Put super in your car. But if you have to put 89 grade in there, absolutely nothing will happen.

 

Couldn't have said it better. People always complain about premium being "so much more expensive." If you cannot afford a few bucks extra to put the correct gasoline in your car then you should not be driving that car.

 

Amen.

 

are you sure that's a 12?? it looks like 08-10 to me....

 

If you zoom in closely you can see the sensors on the bumper. Those weren't on the 08-10

 

Noticeable improvement in fuel economy using 91 or 93 compared with 87. It easily pays for the 2 or 3 dollar increase using the premium fuel. Don't cheap on gas. It's not worth it!

 

Thank you all, you've been a great deal of help. Premium it is!

 

Since were on this topic, I have a fuel question for you guys myself. I always run 91 in my G since its all you can get at the pumps in socal. Are there any benefits to running some Octane booster in the car to try and make the 91 like 93 or a littler higher octane? I figured since its summer here in socal the G might like a little higher octane fuel to run better. Thanks for your help?

 

First of all, congrats Mikeeeeey!! All I use is Premium 93 at the pump. I am very particular on which brand or company as well. I stick to Shell or BP. I wouldn't take a chance with cheaper or a lower grade gas. As some of the other members have already mentioned, it's definitely better for engine performance and efficiency, if you stick with Premium 93.

 

I use top tier gas when I can, around here we can get 93 octane. I would also follow the break-in period specified by the owners manual.

While there are a lot of differing opinions on how to break in a car on the internet, I don't think Infiniti wanted to waste ink by declaring on page 5-43

During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reliability
and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.

Instead of: "Drive it like you stole it"

 

What do you mean by built? Hand built like a GTR engine or built like all other Nissan engines? If you meant the latter, you would be correct.

I don't think that there are any benefits that you would notice. If it got better gas mileage, it would probably be offset by the cost of the additive. If you try it out, let us know how it works.

 

Wow, you believe everything you read? They are all in on it with the gas companies. Just like some cars have mobile 1 on the oil cap when any synthetic will do.


Anyway this is the age old debate that will rage on, put whatever you feel is right but I have been on regular for 3 years and my car runs great. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

 

I've read that Citgo has crappy gas :/[/quote]

Besides the fact that if buying from them it is support for a communist tyrant, Chavez......

 

mikeeeeey:

1. Lower octane fuel will cause the engine to run a lot hotter. These high performance engines need high octane fuel, period. For a while I used regular on an A6, I burned 2 coil packs that are bolted to the block (they were burned by high temperature) and the spark plugs were completely red when they were pulled. The mechanic's one and only comment was that this car was seeing regular fuel instead of the required higher octane one.

2. The difference in price from regular to super is probably about 20 cents. That in 14 gallons is $2.80. It's not really worth it, is it........

Would NEVER buy from Citco!
