My car didn't come with an owners manual, I'll have to order one. Do you guys put regular, middle, or premium in your G's? What does Infiniti tell you to put in?


thanks

 

I tried using the search, but nothing came up under "gas." go figure

 

91+ octane only

 

Yup...91+.
Despite what other ppl have argued in many threads on the same subject.

Go to Infiniti's site and there you can down load owner manuals.

I remember a statement in there saying you can use 87, BUT only fill 1/2 tank,
don't accelerate hard, don't drive at high speeds while only on 87 and fill the rest with 91+ as soon as you can.

 

premium

 

which car do you have? the previous generation AT sedans only require regular (download the manual from inifinti website to find out for sure)

 

I use half 91 half 101

 

Guys you can only download the manuals for the current couple of years, now I think it is 06 and 07. If his car is before then, that doesn't help much.

The following apply if you have a sedan (I don't have a coupe manual to reference so I'm not going to say it is a blanket equal though it *should* be)

If you have an 03-06 automatic you have the option of putting in regular though it says you will get better performance from premium.

If you have an 03-06 manual then I am 99% sure the manual says that premium is required.

I assume you do not have an 07 without a manual so hopefully the above will help you.

 

Where the heck do they sell 101 octance? Holy moly...IMO that's a waste of money unless you're an indy car.

91 octane or premium is the recommended gas from Infiniti.

 

Ive used regular, midgrade, and premium and have found absolutely zero difference between any of the 3.

No change in mileage, power, or knocking.

People will give you different opinions. My advice is to try it for yourself and see what happens. Just put in 1-2 gals if you are not comfortable with lower grade.

 

^^^this only works if he has the engines that are ok with that. Without knowing his engine, you are playing with fire to just suggest someone try something.

 

We recommend premium 91+ on all newer Infiniti vehicles.

 

I always put 91 or my higher in the cars I drive, unless it's a truck or some POS.

 

thanks for the replies, I just realized there is a thread in the G-Spot about the same topic.

 

I use 91, thats what they tell you to use. It prevents detnation or something like that. Because of the higher octane


You can get race fuels (being 101 etc etc) from Sunoco at the tracks, atleast down here in Florida, I'm not sure if they have Sunoco in other states.
