Does running 20* give you better gas mileage?

 

i don't think that will hurt/improve gas milage. the advanced timing just changes when the air/fuel mixture is ignited. so technically the same amount of fuel is sprayed in, just ignited at different time. (correct me if i'm wrong though)

 

It says to "use premium fuel for maximum performance" on the inside of the filler door, so that might hint at what you should fill it up with... I always fill her up with premium

 

yes but Im pretty sure it burns it more efficiantly, I know my milage went up when I did it.

 

did it go up by a lot? i might look into advancing my ignition now

 

that was not at the same time you installed the flywheel right?


eitherway, cool, maybe i'll experiment with mine. (probably not though )

 

no I did the timing a few weeks ago, and the engine and the mods in august.

and yeah I would say another 5-10 miles pertank at leaat but its def. worth

doing if you run 93 anyway since your timing may all ready be retared a bit I

think D-sta's was a few degrees and Izzy's was mabey 1 degree mine was at 12 degrees but thats because the crankshaft sensor was swapped and the timing

not rechecked. But what did make the biggest diff, was the breather hose for

the gas tank, I would suggest everyone taking a look at theirs mine was rotted

bad, even if your not leaking fuel it may still be cause bad milage

 

wow, mine is bad and i get 14mpg.all stop and go in frisco. it's still better than the rx7-10mpg or less. suck fuel like crazy on idle,crusing or when trying to torque to reach upper rpm where it's fuel efficent, then gotta stop for traffic.

 

oops forgot to mention,breather tube that is bad was leaking then patch it up but it's still rotten.

 

its like $20 from nissan you are losing that much in gas milage in a month probably, just buy the hose

 

Different engine. The VE needs 93.

 

O2, O2, O2, O2, O2, O2.....

It's the FIRST thing to look at if your filters are fresh and you don't feel a miss.

The Automarket guy on here has NTK's for about $60 shipped. But any 3rd gen is now going to be in that mileage area for the O2 sensor to fail.

Injectors couls also be leaky or have a bad spray pattern, but if the "tune ups in a jar" don't help then you 'd have to replace them. THAT's not cheap.

Good luck!

My first three tanks of gas after buying the car were all highway and I was able to get more the 450 miles for each one. Around town I usually get about 250 mpt. I have a new O2 sensor to put in if it isn't snowing this weekend!

 

When you fill up, see how many gallons you're actually putting in. The Max holds 18.5 gallons.

 

Check your flex pipe in your y-pipe for holes. If you have holes in there it will suck air in and the O2 sensor will think that your exhaust is too lean and therefore tell the ECU to pump more fuel into the engine thus bad gas mileage.

THe O2 is 2 weeks old.

I will be changing the PCV and checking the Y pipe tomorrow.

 

Hey, can you give me a little more info on the breather hose? Where is it located? Where is the easiest place to check the hose for cracks????

 

i have a 92 5-spd and get anywhere from 280-380 per tank dpending on how I drive. Good luck!

 

Weird,how people mpg is so high when brand new i think it's like 19/25 mpg. oh 37 dollar hose, but removal of gas tank, i'm not incline to mess with old rusty every thing, and mech wants 300 for it and RUSTY is just too rusty for a new $337 hose.

What are you talking about??? You're not talking in complete sentences. What hose is $337.00?

 

37hose plus 300 labor for removing the tank

 

37hose plus 300 labor for removing the tank

 

What RPM should I be shifting at? I shift at about 3000. Is it true If i shift at a higher RPM the engine doesnt have to work as hard and I iwll get better gas mileage?

 

you dont have to drop the tank. and even if the hose is 37 thats still not that much

 

Can you give me a little more details on where its located or the best place to inspect the hose?

 

Umm if you follow the filler hose to the tank closer to the tank youll see another rubber hose (about 3/4" dia.) if the hose looks all cracked and dingy then it needs to be replaced, you can also start the car and see if you smeel gas by there. I can see if I can take a pic for you, let me go out to the car and see. brb

 

Really, the mech at 76 said Gas tank come off to access the tube on the tank side. umh, if no tank removal RUSTY might get $37.

Thanks,

my mechanic had the old hose off and the new hose on in about 5 minutes just need a long pair of needle nose plyers.

gjohnson I couldnt get a pic because of the low light and no drop light but I got a video with my nightshot Ill email it to you if you want

 

Could you send one to me aswell?

you know what ill just host it instead of emailing it to everyone

 

If possible send here Ruttrow2k@yahoo.com


Would autozone or pepboys sell this hose? Or dealer only?

Thanks

 

You still the man,

rymo.rymo

 

Man, I really appreciate you actually taking the time to do this. Yes, you can definitely email me the video or host it, whatever is easiest. Thanks again

 

Maybe this is the answer to all my problems. If so I owe you BIG TIME!

 

Im telling you guys it will deffinately help big time if your hose is as bad as mine was.

your gonna need to download the divx codec if you havent already http://divx.com/divx otherwise all you will get is sound

the movie is at http://jzullo.com/hose.avi

you may have to download it to view it

 

Is the clamp in the video the one your mechanic needed longer pliers to reach? I thought that was for something different.
Thanks Jay!

 

yeah and the one where it connects to the tank

 

I am getting 14.1875 MPG. THis SUCKS!!!!!!!!!!


HELP!!!!!!!!!!!!!!

 

did you read any of the thread? theres alot of suggestions in here.

 

I have read all of the thread. And I still have the problem.
