My little air dam has paid off I got 3.7L/100km on my last 500+km's
Getting to know my route better and leaving extra early so I can drive a little slower has really helped.
I can shut the car off sooner for downhills and stops, now that I know when their coming. So far all i've done is replace the alternator,because it died, installed new sparkplugs(copper) removed the excess interior, and installed an air dam. I posted about my simple air dam
here. I only yesterday found the time to take the mirrors off. and I still have a heavy trailer hitch attached to it! Lots of room for improvement. Oh I almost forgot its misfiring because the distributor cap is worn. I can't wait to see how it does when it's running right.
