OK, went on a long road trip this weekend to visit my brother. Decided to try a little experiment. Car is a stock 186k (187k now!) 12A powered 85 GSL 5 speed. So-so cap and rotor, new plugs, wires, and fluid change. Stock exhaust except for muffler. Tires are stock size Michelins at 36 psi. All gas used was Chevron 87 octane from high-traffic stations.

Previous mileage before oil and synthetics in tranny and diff, 70% hwy, 30% city: 20.5 MPG.

Mileage experienced with fluid change, 90% hwy, 10% city: 25.5 mpg

Same as above but with 8 oz of MMO added to a full tank: 24.7 mpg!

Next tank, NO MMO, mileage went back up to 25.4 MPG!!

My results show a LOSS in mileage with MMO. I tried to make the experiment as exact as possible (cruise control, same roads, etc), and I DO believe the results. Just thought I'd share, since I was extremely suprised, and disappointed, with the results. Seeing as how this motor (and many others) has lasted quite stongly this entire time running w/o additives in the gas, I also do not believe the MMO added in the tank will pay for itself with increased motor protection.

My next experiment (later this week) is to check compression of this million mile motor before/after a full MMO treatment to see if it can live up to it's hype in that situation. The second use of this experiment will to see if I get kicked out of my apartment complex after starting the car back up full of MMO!

Haha,

If you get kicked out, write a letter to MMO, and complain, that not only did their product harm your performance, it evicted you and your car.

Make them pay, or you will go as public as possible with the results.....LOL

Eh, lease is up in less than a month, so I could care less - I've been waiting for awhile to do it anyway, and now that I have a daily driver, I can let this car soak for a couple days...


Oh, and pics are sure to come. I think I killed a few neighbor kittens when I had to use MMO to unflood my roommates 88 'Vert, but that was nothing compared to the "full treatment" that I expect...

I am on the third tank since I puirchased my seven. The first tank has some MMO on it (even before I checked out this site-(I already had some), and the last tank has 1/3 quart in it. I have noticed with the last tank that my rex runs muich better (more power). Is it the MMO? I don't know. Is the MMO similar to 2stroke premix oil?

Look, I don't think anyone said it would improve your gas mileage or make your motor last longer. All it does is cleans **** out of the carb and engine. That's worth a mile/per gallon to me. Actually, my car wouldn't run at all until I put MMO in the tank. What do you say to that? I have also used it in old Hondas, and, after a few oil changes, oil consumption drops drammatically. MMO is a cleaner. It's a marvel and a mystery, not a miracle.

Wait....everyone put snake oil in your car and
it will cure all ailments and save you money.

BRealistic

Where can I get snake oil? Is it environment friendly- don't want PETA throwing tofu rotors at my car when I pass becuase snakes were harmed to get my snake oil

Cody

Can we just put in snakes?

Sterling

Yeah- MMO cured my Mamas cancer! It cures diaper rash, too.
N' uncle jake says his skin lesions have done gone away. He just dribbles a teaspoon on his Grape Nuts ever' mornin'.

Jesus Christ, people! ****** research how it works! You guys are'nt noticing anyfriggin thing that has'nt been happening all along. You're simply being extra vigilant to see if this works, and thus stumbling upon the fact that fuel consumption or engine power are things that do in fact fluxuate with humidity, temerature, where you fueled up (I think we'd all cringe if we knew the details of how fuel varies from station to station!) how much luggage you had in the car- all kinds of ****! It's a carbureted engine! That leaves it even more vulnerable to these elements.

But instead you chalk it up to tossing more oil through your engines! Christ, people!- It's not a damn two stroke, Ok?- It's a rotary!

Just coat the damn rotors with the ****- using as little as possible to do that, and let it sit for FORTY EIGHT hours, folks! That's right- Don't touch her!- I know it's hard, but just leave 'er be.

Then you get it started and run the **** outta her. And I mean RUN THE **** OUTTA HER! But DON'T over heat it!

That's the best you can do.

People used to dribble water down their carbed piston engines to try to clean out deposits. That was a gamble, I guess. I've only read about it.

