370z requires premium fuel?

But it would still be safe if you were to use it right?

Maybe... My experience with higher octanes is that after a while, it screwed up my catalytic converters... It really won't help you if you're running a stock car. You can use it if you want, but I don't think it's good for the cats and it's certainly not good for your wallet.

Yes, it is safe. But not necessary on a naturally aspirated VQ unless you are tuned for it.

I have a 2006 G35 Coupe 6MT with a tune, and one of my maps is tuned for 100 octane. It does yield a few more hp and smoothens out my powerband, but its nothing like forced induction.

I only use my 100 octane performance map when I track the car. Mostly for additional safety since 100 octane would be less likely to knock.

^^^ What he said.

Here in England our 'normal' fuel is 95octane - Nissan recommend 'super unleaded', which is 97 or 98octane.

I run my 350z with 98octane (super unleaded) - and tests in at least one car magazine have shown that 98octane increases the horsepower slightly and/or it's more economical than 95octane. Also, the owners' manual for the 350z warns you that you should only use 95octane if you really have to - is this the same for the 370z?

Personally, I wouldn't use anything but super unleaded and I assume it's the same for the 370z.

In addition, I assume that the ECU will adjust itself to account for different fuel types, as I believe it does in the 350z.

Gasoline formulation varies a great deal between the U.S and the U.K. - it even varies here from season to season; region to region and perhaps even city to city.

Thanks for that - your reply prompted me to Wikipedia 'octane rating' - and it's very interesting...

Octane rating - Wikipedia, the free encyclopedia

When E85 becomes more popular in California (if our sh!thead of a governor gets his stupid squishy head out of his lazy republican @ss) I'll be tuning my Z for E85.

I've been reading that people who convert and tune for E85 are making quite a bit more power... And forced induction is safer because the compression for E85 is supposed to be higher for E85.

Any thoughts?

Thoughts? I think that The Cyberdyne Systems Corporation may be monitoring the interwebs and you better be careful about badmouthing the T800 series!

That's... well... strange. But hey, I guess I should be more specific, right?

Your governer played the role of the T800 Terminator series in a couple of movies and I was just warning you before he shows up in a time bubble.

Crash · 02-07-2009, 07:25 AM

He can show up in a bubble and would be welcomed with the following conditions:

He MUST fix the crap he broke

He MUST be wearing clothes when he shows up! LOL

tvfreakazoid · 02-08-2009, 05:17 AM

WOW you guys use a lot higher octane than compared to America. wish we had higher octane more available her in Cali. Well we do have them available, but not as many and there expensive as hell.
