i dont know how the hell i butchered that sentence, been a long day should be still instead of see

 

I hate the word whatever, when you start a sentence with that, I almost blank out and don't take in what you say

I'm just sharing my opinion, I've heard plenty of car knock and ping and their owners are oblivious to the issue, but I do know that certain maximas are prone to the issue, just don't make it sound like your car is a cummins diesel with a half million miles on it when it's not the diesel comment is not directed at you, just an example of how people make it sound, more or less directed at the 7th Gen owner

I know the knock sensors are their for a reason, but having been a tech, something as simple as fuel does make a difference in drivability over the long run, it's very hard to explain to to people that spending a couple extra buck does make a difference and will save you time and money down the road, I can't tell you how many x-girlfriends, past friends and relatives I tried to explain to that they need to run 93 because the car required it, did not matter that the car was a turbo, that it knocked like a wrench was hitting the engine, that it was an M3 that did 0-60 in 4 minutes, or was getting **** poor gas mileage, and these where all people who thought nothing when it came to spending 5 bucks for smokes, getting the car washed for 10 bucks every other day, and getting that 4 dollar coffee twice a day.

Thats what hits me when I hear I don't use 93 but I should.

With all that, when I was 20 I never understood why a BMW, Acura or Nissan with 100k suddenly died, but now at 30, I know

 

Just like how we think 93 helps us, is in our head... 87 helping you is in yours.

There's no need to argue it, and why in the hell are you even bringing in those cars to compare to?! It's well documented that 93 > 87 in every way except for cost.

I drove my 5th gen 250 miles a week, tried every grade of gas.

18-20 on 87
25ish on 89
always 25 or higher on 93

Those were my results after trying each grade on every tank. Not to mention the gutless feeling I always got w/ 87.

These are just my findings, no Maxima is the same, maybe some take well to 87 better than others, but this guy right here will always use 93 in a high compression motor.

 

that is what your suppose to use, compression ratio, the advancement in ECU being able to retard your timing, was to protect your engine if you got bad gas, or it was accidentally filled with the wrong octane, it suddenly has become the reason to use 87 in everything that should be running on 93

 

I think next time before you comment you should read the post again, ill give you a hint at the main point. there is a difference and 93 is greater than 87 it helps in many ways. I said nothing against this main point you are arguing here. AGAIN for the third time let me EMPHASIS my real point (ps im doint this gain cause I think its funny how many times people havent got it. im saying the members here who say "my car is way faster with 93 octane" are wrong. thats it. do you get it now?

thats great for you that you tested this out, tho I dont believe your numbers....at all and actually feel you are possibly fibbing or not making the test accurate or fair possibly in some way (ie more city driving on one type of fuel than the other) cause even in winter(in minnesota) when I try to get bad milage with of coarse 87 octane cause thats whats in my head.... I never got worse than 22mpg with a good mix of city/highway. just went on a trip and got 29 on oh what was that.....87 oh boy!!

sorry man but your points were funny so i had to be a jerk.

Touche.

The whatever thing was just that. It wasn't intended to be an argument of any sort. Just a, "Where do I go with this," comment.

Yeah, my Max tends to turn into a maraca when I run anything less than 91 now. Granted, I'm almost to 170k, so I'm sure that has something to do with it.

I like the idea of people who value Starbucks or their Camels over car life. I never thought of putting it into that perspective. Maybe I'll start using that argument with people who try to argue that their car is "just fine" with 87 in it when it should be running 91 and up.

Now that I've seen my gas mileage shoot through the roof with 93, I refuse to use anything less ever again.

 

Probably.

We never got a code or experienced a drop in timing and performance until she started using 89, then 87, then the cheapest 87 around. Going back to 93 didn't fix it, so I knew the sensor was dead.

Just coincidence, I bet... but I can't disassociate the two occurrences.

 

since new my 03 max never saw anything below 93, runs super smooth and soo powerful!! oil changed every 2500 miles and every 4 tanks lucas fuel system treatment

 

running lower octane should just force the computer to pull timing. I run 87 on old maxima with no issues, it already sounds like a tractor anyway.

 

let me clarify what octane ratings really mean b/c it seems some of you are confused?

the different ratings refer to the combustion temperature of the gas. so 87 is going to combust before 93 does. now why is this important? your car ecu is designed to time your engine's working to a fraction of a second. (i.e. when fuel is ignited)

what is knocking? this is when your engine PRE-combusts (early) which is really bad. think of your piston going up and down for power. but when it precombusts basically on its way up it forces the piston back down. like a hammer banging down on it. this is why we got knock sensors to detect this. once this happens your ECU will go to a "safe mode" mapping which will retard your car's timing making it less powerful and less efficient.

they recommend at least 91 octane for a reason. in the long run, going with what they recommend should save you time, money, and hassles...

 

 

No.

Octane refers to the resistance to auto-ignition.

 

for some reason the 1/4 mile doesn't care about 87 or 93 on a mildly modified maxima. i wonder why...

guess what your car is 100 times more likely to knock when it's hot out. getting it to knock when its winter is a much harder task.
