I added some Toluene to my car today (25% mix)

I got out to drive it and test it out, pulls harder ect... but it knocks upto 125!

I have the stock knock sensor, most of the time it reads 45-55.

It doesn't constanly knock higher than normal it just spikes like 1 or 2 times to 100-125 through the rev's.

The car runs alot smother and idles better. It's running better in every way!

But the knock is really high... Should I be worried? Should I delute it?

 

well you did delute it if you added 25% to your tank

 

no no no no.... i mean should i delute it more!, i am at 1/2 a tank right now.... should i fill up to make up for it?

or should i not be worried...

 

when does the knock occur? Under WOT or when you lift off and it coasts down?

Tim

 

WOT. under boost of cousre

 

quick question, sorry its a little off topic.

I was talking to somone and refering to WOT as wide open throttle. But does it actually indeed me Wihout Thottle???



Thanks in advance, stopped using the term because I was confused so badly!!!

MY car is for sale for 11,000 btw, GREAT car =o

 

Toluene doesn't burn in the same ratio with air as gasoline does. So by putting 25% toluene in your tank, I'd guess you were really about 10% leaner overall compared to gas.

When you run toluene, you need to use MORE of it to burn up with the air.

 

Thanks wargasm!

that makes sense, but the thing is that im all ready running really rich (enough to cmopansate for the Toluene

but ill still richen it up a bit

 

You also want to be careful with your oiling in your engine... I've heard that running over 20% Toluene is bad because it washes oil off the inside of your engine. I'd add some premix if I were you. I dunno how true it is, but better safe than sorry right?

 

Damn, I wish my dad was here, I could ask him about this, being a chemist and car guy he would be real useful. I know he has mentioned burning the 55gal drum in the factory full of toluene in his Supra and my FD, but, thats as far as its gotten so far. If I talk to him soon I'll ask what he has to say about it. Good luck anyways, Josh

 

time to put some oil in the gas tank, thanks guys!

 

I would not run over a 10% mixture without retuning for toulene. I'm not a chemist so this is going to sound pretty rough, but here we go . In laymen's terms, toulene's perfect stoichmetric mix is something like 11 to 1. (gas is 14.5 to 1 I believe) so, even if you are running pig rich at 10.5 to 1 for gas, your pretty lean in terms of toulene.

I run one gallon of X or T in every tank full that I put in my Car. I also add 4oz of MMO to compensate for any lubrication inbalance. I have not had a problem in over 4 Thousand miles.
