^I think Zoom44's interpretation is at least equally likely as the dealer's. Until somebody puts a straightedge to the seals and verifies the wear rate is much greater than is typical for a 15k motor (does anybody even know what is normal wear for a 15k motor?) I think it is speculation to indict MMO.
I was just giving out the information i was given. My dealer opened up my engine and i do not know if they were supposed to or not. I can PM the dealer name to zoom to see if they are on "the list". Yes this is speculation but i figured it should be shared anyways as most of the threads regarding premix and oil are surrounded heavily by speculation. Personally im not going to use MMO anymore and was just sharing my story.

One way or another, it does seem to keep the motor clean!

He was simply giving his opinion and i personally find him to be credible. He called me after opening the engine and KNEW that i had ran something through the engine. Up until that point, I had not told that tech what oil i ran or if i even premixed at all. This is someone that has seen hundreds of these engines and honestly if just by looking at it he felt it was worn alot more then most he has seen, im going to take his word.

any dealership could easily open it up and then seal it back up
I'm not knocking the guy, but this thread will likely forever burn in the infamy of opinion taken as fact for all eternity just as others before it have i.e. now you say it's only his opinion, but you started a warning thread implying it as fact

I said "caution" for a reason. I figured its something for those people using MMO to look into and caution. If i wanted to say that MMO ruins engines i would of specified it in the titled and shown proof. Im not trying to prove anything, i wanted to simply bring this incident into the light.

I ran 4oz a tank. Now my engine failed at just about 15k miles on it. The "direct" cause of the failure was an injector not injecting enough fuel do to a small leak and one of my new ignition coils completely shitted out after 12k miles and that combo caused a super lean misfire and POP.

Some people really enjoy lying, makes no real sense but lots of things don't make much sense. He probably stole your engine and hid it in the shed in his backyard. He'll sell it on Ebay pretty soon as a brand new pristine engine with absolutely no wear. Yeah, that's the ticket, he stole your motor, and he's going to put in a race car and probably win the 24 heures du Mans.

spoolin,
do you mind if i ask HOW you premixed?
not sure if it mattered or not, and i personally think idemitsu would be the safe ticket as it comes down to premix...
anywho. do you pump fuel... then pour in the 4oz in the tank?
or do you pour in the X amount, then pump fuel in the tank to mix the blend?
i only ask as i'm surprised about idemitsu getting a bad name, and a cause of clogging fuel filter... MAYBE, just maybe its can be in how the procedure is performed. but who knows?
of course premixing fuel in a separate jug before going into the tank is best bet for evenly distributed lubrication...
just adding in my share on this topic. inputs are welcomed. lets see what methods people use.

I think the logical procedure is to put the pre-mix in before filling the tank up with gas. The flow of the fuel going into the tank will mix the pre-mix in to a certain extent.
I used a bottle of MMO before. I'm not going to lose sleep over it. Many RX7 owners use MMO as premix.

I used MMO. They are not "supposed" to take it apart but they are fellow rotorheads who are curious. And that dealer is amazing, There are like 2 people there that do suck though and i never bother talking to them because one is a bitch and the other will just be rude and try to void your warranty so let me know before you take it in so i can try to direct you to the proper person 
Hey Jeff, I need to go in soon lol, both my headlights and rear tail lights get a little condensation in them... plus if i ever have any problems I want to build up some rep with the good guys...

It will be interesting to see the pics to understand what he's describing as "pristine".
I've been using MMO for about 20,000 miles at about 6 oz per tankful. The only look inside is what I could see through the sparkplug holes, but I assure you there's carbon, at least on the rotor face.

wait i have used it..
and idemitsu, and f+, and redline and lots of other stuff..
i will say now my fuel pump is clean, my motor still has not enough compression. but it was an early build from the old bad rebuild place.
damn you mazda!
the most important thing about premix is mixing before you put it in the tank..
and mazdamainac is correct one one part.. if you just dump and fill it will just collect all the crap in you tank and stick it to the fuel sock..
hey.. but what do i know..
beers

i poured in the premix before filling up the tank. Im not trying to give Idemitsu a bad name at all, the tech just felt like it may of been the cause of his fuel filter getting clogged. Brandon pm me with what year and how many miles are on your new 8 and if its under warranty ill let you know who to talk to.

^Seems to me the lesson in all this fuel sock business is to check yours after you have been premixing for a while. Or, clean it before starting to premix, and then check it after 10 tankfuls or something. I could certainly see different cars having different amounts of crud in the gas tank, depending on where you live and who's fuel you buy. Dirty tank + dump & fill on an empty tank could result in crud in the sock.
Don't know that's true but it could explain why some people have problems and some do not.
Right now I do a pre-pre-mix & intentionally refill when I reach 1/4 tank. Not sure I need to do that but it's what I've adopted. I should check the sock & see what it looks like. It has been 48k after all.

thanks for sharing this dude. Its interesting.
I dont understand the tech responding in that way after he broke the engine down.
Why would he suspect pre mix when a engine is too clean? Premix affect is only going to be at the seals, rotor faces and housings right?
Soooooo-----carbon or no carbon or is it just the right amount of carbon?
Brain strain--will explode.
Think i will just go out and just drive the hell out of it.
Does a 15K engine have THAT much carbon anyway?
I wpnder how the exhaust ports looked?

I think? So I'm guessing that the tech guessed the lack of carbon was related to the lack of lubrication - i.e. some carbon cleaning fluid that affected the engine oil. I dunno if the association is accurate, but that's my interpretation of what was stated.
