Fuel is dry. With UCL adds a little is fine. More is not always so. YMMV.




Not quite - MMO is not allowed on 2007 and newer diesels because of the ULSD requirements.

MMO has about 500ppm of Sulfur in it (derived from MMO forum data on how much ULSD is raised when in use) - and using at the prescribed treat rate, will raise the ULSD slightly over the Sulfur requirement for ULSD - therefore they are not allowed to recommend it.

Also - while normal treat rate for MMO (gas and diesel) is 4 oz/10 gallons, Rich Kelly normally recommends 6 oz/10 gallons for diesel to get additional lubricity benefits beyond what diesel already has (it is already somewhat lubricious to start with). 4 oz/10 gallons is enough for gas as it has very little lubricity to start with and gas engines are designed to handle "drier" gas (fuel pumps and fuel injectors).

MMO is also a very good diesel additive, but due to the constraints above, cannot be recommended for diesels that require ULSD.

I'll look at it this way, if spending less than $3.00 and spreading the $3.00 over a months of fillups makes me happy at my ripe old age of 66, so be it.

The money I don't waste by buying bottled water I can use to purchase a bottle or two of Marvel Mystery Oil.

Oh Yes, I do think the engine runs better, but whether it does or not if it makes me happy, its better than taking one of my perscription drugs.[/quote] amen brother im voting for u, now break open the 50 cal and lets have some fun,,,lol
 
There is a much better reason that MMO should NOT be used in any Diesel engine's fuel supply. It has actually been shown in lab tested study to decrease the lubricity of diesel fuel. This was USLD it caused the rating to actually drop a considerable amount.

At a base HFRR score of 636 adding MMO caused it to increase(increase means a drop in lubricity)678 or 42 points.

Here is a link to the study. Not sure if this has ever been posted on here but figured it must have but just in case. DIESEL FUEL LUBRICITY ADDITIVES
STUDY RESULTS

Don't waste your money or time with MMO in your fuel system..

A bottle of Chevron Techron Total Fuel System Cleaner, Red line SL-1 or Regane Complete Fuel System Cleaner will actually remove carbon deposits because it has proven PEA detergent in it.

MMO can't prove any cleaning claim with documented tests.
 
i believe ya and the things u listed deff clean i love em but i also love mmo in my fuel my car loves it and runs better and gets better mpg but im just curious if its makeup what its made up have anything that might help clean
 
This might help: I've pasted it a few times over the months, it gives an idea of MMO's make up.

Keep in mind MMO helps keep injectors and the fuel system clean, its main purpose when added to fuel is its UCL properties. If you want to clean a fuel system add Red Line's fuel system cleaner, Regane, Techron, or one of the other cleaners first, then use MMO. Even their tech guy Rich Kelly will tell you that.

HTH

I borrowed this from another thread, I've pasted this into a few threads before HTH.

70% Light Aromatic Oil (Pale Oil)
- It is a Naphthenic Oil, so while it oxidizes faster than a Paraffinic oil, it does clean and dissolve sludge and carbon well and cleans up after itself from any oxidation. serves as base oil as well. [Naphthenic oils have more solvency and are more polar (they are attracted to metal more), but oxidize faster.

29% Mineral Spirits
- Cleans Varnish very well. General cleaner. Also acts as an antioxidant.

38 parts per million (ppm) Boron
- AW/EP agent, friction reducer, antioxidant

900 ppm Phosporous
- AW/EP agent

1/2% 1, 2 ortho-Dichlorobenzene
- EP agent as it interacts with Iron to form an Iron chloride barrier under any ZDDP or other AW additives. Also very good cleaner/solvent, and friction reducer

1/4% 1, 4 para-Dichlorobenzene
- EP agent as it interacts with Iron to form an Iron chloride barrier under any ZDDP or other AW additives. Also very good cleaner/solvent, and friction reducer

Oil of wintergreen - for the scent
- Not just for the cent, is also a cleaner. may aid lubricity.

