Whats the recommended octane for a JDM D16Z6? Please specify whether its RON or the US rating.

 

Is there a such this a JDM d16z6?

Anyways I run the lowest octane (?87?) arco has to offer. As long as your motors stock you should have little to worry about. If you have i/h/e maby bump it up to the middle grade octane if you spark plugs start to get white.

 

IHE doesn't change your compression or ignition timing, so why would you run higher octane for that? If those mods cause you to run lean you will want to raise your fuel pressure. Thanks for responding though.

Anyone else? I was hoping to find the actual factory recommended octane. Rather than put in some 87, buy some bottles of octane booster just in case, and cross my fingers.

 

Um.. The reccomended octane is unleaded.

87,89 or 93 will work...

If you have your timing advanced then you need higher octane.

Search.

 

I did search, thank you.
