Just bought a 370Z-does it have to run on premium fuel. Don't know what it has been run on previously

Look at the gas gage. Look at the gas filler door. The info your looking for should be there.

Thanks, I am aware of the fuel it calls for (premium) but that is not always "necessary" so I was wondering if anyone has deviated from the recommendation.

Penny wise. Pound foolish. Ben Franklin. With such a nice car why take a chance? My Mercedes owners manual has all kinds of "What To Do's" is 91 octane isnt available. My advice is put the good stuff in it.

I have not deviated. I stick with the premium..

Stick to premium fuel, otherwise it doesn't run well. It gets better gas mileage which makes up for it costing more than regular gas.

I’ve been running regular gas without problem

I have never used hi test in any car i have owned ..................if it does'nt ping you dont need hi octane fuel!

Andy probably does not realize he has been losing power and fuel economy by running regular in a car designed for premium.

You’re going to run that engine way hotter in exchange for cheaper fuel... especially the summer days. You’ll slowly destroy your motor. Don’t be cheap! Use what’s recommend. Especially if you’re running a particular turbo car

hell mate I discovered a little known secret, not only do I get better fuel mileage but nobody knows what the secret is that keeps getting me much quicker times in the quarter mile, I run off road diesel, Now dont lettem catch you but this little trick getx me the checkered flag everytime! I leavem all in a cloud of smoke!
