fuel 03-05 Z car and G35 coupe

yes, read your owners manual

Yep, you're better off just to keep using your skateboard to get around.

You think anything that can deliver the same performance will run on lower grade petrol? Well it may if it's a big lazy V8 but it will be at the expense of far higher fuel consumption and more expensive overall. Have to hope they give you big rebate to allow for the excessive fuel burn.

I don't have an owner's manual. I don't have a Nissan product. And now I don't want one.

Thanks. It looks like I will have to go to or call several dealers to find out for sure on the Z and G. I suspect that the knock sensors will back off the advance to let them run on regular, at a cost of a few hp. I'll see if I can find the compression ratio.
