If you have the hood up, with engine off but the fuel pump forced to run, you will here the fuel woosh.

Ok, I'll check on that for educational purposes.

I've used a few fuel treatments and haven't seen any correlation between that and mpg, although that's not specifically what I was looking for.

Like? I went through a pretty extensive list in the first post of what I've done.

Things seem to be looking up! My last three fill-ups have been:

1) 13.224 ga @ 243 mi = 18.38 mpg; changed coils mid-tank, ~1/2 highway
2) 15.817 ga @ 290 mi = 18.33 mpg; 1/2 to 2/3 city
3) 6.893 ga @ 157 mi = 22.78 mpg; mostly highway, several stops; a few hard accelerations

The significant change was finally swapping out ignition coils -- they yielded inconclusive results when testing them. When I had the exhaust work done, the guy said it sounded like a misfire. Turns out he may have been on to something. Replacing the coils eliminated the last of my hesitation issues, and mpg seems to have immediately trended upward. I still have to see where it's at for a tank of just city driving, though.

24+ mpg does look achievable on the highway. I'm hoping it stays in the 16+ mpg range around town now.
