You know how the Winter season brings the worst of our car? In the last three days I started having problems starting the RX-8 if it's very cold outside. The same if one floods their engine, I don't go through the procedures as the engine turns over after a few starts.
I don't go out for short drives and I've always made sure that the engine's warmed up before going out. It feel like it's fuel starvation or bad coils, so I've hold off premixing with the assumption that my fuel pump/line/filter or CAT could be clogged. What ever it may be, I'll have to check all these next week since the car hasn't preseted any CEL.

I am using Amsoil Saber Pro, which says it is designed for 100:1. So I am thinking of 1 oz every 1.5 gallons. That way I know the people who produce it say it is effective. (I am still injecting 4 stroke oil also until the engine warranty is gone.)
Most 2 stroke oil is designed for 50:1, saying you would need 1oz every .75 gal to fully lubricate a 2 stroke engine. I would think it may no longer be very effective at 200:1. Not arguing, just putting my thoughts together out loud.
Is my math right - you put in 1 oz in 3 gallons (US)? (200 oz/64 oz per gal = 3.13)

60litres @ 200:1
divide 60 by 2 and add a zero = 300ml
Take your point about 2 stroke but a rotary is not one . I have talked with a few race teams about what they use and it's always around 150:1 with no OMP being used .
My reasoning is that 200:1 is a little less but I'm also using OMP at 50% of it's normal so works out about the same . Seems logical to me
I am old enough to remember when the US was almost smart enough to convert. Now you don't even hear about it. Hmm, what does that say about us?
I hear you that it is not a two stroke. My hypothesis has to do with dilution and at what level does it lose its lubricating effect.
Noone has explained to me about the Amsoil 100:1, but I am guessing - oh, I should say "surmising" it is really special stuff! http://www.google.com/search?q=surmi...=1&safe=active
Thanks for the quick answer!

If race teams use it at 150:1 then i know that dilution must work . And 200:1 is real easy for me to work out . I don't get too **** about it .....
This is why US should change to metric LOL

I have only been using about 4oz per fill (so i think thats like 110ml)

One quart is 32 ounces X 4 = 128 ounces per gallon.
The recommendation of 200: 1 means 1/2 percent.
So whatever ounces of gas, add .5 percent or multiply x .5 on a calculator.
Example : 12.3 gallons x 128 ounces + .5 percent = 7.87 ounces premix
The plugs are less than a 1000 miles. I have not changed the wires and coils due to insufficient funds. As soon as I have more, I will! Anyway, I suggest installing an oil catch can. For some reason, when I started premixing my car threw a CEL due to oil overflow and interfering with the MAF sensor.
That's the last time I trust my wife!
So to do Brettus's 150:1, I would put in almost 1 oz per gall. I do that at the track, but haven't in an regular driving. Hmmm.
64 oz per gal

?? This makes no sense what so ever.

I know there is a lot of info for new owners to absorb but it still amazes me when I see post like that. I don't claim to know everything but to think someone started premixing without fully understanding the concept is scary.
It's made by Citgo and Has a Jaso FC rating so it should be okay. Seems to be synthetic but I cannot find a product data sheet or MSDS sheet on it.

And I do buy the mineral version (apparently not... it seems to be semi-synthetic: Semi-Synthetic)

Here I found the datasheet:

Another thing I'm wondering... 4 cycle oil doesn't burn well, and can leave carbon (or even worse get coked up), especially dirty oil from the crank. This could very well be the major contributor to carbon build up in the Renesis.
Now, I'm thinking, if you run Idemitsu through the Sohn adapter, premix with Idemitsu, and use the Cobb AP to lean the mixture out, why would you even need a cleaner? I know you can change the OMP rates through the AP, but it just seems like it would be a better idea to premix as well, since you would get the entire combustion chamber with the premix.

So far, I've gone by the general recommendation of 4 oz. of premix per tank for regular commuting in my Series II ...
This works out to about 8 tanks per quart of premix.
Since I'm getting about 340 miles per tank, this adds up to about 2700 miles per quart of premix.
Coincidentally, I'm getting about 3000 miles per quart of motor oil.
So, I'm roughly doubling the amount of lubricant going through the motor. With little other empirical data to go by, and considering carbon build-up concerns, I don't feel like I'd want it to burn any more oil than that.
