I will add some caution along with Devon here, your standard labeled products at your local home store is problably not what your looking for. Maybe years ago you were able to get high quality stuff off the shelf but since every industry has been trying to make their products cheaper and charging more for their products, you might not know what your really getting. You need to be carful of what your purchasing and mixing. One would have to research the grade and purity of the products mentioned from the chemical manufacturer of your choice. There will be a difference in quality and purity between your less expensive clean up / thinning products vs professional/industrial grade products.
5 gal of race gas is still cheaper than Toluene. At 12.00$ a gal is what it being sold here from Sunoco. You can find race gas at some race shops at least here you can and it is about 8.00 a gal. The track sells it too at about 8 a gal. At least it was the last time I ws there. That toluene is some very strong stuff it will swell rubber and eats just about anything it comes in contact with. I would try to find race gas instead of using this. I might try a gal in 20 gal of gas but that would be about it. You probably can get this stuff at a printers supply house. A lot of shops are trying to get away from this stuff it can get to you. ring ring. It will mix with water some so it will get the water out of your tank and it dries in about 2 sec when put on a rag. About the same drying rate as Acetone and that crap is bad for you too. There was something about AV gas that was not good for the car but I can't remember what that was.
He is right about that we get the industrial grade stuff for printing but even they have been getting away from it since now they make NO Toluene Type Wash. our Alcohol is 99% you usually can't get this at the store, it is 91%.
The place I work at now they call it type wash (toluene) but it don't come close to what it was back 10 years ago.
Avgas is bad for newer cars because it has lead and will foul o2 sensors and plug catalytic converters, so I wouldn't run it in anything mid 70s on up. Our older stuff I haven't heard any reason not to run it
Toluene has an octane rating of 114 (RON + MON/2). If you mix 2 gallons of Toluene with 18 gallons of 93, you get 95.1 octane. That's assuming you can get pure Toluene. The question also is, how does the price compare to a gallon of Race Gas rated at 114 octane?
Your post lead me to this site; http://www.whitfieldoil.com/www Looks like 116 is less expensive than any toluene I have found, they have a bunch of other choices as well; http://www.whitfieldoil.com/www They have dealers all over the country but unfortunately not one close to me! The search continues............... Derek
Larry look at the info........for a 3.5 increase in octane you would require 6oz (1.2 oz per gallon) to treat 5 gallons of fuel, providing you are using 94 octane, that's a bump to 97.5 (1 bottle is 32 oz) 10 oz would bump 93-94 up to around 100 octane for 5 gallons. I've run this stuff for years on the street and I believe this stuff is the real deal. I run 30-32* locked on the street and never had any detonation/pinging issues. Not to mention, the exhaust smells like race fuel with this stuff mixed in. Seems to work for me, but maybe I'm a believer in snake oil At the track, I'll only run C12, then bump the timing.
No, what I am saying is they claim points of octane. That is 10ths. To go from 93 to 94 is one octane number. One point is going from 93 to 93.1. That is my understanding of it. Their advertising does nothing to clear that up, that's on purpose IMO.
Yes, if it were not, no one would need to buy race gas I dug up a bunch of GSCA Extra articles on octane boost. Going out to dinner now, I'll try and post them later.
And some info on Aviation Fuel, and a test of Lead Supreme 130 (same as Octane Supreme?) from back in the day. (Nov/Dec 1990 GSExtra)
Interesting last line on that first article of the post above, Larry! Having run Avgas for years, and VP a few times, I can tell you that the Mach 1 does seem to "like" the VP better, but the Avgas is difficult to beat for the price and meets my needs for everyday driving. I don't know if the VP made any actual HP difference or if it was a mental thing. Both provide the pre-ignition protection in my 13.5:1 compression, 552" engine. I can run my timing up to 34* BTC with a 50/50 mix of Av/91 non ethanol or VP/91 non-ethanol. On straight pump at my 3400 ft. altitude, it's a pinging monster at anything above 28*, and I have to tune super rich at that. I wonder if the colder burn helps even though it's lower octane than the VP. The guys at the airport tell me that the Avgas I get is between 100 and 106 octane depending on the batch, so I usually figure on the safe side at 100.
Who authored this article? They need some help. In piston aircraft we only make and use max horsepower in takeoff mode while on the ground and for a short period of time after lift off. His statement that being on the ground affects avgas' octane rating makes me want to laugh. During the takeoff run on the ground and right after lift off is when you need the detonation protection. Yes 100 low lead is leaded fuel and yes it is equivalent to more than 100 octane when rated like auto fuel. Years back I posted about this issue based on a question and answer I had with Ben Visser. Ben was head of Shell Oil's avgas division. Another benefit is that avgas is made to be stored for 12 months while auto fuel is made for 6 months storage.
Jim, Richard Lasseter. Send me an e-mail and I'll send you the whole page. I clipped out the paragraph about Aviation fuels.
