Well I usually use Shell 87 octane all the time. I actually just bought a
Techron 20oz bottle of fuel system cleaner and poured it into my 17 gallon
tank full of Shell gas. I don't know that two tanks with the Techron would
be a good idea but I think in one tank it should clean it well.

As far as my driving habits, I drive 7.5 miles to work and 7.5 miles back,
most of it is highway going 55-60 and then the other times I am driving on
city streets doing 25-40 mph. About 50% for each, but still my combined mpg
is about 22 mpg and thats with AC and occasional cruise control. I have an
automatic accord ex and I sometimes use D3 when in the city. This is based
on my average weekly mileage of about 200. My car has 36,700 miles on it
right now and i change the oil about once every 6,000 miles. If I do some
drag races or aggressive driving my mpg is around 16 mpg.