If you're gonna run oil through her via the fuel tank, run two stroke, and disconnect the OMP.

Yooooooo-Hoooo!!!! The racecar drivers have a bit more experience than all you guys. Do what they've been doing for years and years.
Wake up.

MMO Hater!!!

Unflooding engines and/or removing carbon build up - yes

Additive to fuel? I don't use it that way, and I agree with sterling. If you want to put oil in your gas, use 2 stroke oil and disable the omp.

BRealistic

Why is it bad to put MMO in the gas? Isn't that even more protection in combination with the OMP? And if coating the rotors helps, why wouldn't running MMO throught the system constantly?

I will not speak to the results since I have just started trying it, however. A single tankfull is NOT an adequate test. There are too many variables. I would check figures for a period of couple thousand miles, filling at the same PUMP, during a non-season changing period, with the same overall type of driving.

Your heart is in the right place however by trying to make a judgement based on 1st hand experience. Perhaps others will try that and see what they get. I unfortunately do not have a 7 on the street at this moment, but the next restoration should be done in a few weeks. However, I cannot make a good judgement because of "other factors" like frequent autocrossing. I did have a customer try it recently (on recomendations from this list). He has very repeatable driving habits but is not one to keep track of milage. He did report immeadiately that the engine did run smoother.,?.,?

I do highly recomend synthetics and yes I DO put it in the engine as well (Amsoil). I just had a Miata customer call me and say that the synthetic I put in his transmission 2 weeks ago made a huge difference in shifting, particularly into 1st.

Sterling

Uhhmmm- Sorrow- did you read my post twice so that you could find this gigantic descrepency, or was it so absolutely glaringly obvious to you that you could'nt help yourself?
Sure looks great when you take it out of context, huh?
Kudos to you, Sorrow, for pickin' up on that.
Moron.
I suppose that the thin little line in a piston four cycle engine where fuel mixture just barely touches the crank case oil at the other side on the rings makes it a two stroke, right?

You people do not have any respect for dulling out poor information. You do not care about ensuring that the information is well thought out before it's delivery, or that it's presented so vaguely, that newbes that read it may actually believe what you're saying! And so without adding any details, such as how much you're actually using, it makes no never mind to you if they leave this thread with the idea that they should glug-glug a quart of this **** down their carb, or stuff some in their tank.

Well, I do actually care about the newbes that bother to search for information. And they'll see this as a much easier performance mod to do than headers...cheaper, too. If they still have their emissions control **** on, or their $1200.00 exhaust with the three cats on it, this **** can really **** THAT UP! They can burn out their cats if they don't do this right!

But hey, Sorrow- At least ya caught my big fuckup, there big guy.

SoRRoW

I thought it was just funny,

I hope it didnt bring down your morality.

Thats good your giving helpful info to others,dont critize them.

I have ran MMO in my engine for a while,I just cracked it open 4 days ago,My Apex,side seals,corner seals,springs and rotor has some minor carbon build up.I personally think it has helped,compared to others I have taken apart,and were trashed.

If I was worried about my gas milage,I would be modding my rotory,or be driving it to save on gas.

OMP + MMO = Overkill

When you put it in, do you spin it befor eyou leave it sit for 48 hours?

ahaha


Why isnt a rotary a 2 cycle? It sure as **** sounds like a weed wacker on crack running open header........

I believe it helps seals do their job as well as remove carbon from ****... I've put it in piston engined cars before and I do notice a little extra low end torque with it... (Desperately needed on all the cars I drive. I guess that's a characteristic of Japaneese Low stroke engines... No torque.) Although I'm not going to remove the head and check the valve seats before and after use... Hey.. maybe it is an illusion... I dunno, never dyno tested... Nor am I ever going to put my Honda on a dyno... It's not m@d JDM y0...

I do agree that several trials need to be done. One tank you could have had a little more time spent at red lights, or following some granny, or something...

