An update.
At 8488 miles I have changed the oil, switched to a K&N drop in filter and adjusted air pressure to 38 front and 36 rear cold. I also removed the rear seat since nobody is ever in it. It weighs more than I expected, probably 80-100 lbs for backrest and seat together with seat belt assemblies.
The car is factory otherwise.
I had a baseline average with usual driving habits on the same route in the same weather of 31.6mpg.
After a tank of fuel my new average is 34.4mpg
I still haven't changed my driving habits but I don't speed either.
For those interested in knowing what tires I use, they are factory installed Continental ContiSport2 225 width i am not positive the aspect but I believe 35 on an 18 inch rim. They are not eco friendly tires but do roll well.
My next mods will include a coroplast of the underside towards the rear and removal of the high rise rear wing, for both weight and efficiency, though is it possible the wing helps?
