Now if I ever get the RB OMP modification, then I may shy away from premix.

OK, I keep reading about premix and have a few questions.
The earlier rotary used to burn alot more oil than the renesis (I used to have an RX-3 in 72). Why the concern of carbon buildup if a little more oil is injected? I have 750 miles on my 06 and will take it in for the reflash when the dealer is ready. Until then, what would be the problem of just using the regular motor oil in modest amount mixed in the gas for lube until the flash? In piston engines, upper cyl lubrication is well known for increasing the life of the engine but with the life cycle of most engines, is not used much. It is usually just mixed into the fuel. If synthetic oil is a concern for Mazda, what is the advantage of using synth two stroke premix?
In other words, if reg oil is being injected by the MOB then why couldn't I use reg oil to mix with fuel?
Thanks in advance for any replies.

Mazda uses motor oil because its easier for the consumer and cheaper then adding a 2nd oil sump. Even with only 1 sump, many owners still wait for idiot light reminders.
Motor oil sucks as premix. Use 2-stroke oil or an UCL when adding supplemental premix. You don't need pour point depressants, viscosity index improvers, and various other crap(TBN/TAN & AW/EP additives) in your fuel based lubrication.
Most certified 2-strokes will also clean. Locate the MSDS for the brand you choose. Besides oil basestocks, most are made with 1/4 or more various distillates and chemicals which help prevent and remove carbon buildup. These are the same chemicals are used in FI cleaners. Stick with API, JASO, or NMMA certified 2-stroke oils.
nycgps, good catch. About time Mazda admits that the fuel is the cause of the carbon issues in a rotary. I've run 2-stroke engines up to 25:1 without carbon and never could understand why everyone blames the motor oil when every issue that I've seen was caused by pig rich A/F ratios.
Lucas makes 5.25 ounce UCL bottles. This is perfect sized bottle. Buy several, use the UCL, and then refill without whatever premix oil you want. Other reusable bottles are the ones with ounce measurements, like Sta-bil.

Someone needs to make an external sump adapter for the Rx8.

well the amsoil is ISO-L-EGD, JASO FD, API TC certified. I figure I will be only using this when I autocross and go to track days. upon using this calc http://www.speed-sports.com/more/oil.html with a 300:1 ratio the 3.5 ounce bottle will be perfect for 8 gallons of gas.

also, would pouring in about 4oz of Lucas UCL along w/ the above 600:1 ratio of amsoil be ok or overkill???

Ok.....
I would consider the two as seperate items, so 400:1 premix and 400:1 UCL would be fine, (or would that now become 399:1? 
) The lower rate reflects that your tank wouldn't be bone dry anyway.

I quickly looked on lucas website and couldn't find the ucl that you are talking about. can some point me in the right direction? also would the just the 300:1 of ucl be ok for regular fill ups?

Lucas UCL is actually their fuel treatment.
http://www.lucasoil.com/products/dis...tid=2&loc=show
When keeping the stock OMP, I don't see the need of double dosing(UCL + 2-stroke). Grab one, the other, or mix the two. I see it as overkill.
400:1 premix + 400:1 UCL= 200:1, which is enough not to even need OMP injection.
This is why I like the 5.25 ounce Lucas bottles. Add your 3.5 ounces of 'lubricant', and top off with 'FI cleaner'. This will provide the supplemental lubrication and cleaning that you need.
I can't vote in the poll. My vote if for 'FLASH + PREMIX'. Even with the reflash, I expect it to still be oil lean.

All this time I thought you guys were disabling the engines oiling system to run premix. I guess not. Lucky I have been using Lucas fuel treatment w/top end lube.
Has anyone tried Redlines 2-stroke oil?
Also seems like the rule is to use about 3oz. of oil to 10gal of fuel no matter what the oils recomends mixing ratio is (50:1, 100:1 ect)