Sooner or later, I will find some kinda engine, probaby a lawnmower or something and tear it down before MMO, put it together, add MMO and tear it down again.

your all going to die down here. er, mmo sucks. really, mmo isn't combustable like gas, it just burns clean and is supposed to help in lubricating and ridding of deposits. since it is now taking the place of some of your fuel i'd imagine that maybe your mileage would go down. also as was said, you tested one tank of gas. maybe you ought to use less then 8 oz. maybe just dump in a bottle every once in a while. besides, everyone knows you are supposed to use atf and rubbing alcohol. duh.

Sterling

Now that's what a sig ought to be-
...funny!

Sterling - chill out. I'm not a noob, and I search more than make pointless posts, especially flames. I explained all the details of my "experiment" so that the results could be easily understood. Take them how you will.

Many people have suggested, and will continue to suggest, that MMO SHOULD be added to the gas of a rotary-powered vehicle. I disagree. I pointed out my first hand experience in an effort to share my own insight. Whether you agree or not, or even decide to flame, I could care less. For me, the forum is about sharing info, not pointless post-whoring and flaming. There are plenty of other places to do that if you are too lazy to go out in the garage and turn wrenches.

As for dribbling water down the carb, if you understood motors, you would understand why it is highly effective. Try actually TRYING something and comparing before/after if you want to see if it works.

Also, read the MMO label - it clearly explains that it can be used as a gasoline additive. However, just like other gas additives, I don't think it's worth the extra money in the long run.

Sterling

Cloud-

Firstly, I hope the hell you did'nt just accuse me of being a post-*****! I've been here for two years and have less than 800 posts here.
As far as turning wrenches, you don't know my wrench turning experience, so don't go there, ok? I'm not the most experienced, that's for sure, but I'm sure as hell not "lazy"!
And finally, as for the water injection benifits- I know all about it from research I've done for hours and hours for my Eaton blower project. Don't tell me I don't know how a motor works in an effort to make me look like some ignorant kid shooting his mouth off.

I'm not calling you a "noob" or "newbe". My point regarding was that more explicit, detailed instructions need to be given along side these relatively rotary specific "fix-its", that's all. Now pouring some in the fuel tank may not even be all that rotary specific, but it's the pouring of it down the carb or the soaking that I hardly ever see enough detail about.

The bit about dribbling water down the carb was an example of advice that really yeilded results, but you had to know what the danger was, and that was freed carbon getting crunched and trapped behind the valve seats resulting in lost compression. Too much water could actually lock up an engine if it stalled.
But it did work! It's just that if you did'nt tell someone why it worked or the details of how much water should be used, he could have the thought that "a drbble" is a coffee can per minute, while your idea of a "dribble" is a cup per minute!

That's all my beef is. I already know about the MMO treatment, and it works really great. I can't wait to see the results of water injection- as a learning experience, I may set that up on my stock engine before installing the Eaton and IC just to see what kind of difference it makes.

The details of your experiment are well recieved as such- and I admitt that I "jumped the gun" on this one.

My appologies to you.

But I've been on this kick for a while about not providing a full explaination with such posts that include quantity and procedure. After rereading, I realize that all you were doing was being scientific and posting preliminary data.
Kudos- it's the way it should be done.


Again, my appologies to you. I'm not trying to flame anyone, just set the record straight about this magical detergent oil.
I remember as an 8 yr old my dad having the head off his 67 Healy and using MMO to clean the valves.
Even the square gallon can was so well decorated that it looked like it contained something special! As I bathed my hands in red oil aside my dad with steel wool scouring black sooty stuff that flaked off srange shaped steel parts called "valves", and even though I did'nt quite understand yet what it was these things did, I knew then and there that my future lied with something bigger- Something without "valves".

(O.K.- That last part I made up. I remember thinking I was hot **** cause I knew what a "valve" was! )

Gasoline burns much much better than MMO. You're simply diluting your gasoline with MMO and reducing the gasoline's effectiveness. Plus MMO would lower the octane rating too.

I'd expect worse gas mileage.

When I run Gumout Fuel Injection Cleaner in my Amigo V6 mileage does drop with that tank of gas. After that tank, mileage goes up seeing the fuel system is now cleaner.

Same principle excluding all the other variables that Sterling went over.
