110 octane fuel

Re: 110 octane fuel

but is the lead in it good for the values

I assume by "values" you mean valves? Two stoke engines don't have valves.. You need to do a little bit of studying of two stroke engine theory if you thought otherwise.

its actually 108 octane i figured more pure and might help with my idle issues

Higher octane does not equal higher purity, better gas, or "premium" (as the oil companies like to label their pumps). It's just as clean or dirty as any other fuel, which all depends on how it was refined, and how it's been handled since it left the refinery.

Higher octane doesn't mean more power, more bang, better performance, or any of that your thinking. It's associated with engines that produce more power, more bang, and better performance.

Diesel fuel has more BTU's per gallon than gasoline. You could pour that in your tank in hopes that your engine will make more power, but I'm sure you know (or at least I hope you know) that pouring diesel in the tank of a gas engine results in poor-to-no performance. Why? Because the engine wasn't designed to use it. Just like your 1971 low compression engine wasn't designed to use anything more than 87 octane gasoline.

Ok thanks for info

Re: 110 octane fuel

Just wondering put two motors on dyno same motors one with 87 octane witch is really like 85 then other motor has 110. Mixed half witch will bring it to 103 octane that the one with more octane wont respond faster and top ot at higher rpm

Re: 110 octane fuel

lmao. please tell me that you are adding oil to the gas and that you will read how a 2 stroke works. If you want more power drop the 30 year old motor and buy one that is higher hp. Its a 40hp why do you think you can make it a 45hp by adding wonder gas (why do you think 45hp would be any better)
The new unleaded with ethenol is going to eat the rubber parts of your motor if there original so go ahead and spend 10 bucks and change out the seals in the carb and the fuel line now before its a problem then fill it up with cheap gas add the oil and the motor will be happy.

Re: 110 octane fuel

I useually make most gaskets myself out of beer boxes works pretty good and saves money i wasnt really tring to get more power just wondering if it would smooth out with different gas and on oil i always add a little extra for luck i say it has same original seals i could soak them in brake fluid and that should swell them up i dont plan on rebuilding carbs ill let yall know how much better or worse it runs on the wonder gas thanks

What part do you mean is dum everyone has a opinion and the one you think is wrong could be right

Re: 110 octane fuel

Now what are you talking about

Re: 110 octane fuel

You guys can lol all u want but when you get stuck somewhere without all your electrical equitment and nothing to work with you will understand what im saying when a oldtimer comes up and fixes with what he has everyone has tricks and ways of doing stuff and you dont know if it works till you try it if your to scared to try tricks secerets from oldtimers cool but dont laugh at me when i know what could work

Re: 110 octane fuel

i said sry.

"but when you get stuck somewhere without all your electrical equitment and nothing to work with"

I read the post where you lost your volt meter sry about the bad luck you had with that. They realy should put a warning label on the high side of the coils so more people dont blow up there meters.

i have a leak on my tilt and trim so i might try the hydraulic fuild trick to see if the seals swell and stop the leak. thanks for that idea

 

[ilovevintage81]

Re: 110 octane fuel

Yeah i lost voltmeter but i wraped fuse with aluminum foil and back working and if you have dried out seals brake fluid will swell them up i havent read any of your posts and dont plan on it i hope your helping people out thats all i try to do find posts with zero and try to help give tips doesnt matter if 10 people say to do something its right. For you im not dum im learning and i do listen doesnt mean i agree and i guess your buddys with moderator too thats okif i have to go to yaho answers or ask .com i will but have a nice day

Re: 110 octane fuel

To the point..
1) Av gas does not have lead as of 1990
2) Av gas makes a 2 stroke run better as the added oxygenators lean the air/fuel ratio out. That why when you put it in a auto the exhaust pipe is clean due to the lean burn..
3) You can run Av gas or any octane over 100 in a 2 stroke , just need to upsize jetting for it..

Re: 110 octane fuel

Hey faztbullet ill check on that ive been readingabout the fuel in 2 stroke bikes ive watched on you tube about changing jets cause i had a mopad and got it running better after getting rid of the oil pump mix and using premix i was only going to use like 4 gallons in a 9 gallon tank my engine is old but thanks ill look into that i think the kind of gas i was going to get is unoxgenated but i will definitly check on it cause ill have to rebuild engine sooner or later and after boreing i could always put biggerjet maybe it will boost to 45hp thats what my boat is rated

thats not fully correct. the brand mainly sold today is avgas 100 LL , that stands for 100 octane and light leaded. so its not lead free.

btw- what a funny thread !

And 100 LL still contains more lead per gallon than regular leaded auto gas did when it was sold. All the various industry groups (engine manufacturers, refiners, airframe manufacturers) have been working for several years to agree on a replacement, but so far unsuccessfully.

btw- what a funny thread !

No Comment. :facepalm: opcorn:

Re: 110 octane fuel

To chinewalker the wierd thing is when i had the OLD GAS LIKE 5 YEARS OLD it was idleing just fine i could turn all the way down and it would still run barely putting then next day the problems started so i got new gas and didnt help thats why i think it has to do with points or coil ive adjusted fast idle and low about a turn and a half out but i had running so smooth the day before u couldnt hardly see motor move it wants to back fire or u can tell one cylinder isnt getting fire if i rev up high then let off fast it will do that. Takes a sec to smooth out does this motor have timing advance when reved up i know i should start new thread

Not trying to sound stupid or anything but did you ever clean the carbs, fuel pump, and fuel hose after running that old gas through it? That alone is enough to cause your idle issue if you haven't. Just think about all the garbage that old gas just carried through the entire system. Something to consider. Best of luck gettin her running good.

Re: 110 octane fuel

No the old gas was good my other engine runs fine on it but this is definitly a different thread i was just wondering if anyone ever used it the 110 octane they used it in the rotory engines but i guess the lead wouldnt be good for my piston walls but with all the info im learning
