Am I the only person who regularly puts 16 gallons in my FC?



FYI, the low fuel light comes on with 2 gal usable left, and the S5 tank has 1 gal unusable.

When I first got my car, I was driving it like I stole it, and I got about 12 MpG. Since I have gotten up to about 18-20 just from a change in driving style.

Driving style and number of cold starts / warm-up cycles seem to affect the MPG I get out of my streetported 87 base. I average 20.

i went over to nicks house, APEX13B to help sell his car to mah boy , and upon inspection nick said that the thingy that opens the 6 ports after u hit 4k or so was stuck open, i guess thats teh problem why my **** is terrible, i just filled up my gas tank last night and filled it up half way, and from 1/2 of the 1/2 tank i got 60 miles so if this continues then im getting 120 miles per half tank and 240 for full tank which isnt bad, i changed teh plugs yesterday, cause they kept getting fouled up, and if im running rich how can i change that to get it just right?
