2 things, redline and gas....
 

okay this has been discussed before but i can't seem to find the thread. so, what gas does this damn thing want? i've given it 93 and 89....and i just put 87 for the first time cause i'm going poor. and it's the same thing isn't it?


also, i still will never understand how my 92 dx 1.5L sohc, redlines at 7,200 rpm...what rpm does it really give out on givning power though? this is driving me nuts

RE: 2 things, redline and gas....
 

Use whatever gas your owner's manual recommends, which I suspect is 87 octane. Anything else is just a waste of money and will not make your car run better.

i don't have an owners manual :(lol don't need it! alright i'm also assuming it's 87 too. but what's up witht he redline dude?

RE: 2 things, redline and gas....
 

As mentioned by DelawareDon, if your car runs fine on 87 octane gas, then keep using it.

The ECU cuts off current to the fuel injectors at about 7,400 rpm to protect your D16Z6 engine from being damaged. This function is called "Fuel Cut-OFF Control" (see picture).

dude, i love you. so i have power up until 6,650?

RE: 2 things, redline and gas....
 

Yes (for the D15B8).

RE: 2 things, redline and gas....
 

i figured, but quick question. why does the limiter go to 7,200 for? were they smoking or something?

RE: 2 things, redline and gas....
 

But doesn't premium gas helps your motor to be clean and helps fights build up deposits in the engine.
i understand cheap gas is bad for your engine.

RE: 2 things, redline and gas....
 

The limiter is intended to protect against blowing the engine. It doesn't correspond to the rpm for best performance.

Also high octane gas isn't inherently any "cleaner" than regular. It may have more additives in it if it is a name brand but that's a tiny difference. If you engine doesn't knock when you use regular, use regular.

RE: 2 things, redline and gas....
 

Good question. I don't have an answer.

(Pardon the threadjack: Welcome back mk378!)

lol damn, now i know it's an enigma

RE: 2 things, redline and gas....
 

well my thing is WHY push it that hard???? just because the computer will ALLOW it to be reved that hard doent mean you have to......


case and point..... my 94 civic i bought with a blown Z6 stock computer..... and he said hes replaced it several times.... so im preaty sure he ran it to the rev limiter WAY TO MUCH and over so many times well... eventualy its gonna do SNAP and cause HUGE FAILURE.... main reason why i got my 94coupe so cheap ;)



and now that i have it all swaped out and another Z6 instaled i tend to be easy with it... i TYPICALY shift around 2.5K rpms or maybe 4K rpms every now and then. and ONLY WHEN I WANT TO HAVE ALITTLE FUN will i kick that sucker up around 6K rpms...... to me its just not needed to rev that high.... higher ya rev the more damage you can do.


just be easy.... save that motor alittle it will thank you and live longer ;)

RE: 2 things, redline and gas....
 

lol never said i did, just wanted to know why it says that and where does it give out at.

you just made it seem like were driving twins bro =)

KOFMIBUELG -Generally speaking, the same detergents are in 87 octane as are in 89, 91 and 93 octane. Having said that, you need to be aware that gasoline companies, as a whole, have gradually been decreasing the amount of detergents and other additives in recent years. The bottom line is that if you want to keep your injectors running clean, no matter what brand of gasoline you buy, dump a can of injector cleaner in your gas tank every time you do an oil change. Once again, there is NO benefit to running a higher octane than your owner's manual recommends. If you do, your just wasting money and putting additional dollars in the pockets of oil company executives.
