Marvel Mystery Oil what does it do for your engine and fuel system? Who here uses it and have you noticed any benifits?

Thanks
Joe

It smells nice, I use it in my air tools but not in an engine. Supposed to be a "top end cylinder lube" whatever that is. I'll read the can again tommorw and see what they claim benefits are.

it does a good job of cleaning out fuel injectors when dumped in the gas tank every few thousand miles.

MM Oil cleaned up a stuck lifter, even after changing the engine oil 1000 miles for three times.

Also, quiets screen door hinges.

I figure it is a high grade ester based lube but really have not looked deep enough to know for sure.

Esters are good cleaners and very good lubes.

MMO can clean combustion chamber deposits b/c if I have this right it decomposes at temperature and kinda "acts like it "steam-cleans" the chambers walls and valves and such after a while of use..

I've used the stuff off and on for years and years after I couldn't get my old '52 Willis Aero Eagle H/T, 6-banger started b/c of some dry and stuck rings back about 1968 or so!

The old, "white-headed" Mechanic across the street told me to squirt some MMO in each cylinder and let her set for a while, then crank her over... I did AND she took off like a champ!!

He said the stuff was a great "top-oil" AND I believed him on that after he told me what a "top-oil" was...

I add a half a small bottle to my oil at change and the rest in my tank about every 3rd oil change or so.. And when I was still driving my Metro, 3-banger corn-popper I gave my son, I could physically feel the diff. it made commuting..

Good old stuff!! I haven't used "Bardahl", but I figure it is about the same since it is another old top-oil that's been around for years and years...

According to the info on the can I have at work this stuff will cure everthing but herpes. :eek: Like I posted earlier, I have never used it in an engine personally, but others seem to swear by it so by all means give it a try and let us know how it works.
The top cylinder lube claims that it will not burn off or break down and coats the cyl. and valves to prevent corrosion, might be good for storing an engine.

I used to know a guy who always used it in his three first generation camaro's for years. He swore by it.

Right or wrong I use a half a bottle in each tank and add a little in each oil change on my 68 rebuilt 327, has 86,000 origianl miles and about 200 since rebuild. I suspect it will help with the winter storage, along with the stabil I added this week.
PS I also add some octane boost and some lead additive with the MMO.
I might be nuts, but love our old 68.

How many ounces are in the bottles are all of you using or talking about? I have only seen it for sale in 1 gallon cans in my area.

I have some noisey lifters and was thinking of trying the stuff out. How much ( oz ) should I add?

Thanks
Joe

I can see using the stuff to try and fix a problem without disassembly, but to pour oil in the gas tank on a regular basis ??? Since when did GM make a two stroke V-8 Camaro :rolleyes: It goes against the grain of everything we know about engines. You do not want oil getting in the combustion chamber. It is known to lower the octane of fuel, etc etc etc. Same thing goes with putting it in your oil ... the chemists spend millions trying to come up with an oil formulation that will protect our engines, and what are we going to do ... second guess them and add something else ??
I have never used any type of oil or fuel additive since I started driving in 1966 and dont see any need to start now.
Just my opinion,

Bill,

I don't think MMO is really high grade oil at all, even though it might be called "petroleum based".. And what I am calling oil are mixtures of straight "alkane chains" is all...

Like I said, I haven't dug deep enough so I will try to find out just what the chemical name of the stuff is so we will know for sure..

pdq67

Bill;
I hear what your saying, it all seems to be snake oil to me also. This just happens to be one that I have heard about for many years. Unlike slick 50 or the other products like it this one seems to have some staying power on the market.

I will have to admit, I filled a crank case of a 79 Trans Am with STP and traded it in to hide a rod knock many years ago. It worked but not for long, got a call the next day from the dealer telling the salesman that drove it home blew a rod out of it and wanted to know if I was intrested in buying the car back, as it was cheaper to almost give it back to me than to fix it or take to the auction. Went and picked it up the next day for $100.00.

That's my only experiance with additives, and it's not a good one.

Anyone know how quickly to change your oil after adding this stuff to try to clean out some dirty lifters?

Joe

Joe, I used the pint size bottle and added it to the existing 5 qts of oil in the crankcase. It took about 300 miles to clean up the stuck lifter.

Now, as I stated, I previously changed the oil 3X every 1K miles just before adding. Whether or not it worked, may be coincidence, but, the engine, 68 Camaro 327 4-bbl, did run alot better during and after the addition.

Two years ago, I had a 90 300ZX N/A, 168K miles, I bought at a body shop auction. Had (a) stuck lifter(s), DOHC, 4 valves/cylinder. Poured in a quart to existing oil, already full on dipstick. Within 50 miles, the lifter(s) loosen and the engine smoothed right out.

With both engines, kept the mixture in till the next scheduled oil change at 3K miles. I haven't tried it in the tank. I'm a believer if the engine uses a quart of oil between scheduled oil changes, the top end is getting lubed. Why would I want to add it to the tank?......Hmmm, I do have a test bed-Buford......

Does work well for door hinges, typewriters, sewing machines, diesel engines needing kerosene to cold start........

I just found this if it is still accirate?

MMO's MSDS sheet...

http://msds.pdc.cornell.edu/msds/msdsdod/a214/m106642.htm

I love it that all the "mumbo gumbo" names used in it still do not say what each portion chemically is.

One thing I do know is that Biodiesel has esters in it and is one of the best lubricity products there is.. Stuff is slick like a drop of "ROIL" on a ball-bearing friction test machine!!!

I haven't made it over to UMC's School of Ag. to talk to the Prof. that is big-time into Biodiesel yet b/c I want to know which ester fraction in it is the one with the most lubricity since it naturally contains like 5 to 7 different esters.

