who puts wat into their car?? ive been putting in regular for a while but i think im switching to 89...prob shouldve been doing that for a while now..wats everyones input on that?

 

I use 89 everytime.

 

You need to use at least 91 octane. The manual for the car specifies that these cars need premium. There is a section in the FAQ's that explains why in more detail.

 

oem suggests 91. i dont have 91 here so i use 93. take care of your cars, put in what the manufacture suggests.

 

Actually the manual says 87 ... RECOMMENDED 91/93 for maximum performance.

 

neither .. I use 93

 

I use 91 since its the highest we get over here in ny

 

You can get away with using 87 but your performance will decrease. I stick to 93.

 

i use 87, performance is fine, and i get great gas mileage too! over 25mpg.

 

Yeah, I got banned for a week or two for advocating 87. Even the manual says you can use it as long as you do not get a knock. It goes on to say that region to region and gasoline brands might be different, so you can check around for some good 87, if you don't find it just put some octane booster in your car.

My knock sensor went out at about 200,000 miles and I used 87 for about 50,000 miles and the car now has 250,000 miles with no signs of damage. Recently I have been switching around with 87 and above but not lately.

 

I only use 91 octane. I put 87 in my previous 98 Maxima and it ran like crap. Horrible gas mileage (filled up twice a week) which I can only guess came as a result of the 87 (ruined knock sensor?), although I'm no mechanic so I can't say for sure. Putting the 91 in my new Maxima, I fill up every 10 days and I think the performance is better.

 

91+ for me, and about the octane booster and all of the fuel additives, i had a friend that put all that crap in his jetta and ended up stalling in the middle of the highway because his fuel filter or something clogged up. the mechanic says its because of additives, but it could be just because it was a jetta! but....91+ for me

 

so i guess i should change from 87 and go up...i hope to see a differnce..i really gotta start looking after my max better esp since im getting new clutch put in tomrrow

 

I've used 87 for the past 4 years. I've put more than 30,000 miles on it with that gas.

 

You will loose ponies if you do not go with the recommended grade, it is recommended for a reason. Just like the NGK plugs, they are recommended for a reason (people have had issues with other less expensive plugs, and in they ended up putting the recommended plugs in - go with copper if you want to save cash). There was a thread a while back where someone put their car on the dyno and they lost quite a few ponies from going down to 87 octane.

Why would you put something in your car that will hurt its performance ? What is the purpose of adding/spending money on mods if you will be putting this lower grade of gas in ?

 

87?? 89?? can you guys say change knock sensors soon? i drove my car on 89 for about couple of months. say bie bie mr KS. lower octane will cause engine pinging, and detonation.

 

Amen brother!! I put 87 in one time and won't do it again, might as well get a honda because it performed like one. The lowest I go is 89 and I only do that when short on cash, 95% of the time I'm running 93 and the max loves it.

 

why drop to 89 wen short on cash? i just throw a gallon or two in there wen im short. the top of my tank has grown mold and has bird's nests now. u know i hear them sometimes, its tru

 

I've been using 89 since i got the car about 2 years ago. Nothing going wrong at all. Power is there and mileage is great. Maybe i should try 91 sometime to see if i get better mileage.

 

Are the birds cuckoo?

 

my max performs just as good on 87 as it does when i use 91. i dont notice any difference, and i get great mpg either way. more expensive gas, is just, well, more expensive. i personally think its a mind over matter thing, ppl gotta buy the most expensive thing for there ride all the time becuz they think that more expensive is always better. it usually is, but i wouldnt say it is in this case.

 

Since when does knocking kill the KS? You can run any octane you want and it doesn't really matter for the KS. If it doesn't ping, who cares.

 

93 all the way!!!!!!!!!!!

 

93 all the time, 91 when I can find it, and 94 when Im in new jersey cheap gas bastards.

 

91 is all I will ever run.

 

its not for performance wise, our car is recommeneded to run on 93. its like walking outside with no shoes you dont have to but its recommended so you dont get blisters and shiet. lol bad analogy but you get the point

 

91 not 93.

 

I can't find 91, everywhere it's 87-89-93

 

near my house theres an american racing gas station with CAM2 110, 120, and 130 octane so on the weekends i put in 93 then like 5 gallons of CAM2 the car hauls

 

why bother wasting money on cam2 theres no point unless your boosted. put in 91 or 93. treat your car how u want to be treated. would u want ur car to feed u dog food or filet mignon?

 

By that analogy, I am planning on feeding my car filet mignon flavored dog food since the gas prices are going up 14 cents each gallon!!!!

 

i use 91, and damn jealous of you guys who have 93

 

reg unleaded from day 1 and runs fine.

 

I put 23, Runs great.

How many stupid thread like this????????

 

NEITHER!! 91 or higher is what it calls for...

 

I use Shell 93. My manual reads 91+ But, why would 87 oct. ruin the KS? If the KS job is to detect detonation, why would this hurt KS? Maybe the pistons/cylinders? NO?

 

i dont understand u guys...is the extra 3 bux to fill ur tank with 93 or 91 really gunna hurt u that much in the pocket? Just do it right treat ur car right, she will thank you in the long run when u have 250k on the clock

 

Some threads need not be started ... this being a perfect example ..

time to this thread as NmexMAX said

 

Nothing but 93 since I bought it. We don't have 91 around here. The $1-2 dollar savings on a 10 gallon purchase isn't enough to make me switch to a grade that's only "acceptable" for my car.

"For maximum performance use premium unleaded fuel" means exactly that. I don't think Nissan put that statement on the gas cap for the he-ll of it.
