I rarely ever shift above 2000 city, its very flat here.

And no I havent changed my fuel filter my car has 97K time for a change?

 

YES!!!! Geez, the most Id give a fuel filter is 40k MAX.

 

LOL! ok how hard is it? any write ups?

 

Not really hard. IIRC there is a nut on one end and a "quick" release on the other. Should take you about 20 mins on a lift. Search on here for a write up but not sure if there is one.

 

last winter I busted 30.1mpg all highway doing 75mph tires at 32psi

 

My MSRP window sticker says 20 city 32 highway. LOL for an A4

 

dont forget the gas has a play in it. within reason, not every gas station is the same. without getting into what brand is better (in that aspect theyre all the same), it boils down to the individual station. you could very well be getting **** gas from a particular station. it could be watered, lower then posted octane, old, dirty with sediment, etc. have you tried switching stations?

 

I get all my gas from the station on the base but have filled with others no difference ill try it again tho.....

Also checked my tire pressure....

DF-39, DR-20, PF-37, PR-32....I have adjusted all to 32Psi

 

Wow, 20 PSI. Thats pretty low. Id check it in a couple days and if its down 4-6 PSI take it to a tire store to get it checked out.

 

Went to the strip and took some air out and didnt put enough back in no tire gauge...lol

 

I got 17mpg 65mph cruise control on... Car has 115k miles. I seafoamed it and barely any smoke came out. Hopefully once i get my cooling issue taken care of i'll do an oil change, spark plugs, etc.

 

Changed the fuel filter today...ill see how the mpg tommrow!

 

I shift 2k-2200 constantly. And skip gears a lot since the gears are so close sometimes. Meaning I got from 2nd to 4th, 4th to 6th. But went the whole way at pretty much 75mph in 6th gear, just a few shifts to 5th because a few hills were too steep for 6th.

Some of those numbers sound off to me, but I'll take your word for it.

I go to the same 2 gas stations every time I fill up, depending on which one has a bigger price difference. My uncle goes to the same one's for his Z28, and he has never reported an issue, so I'm fairly confident this isn't the issue.

BBall, haven't changed it for almost 100k miles!!! WOW! Hope you don't frequently run your tank low before filling it up. Fuel filters are VERY easy to do yourself, I'm getting ready to do my fiances mustang again today. Takes me 10mins on her car, about 20mins on mine.

Glad this thread has brought lots of replies and tips, and new issues from other members. Keep it up!

 

NO!!! Mine was changed almost 10k miles ago. Ill never let a fuel filter go longer than 20k miles. Its so easy and cheap to change its not worth it letting get much higher than that. The guy I replied to was the one that almost has it at 100k miles!

 

Yea it was me I just got the car not too long ago I changed it yesterday took me 10 minutes and im pretty sure it was never changed.

 

LOL Sorry about that, i replied from my phone and got the names backwards since it didn't all fit nicely on my screen.

Anyone though able to reply on the theory of MAF position? Or anything else I or others can do to try and improve MPG? Guess it isn't to expensive to order some NGK's and MSD Wires. But was gonna wait for header install to do those.
Anyways, take care all!

 

The only thing I can figure about the MAF is there is an arrow on top on the black strip and I would guess that would go direcetly at the top because that would make the bar in the MAF vertical

 

Wow great find today...LOL...i had my friends read my codes and it said intake air temp sensor the one that plugs into the lid...so im like okay....look in the lid where its suppose to be and its not in there just the connector no sensor in it.

So i replaced it could that be my bad MPG?

 

It could be, that cheap little damn sensor wreaked havoc for me on my Formula for the longest.

 

What effects did you see when yours was bad?
