Sea Foam does clean stuff. I've tested it.

Considering my oil was normal looking, then I added it to the crankcase, ran about 50 miles, then drained it, and the oil was black and the innards of the motor was pretty well cleaned up when I pulled the oil pan, yes.

Sorry, but can only allow double-blind, scientific, objective test results.

Last time I bought a bottle of Amsoil P.I. and put it in my gas tank. I think the stuff actually worked because I did get more mileage (about 70-100 km more which was crazy because I had the AC on most of the time and my car was loaded with 4 people). Not sure if it cleaned my fuel system though as the bottle said it would

Just about any comparable light oil mix will do what Seafoam or Marvel does. There's nothing special in there. You can make your own "seafoam" for a lot less money.

Note that the Trans Tune and Motor Treatment use the same ingredients.

As does Deep Creep.

LOL at the snake oil guys. :laugh:

We keep our machinery running top notch. If there is a mechanical problem it gets fixed mechanically. There is no such thing as a mechanic in a bottle! Lot of people may tell you otherwise and of course it depends on what's wrong too. Minor things can be "settled" down with additives. Not because they fix it but because they may help loosen up FOD that is causing the problem in the first place.

Comparing MM to Slick50? That stuff is a joke. Do people actually believe that tiny particles of the slipperiest resin on the good Earth can mysteriously bond to the cylinder walls and help reduce friction? Of course as these are the same folks that think you can wire tie a alnico cow magnet to your fuel line and boost gas mileage!

I don't use MM in the crankcase. Don't think my wet clutches would like that at all. Even moly oils mess with them.

I like MM because it's a great general purpose product. From air tool oilers to a wetting agent to keep tines rust free. I've heard about the similarities with ATF but never tried it.

We don't have a truck with less than 250k on it so I think something good is going on here. Don't get me wrong if you change oil regularly and never let the oil pump run dry you're doing 99% of what's needed to keep an engine healthy. Aside from running it with no water if you're wet on top. I'm a river rat so I can tell you all kinds of stories of large outboards. Boaters tend to be religious even with their oil mixes and I've heard it all.

As far as the manufactures knowing what they are doing you got that right! Now why would they want you to keep a car for DECADES with half a million miles on the clock running strong when today everyone leases every three years and now we have a program where perfectly good engines are getting seized! :|

I'm waiting for the next miracle product that claims to restore an engine that was disabled for the CARS program! :laugh:

While I agree that no additive will fix a broken engine, there are issues that can be helped if plain old oil isn't doing it. I tried MMO in a pickup with a stuck lifter, and it solved the problem. I've also had very good luck cleaning carbon out of an intake manifold with spray solvent, that saved me from having to pull the manifold. As engines age they often develop minor problems that can be mitigated with different oils or solvents. None of them are a magic cure all, but some of them are very useful for specific problems.


The only thing I know for sure about MMO is that it smells marvelous! They need to make something that smells just like it for pancakes.

Then again, so will auto trans fluid.

ive done this on a few old engines, works well enough. i never knew people were using it as an additive tho, that never crossed my mind.

MM lubes the electric fuel pump and injectors.

LOL

First off, those two parts don't need "lubing", second, even if they did and MM lubed them, the next fill up would clean any lube right off.

I find it hard to believe that your engine would stay running given your claimed ratio. Also, MMO is snake oil, plain and simple. There are plenty of lab results to prove that fact.

I could be way off. I had no way of metering how much gas was being squirted into the carb. It was at idle though, probably 1200 RPM or so. Autolite 2100, bone stock 289. It choked a few times, but it would pick back up as soon as I slowed the pouring.

Yeah it smells good enough to drink.

 

[Raduque]

On a side note, is MMO transmission stop-leak any good?

My transmission is leaking from (seemingly) around the pan, and I just don't feel like futzing with replacing the gasket (though it probably needs a filter, too).

 

[LennyZ]

First off,You might want to actually open a fuel pump to see it does have wear surfaces.
They don't "need" lube but with lube it will last longer.

And every fill up is how you use it.Today's fuel with ethanol is really hard on these surfaces and MM does actually make these parts last longer.My daughter's Prius has 140k miles on it and i really don't want to spend a grand replacing the fuel tank because the pump went.It has a fuel bladder and it must be replaced as a unit.
Also provides top end lube which is a nice plus.

You might want to do some reading on this subject before commenting.

I've been a Certified mechanic since 1987,Also have first hand experience with people using these products for decades without problems.

If my fuel pump needed extra lubrication, the manufacturer would tell me to do so.

 

[LennyZ]

Doesn't need lube but it would make it last longer.
The pump is both lubed and cooled by the fuel.
Adding ethanol to the mix just makes it wear faster.

A pump is considered a wear item,not a permanent part.
At some point it will wear out.

Ethanol Wiki:

Several of the outstanding ethanol fuel issues are linked specifically to fuel systems. Fuels with more than 10% ethanol are not compatible with non E85-ready fuel system components and may cause corrosion of iron components.[189][190] Ethanol fuel can negatively affect electric fuel pumps by increasing internal wear,[190] cause undesirable spark generation,[191] and is not compatible with capacitance fuel level gauging indicators and may cause erroneous fuel quantity indications in vehicles that employ that system.[192] It is also not always compatible with marine craft, especially those that use fiberglass fuel tanks.[193][194] Ethanol is also not used in aircraft for these same reasons.

 

[Turin39789]

It's very good at lightening your wallet ever so slightly

 

[LTC8K6]

The fuel systems for most cars are designed to tolerate E10, so that should not cause any trouble.

I have read of lots problems when the content was allowed to go above 10% through poor controls at the supplier.

When they ram through that E15 mandate, well, I guess we can all just lump it if our cars can't stand it...

I would think ethanol would just help dissolve MMO anyway.

I really can't see how MMO would ever actually lubricate your fuel pump or help with ethanol blends.

It's again funny that Marvel Air Tool Oil, Lubricating Oil, Penetrating Oil, and Mystery Oil are all exactly the same oil.

 

[BW86]

I've only used marvel when winterizing my boats. Works well.

B.S.

The solvents in that stuff will cause more harm than good (if there ever was any good, which there wasn't) in today's cars.

You can THINK it helps all you want, but by the time your fuel pump does fail, you'll have spent so much on the MMO that you could have just saved it and just bought another pump.

 

[LennyZ]

Ok,So i guess the papers wrote on the subject of fuel lubricity are all wrong lol.

MMO is cheap,I'll continue using it as after all these years i have yet to see a problem caused by it.

 

[Andrew1990]

I just used some MMO for a small 6.5HP Engine that was rusted out. It kind of helped lubricate it but not by much.

Of course I got the can for free.

 

[SparkyJJO]

E15 mandate? Please tell me it isn't so...

Hey guys, let's require 30mpg BUT let's force the use of more ethanol that drops mpg! BRILLIANT!
