Type of fuel required, plus knock 88 t ?

[garyb]

I can't find an owner's manual. I do have a light knocking that starts at about 3k rpms when I rev it in park. I hope it isn't rod knock..... What grade of fuel is recommended?

 

[Superjustin13]

91 or 92, and the fuel only causes Detonation. not a rod knock, thats a different subject. type of oil u use, Oil Changes, etc

 

[Yellow 13]

If you run the low grade stuff for a long time I know its not good for your car. I only found out about the minimum of 91 octane last year unforunately.

Here is how to stop your knock.

Buy a gallon of Toulene at a paint store. (Figure on spending 6.00 or more for it.)

Get a funnel that will allow you pour the Toulene into your gas tank without spilling it all over your paint. This stuff will take the paint off your car, so be careful.

Now, with a gallon or more of Toulene in the tank, your "knock" should go away. (And your cleaning your fuel system while you drive.)

Toulene is a pure hydrocarbon, and it's safe to run up to 30% of it mixed with pump gas on most cars. If your going to run Toulene all the time, you might want to add some ATF to the mix as a lubricant, but I've had no problems using it mixed straight with pump gas anywhere from 10 to 30%. (You can run higher boost pressure with no problems on this fuel....)

Hmmm...different thread, same subject :icon_idea

Would the Toulene cause an increased buildup of carbon on the pistons since its carbon rich? Im really tempted on doing this.

From what I've read, it should burn very clean...Xylene is an option as well. Has a slightly higher (R+M)2 content.

One more question, It sounds pretty corrosive if it can eat off paint. Do you think it would eat through any of the gaskets or rubber lines If I ran it in my car for a week or two.

It really isn't an issue of how 'corrosive' toluene and xylene are. In general terms, corrosivity suggests extreme high or low pH's, but since these compounds are pure hydrocarbons - i.e. nothing but carbon and hydrogen, they will not easily loose H+ or OH- ions (those that do are considered 'corrosive'. In fact, OH- wouldn't even exist in a true hydrocarbon because they contain only hydrogen and carbon. No oxygen).

What they are are excellent solvents for mostly hydrocarbon (oil) based solids like clear coat and paint. In fact, I used to use toluene to dissolve and strip pure wax from my skis.

While not corrosive, toluene can be very harmful to latex and other synthetic rubbers. If you dip a latex glove in toluene, it will cause the glove to majorly swell, and it will fall apart pretty easily. These types of chemical reactions are usually dependent on concentration and temperature.

In this case, none of that really matters. Gasoline (octane) is as oil-like, and as much of a hydrocarbon, as xylene or toluene, and would eat up a styrofoam cup (and maybe a latex glove) just as fast. If high octane gas isn't eating up your gaskets or rubber lines, then xylene or toluene won't either - especially over a couple of tanks at 30% or less. I say go for it.

Thanks for the detailed info Louky

 

[xarewhyayen]

knock and ping are very different. i think the "knock" this guy is talking about is unrelated to his gasoline question. gasoline with low octane could give a "ping" but dont mistake a knock for a ping. Some pinging is normal, thats what your knock sensor is for... to adjust when its pinging.

 

[Yellow 13]

Then why dont they call it a ping sensor smart guy?


JK.

$6.00 or more!? Hah! Try $17.99...or a twenty dollar bill:aigo: (after the governors cut):icon_mad: for one gallon! And it is hard to find these days, at least around here. It's because the tweakers:thumbsdow use it to cook meth. I bought some at McClendons hardware in Sumner, and it does work!:naughty:

Can anyone confirm the current price of toulene?

 

[jdub]

Just bought a 5 gal can of Xylene from Sherwin Williams for $50

 

[atlpd3147]

O ok. Anyone buy toulene lately? What's it going for nowadays?

 

[7m2ner]

So how much Toulene do you guys suggest to add when filling the tank up? just the one gallon? or should more be added? thanks

I have a question if i was to do this at a race where they check fuel with a tester would it show up on the tester?

 

[whenmunkysfly]

also does this actually add hp or does it just allow you to do things with it that increase hp like race gas

 

[jdub]

Xylene & Toluene are two solvents (among others) gasoline blenders use to increase octane...it should not show in a tester and does not contain lead.

I use 1 gallon of Xylene (it has higher octane per gallon) per tank...that will increase octane from 91 to about 93. It has the same effect as race gas...it decreases the likelihood of detonation. Be very careful with both Xylene and Toluene...nasty stuff...you don't want to get it on you or your paint

Here's the math to figure octane using either:

(A x gas octane) + (B x 114 or 117) / (A + B) = Octane Value

A = gallons of gas
B = gallons of Toluene or Xylene
114 = octane value of Toluene
117 = octane value of Xylene
