MMO... Marvel Mystery Oil

I used one quart of MMO with four quarts of 10w-30 in the last oil change and I'm approaching the 3k mile mark to change again. The color looks fresher after 3k than just running all pennzoil or shell rotella like I've had in the past. I figure the lubricity held up as well so I'm more interested in using this product. I know some engine builders swear by it so I'm wondering how many of you have used it.

I have been using it for many years in all of my vehichles.

In summer months I usually only go 1/2 quart and in winter I go for the full quart.

It is good for keeping the gunk out of the returns,good for cold starts.

I just started using Mobil 1 in my 04 Crew and have not decided on if I would add MMO

Have also used it for storing and or unsiezing motors this stuff is great !!

I had used it in my S-10. It keeps a "problem" lifter from sticking.

I'll mix an oz of it in the lawnmower gas.. Keeps that clean too.

I use some MMM mixed with fuel in my '85 JD 318 garden tractor. I've read on the tractor forums that it helps with top end lubrication.

My dad used to swear by the stuff for unsticking lifters in his Buick Wildcat.

The Facts About Aftermarket Oil Additives

What about Oil Additives like Slick 50, Prolong, Zmax and others

The fact is they are totally useless and in many cases actually detrimental to your engine. The Federal Trade Commission has issued charges of false and deceptive advertising that these and many other additive manufacturers have misled consumers into believing that their products offer increased engine protection and performance when added to your motor oil.

Federal Trade Commission Charges zMax with False and Deceptive Advertising

Read about the latest FTC charges against zMax in our informative articles link. ZMax is the latest company to be charged in a long list of companies. The FTC has successfully halted false and deceptive advertising by the marketers of Dura Lube, Motor Up, Prolong, Valvoline, Slick 50. STP and other major brands of engine treatment systems.

Without going into extensive detail here's what you need to know about aftermarket oil additives: There are basically two types of additives used, either Teflon based with PTFE (like Slick 50) or Chlorinated based (like Dura Lube) with some type of carrier, usually a paraffin based carrier or other mineral oil. Some have extremely large amounts of moly, zinc or phosphorus, all extreme pressure agents which are detrimental to a motor oils proper function in the amount that they use.

Teflon does absolutely nothing inside your engine. Teflon must be heated up to about 800 deg. F to get it to stick to anything for friction reducing purposes, just like the Teflon on a frying pan, yet in your engine all those suspended microscopic colloidal Teflon particles do is gradually attach to you oil pick-up screen and reduce oil flow to your critical components as well as reducing the oil flow in other critical internal engine passages by attaching themselves to the passageway walls. In addition, as your oil filter filters out some of these suspended Teflon particles, your filter flow rate will be reduced which may eventually become restricted and default in to by-pass mode, which means unfiltered oil will be flowing through your engine.

Ever get bleach on your fingers? It's pretty slippery isn't it? Same principle here. Add enough Chlorinated components to a carrier and mix it with some type of teflon, moly, zinc or phosporus & you can reduce the friction, except for one "minor" thing: Chlorinated additives mixed with oil and subjected to heat forms hydrochloric acid! Hydrochloric acid is extremely detrimental to you internal engine parts. Get the picture? That's it in a nutshell. Bottom line is: When using a properly formulated motor oil you do not need any additives whatsoever and additionally, the additives you may put in can react negatively with the additives the oil company carefully blended in. Do yourself a favor and stay away from aftermarket oil additives, regardless of how appealing the bogus claims they make in their advertising are!

What if They Have a Test To Show How Their Additive Works?... Read On............

At a recent trade show we were at one of these miracle oil additive companies was there with a machine that demonstrated how their additive reduced friction. It was a motor with rotating solid steel disc secured to the motor shaft and a torque meter with a flat piece of steel mounted on the torque arm. They put every type of oil on the market, one by one, on the machine & pressed hard on the torque meter and at about 20-40 lb-ft torque the torque arm would stall the motor....that is until they cleaned it off & tried their (chlorinated) additive "IXL" on the bearing & ran the test.

People were amazed as the meter peaked out at 140 lb-ft. torque and still didn't stall the motor! We knew what was happening but many unsuspecting consumers were eating it up and standing in line to buy the additive! The next day we showed up with some Head & Shoulders Shampoo disguised in an oil bottle & had the IXL additive people try it on their test machine. The operator was amazed as the motor just barely stalled at 140 lb-ft! The operator says that's pretty good stuff, what is it? We said Head & Shoulders. He was quite embarrassed to say the least. Head & Shoulders has high levels of high potency ZINC in it that attaches itself to ferrous metals. Coke soft drink will do exactly the same thing. ZINC reduces friction and provides anti-wear protection and is present in most motor oils at a much reduced level. Now, would you put Head & Shoulders in your engine?

Additionally, the test machine was measuring EXTREME PRESSURE. Motor oils do not have extreme pressure additives blended in like gear lubes do. Their is absolutely no need for EP additives in a motor oil. A gear lube would not stall the motor as easily because gear lubes have high levels of Extreme Pressure additives blended in, but do you think they would test their IXL additive against gear lubes? Heck no! They use motor oil....They are comparing apples to oranges & tricking you into buying their additive! Same theory holds true for Slick50, Prolong, Dura Lube, Motor Up, Valvoline Engine Treatment and many others. Please DON'T be fooled by oil additives!

Thanks Goose. I never believed in DuraLube anyways

i found this comment in regards to MMO's use in fuel on www.turbodieselregister.com

"I think it's called mystery oil because no one knows what's in it and the company won't say. The stuff has been around for a long time and was very popular with military aircraft in the late '40s, you would see 55 Ga. drums of it at most airfields. I've heard it's use was banned in aircraft just because they wouldn't say what's in it. The way it works, MMO goes through the fuel system as a droplet, broken up like the fuel. When it enters the combustion chamber and ignites, it is vaporized and soaks into the carbon buildup on combustion chamber walls, valve guides and around the valve stem. It soaks into the carbon and eventually loosens it up and it goes out the exhaust system. It is highly detergent and is more of a solvent than a lubricant. Anything it contacts becomes extremely clean, works great as a parts cleaner. It can play he!l with an older rig that has never used it by loosening more deposits than the engine can eliminate and uncovering deposit sealed leaks. It definitely doesn't have the lubricity or anti-gel properties of a made for diesel fuel treatment.

I will neither recommend or not recommend MMO. I do know it will help when lifters start to be lazy and not do their job. When valves are beginning to stick, it will free them up. Some people swear by it, some people swear at it."

I used to use it in everything.

Now I'm a big Lucas fan. I still use the MMO in old motors that have been sitting and things like that. I mix it with penatration oil for rusty hinges and "whatever".

I use the Lucas in everything I own (cycles to trucks) and will swear by it.

Amen,

My dad swears by it. He has used it for as long as I can remember and he has been a mechanic for 50 years. He started using it when he was a chevrolet mechanic at the dealers. He said they would use it to free up the sludge in engines. I have seen what it does, sludged engine when you pull a valve cover, run one quart in the oil change for 1K miles then the top and bottom end are clean. He does not run it in every oil change, but mainly uses it for cleaning out motors and preventative maintenance.

I have used it before for sticky lifters and it does work.

I would not lump this in the same group as the SLICK Willie 50s. Look at this as more of a Sea Foam, or "Top Engine Cleaner" we use to use at dealers.
