I'd like to try this, but I'm a bit confused and my head hurts from trying to read all these pages...I got to about page 20 lol. Now do you pour the MMO/2 stroke oil into your gas tank or somewhere else? Also with gas already sky high I don't want to spend a lot of money....will any 2 stroke house brand oil work (as long as it isn't castor)? And between 2.5oz and 4oz per 10 gallons correct? Also Im running 87 octane if thats a problem with premixing. thanks!

Yes, right before filling up.
I would only use some good quality oil that was designed to be a premix. At least look for TCW-3 designation on the bottle.
Use 4 oz per fillup.
No, unless you use a lot of premix (way more than the 4 oz).

When I go to auto part stores, I start to pay attention to what type of 2 cycles they carry in case I need it. So when I went to get some oil for the 8, I notice Kragen carry these as well as Castrol 2T (2T was discussed in previous page):
Valvoline 2 Stroke Motor Oil
On the back it says meet JASCO FC, don't know if it is synthetic.
Also saw this Valvoline 2 Cycle Oil: Multi-Purpose
This one only has TCW3 no mention of JASCO rating, also no mention of synthetic or synthetic blend.

I don't have links to the threads I read it in, but from what I remember is that if your OMP is working correctly then that is too much oil and you run the risk of fouling your plugs and carboning up your engine.
MazdaManiac on the other hand runs alot of premix because his OMP does not seem to be functioning properly.
In my own experience, my car only has 12,000 miles on it and I've been premixing ever since I hit 1,000 miles. I went one fill up without premixing and the car seemed to gain a little in performance. I only use 4oz a tank, and usually put 12.5 gallons in the tank when I fill up.

? What is the harm to "too much pre mix oil inside the engine?" I know the carbon issue but to you think pre mix really adds to that?
Lets throw this out for discussion.
Also what is best--pre mixing or increasing omp output?
I did a little backyard experiment on an old housing. i drilled out the weep holes to the next larger size---i know i know--what for? Well there was a dramatic difference in the amount of oil weeping through. And it covered a wider area. too look at the drilled one in comparison just with the naked eye--it is hard to tell the difference--so i am not talking about a large increase here.

Have run the 10oz/tank for street and 20oz/tank for track for about 6 months (idemitsu mostly) .
Car runs great . Recently changed the plugs and did not notice any additional buildup .
I would have thought that premixing would be better than increasing OMP delivery because you still have lack of lube to the centre of the housing .

The holes where the "injected" oil enters the combustion chamber. Obviously, at 1 or 2 quarts per 3000 miles, the flow rate is quite slow indeed. Definitely not being "sprayed" into the chamber in any sense. You can cry tears at a much faster rate than the OMP puts out oil. Therefore the term "weep holes" is apt.

OK, Just thought I would let you guys know of a very minor test I have been conducting on AMSOIL Pro 2 Stroke Synthetic PRE-MIX.
I recall way back in this thread about some of you who were concerned about your additives building up in the bottom of your gas tanks (sludge) and the effects it may have on your fuel system and fuel pump.
Over the past fortnight I have one litre (about a quarter of a US gallon) of High Octanes gas in a new/clean/clear plastic bottle.
I added 2 Millilitres (ratio 500:1, or a quarter OZ per gallon)) of AMSOIL Pro Pre-Mix and shook it up, then left standing for 2 weeks, so far there has been NO settlement at all in the bottom of the bottle or any separations in the gas fluid whatsoever.
So, I suggest if you are having any sludge or pump problems I would recommend you use a good quality Pre-Mix.
Briefly on the subject of what ratio's to use.
Idemitsu suggest a ratio of half and OZ per gallon which is about 250:1. (4 Mils per Litre)
IMO I think this is a little too high particularly if you have all the latest PCM Flashes and your OMP is working OK.
Halve that...One quarter of and Oz to a gallon or 500:1 is sufficient.
Will let you know if there are any changes in my bottle, but I doubt it.

I noticed that a few here have stated that Pre-Mixes ADD to Carbon build up, on the contrary...From AMSOIL Website (I have removed their mix ratio's stated for 2 stroke engines...not to confuse)
Saber Professional is formulated with high-temperature detergent additives to prevent hard carbon deposits from forming in hot-operating motors. Saber Professional is “smokeless” and delivers fewer emissions. Saber Professional is recommended for pre-mix where ISO-L-EGD, JASO FD or API TC is specified.
AND
Saber 2-Cycle Oil has excellent lubricity and cleanliness properties to control friction and prevent wear, plug fouling, ring sticking and exhaust port blocking.

Also it should be noted that Idemitsu's recommendation of 1/2oz per gallon is for cars that are not running an OMP.

I hate to get involved in this thread, but....
~5.3 gallon fill ups?
I was putting ~14gallons per fillup which would be ~10.5oz premix per fill up (@.75oz/gallon) plus what the OMP injects. Sounds like quite a bit too much oil, even for an oil burner.
