SO you use 91 and ONE of your injectors died. So what? Do you think they supposed to last forever? The point is that cheap gas will help you to replace them ( and other parts ) more often. Get it? And as I said its not just the octane level - it's other quality considerations as well. You don't seem to comprehend my points very well!
How would you suggest I supply concrete proof? Why don't you go ask a chemical engineer if what I say is true? You'll see. Don't expect some auto mechanic to tell you what is the best gas to use for your car. To tell you the truth - they don't really know - but most importantly - and here is the key - they don't care what gas you use. They do care that you think they know though.

like I said you have no proof, so why should anyone believe you??? you say go ask a chemical engineer, yet you are the one whos making the argument, so I'm asking YOU for proof!!! but I didn't expect you to have any so I don't see why I'm even pursuing this....

EdgeProductions

if you read our owners' manual it states to only use 91+ octane in our car if I remember correctly for the 92-94 SE VE30DE equipped cars, however if you cannot afford the 92-93 octane gas at least do 89 because I ran 87 octane once with no choice as they wer out of 89, and 92 for some odd reason when i was there and my car ran like total junk!

Hope I am not repeating a ton of people by saying this, I just failed to read through everyone's posts first! SOrry!

I already asked you - but you didn't reply - How do you expect me to supply proof? You didn't answer of course.
I told you how to verify the info with academic authority.
I don't give a crap what you believe. Those who are intelligent enough, will at least accept the possibility that I am correct and make an independent effort to verify.Others will continue to wallow in hearsay and their own reluctance to learn that complex issues don't have simple answers.

Sir,
People don't make arguements without facts to support what they say. If you're willing to say this grade gas is better than another grade of gas then you should have some sort of reason and evidence supporting your reasons. Otherwise, you're basically blowing smoke out of your ****. The people here really don't like **** smoke, they like facts.


Sir,
Please don't tell us to verify if what you say is true. You should have done that before you said anything. You are responsible for your words, not us.


Good day sir.

objection your honor. jk

Objection denied! Now sit down or I'll hold you in contempt!!

Well, everyone else is kicking in, so here's my gas knowledge:

I have a 91 SE (auto). When I first bought it, it had 50,000 on it. No idea what octane was run for those.

I started out all gung-ho with 93 octane (or 92 depending on station), and continued this way for the first year or so. Car always ran great... no problems.

Then I lapsed into 87 octane because I was trying to save money, driving in the city all the time, lots of idling... much cheaper per tank.

I never really noticed the difference in power until I filled up with 93 again one day. Then I'm like... whoa!!! this car moves!!! I always used 93 for trips because I knew I got better gas mileage, and didn't mind the added expense for a tank or three.

87 is cheaper. I've had no problems because of it. 92/93 do make my SE run better, and do increase my fuel mileage. I currently have 150,000 on the car, and have only replaced the rotors once, the power steering pump, and 2 y-pipes.

The argument here may just be personal preference. I've used both high and low octane, and see the advantages to both.

Have a good day yourself there old buddy old pal old friend.

Nismo87SE

It seems as everyone's car is different. My 87 max would ping on 87 octane with more than 1 passenger with the AC on. I seen the best results with 91+ octane (I had advanced timing and other free mods). My uncle runs 87 octane in his 91se and it has over 200k miles, plus runs pretty well. One thing is for sure with extra weigh you'll lose effiecency with 87 octane vs 89+. I checked my uncle's timing and it was running at 12*BTDC, stock is 15*BTDC. I didn't bump it because he claims its easier to run regular than mid or super LOL. If anyone runs regular unleaded check your base ignition timing and see if its been retarded over stock setting.
What does this mean, 87 "should" be ok if there isn't any pinging or detonation under load. But then again it would take a 30 cent difference from 87 octane to offset a 1mpg gain with 89+ octane.

Jiggaman

Yeah, my 90 GXE manual says to use 89. But if your manual says to use something different, go for it. They're so over cautious about that kinda stuff they wouldn't possibly recommend it if it would hurt. I mean jeez, like nismo1989 said:

Higher octane has better knock-reduction properties, but once you get to a high enough octane rating, the anti-knock principles are going to start making little to no difference at all. Just go with whatever feels the best to you while you're driving. If two feel the same, go for the cheaper octane rating.

burma

I used 87 in my 1987 SE and never had any problem. I sold it at 237,000km. I used 87 in my 1995 GXE and sold that one at 239,000km. Never an engine problem with that one either. I'm using 87 in my 2002 GLE and i'm sure it will be the same. If there is no pinging, there is no problem.

White93SE

I may be a newbie, but I sure as hell know more than 90% of the ricers who need a skyline body kit. The length a person has been here or the number of posts they make doesn't correlate with what they know. Not long ago were you asking about the illumination wire on your head unit...

performance and mileage.. @ 260+ on a whole tank of 87 octane. best feeling and mileage was 93 octane sunoco getting 330+ with a/c

nismo1989

Then maybe you should leave here and go try and show up those ricers with the skyline kits... stop tryin to be a bada$$ and act like you know everything and can discredit other people's opinions/experiences.

I have an idea - use whatever gas you like to use. There is plenty of information out there to determine your own opinion. If you like regular, then use it! If you like premium for whatever reason, use it! If you like pure f'n alcohol for whatever reason, use it!

Bottom Line - Who cares what someone else uses in their car, worry about what you use in your own car.

BoyGenius84

My technician is one of the top ten Nissan Techs in the country (He is top in the North Central Region). He said that while it's better to use the higher octane, 87 won't hurt it.

