$0 cure for detonation
My 2000 Ford Explorer with the 5.0 decided to start detonating on 87 octane. I went to 89, which worked for a while, but eventually it began detonating again.
So I started it up, held the engine to 3k rpm, and dunked a vac hose into a bucket of water.
Result: No more detonation on 87 octane.

I'm actually down to 1 miata, which is waiting on the Link board to be repaired or replaced by FM.
Cars are like golf clubs, you gotta have one for each specific job.
Wifey "claimed" the explorer a couple of years ago. She had a neon at the time, and I had a work truck, so that was OK with me.

HAHA no, not a joke, no engine damage. :gay:
Detonation can occur from carbon build up in the combustion chamber. I believe that this is because the carbon takes up volume which results in more pressure. The water "shocks" the carbon, causing it to break up. It ends up getting sucked through the exhaust valves and pushed out the tailpipe.
You can also try pouring a bottle of ATF in your fuel tank. ATF is a pretty good detergent. The water would be more effective.

naw man, you put a vac tube in a bucket, and the motor will suck in the entire contents of the bucket with a quickness. Probably something like 1 gallon per minute. I used about 3 gallons of water.
No detonation still.

But be carefull with this!! Water exploding in a combustion chamber can cause engine deffects...
But it really cleans up good... (nice 2 see after a bad headgasket, all carbon deposites are gone...)

I gave my M-I-L an 8oz bottle and some vacuum hose and showed her how to gradually feed the water in over a 2-3 minute period. Not sure what the "shove a fire hose in the intake" method does or doesn't do compared to that. I know that doing two of the 8oz bottles a couple of times has really helped her car. She had the typical 1999 shitty coil pack problem and managed to coat everything with a nice carbon crust. Tons of problems associated with that crappy coil pack. Mazda should have warrantied that stuff because we have spent hundreds repairing the damage from it.
