When does it begin to hurt rather than help I went to the track last weekend and all They had was 110 so I put in a little but didn't know the breakdown.
P.S. Im at 5000-6000 feet above sea level.
Thanks

 

Im pretty sure that 103 is going to be the highest unleaded you can get.Anything higher is leaded and if continued to use u will burn out your oxygen sensors.

 

run what you are tuned for.. simple as that.

If you run too high an octane than you are tuned, expect lower times.

 

i pump 106 into my truck

 

editted... wrong info... see below.

 

I have no idea how you came to those octane figures

Toluene is:
R+M/2 114

So that mix is 279 + 114 / 4 = 98.25oct

Still a damn good octane brew and using MMO will curb that 25% T mix, but if you think youre running 112 pts worth of knock protection youre nuts.

 

I second this..............

My bad I misread the octane I thought the final octane was that for the toulene, I was wrong... DOH

From another post... I mixed up the numbers

https://www.f150online.com/forums/sh...Marvel+Mystery



Xylene (117 R+M/2 octane) & Toluene (114 R+M/2 octane) are the most effective of the commonly available 'boosters' & can usually be found at paint supply stores like Sherwin WIlliams or Duron for $25 ~ 35 per 5 gallon can. The following is the most cost effective 'ratio' for using these products:

1 gallon of booster for every 3 gallons of pump gas

SOOoo for Xylene: (117 * 3) + (93 * 9) / 12 = 99 octane final mix

And for Toluene: (114 * 3) + (93 * 9) / 12 = 98.25 octane final mix

You also need to be sure and add ~0.5 ounces of a top cylinder lube such as Marvel Mystery Oil per gallon of booster. The lubricants normally found in pump gas WILL get diluted by the xylene / toluene & the MMO will bring it back up to spec. AN added benefit of running a xylene / toluene blend is that they are excellent fuel system cleaners & over a few tanks will remove 99.9% of any varnished old gas residue in the fuel system AND carbon buildup in the combustion chamber.

Keep in mind, you'll need to get a re-tune to take advantage of the extra octane, anyone dumping it into a bone stock ride & expecting to go faster will be sorely disappointed.

Thanks Guys great INFO!

 

Adding ATF or something like MMO is fine but not required if you run less than a 20% toluene/xylene mixture.


Glad to see a humble correction Doug C, lotsa forums will flame users with 2 posts who drop tech bombs on the elders

 

WOW the menace man is pretty smart


its alot easier to get torqo, they dont sell it at a paint store though

 

torqo is good additive actually

 

ditto.....

dont run more octane than your tuned for.........its just a waste of money and it will reduce power......unless you like the smell

 

whoa whoa whoa...

I'm not the smart one... that was copied and pasted from a different thread..

I'm not sure who Doug C is, but he deserves the credit, not me.