BoyGenius84

It's not so much the octane that causes that, as it is the quality of the gas. I was told by my tech (again one of the top ten in the country) not to use BP gas. That's just my two cents.

BoyGenius84

Whoa there, Buddy. If a man has been repairing cars since he was 12, i think he will notice when cars using certain kinds of gas fail before others. If your mechanic is experienced, he will know what kinda gas to use. As far as chemical engineers go, they can tell you what is in the gas and what is not. They cannot, however, tell you how it will affect your engine.

When I had my VG, I would use 89 normally. Sometimes, I would switch to 93. Normally, I use Mobil or Shell.

OK - here is my suggestion to all you 85/87 octane lovers.
Everybody who has a Maxima ( any year any engine ) should use the cheapest lowest octane gas they can get their hands on. You know the type of stations - the ones that sell the gas that has been made at refineries with real low cost operating budgets. Ya - refineries that don't really get ALL the impurities refined out of the gas. Ya - the type that don't put any cleaners or conditioners in the gas. Ya - the type where all the equipment is so old and rusted and the staff so underqualified that sometimes the gas even has some water in it.
Ya - the cheapest gas around. Thats what you should use in your beloved Maxima.
This way Nissan will make more money on selling fuel system and engine parts and they might be able to lower their prices on new models.
That's good - cause I gonna buy a 2003 model soon.

I suppose your the same people that think that a $49 sound system is
all you really need. Sure - You been listening to it since you was 12 years old. Still works and never had a problem with it. Why should you spend more?
Why do you think there is 90+ octane gas available all over the place.
OH, I guess it's just for the ferraris and other high compression engines out there. Ya there's millions of em all over. Right.
And also for the suckers who just wanna pay more for their gas when there is no real benefit for paying more. Ya right - there are at least 100 million of those in North america alone. Right.

Use whatever gas ya want - I don't give a crap.
And don't forget that when there is a starting/performance/hesitation/heat/smoking/carbon buidup/varnish buildup problem.Check here for a perfect example...... http://forums.maxima.org/showthread....hreadid=125936 It's not the crappy gas you've been using. It's something else. It's never the gas you've been using because then you would look like a tightwad fool. That won't be allowed to happen - RIGHT?

did you find any proof yet...I was guessing you gave up since youy never had any to begin with?? just wondering.

sharky

I will not supply proof to you for this simple reason........

I don't give a crap what an ignoramus like you ultimatly believes.

Is that clear enough?

Scott Fife

I agree. I have a stock 89 VG with 195,000 miles. I've never used anything other than 87 octane... no engine problems.

nismo1989

He is no ignoramous, I assure you. I believe what you say about higher octane gas being better for your car becuase I live by that philosophy, but DA-MAX's opinion does not make him an ignoramous. He is a smart guy who has contributed a lot to the better of this forum and if you do a search for informative usefull threads he is involved with 90% of them in some constructive way.

sharky

Well - one would think that if he is so knowledgable that he would know about the benefits of using quality fuels. I guess he can't know everything.
Does he recommend using the cheapest engine oil too?
What about tires? Does he recommend using the cheapest
tires too? Why not? They work just fine. Never had a problem with them. More expensive tires are just a waste of money. Ya - right!

nismo1989

All of those things do depend on your driving habits. You have to weigh the economy vs. the practicallity. My tires are $1200 to replace, and that is rediculous for the car I drive. I can safely get the same performance out of my car with a set of $600 tires, half of the cost. I drive hard so I use 93+ octane. When I use the nitrous I fill my tank 1/4+ with 116 octane and the rest with 93. When I take road trips I fill it with 95 octane. When I'm in the city I use 93, and at the least 89 with my timing retarded to stock (15 degrees). I use Pennsoil synthetic because after 5K mi.+ it still is golden brown on the dipstick. I use K&N oil filters becuase I took apart a fram and it was filled with shredded paper. Some people say I'm dumb (my dad included) for spending the extra money and that is fine. I say that preventitive maintenance doesn't cost, it pays. It works well for me because I drive my 12 year old car like I bought it new yesterday.

nismo1989

... as far as what DA-MAX said, I respect his opinion regardless of whether or not I agree with it becuase he has contributed so much of value.

I never said using higher octane fuel is a waste it has its ususes for certain cars and certain situations! but you have to realize in everyday driving situations 87 octane is the manufacturers suggested octane. I ask for proof because you are refuting the manufacturers suggested octane rating...thus you are saying the manufacturer is wrong....and you feel that you don't need proof to refute the damn manufacturer....whos the ignoramus??? like I said find me proof...until then I'd perfer to stick with Nissan's suggested rating rather then some nobody with a big mouth who claims this and that yet can't back **** up.....I'm done....

matt1sd

man, how long is this gonna go on for? both sides have their proof (or lack there of) of what type of gas to use. we could go on for years beating this subject into the ground, which we almost have. (this thread is going on almost 6 pages ) but anyways, i think its up to the owner to decide on which gas to use. frankly, the only difference that i can tell between 87 and 91 (91 is the highest here in san diego) is that i get a little better acceleration out of the 91, but otherwise i cant tell the difference. i get the same mpg on both. my dad gets on my case to use 91, most of the time i use 89, which is a compromise between high octane and price. and its also hard to go with the higher octane out here because the avg price is like $1.75/gal for 91. so im not taking sides. thats just my $.02.

I think you meant to say 'cuz' instead of 'cause', but I could be wrong.
