I know a guy who work's at a small local airport. I asked him

if I could get some fuel thinking it was good high octane gas. He

told me that the fuel was Regular not unleaded. My ? is what is

the difference. I'm young and barley remember the Regular or

Unleaded day's.<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/happy.gif ALT=":D"> There was also Jet Fuel. He said it was basically

Kerosene. I'm a bit confused about the difference's.

Stay away from that leaded gas... it will screw up your cat. Wait, we all don't have cat's anymore. Nevermind!



Actually, lead was used to boost octane in the old days I think. Everything I've heard lately is that unleaded with the same octane rating is better for your vehicle, cat or no.



Now I'll let the "knowers of all things" correct my misinformation.

Tetraeythel lead was a great octane booster and valve and valve seat cushion in the pre emission era. Actually you can still buy the additive itself from one source that I know of but its supposed to be highly frowned on by the EPA. Older engines with unhardened valve seats can still benifit from its use but now days if you require more anti knock control than super unleaded race gas a variety of octanes in unleaded form are available. Unless you have a very high compression ratio or you are running a turbo or supercharger on high boost you dont need anymore than good old super unleaded pump gas. Leaded gas, I loved the smell of Ethel in the morning.

Damn I got old fast, I remember clearly the days when the question was supreme or regular?... Everybody's supreme was well over 100 octane and sold for about 32 cents a gallon. Long before unleaded <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/frown.gif ALT=":(">

Hey Tenn12, if your looking to just run a little more octane, see if your local bike shop carries race gas for the mx guys. The guys here run 107, so I'll just mix a gal every fill. Do try and stay away from the leaded stuff. It does mess with the O2 sensor. So many of those old cessna's still in the air, that's about the only place you can get regular anymore. Couldn't tell ya if reg. burns any hotter. I can remember a gas war way back when you could buy the stuff for .19 cents, I was making a whole $1.45 / hr. The good old days, ya right.

I don't know enough about it yet, but I'm learning.<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/wink.gif ALT=";)"> Thank's

for all the info. I'm gonna try and find out why the small plane's

use it. And also why the jet fuel is basically distilled kerosene.

I'm just curious.

Tenn12,

The jet fuel or kerosene that you call it has been around for a long time. It is basically low quality paraffin with additives to prevent icing at high altitudes and lubricity additives for internal fuel pumps.

Do NOT under any circumstances be tempted to put this in your bike! It will screw up your engine and injectors! I know of older cars that use petrol initially,to warm the engine up then, switch to kerosene and save tons of money. Fine if it is and old car but, definately not for a high performance engine!!

Avoid leaded as this will damage your cat in the long term and we are talking money there! (providing that it is still fitted)!! Just my 2 pence worth!

Regards

Ted

I dont think any damage would result running leaded fuel if you dont have a cat but I do believe you would develope more combustion chamber deposits but the upside is that your exhaust outlet will develope that pretty chaulk white color we used to all love to see. I also bet your valves and seats would last longer even though they are hardened and can tolerated unleaded. Hell, run it and report back.
