does the z32 only take premium gas?

 

Yes 93 octane or higher.

 

what state you live in?? 91 is the highest over here

 

well, always the higher the better (until 105+ when it becomes leaded and starts to kill catalytic converters and O2 sensor), but Riz and I are fortunate enough to live in Illinois, where 93 is common and 92 is about the lowest "premium" you can get =D

 

yes, absolutely, no exceptions. the gap between regular and premium has closed quite a bit since the prices started going up, so its not as big a deal anymore.

 

what is your guys' plus? ours is 89 and premium is 91. I'm hoping that your plus isn't 91, or us cali folks are basically having to go with plus in relation to the standards that Nissan meant when the Z was being produced.

 

no, it's 89, don't worry

most stations have 87, 89, and 92 or 93

 

i dunno about the turbo guys but i can tell the difference between 92 and 93.
I'm not saying it's Night and Day difference but i can definately feel the difference in response and acceleration between the two. Don't ask me to explain it, i'm just telling you what i've experienced.

 

actually, You can get 100 octane that is 'low lead', so u still need to be careful and check.... I live in AR... we have 87,89,91, and 93. I've run 95 or 97 though ( can't remember which).

 

Isn't there an additive you can get that will diminish the lead in race gas?

 

ive heard of a guy who ran the 89 in his NA. he says it ran fine.

here the premium is at 91 in some stations, and 92 the highest in others.

and also i dont know about you guys, but one day i filled my car up with cheveron gas, then it ran like anus. ive usually put shell in mine. it was both the same octain at 92. any opinions on that?

 

You don't need preminum, you need the lowest octane rating that does not knock. Does that make sence, do I have to explain it better ??

 

No, That makes sense and you don't need to explain it further. That's the truth guys. Extra octane is wasted for the most part. Run whatever you can without knocking and pinging and you are fine. I was running premium only forever because I thought I had to. My favorite station was out of premium so I put in the mid grade and noticed no difference in the car at all. Then I figured I could get away with regular... Wrong. It ran very poor on regular but was awesome with the mid grade.

haven't you ever heard of "better to be safe than sorry"? I'd rather have the extra octane points and not need them, then need them and not have them. For example, if I know 91 octane won't knock on a 70degree day at my usual 17psi, and I boost 17psi on a 95degree day, it's probably gonna detonate. With 93 octane, my car has never detonated at any of my boost levels, and therefore I stay with 93 octane.

Not to mention, 93 octane costs the same as 92 or 92 octane here, so if you're gonna pay $2.45 for it no matter what, might as well get the stuff that protects better.

If conventional oil and synthetic oil both cost $2.00 a quart, and you knew that the conventional oil would work fine until your next oil change (keeping in mind the ONLY advantage that a same weight synthetic has is a longer life, which doesn't matter with regular oil changes) would you buy the conventional oil because it'll get you by just fine or would you opt for the synthetic oil that will protect longer even if you don't need it to (because you change your oil frequently anyway)?

 

WOW, slow down slick. I did not mean to sound arrogant or anything. I was seriously asking because not everyone knows about this stuff. Apparently you do, the person asking did not. So, no offense to you or anyone else.

Zlover, that is true, better to have those extra points for safety.
O/T what do you use to tune??

 

I didn't think he was upset or excited or anything, just agreeing with you.

 

werd on that one, especially at the higher elevation (at 5000ft. it is pretty noticeable, even to the extent that my car runs better at night because of temps.)
If you ever come up here and see some fast cars, just imagine them at sea level.

sorry, didnt read any of the other posts....too long of a thread for me.

 

one page? It's barely onto 2 now.

 

Dude, I'm cool... I was actually just backing you up and letting you know that I agreed with you. Don't sweat it. Now, for guys with built motors and high boost applications, draw your own conclusions. I agree it's better to have it and not need it than to need it and not have it. It certainly won't hurt to run higher octane than you need.

Did I sound pissy before or something?

Sorry man... just agreeing with you was all

Rod.

 

You don't need to run 93 octane at all. All that is called for is 91. If you can run on 89 then it's fine. There is nothing to worry about if you dont hear or feel any knocking or pinging. Running 93 octane is just a waste of your money. You're not doing yourself a favor by running that high of an octane.

 

This thread is getting REALLY repetative! I think I've read the same essential post 4 times in a row now.

 

Rodmoyes, It is hard to tell peoples real intent sometime, I guess I read it the wrong way. I aplologise to you and any others.

But back on the premimum issue. Stock cars are set up to run on the lowest available octane. But you also have to remember that for the most part, people are not really into their cars. So if Nissan didn't put that little sticker on there, some people would try 87, cause it is cheaper, they just don't understand the whole engine thing. And there service bays would be full of people complaining, about how there new car runs. And they would have lost there a$$ to warrenty repairs. That is why Mazda pulled the rotary out of the U.S. They literally lost millions to warrenty repairs, not because the rotary is a bad motor, it just takes more maintenance and a closer eye to what the car is doing. And your average Joe Smo, does not understand that. And the lower octane thing does not work on all cars. There are different variables to consider. Like, I live in Vegas, when I went on a road trip to Denver. My VR-4, felt like a damn Civic, could hardley get up some hills, Sorry rambling on here, The point is, try the lower fuel. If it does not ping or go crazy, then you can run it. If it does go crazy, switch back to the higher fuels asap.

 

lol. Since when does 93 octane cost more than 91 octane? Premium = premium here in Illinois and you'd be an idiot to drive your car on the bare minimum of what it can handle. Look at my previous post if you want to argue, because unlike this thread, I won't continue being repetative.

 

is your car a daily driver or only weekends

 

daily over summer, but she's parked now and will go under the knife (again) within a few months [time to fix my GT2530's and precision-build myself another VG30DETT]
