Fuel grade question

Think about this. . .
Super has a higher resistance to self ignite; it's less flammable.
Regular cheap-o gas has the same energy, but ignites more readily, such as on a hot spot.
Diesel won't burn if you throw a lit match in it, but burns well under pressure. And has more energy per volume.

So, if you blended 5% diesel into cheap-o gas, do you get a fuel that ends up with a higher flash point ( higher octane) AND more energy? The trace oil would also help seal and lube the rings and valves?

(kids, don't try this at home. . . )

 

If only I had a working gas tank to test that on the non-road worth seca...

Anyone with a doner tank? I'll totally blend some diesel in... O_O

 

I was running high octane and on occasion having trouble starting the bike. I read somewhere that the higher octane stuff is harder to ignite, hence may cause starting trouble. So I have switched to the lower octane/ cheaper stuff and since then I have not had a problem starting the bike.

 

Two months ago everyone here was saying GO PREMIUM its better blah blah blah... then I do a little research into octane etc, realize now that it was all B-S. lol...errrrrr

I'm gonna go top off with some good old ghetto-gas and see how it runs

 

dpawl31, the lead substitute is for lubrication since are bikes don't have catilatic converters or O2 sensors there's nothing to harm by adding it(at least I didn't think so)

As far as the flames go its not like I'm shooting 3 foot fire balls out the exhaust its just a little flash of unburt fuel right after letting off after a good drag race or nice sweeping corner. I don't have the restrictive stock exhaust so I have it jetted a little rich on the top end.

 

I don't know enough about lead to say anything, but I would think the bike is designed for use without it, and it could be excessive and hurt the motor. Just my guess.

As for the flames, all I did was explain what causes it, and with a STOCK exhaust system and jetting it should never happen.

 

I had a '64 Corvair that I had to add liquid lead to because of the age of the vehicle. Vehicles now are made for unleaded gasoline. They made the valve seats harder so there was no need for the lubrication the lead gave in gasoline.

Paint hit what my boyfriend was trying to tell me. So I figure why not put the cheapo stuff in it.

My van on the other hand hates 87 and I have to put mid-grade in it. The owners manual even says 89 octane or higher.

 

As cars age and the valve wear, you up the octane to avoid knocking. (detonation.)

 

I started out using regular (87) and it ran fine, but it had a funny vibration at certain RPM's. I was once told that in 1981 regular gas had a higher octane rating than it does today, so if you run mid-grade (89) it will be closer to the original fuel. I tried it, and the engine vibrates much less than it did. Sometimes it starts a bit hard when warm, but overall it runs very nicely. Your results may vary.

 

This is interesting because my bike too has a funny vibration around 5-6k. It's not real strong or anything, but the bike is so smooth everywhere else that even a small vibration is noticeable.
