comfortable doing this kind of
thing, if you are not comfortable, don?t try
it.<br><br>If you can get a thin pair of pliers to push in the
tab on the plastic clip, they come out more
easily.<br><br>I ended up with no scratches at all, and it will be
easy to put the spoiler back on if I wish to. You are
left with two rectangular holes and two round holes. I
am using the round holes to mount ham antennas, and
the rectangular holes are now covered with white
plastic, held on by waterproof double-sided tape which
makes them nearly invisible. If I make the change
permanent, I will have a body shop fill and paint the
rectangular holes.<br><br>2. I am asked how "scientific" my
results are with regard to drag. Not very: I do the same
kind of driving every day, kids to school (10 miles
each way at mostly 65 mph) some driving in town or to
nearby towns in the San Francisco area with lots of
hills. I keep careful records of gas input and have
found that the mpg registered by the car agrees almost
exactly with my own calculations based on gallons added
and miles driven. I have not calibrated the
odometer.<br><br>However, a change of 2-3 mpg would show up readily, and it
has not. My mpg has been essentially constant since I
bought the car, showing only a slight improvement after
I removed the spoiler, but that improvement might
be illusory. What I can say with certainty is that
removing the spoiler did not make a measurable decrease in
the car?s fuel efficiency under my driving
conditions.<br><br>3. Looks like an Echo.<br><br>I didn?t buy the car
for looks. My first impetus to remove the spoiler
came from seeing it in my rear view mirror while
backing up in my driveway and wishing I could see lower,
in case my 8 year old or her scooter were in the
way.
