ejlain Posted January 29, 2004 Share Posted January 29, 2004 Hi, I've been hearing and reading a lot about this stuff lately. Anyone ever tried it? I was thinking of using it in my 1998 Legacy L sedan (automatic) w/ 101k miles. I'm due for an oil change soon, so I was thinking of using the stuff, letting it clean up what it can (and see if it solves my lifter clicking) and then getting a fresh oil change. I picked up a 16 oz. bottle at Pep Boys. Do I pour it right into the oil fill tube? How much should I use? Can I add to the gas thru the gas tank? Any input is appreciated. Thanks.

99obw Posted January 29, 2004 Share Posted January 29, 2004 I have been using it as an after-run oil for model airplane engines for about twenty years. Works great as an air tool oil. I would not add it to a car's oil or fuel. If you want to clean your engine use an internal engine cleaner such as AutoRX. If you want to clean your fuel system try Techron.

Makes the RX run like it's on fire and I've had many friends who have solved lifter noise problems by running it in the oil. The legacy loves Techron, but that darn stuff is expensive! I've just recently used the marvel in the legacy and it seems to be running better. Quote Link to comment Share on other sites More sharing options...
99obw Posted January 29, 2004 Share Posted January 29, 2004 Simply because I think better products are available. I think using it as an internal engine cleaner may not be the best, as it works rather quickly and can dislodge chunks of debris, potentially causing more harm than good. It will thin the oil, possibly out of grade. Many engine cleaners that use similar ingredients advise not to drive the car with the additive in the oil. It may be ok as a fuel additive, but I find it's use unnecessary. Interesting thread... Quote Link to comment Share on other sites More sharing options...
PAezb Posted January 30, 2004 Share Posted January 30, 2004 I've tried MMO once and didn't like it at all. I use nothing but SeaFoam Motor Tuneup in the Gas, Oil, and Throttle Body. I use SeaFoam on all my small engine Equipment as well (Lawn Tractor, Snow Thrower, Wood Chipper, etc). Can't speak highly enough about it...

TheSubaruJunkie Posted January 30, 2004 Share Posted January 30, 2004 Seafoam is great for gas and throttle body, but I live by MMO. Nothing makes my car run better than choking it to death a few times with MMO. Maybe because my car is 20 years old, and carburated. I usually run with 1qt in the crank, but since the car leaks so much oil, it probably doesnt stay in for long. If you want to use it, just add 1qt to your crank after an oil change. Then just top the oil off with regular 10/30 or 20/50, whichever you use. If you are going to use it in the gas, just add it to the tank as specified. I usually put a quart in with a 10gal fill up every other month or so. Seafoam seems alittle more harsh on the engine than a good shot of MMO. -Brian Quote Link to comment Share on other sites More sharing options...
CROSSTBOLT Posted January 30, 2004 Share Posted January 30, 2004 MMO is nothing more than an expensive equivalent to ATF or Mil 5606 (Aircraft hydraulic oil). MMO has been around a long time. It has many followers that say it solves all kinds of problems. I do not doubt that it has some effect on hydraulic lifters that are a bit sticky.

My car seemed to run rough with the MMO treatment, especially when added to the crank. I add a third to half a can of SeaFoam to the crank every other, to every third oil change, 500 or so miles before I dump the oil, and have had great results. Also, sucking up a can into the throttle through one of the vacuum hoses, twice a year, really smooths out the idling. Just to add, I have a friend who has had his single engine pilot license and has owned his own plane for many years. He was the one the recommended MMO to me, as he and his mechanic are both proponents of it, and use treatments regularily on his aircraft's engine, a Cessna 152. I guess it's just how each of our experiences go... Paul Quote Link to comment Share on other sites More sharing options...
NOMAD327 Posted January 30, 2004 Share Posted January 30, 2004 I have had a number of Chrysler products with the 3.0 Mitsubishi V6 engine. That engine has extremely tiny hydraulic lifters that love to block and the engine is notorious for cold tappet noise as a result. All those engines were completely cured by adding one pint (to 4 qt. oil) of Marvel Mystery Oil or CD-2 top end lube to each oil change. It was necessary to do it once with each oil change, on those motors at least, you could not get ahead of the problem and go back to regular oil without the noise returning.
