if the oil and MMO is changed, at 200 to 300, to fresh oil ...it appears to do no damage .. and brings out an amazing amount of Gunge... but you should NOT do this unless you have a cleaning reason ....

It is a thinner "oil" , and the recommendations are not to run it very hard during those 200 mil.... ...However, in the gas on a frequent basis... does keep those carbs clean.... so you can add it as you wish... and MMO is really just ATF fluid... so if $$$ is a problem... just buy some of that...

Are you sh---ing me? Is that what MMO really is. I do have valve clatter and I am coming up to an oil change, so now may be a good time to dump a litre and add a litre of MMO/ ATF to the old fart. Man, I would sure like to have some concensus on that one. Not that I don't trust you SilverDave--I do.

How muchATF to a tank of gas, and how often. I have not seen MMO in any local store- or for that matter Seafoam either. This would be a revelation for me.

Thanks Ken

Firstly .. In your province , Canadian Tire SHOULD carry MMO... if not , head over to Maine ... and Users of Tractors, Bikes, and cars have used it in gas (2 glugs) and in oil (sparingly .. drain after 200 miles ) for years... I am not a chemist... no .. scratch that .. I was a chemist in the 60's... but I have never recently analyzed MMO.... but I have seen that comment for years , on the GWRRA site... that MMO is an additive rich ATF... but that the primary cleaning is from the ATF... Find someone else in your local GWRRA club, and get another opinion... or wait around here, and you will CERTAINLY get at least 4 more opinions ..............................as to the gas... apparently Some of the Carb / injector cleaners , like STP, are very harsh on rubber gaskets in older carb models... MMO is supposed to be a gentler cleaner, and two glugs per motorcycle tank DO help... at least on my lawn mower, bike, and small tractor (all carb driven) they do ..SilverDave/forums/images/emoticons/emoticonsxtra/cooldj.gif It is also well known that MMO acts as a deer alert, and repels Bunnies, if they have pancakes on their heads.... and there's the real point... should you take ANY advice from a site that has 11,000 views,and 1200 posts on deer alerts ?? Others must think we are all bonkers !!!

I found MMO at two CTC stores today. Even after two long time employees told me they had never heard of it. Marvel Mystery Oil--in a bright red bottle whose contents are 946 ml. Gee, that must be a US quart:baffled:

Gonna give it a try.

Twisty, you are simple taking the mystique out of that stuff. How then do you explain how several people have drained out black gunky stuff after using the MMO, whereas previously, without the MMO, the oil drained out fairly clean?

So you are saying that the dark sludge coming out after an MMO flush could be the MMO itself. Man, does the plot thicken. I just read the label on the bottle of MMO and it claims to do a whole bunch of good things to the inners of an engine when added to the oil. If it breaks down like you suggest, would the makers of it not have been sued by this time(since 1923) Guess I will put off using it in my engine until I hear some more about it.

If one were to keep very close track of the oil level and noted if it actually lowered during the 250 mile period of the flush, then your "liquid evaporation or burn off" of the MMO could easily be verified.

Hawker, lets look at this form another angle.. If an engine is sludged up inside there is just no way a modern detergent oil will go 2000-3000 miles & come out of that engineclean. SO, if the previous oil changes are dropping clean oil & adding MMO allows it to drop out black & gummy looking where's the black coming from?

Twisty

Mornin Twisty: I have not yet used MMOand am only trying to understand why some people who have used it, claim that it does in fact, clean the engine where regular detergent oils would not. "Where's the black coming from" Could it be possible that the MMO will clean a bit better than the detergent oil and would therefore take off sludge and varnish that the regular oil missed, causing the drain to come out dirtier than the regular oil drain?

I am not trying to be argumentative, I am simply trying to get to the answer. How about we get some past users of MMO to chime in. If it proves to be no better than regular oil for cleaning, then I will not use it for that purpose. But as usual, it will be a subjective issue. Some do, some don't
