For daily driver there really isn't any, given that current PCM flashes already meter add'l oil to ensure optimal rotor seal (which is what pre-mix augments). Remember that a rotor doesn't have the sealing rings of a conventional piston and therefore precise tolerances, augmented by a thin layer of oil, seals a rotor.

However, for we who pamper our machines, it does give peace of mind, especially with spirited driving. For track use it's a very good idea to pre-mix.
For everyday/spirited driving 4 oz. per tank of gas is plenty.

put in 4 oz per tank if u want ur engine to last.

interesting to know that 09's are getting 1 additional oil injector.

*sigh*

better sealing ? better lube ?

Search anyone ?

The think the problem is more like the oil cant even get to the center of the apex seal. premature wear can occur.

One of the reason why Mazda add another oil injector to the coming 09 motor right at the middle.

I mean our engine will work but, not going to last too long if it does not premix.

is this ever going to end? lol

5w20 most of the time .... 5w30 in the heat of summer when temps are in the 90s. my economy does suffer with 30 but at least I know the engine wont suffer.

can anyone agree on that?

ps ... i always use that lucas crap ... i believe it does help.

Ive been premixing for the last 2 tanks with lucas non synthetic two stroke. I got it from O'reiley's and I went from bairly getting a hundred miles to a half tank to 104 miles today. Keep in mind as I have found that if you try to baby this car to much to save gas you wont. I normally shift between 3 and four grand and thats ok Ive found but from what I have read on the site its good to rev it up to 7 grand every now and again. Ill baby it and every so often ill drive it like I stole it.

9K-RDLN

Has anyone that premixs had oil on your air filter. I havnt gotten an intake and went to take out the air fliter and it had oil spewed on it from the throttle body. It was if every time the throttle body opened to breath it was spewing oil onto the filter. Is this normal if you premix?

nycgps

iTrader: (1)

Dude, someone overfilled ur motor oil.

Oil in Filter = Motor oil overfilled by morons, that could be you if u did ur own oil change.

What does that have to do with Premix ?

Get ur facts straight before u try to blame something.

Seriously people, Please read and search b4 u post ur question.

swoope

iTrader: (5)

no relation to premix..

over fill of oil. or improper fill of oil.. both involve poorly done oil change...

9K-RDLN

I wasnt blaming anything dude I was asking a question. Simple as that, being that I have no experiance with a rotary engin. No need for you to be a dick about it. I would love to read and research this kind of ****, why dont you be a huge help and tell me a few places to read. Or you can not be a dousch and read and see that I was doing research and asking a question.

You could have stopped there and not have been a dick.

In fairness though, 9K RDLN...read the stickies at the top of each area.

in case BOTH of u never notice, I DID answered 9K's question.

U guys are pissed cuz u knew I was right about 9K never searched.

it has nothing to do with Rotary or whatever, its you, 9K, and ur 3.8 GPA does not impress me, my cousin has 4.0 and she is a doctor, my GF has 3.85 with CPA, I never finished college but Im making more than they do. so what are you trying to impress me with ? ur lack of knowledge ?

To learn, u gotta work on it, not just *post & wait*

nycgps

iTrader: (1)

Those who hate know it all cuz they know nothing at all.

Im not know it all, but obviously u're part of the "know nothing at all"

Its alright man, we know that u know nothing

Oil in filter has something to do with premix ... priceless.

not to mention, u came up here to just reply to this ? Wow, U have a life there, MR. 3.8 GPA

Pissing contest!!!

Back on topic and to the OP, use caution when choosing a pre-mix oil. There has been some talk here that some of the more commercially available 2-stroke oils are more rapidly clogging fuel filters. Lots of the oils you find at Wal-mart and the like have dark blue dyes included, which apparently turn to black sludge in your fuel filter. I use Idemitsu that I ordered from MazdaTrix...4 quarts cost me roughly $30 shipped, and it contains no dyes. I've been using it for over a month and am still on my first bottle, adding 6oz. per tank.

Prior to pre-mix, I was getting a nasty rattling on acceleration, sounded to me like detonation, but could have been intake ports rattling. With pre-mix, I've seen a very modest increase in MPG (+1mpg) and the rattling is almost completely gone. I can only hear it now if I fail to give enough gas when releasing the clutch on launch. The engine seems to spool up more smoothly than before and sounds less coarse as well. Another thing I've noticed is that the classic rotary "whup-whup-whup" exhaust sound at idle (typically heard on 3 rotor engines) is quite noticeable since I've been pre-mixing. I may be imagining it, and if I'm not, I've no idea what the hell that means, but the car seems like it.

How much oil would you need to put to get something like that to happen?

nycgps

iTrader: (1)

about 1/4 quart more than what the capacity is will trigger this event.

its nothing scary really, if u catch it early and clean the stuff out b4 it gums up that is.

Jonathan11

Question, I ordered Idemitsu premix from Mazda Trix, however i see that it says it is synthetic. I do not have the Sohn Omp and would like to know if it is okay to put synthetic premix in my car. I thought synthetic was a big no-no for rotaries.

alz0rz

iTrader: (41)

uh.. there we go again.

synthetic is fine.

read your own sig.

i've been premixing Idemitsu and using synthetic Royal Purple motor oil for the last 10,000 miles - absolutely no issues.

Jonathan11

lol, yea my sig...Just thought I'd ask to clear up some uncertainties that i had. Thanks for the input, I figured since I use regular motor oil i might as well not add synthetic premix would kind of defeat the purpose.

04RX8man

you must remember that premix may b synthetic but the point of it is to burn....supposedly the reason y synthetic is not recommended(at least what i got from it) is that it does not burn as good as regular unless it's an oil that is meant to burn like premix!!!

Search, Search, Search

GaMEChld

yeah. SOME synthetics don't burn as well, so make sure whatever you use is tried and true.

SpIcEz

What synthetics dont burn well?

Even on this website, even those who use premix, even those who use synthetics still beleive in the myths that are spread around...

unbeleivable

GaMEChld

I don't know, I seem to recall people saying Mobil 1 didn't burn well. I'm not certain though. I feel like I got that from rotarygod, but cant say for sure. Either way, I'm using Royal Purple, and thats just fine. I also premix Idemitsu with FP+
