moped fuel=speed?

unknown knight /

I've heardthat your moped runs better if it is runni g on aviation fuel from thenearest airport...even though it is like a dollar more is it worththe quality..... If any body out there runs there moped on aviation fuel let me k ow if I should start useing this fuel

Thanks

Re: moped fuel=speed?

aviation is just another word for high octane gasoline. Its not worth the money.

Re: moped fuel=speed?

A fuel with a higher octane rating than necessary might even slow you down. The higher the octane number the slower the flame propogation is in the combustion chamber. On a moped with such a small piston diameter the high octane stuff might make the cylinder firing too slow.

If your engine is not pinging, you don't need it.

No no no and no. Higher octane fuel does NOT make for better performance. It only allows you to run at a higher compression ratio without pinging. If you haven't seriously modified the engine to the point where it will no longer run on pump gas, there's no need for high octane fuel.

Re: moped fuel=speed?

If it's a dollar more then it's probably 87 octane if you want 100 octane it's running about $7 bucks a gallon. There is no advantage to running avgas. The 87 and 100 has NO ethanol and 100 still has lead, fewer and different additives, and of course better quality control.

Re: moped fuel=speed?

Listen, its as simple as this. higher the octane the better for your engine. Its burns better in the motor. If anybody knows anything about racing and performance, theyd know this. The bigger the explosion ( pistons ) , the more power. The more octane, the more explosiveness. You wont go SIGNIFICANTLY faster, you might not notice anything. I use sunnoco 94, and V-Power, and my motor runs smoother then regular gas.

Re: moped fuel=speed?

smoother cuz it doesn't have all the junk in it like ethanol (nother rant). not because it needs a higher octane, unless u have done some crazy junk.

Re: moped fuel=speed?

If you knew anything about racing and performance, you'd know that it isn't an explosion that occurs in the cylinder, it's a controlled burn, and if you're having 'explosions' in your cylinder on a 2 stroke engine, it's having detonation issues, and you're in serious danger of seizing.

The only reason to run high octane gas in a moped is if you've modded it so that the compression ratio is to the point where it will preignite unless you run higher octane gas. As silverfox said, the higher octane actuals SLOWS the burn to prevent preignition.

Re: moped fuel=speed?

Yeah dont listen to a 16yr old Jersey kid about your gas. High octane does nothing for a stock or near stock engine.

As John said, if you know anything about engines you know that no explosions are happening inside your engine if it's running right. No explosive force or shock wave is moving your piston...what moves the piston is air heating up and expanding, and it just so happens that the best way to effect that is to burn gasoline in the cylinder to heat that air. No explosions, just fire.

If your compression ratio is so high that your mix is pre-igniting, which is when the mix is igniting from a source other than the spark plug and so throwing off the timing. A higher octane will burn slower and so reduce or eliminate pre-ignition vs lower octane gas given the same engine conditions.

cbonez....I lol'd hard reading your post.

try not to help people when you have no idea what you are talking about yourself mang.

LOL...explosiveness. Click the link below Cbonez...

http://en.wikipedia.org/wiki/Octane_rating

Or keep reading if you want the short version.

Octane is a comparison rating. The easiest way to explain it is that fuel with an octane rating of 87 is 87% as resistive to autoignition as pure octane. Fuel that has a rating past 100 is better at resisting autoignition than octane.

The whole point is that the lower the octane rating, the more likely you will get ignition during compression. As the piston rises, the air/fuel mix in the chamber compresses and the air temperature rises. Fuel with a low octane rating will autoignite before the spark ignites it. This is what creates "knock" in an engine and wastes fuel and power. The only vehicles that see a benefit with higher octane fuel are vehicles with high compression engines (sports cars, some aircraft).

Re: moped fuel=speed?

What does me being from jersey have anything to do with what were saying. Your from some gay indian named city in Tennesee, and your moped if that even is what it is, looks like my bike from when i was 10 with a lawnmower motor on it, id be embarressed to ride that shit. With a bike like that, you shouldnt even talk about gas, that probably runs on shit.

ahhhhh...the sweet mating call sound of the rare New Jersey Dimpleshits in his natural habitat.

oh...and if that dudes ped runs on shit then he will be a billionaire tomorrow.

Re: moped fuel=speed?

Ha, I love when posts turn into hate speeches.

Re: moped fuel=speed?

he uses V-power.....

am i the only person that thought this was funny?

Re: moped fuel=speed?

Gunther McCilicutty /

no..it was funny..but in a pathetic sad kinda way. Not really funny haha...but funny peculiar

Re: moped fuel=speed?

i was thinking more chauvinistic potty humor.
