well i have a b18c1 and my motor is making some sort of sound kinda like marbles hitting one another. I made a post not to long ago but i just wanted to know if anyone else knows anything about running 89 octane with octane booster in my motor? will it still detonate? whats the effects of running a lower octane than recommended?

 

I'm sure if you run 89 octane and add octane boost you should be around 91 octane anyways, I don't see y not just get 91 to begin with. But if you are hearing a pinging noise and it's continuous you should be lucky nothing has broken internally yet.

 

I would just use 91 to begin with and not deal with having to go and get octane booster everytime. Besides, octane boosters aren't really all that they are made to be. I think you would be lucky if they even give you a point or two.

 

well no i filled it up awhile ago cause i dont really drive this car, it has 3/4 tank left i tried Siphoning the gas but i cant even get the gas out. It seems impossible to get the gas out of the tank. I put the tube all the way in and theres not a drop of gas was on the tube. do you guys no any tricks to getting the tube to at least touch the gas or is there any other way of draining the gas?

 

get the 91 octane.
WTF is the point of 89 octane/ and booster?
I know you got 91 octane out there cause i saw it.
I bet it's even cheaper to get 91 than get 89 and add booster.
What's your problem?
There should be a plug drain plug on the tank.
I'm willing to bet it's near the bottom.
See what that does for you.

yea i wasnt trying to do anything i just accidently put 89 instead of 91 octane and my motor started making sounds and i thought about it and i did put 89 on my last fill. What happenes to the motor? do you think its really messed up? im going to drain it tomorrow but i dont know where to put 7-8 gallons of gas

If you had said it was an accident i wouldn't have jumped on you like that.
Try a funnel and get some emergency gas tanks. those little red ones.
Find a car that like 89 and you're done. How long did you drive w?89 octane?

ive been driven the car for about 3/4 tank with a mix of 91 and 89 then i filled it up with 89 again so when it was all 89 ive only driven for like 1/4 tank. Man i think im screwed cause ive been hearing sounds i thought it was like nothing but it started always happening when idling nothing when im on the throttle. Ill try doing the funnel thing plus the small emergency tanks

 

Drain the 89. Get some 91 and see what happens.
You should be fine.
Come back if you still have issues.

89 octane is actually ok. make sure it is not something else with the motor.

well it still making sounds, i dont know what it is still sounds like marbles when its in neutral or the car is just on. Doesnt make any sort of sound when driving though or maybe i just cant hear it.

i tried listening to where its coming from but i cant make out were its coming from

 

so u drained the 89 and put in 91 already? If not I would just add octane booster for the remaining gas and just use it. Just try and drive on cold days (yea right, lol) try drive in mornin n evenings.

I'm wondering if the noise you are talking about is just a simple problem like valved adjustment and not detonation? See if you can get somebody here from the same town that would be interested in looking at it and helping you out.

i drained my 89 gas about 3 days ago and filled it up with 91 octane, also i had a valve adjustment a 2 weeks ago. I don't really trust anyone around here to help me check out my car so im not sure were to take it.

 

89 octane with off the shelf octane boosters would equal out to a 89.2 - 89.5 octane gas. No wonder your b18c was pinging.

does anyone care to explain what exactly pinging is?, and the effects of pinging?

oops i meant from were i live, sorry about that i didn't mean h-t

 

so the noise went away with 91 octane or does the problem still exist?

 

i think its fine doesn't make a sound, thanks everybody who helped me diagnose the problem. h-t = great technical resource

The story has a happy ending. lol

 

really, it depends on what ECu your running for damage. If your running the p72, you'll probally be fine since that ECU looks for a knock sensor. If your running a chipped p28, then it doesn't. When the knock sensor detects "pinging" (detonation/pre ignition, ect) it retards the timing.

You could have probally got away with finding a place that sells non leaded racegas, and mixed that with your gas.