I first learned about MMO on a Goldwing forum I belong to. I have now put in a few ounces in my gas tank (5 gal tank) at each fill and although it's got a name that sounds suspect, it absolutely cleaned up the top end of the bike and made it run and idle better.

Also, I belong to another bike forum (hey I have bikes and Camaros) and in that one, someone wondered if it would help for winterizing and - apparently not. It's not an additive for the winter, just for cleaning the carb(s) out good and the valves, etc.

I have never used it excpet for around the garage. I do use an Amsoil additive (Performance Inhancer) to my gas, and I can tell you it keeps the valves and pistons clean. I really noticed a difference after using it for a while. I used it all the time in my Camaro and from time to time in my other vehicles. The stuff works. If MM oil is doing the same job, that would sure be a lot cheaper.

What do you all mean by "top end"? Does this stuff just clean the top end of the motor?

Domano,

You need to pick up a bottle of MMO at a Parts Store or local Walmarts and just take about five minutes to read what they say a "top-oil" is. That way you will have a run down on the straight skinny of the atributes they hope to sell it to do..

But to me, a "top-oil" is a high grade, thin weight, "oil-type", solvent that when added to your oil and gas tank, gets into the ring stack areas, up into the valve guide and seal areas.

And helps clean everything from the intake tract and combustion chamber as well as the backs of the valves and the insides of the motor itself between oil changes.

To me, good old, "snake-oil" named MMO has worked very good for what I think it actually does which is help keep my motor clean and running just a very small schosh better!!

AND again, to me it's well worth the use every three or so oil changes.. 1/2 a small bottle in my oil at change and the rest in my tank at fill-up..

I know I don't have to use it but I honestly have felt my old '87 Chevy Sprint ER and '00 Chevy Metro, 1000 cc, 3-banger, corn-popper cars run better commuting daily after it was added at an oil change..

BUT as BillK say's.. And I very much respect Bill's opinion....

I've used two lube additives in my long driving time, MMO and good old STP, or "Motor Honey" type stuff when my old motor was really loose!!!

And figure I got what I paid for..

pdq67

PS., when you only have 48hp or 58 hp, you tend ta notice small changes in performance commuting daily like anywhere from 60 to 180 miles a day... That's what I'm going by..

Well my Uncle had a stuck oil ring in a pro street 66 Nova with a Blown (671 Blower) small block. He added MMO because the local engine guru said try it before you tear the motor apart, and it worked! Now he adds it to all his cars. So I think this snake oil works. Sincerely Steve

I have customers that swear by the stuff for winterizing their marine engines, instead of using an over the counter fogging oil. A commercial tugboat line in Boston I know of uses a gallon in the fuel of every fill up.
Myself, I don't use it, I trust Amsoil's additives that are in their oil already. In fact, I just went to their straight 60 in my old panhead harley, and noticed a night and day difference in noise and even ease of starting.. (still shaking my head on that one)If I had a problem (stuck ring or funky lifter etc..) I'd give it a try though..

One of my sons has an older Saturn that was using oil. I did research on one of the Saturn forums, & there was a thread about using MMO to free stuck piston rings and get oil consumption back under control. Figured we didn't have anything to loose so we pulled the plugs, poured in some MMO & let it sit overnight. Next morning cranked the engine over several times with the plugs still out to clear the cylinders, put them back in, started it up, fogged out our neighbors for about 2 minutes but it worked. Cut way down on his oil consumption! I'm a believer because it worked for him but have not felt the need to try it in any of my cars yet.

60wt, that's a new one on me??

I'd probably just add (4) quarts of 90wt gear lube a quart of say 10wt in my car if I ever let one get THAT loose!!

pdq67

Good to see all the responces about this MMO. I call it snake oil because I have heard of it's magical curing abilities for years for many things. I think I will give it a try and see what happens.

What I need to know from those using it:
How many ounces are you putting into a Camaro tank full?
How Many ounces are you adding to oil at oil change or at any givin time?

Thanks
Joe

Sure, now this is in my 3-banger corn-popper commuter cars and my Accent.

Half a small bottle in both the oil at change AND I don't worry about over-filling and the other half in my tank at fill-up which is like 10 or so gallons..

Like every third or forth oil change sorta deal.. But I tend ta run my oil like a looonnnggg time sometimes, b/c of my highway daily commuting almost 95+ percent of the time...

Upwards ta 11,000+ miles between changes and on good old Walmart Tech2000 stuff to boot... Used the Tech2000 oil and filters for more years then I wanna remember b/c it just reminds me that I'm now an old-fart!!!

I know, I know, I'm a tight-a--, er, eh, -- "frugal"!!!

pdq67

I put in about 10 oz in my crankcase. I think it calls for one entire quart for the crankcase. I have been monitoring the oil and it is dirtier each time. Guess its doing something.

put 20 oz in the with the oil and after 20 miles lifters are quite as a church mouse. Don't know how long it will last but I think I will be adding it oil changes. Put the othe 12 oz from the bottle I bought in the gas tank. Who knows what will happen here, only time will tell.

Joe

Never mind ;)

Well Time has told, that 20 Oz in the gas was the wrong thing to do. Detonation and ping is what I have now. I will continue use it in my oil as it really seems to work there for my need. My lifters have been noisy for years and I have changed oil in it many times trying to clean them out, made adj to the lash a thousand times. I was at the point of changing them out soon.

No more MMO in the gas tank for me though!

Joe

Thanks for the report. The MMO may be removing the carbon thus making for a hotter chamber, just a theory.

Glad the lifters quieted down. Change oil soon.
