    Over the last two years and 9,500 miles I have added about 6 oz of synthetic 2 cycl oil to every tank. And lots of various carbon cleaners, often Techron. In that period of time the engine progressed from good-enough to spectacular. But I have often wondered about MMO. Its what the mechanic I bought the car from said he used.

    So today I added a full 16 ounces of the stuff. Never ran better. Like a humming bird deranged at 7,000 rpms. And will lug up my little mountain at 1,100 rpm in third without a hickup. Sixteen ounces seems a little much. But the car tells me otherwise.

    That's why they sound so good.

    I love the smell of scooters......
    ...it's one of my favourite toxic smells ;-)

    Would someone speculate on what it might do? It certainly does not solubilize the stone-like crud I find in my throttle body around the idle screw; nothing but a wire wheel will take it off. Does it lubricate the injectors? Or the fuel pumps? Is it perhaps psychological; it really doesn't do anything but because you put it in the gas tank you are expecting it to do something good? In any case. I also like it but have not run it in my Mondial T as yet but I might start doing so.

    Well, as the name implies... it's a mystery. ;)

    However, as per the company, adding MMO to your gas, engine oil etc. doesn't hurt anything.

    ::Marvel Mystery Oil::

    Probably no different than other injector cleaning, sludge-busting additives.

    Ferrari was evidently working with Evinrude.

    If you have cats, would it tend to clog them up?

    Only if your motor is blowing oil and/or is running too rich. But then, you'd have the same cat problems even without using MMO.

    There is a lot of study and research touting the benefits of (tc-w3 type only) two cycle oil in gasoline at about a 1oz to 5 gallon ratio. Search the Internet and decide for yourselves rather than just dismissing out of hand

    I would be hesitant to put that in my oil, unless I planned to do an oil change within a few miles. I can't see how it doesn't dilute the oil.

    As a fuel additive, no problem. You can also read up on toluene, about 1:10 ratio. Works best for FI cars as an octane booster but may not be very compatible with older rubber hoses.

    Regards,
    Jerry

    I use to use it all the time twenty years ago when I owned my shop near BG Products in Charlotte, North Carolina USA.

    Sold quite a bit of it to folks with cruddy K-Jetronic systems (mostly VW/Audi and a few 308/328/Mondial/TR's). It worked extremely well for BMW 320i's that were prone to "buildup" on the back of the intake valves that badly affected idle quality and off throttle drivability.

    It was a good "topical" fix and idle quality was improved. Never saw any downside but began to remove injectors and use my Bosch Tester to clean and verify patterns. I think it's one of the few additives that works and it sounds ideal for a high-mileage 308/328.

    I don't think anyone here is dismissing anything. We are simply discussing and asking questions.
    Isn't that what Fchat is all about?

    If it works for you without detrimental side effects, Bravo!

    Any burnable substance will have residue. The question is: will that residue clog anything up.
    I don't have cats so it would be a non issue for me.
    Also, I don't have any drivability issues with my car so I would pass on this, for now.

    What about rubber parts, will it have any bad effect on rubber?
    I know that Chevron Techron is a great injector cleaner but it has a negative effect on rubber, so for now, it is off my list.
    Lucas injector cleaner and lubricant works well for me. I use it on my first fill up of the season and the last fill up of the season, just before storage.

    My 2 cents.

    Interesting. I had never heard of rubber issues with Techron, which is also a stand alone injection cleaner, along with being added to all Chevron gasoline. I use Chevron most of the time, including the Mondi.

    Any experience with Ventil Sauber?

    David J.

    I also use Lucas products. And I also worry about old rubber hoses. I had a long discussion with a guy who owns an oder Fiat 124 Spyder from about 1976 or such that used Bosch fuel injection. He said one Spring his fuel distribution system was all clogged up with dust like hose decomposition.

    When I get a chance I intend to inspect these hoses but as of right now I don't even know where are the potential culprits. They may have been replace by previous owners and I will search the receipts.

    The Marvel Mystery Oil site states you can use up to 25% in oil. I believe it is something like kerosene well doctored up with solvents. Moslty I suspect it is good in oil for sticky hydraulic lifters. We don't have those, and I doubt many of us have sticky piston rings. However, perhaps next time I change oil I might try some for a short period of time.

    But probably not since the car runs as good or better then any other car I have owned. The engine is a piece of magic since has max hp at about 7,000 rpm but can lug along perfectly content in 3rd gear at 1,100 rpm up my little mountain.

    This should be impossible.

    My car takes 10 or 11 quarts of oil. No way would I put in 2 or 3 quarts of this stuff.

    I know MMO has been around a long time, but oil has very different properties than MMO and I want that 50 weight I added to protect me when I am revving the motor as it is meant to be revved.

    As I say, for a short time to coat things and then change out the oil, OK, or adding a few oz.'s to the fuel can't do much harm.

    Regards,
    Jerry

    I have never added MMO to my oil and don't plan to either. Its just what their site says is ok. Kind of extreme imho ....
