Higher octane gasoline does not burn faster.

I actually get worse gas mileage with Shell. I do better with Chevron or Exxon.

93 burns more completley, thus less unburnt particals, there is really no need to discuss this, i have done it.

higher octane dose not detonate easlily because its more flammable, thus its needed for high out put engines. more flammable=more complete burn

93 will also reduce the amount of gunk deposit on cylinders, and valves of cylinder type engines. because its higher quality


the whole lead thing about being high octane, its fu'kin stupid because you said it your self, IT HAS LEAD IN IT
NO SH*t IT DOSE NOT BURN CLEAN< IT HAS LEAD!!!!!!!

We are talking about pump station unleaded 93.
Prime example of how the de-evolution of man has begun...

We are talking about pump station unleaded 93.

problem with the lead though is you said higher octane burns cleaner. leaded gasoline is higher octane so it should then burn cleaner lead or not based upon your statement of higher octane.

"higher octane dose not detonate easlily because its more flammable, thus its needed for high out put engines. more flammable=more complete burn"
this statement really draws my attention being it is a contradiction. being more flamable would mean it is easier to get it to ignite. think about it object that are very flamable are those that are easy to ignite and generally the more flamable the object the greater the chance of causing an explosive uncontrolled burn. in saying that higher octane gas is more flamable your saying it will ignite a lot easier and is more tempermental which is against what the octane rating is for. again the octane rating itself is for nothing more then how easily gasoline will ignite.

since you are a very smart and once educated as being a gas attendent and want to give facts can you back those facts up? can you explain to me how you are sure the cleaner emissions was due to being higher octane rather then the formulation of the gasoline and chemical additives in the gas? what you are saying by having higher octane gas in itself means a cleaner burn goes against what I have understood from many chemist and automotive engineers. sure there might be a byproduct of some of the additives they use that could help out but it is in no way related to the octane rating itself.

also speaking of your "Test" I have done the same with my own rx7. higher octane gas (91 to be specific) has always made my car run slower, get less miles per gallon (22-24avg using 87oct vs 14-16 using 91oct) and cause more emissions.


also octane does not have relation to quality of gasoline. if you take gasoline of the same type. add some sort of octane booster to batch a but add none to batch b. you will get higher octane. it is all the same gas though so the gas itself is of the same quality. and additives do not always mean cleaner burning either (ie lead).

then about your comment saying of course it doesnt burn clean it has lead in it. whats your point there? it's just one of many additives that can be added to gasoline. and going back to your previous statement HIGHER OCTANE IS MORE FLAMMABLE (atleast according to you) so therefore it will burn cleaner as without the lead in it it would not be as high of octane.

so once again if you are going to state facts, get upset and present arguements that go against everything that is understand stand up back it up and prove your arguements or your "facts" mean nothing.

I read somewhere that bear poop mixed with bear pee burns more cleaner than any fuel.

I cannot release my sources though or they will deny all of it.

lead is a cheap additative that gas companies put in the gas because it was easier doing that than refineing the gas to a high octane.

we are talking about PRESENT DAY unleaded pump gas

have you ever seen those bottles of sh8 in autozone that say "just one bottle and you will pass emmissions, we ensure it!!!"

it works because it boosts your octane to like 95 octane, so you will put out less emmissions, so you can pass test.

i dont want to fight


atleast we all agree 93 octane gives you like 15-25 more horsepower to the wheel

I tanked up today on V-power - 91 octane (they didn't have 93)
They had a sign stating that there is no ethanol added to the 91. This may explain the mileage increase over the usual 5% to 10% ethanol blends.

im about 20 miles ahead of where i usually am by the same point on the needle with the shell gas., not much, but worth the extra few cents for it

I wasn't trying to fight just more or less prove the point. octane means nothing with cleaning just detonation resistance.
those pass smog things are prolly just detergents to clean the injectors and deposits and then something that when it starts to burn creates a lot of h2o. that is more ae chemical reaction rather then octane rating. if you would like to understand that octane doesn't have anything to do with how clean something burns look it up. honest I am not just trying to pull your leg or feed you a line.

and screw high octane for my 7 only cheap for me. actually thinking of switching to 86 as I found a place that stocks it. the 76 accord though only gets premium.

10% to 15% improvement is great! but your mileage sucks. You must drive 100% city...