Red Dye - for the color
- well this one just colors the stuff
 
I thought I'd post my experience with MMO.

I recently developed a bit of main fuel pump noise in my 1981 Turbo Volvo. I've owned the car since new, so needless to say, I'm very familiar with the car. It has 240k miles on the odometer. This is its second pump. The pump noise, noticable only at idle, resulted in a slight vibration at highway cruising speeds in overdrive. In essence, the pump was varying the pressure on the fuel injectors. The Bosch K-jet injection system is mechanical, as opposed to electrical, and extremely sensitive to deviations in pressure. The slightest deviation will lean out the mixture and show up in overdrive on the road as vibration in the drive line as the engine struggles with the leaned out mixture.

That said, I was on a vacation road trip when this developed. I remembered reading about MMO here, purchased a bottle and added 5 ounces at the next fill. I noticed the vibration beginning to subside tank-by-tank as I added 4 ounces at each fill. By the 5th fill, it was gone and the pump was quiet. In addition, the idle smoothed to the point where it is now the absolute best it has ever been.

I am now on my 6th tank and I am going to buy it by the gallon. I've made the decision to continue to use it as a preventative measure as I am very pleased with the results. As an aside, my wife, who noticed the vibration when I brought it to her attention, also noted the subsiding, the reduction of pump noise and the smoothness of the idle. Traveling on the road, one gets a good 'feel' for how a car is running and she certainly 'felt' it.

Frankly, the car has never run so smoothly. I would not have known about MMO had it not been for this forum.
 
Glad to hear it. A lot of first time users report similar good results with MMO. It does the same for my truck, smooths out the idle, and it runs nice and quiet. Plus MMO helps conteract some of the negative effects of the ethanol in the gas we have here.
 
Thanks for that. I was very pleased on my road trip. I have used Chevron gasoline exclusively since new and I have always used a bottle of Techron before an oil change. MMO smoothed out the idle and the 'runability' in a very profound way and it is also now a welcome part of my regime.

Okay, seeing that biodiesel is the best additive to increase lubricity in ULSD (according to the study, which is have no reason to doubt), what happens if you add say four ounces of biodiesel (B99 or B100) to a tank of gasoline? Why wouldn't it give the results, or even better results, so many claim for MMO and other additives?

You come into every thread about the MMO and discourage other BITOG users from using it. Do you have any experience with it? If not, you really can not offer an educated advice, can you?
 
I just added Seafoam to my induction system through a vacuum port along with the spray foam through the throttle body. I let it sit for about 15 minutes to soak. When I fired up the engine, holy smokes (pun intended) did the car smoke. I drove it and it smoked for a good 10 minutes on the highway until it completely cleared up. Just before I got on the highway, a woman took my license plate number down to report me. I called the California Air Resources Board and they were surprised that this product was for sale. Apparently the VOC law prohibits any product that produces smoke from the tailpipe. What an experience that was I gotta tell you.

I'm thinking of adding it to the fuel system before an oil change. It should be a gradual and less dramatic clean. I intend to continue to use MMO on a continual basis as I really like what that does. I have been using Techron before my oil change but this appears to be very powerful. My visceral impression is that the engine runs as smooth as it did when I bought the car. Very satisfying this...

I've been wanting to try this very thing, but I have no idea where to find Soypower B100 around here. I would probably do more like 16oz to a full tank of premium in my car.

That smoke is nothing but the light aromatic oils from the MMO burning off ...it's not doing any substantial cleaning of note.

Because I hate to see a person throw their money down the drain on something that can't prove it has effective carbon cleaning agents in it, while for the same price or less you can get a proven product that WILL actually do SUBSTANTIAL CLEANING.

MMO simply can't claim that...While Chevron Techron, Gumout Regane, and Red Line SL-1 all have high concentrations of PEA detergent that are proven effective at cleaning those carbon deposit out.
