I know ether is the main ingredient in starting fluid and some pretty volatile stuff. You need not explain anymore if you don't want to, but I would like to know more about this if you have the time.
P.S. AND NO, I'm not thinking of dropping mothballs in my SRX 700 gas tank.

I remember a couple years ago one of my know-it-all guys here in town ran HEET in his sled, I don't know for sure how much he put in, but teh sled sure didn't last long.
It was a combination of ether and napthalene that produced the "octane boost" that you got from ading mothballs.... I don't think they are as volatile anymore,, although I haven't dumped any mothballs in a fuel system in about 35 years !!!
I did a post on those little bottles of heet YEARS AGO... You already have 10% methanol/ethanol/alcohol of some sorts in your fuel system already... 128 ounces in a gallon.. 10% of 128 is 12.8 ounces... So you see,,,, you already have 10+ bottles of HEET in your fuel system.. Will it burn down your sled because of the alcohol.... QUITE THE OPPOSITE will happen... Lets see if I can explain this.. OCTANE is the engines ability to RESIST DETONATION.. The higher the octane,,, the COOLER the cylinder temperature (flame kernel) and the BETTER it resists detonation ( opposing flame kernels or flame fronts ) ... Please bear with me,, I haven't been to school since the EARLY 1980's... HERE WE GO..... Gasoline ( pump gas) burns around 18,000 BTU's and ALCOHOL burns around 6000 btu's... Considering that an internal combustion engine is nothing more than a HEAT PUMP,,,,, the amount of BTU'S used is directionally proportional to the amount of BHP ( horsepower) that the engine creates... IN THEORY ( and like I said a few sentences ago, it's been awhile since school) it takes THREE TIMES the alcohol to create the SAME AMOUNT OF POWER as gasoline.... Gasoline manufacturers,, in the wintertime use other chemicals to PROMOTE atomization ( remember,, LIQUIDS CANNOT BURN !!!) and in the summer,, they have "tricks" to resist atomization... Fuels are tricky...There are oxygenators on the market that will DESTROY your engine if your not careful... First,, you have to understand that it's the NITROGEN (inert gas) that ACCELERATES and SUSTAINS combustion... NOT the oxygen.. The water ( H2O) actually RAISES octane by cooling the cylinder and SLOWING the KERNEL down IF YOU KNOW HOW TO INTRODUCE the water as a vapor under substantial presure.... Water injcetion used to be a HOT TICKET and people were putting little "stills" on their cars in the 1980's... I gotta go do some work now.. We'll talk later...
ALCOHOLS ABSOLUTELY HATE lubricants like TWO STROKE OIL... The alcohol actually destroys the "oil film" and promotes FRICTION.. STUFF WEARS OUT A LOT FASTER using alcohol as a fuel.. The DRAG racers that use e85 and methanol have to change their oil CONSTANTLY.. They have to DRAIN THEIR FUEL SYSTEMS after every day at the racetrack... Rubbers have EMMOLIENTS (lubricity) that keeps them from drying out and turning into a powdre... ALCOHOL removes these emmolients and DESTROYS rubber ( lubricants too).. SYNTHETICS are a MUST when using ethanol or methanol blended fuels !!!! ( not amsoil either)... We'll talk about BEAN OIL later....killerklown said:

when your talking about HEET, are you talking about ISO-HEET? My dad's ran that in his stuff for years. About 1/4 bottle to every tank of sled fuel, not adding during the ride for the day, but always when getting home or just before leaving. Never had any engine failures in 30 years...
Heet in the little YELLOW bottles.. (methanol) Heet in the red bottles is isopropyl alcohol.... No need to waste your money with todays fuel.. If you have WATER in your fuel,, it will FREEZE and turn into chunks of ice and will not harm your sled.. Water turns into a solid at 32 degrese F.Spinner18 said:

that ain't all true! what about the guy that keeps their sled in a heated garage or when the temp is going above and below freezing .the chunks of ice melt and can then get sucked up and pumped in to the carbs and as you know these carbs have no water traps on them so the water sits there right around the main jet waiting for the temp to drop and refreezes then the next time you go for a ride the first time you nail the throttle and your main jets are partially or totally covered in ice your pistons pour out the exhaust and your done. been there dun that!nosboy said:

My Son and I, yesterday ran over 100 miles at or near WOT on pump fuel. The SXR oil is Yamalube. The Viper is running amsoil Interceptor. In the fuel I add Sta Bil Marine formula at every fill up. Stock jetting, Stock engines except for milled head on the SXR. I know we are running 10% ethonal. I would have thought if we were to have a problem it would have shown up. I think the stock jetting is rich enough to overcome the detonation problems and the extra oil lubes everthing real nice. Oh, the carb heaters were both on 100%. We were in deep snow basically the whole time. Al

The minimum octane requirement for both sleds is 87, correct?
