More HP for N/A from premix
I wanted to share this.
adding 2 stroke oil to your gas decrease the octane rating, thus making a hotter burning explosion, thus more power, plus less wear being you have more lubrication than stock, if you have a working OMP.
This is bad for Turbo engines, as the octane decrease so far it will blow.
I saw one test that took 92 octane down to 87 with a healty mixture ratio of 1:20.
So oil up and enjoy the extra go...

this has been gone over thousands of times and any hp increase if any is negligable..premix is done to get rid of the faulty non working crap omp,s and also to have a cleaner engine bay

Did you just crawl from under a rock?
Indemitsu and Amzoil both attest to higher HP and TQ using 2 stroke oil in your gas.
Anyone who races dirt bikesor any kind of 2 stroke engine, knows this is true also.

It was just an example not for our engine ratios.
The real purpose is to add back the sulfur which has been taken out of gasoline because of the emissions it gives off.
Oil in the gas brings the lubricity back to the gas, and it lowers octane which is something I have seen rotary engine builders/racers of SCCA, as they told me it makes a hotter burn the lower the octane. I was told 85 is about perfect for a n/a with our compression ratio ranges.

Total BS. Show me dyno proof and then I might believe. 
By the time you've premixed enough to dramatically lower octane, you're fouling plugs and trailing clouds of smoke.

Yes, and so does injecting oil into the intake manifold and combustion chamber with the stock OMP.
No
No
Yes, mostly.
No
Typical street rotary engines = 1:150 to 1:250
Typical race rotary engines = 1:100 to 1:160
Typical modern 2-stroke small piston engines = 1:32 to 1:50
Typical dumbass = 1:20
Please phrase your forum posts as a question rather than a statement if you have absolutely no clue about the subject.
That is because several people on this forum don't realize that the octane rating has nothing to do with power on an engine that is not restricted by a detonation threshold.
In other words, with everything else being equal, 80 octane, 85 octane, and 90 octane fuel will all yield the SAME power in an NA 13B.

Not to argue, but I heard something about Mazda using lower octane (I think 83?) gas in the 787B. Would that have anything to do with more power? I would think that the faster burning gas would be better for power.

The 787B was fast because it was painted orange and green.
"The antiknock ability is related to the "autoignition temperature" of the
hydrocarbons. Antiknock ability is _not_ substantially related to:-
1. The energy content of fuel, this should be obvious, as oxygenates have
lower energy contents, but high octanes.
2. The flame speed of the conventionally ignited mixture, this should be
evident from the similarities of the two reference hydrocarbons.
Although flame speed does play a minor part, there are many other factors
that are far more important. ( such as compression ratio, stoichiometry,
combustion chamber shape, chemical structure of the fuel, presence of
antiknock additives, number and position of spark plugs, turbulence etc.)
Flame speed does not correlate with octane."

Doing maintenance to increase HP to an amount that can be measured or even spoken of is rediculous.
Changing the oil/filter and air filter or fuel filter, if they are not already clogged, won't help much on an n/a
