What type of octane do you guys use for350z??
i know that 91octane is the recommended fuel but is it ok to put 89octane?
i've heard that if you put 87octane then it would make a knocking sound in the engine.
So would 89octane be alright??or no?

 

91 octane ONLY...

If you put 87 you're only saving a couple dollars per tankfull and you're cutting your engine's life short by a lot.

Only cheap-asses put 87 in a performance sports car...

 

Oh god not again, search



use E85

 

what about 89octane?

 

What does the owner's manual say?

89 octane is in the same boat as 87.

 

premium only cheap A$$....END THREAD....

 

I believe the manual states the lowest grade you should use is 91. If you are in a remote town and they only have 87 or 89 then it is okay once. Over time it is bad.

Just use 91 and don't worry about it.

 

Just saw the other thread you made...

Buy something else for your first car.

 

PURE ALCOHOL!!!! Fck gas pumps I buy my $hit in drums

 

just put diesel fuel in it. you will get great mileage.

 

its ridiculous prices. My Z runs on my own sense of self-satisfaction.

 

 

I don't understand the thousands of threads asking about octanes when the manual states at least 91. Just follow it or buy another car. Sheesh!!!!! If you can't afford a few more dollars at each fill-up, you are living way beyond your means with the Z.
