Thats great!!!

 

^ I'm going to post that for about every single newb thread I see. See if anyone ever gets the point. Hahah...

Doubtful.

 

89 octane. dealer says its ok.

 

 

There is no such thing as free horsepower. You payed for a 287 hp or 300 hp car so you have to use premium like Nissan says in the owners manual.

 

Do you actually trust a dealer on this. They sell cars they don't design them, I've yet to meet ANY dealer that new anything about the 350Z.

 

Won't hurt the car, but your ECU is pulling alot of timing. Should've just bought a car with less HP is you don't want to pay for premium.

I run 91 because that's all we get out west. The ECU is tuned for 93, so when I go to the track or dyno, I run a 1:2 ratio of 100 and 91 to give me a total of 93-94 octane. Anything less tha 93 and the ECU pulls timing. The Evo has the same problem, only much worse.

 

lord give me the strength...for the last time, its 87 octane!

 

Nowadays I put premium in it...when I first got it I was using regular for a while...I haven't noticed any differences for better or worse since switching to premium.

 

I just got finished using a tank of reg 87 octane on my G35 and noticed a zero change in performance compared to using 93 octane from the same gas station.

 

I use 50

 

yea u may not feel much of a diff but higher octane burns better, so i only use 93

 

i use 93 octane here in austin texas

 

Diesel

 

No pity from us Californians who have 91 only (for the most part) and probably pay at least 50 cents more per gallon for it.

 

93. No such thing as 91 here except at select Sunoco (I think) stations. 87,89,93, thats the picks.

 

I use water.

 

In some places Houston has 94 Octane

 

94, only 94
