MMO in the Gas

Some use ZDDP zinc additive for flat tappet motors since zinc is banned from fuels due to catalytic convertor issues with zinc. If there is test data for all these additives, it would be good to see them.

I thought ZDDP was added to the oil. Lead was banned from fuels. I don't believe zinc was ever added to gasoline.
 
I was watching a video that Paul Shinn had about cleaning a gas tank and he said a little MMO in the gas helps prevent rust.....sounds logical to me

I see plenty of gas tanks that come to me for restoration after folks have tried all of these remedies that seem to counter that logic. One being MMO! I've even had one come in where they read/watched/whatever somewhere how some authority recommended using POR15 on the inside of the gas tank to cure the rust problem. :rolleyes:

Maybe it’s like taking CBD. No one can really tell you how or why it helps, but for some people it does.

MMO seems to have worked for me. In one of my cars there was no other reason that the valves would have freed up and quieted down.

Enjoy.

If you changed the oil and are driving it more, that could explain what happened to your car. Without performing controlled tests, there is no way to document whether it works or not. I use it too, so I am not opposed to it. Anecdotal stories like those here are nice, but they are not rigorous tests.
 
I know some love MMO and some do not but regardless I think keeping the gas tank full helps assuming your tank is in good shape......and i do not see how MMO hurts.

With all due respect, I think personal experience can be interpreted as "knowledge". It seems like most of the posts on the several pages of this subject are mostly based on personal experience, whether positive or negative. A product that has been around a hundred years certainly has a strong and loyal customer base to survive, spanning several generations. Not too many products can boast about that. Whether it's a great product, or snake oil...people still buy it because they think it works.

I owned the car that I am referring to for 43 years. The first 20 years I did not use MMO or HD oil. Switched over, and within 100 miles most of the valve noise went away. Within 500 miles it was gone. Sold the car last year, no valve noise.

A few years ago I purchased a car that had been sitting for a number of years. When we started it up it sounded like the valves were going to explode. Changed the oil to 20W-50 HD and put MMO in gas. After about 200 miles noise was almost gone.

I don’t need rigorous tests. I like first hand results. We’re not going to the Moon here.

Enjoy.
 
A funny story... I know this MMO subject has been beat to death, but it reminds me of someone I met many years ago. I was in a pizza parlor and when I went to pay the man at the register, I slowly reached out my arm and said my elbow has tendinitis (tennis elbow). The man at the register said "Oh you should rub some WD-40 on it" I said "What"? He said "Yes, I use it all the time for my arthritis". I said "You actually put it on your skin"? He swore it works. I know the makers of WD-40 would be the first to disclaim topical use, and there are no clinical studies to support this, but this guy would go to his grave claiming it worked for him...and who am I to say he's wrong?

Well, did you try it? Maybe it does work! :eek:

Upper cylinder lubricant as we used to call it smelt like almonds. Does MMO smell like that? I've never seen it here but I looked it up. A one US gallon (3.78 litres) pack cost $100. I guess I'm not in a hurry to find out how it smells.
 
MMO works so good it freed up a stuck distributer for me. I bet if you dumped some in an empty tank and let it sit in different positions it would remove rust.

I am not sure if we are all playing a game of oneupsmanship on 'To Tell a Story' or what, but I'm gonna ask this as if we are being serious in our storytelling.

Therefore, EXACTLY WHAT did the Marvel Mystery Oil do to "exploding valves" (-whatever that sounds like?? :confused:) to make the exploding sound go away? Since the Model-A engine uses a mechanical tappet, it generally is excessive lash clearances that causes a valve noise. From my vantage point, it is more likely that a higher viscosity oil would cushion the impact of the tappet hitting the valve stem, ...yet I would think that MMO being a thinner viscosity, it would not help in abating that valve noise. If that was not it, then what other scenario would cause the valves to explode??

I was just using the word exploding to over emphasize the clatter that the valve train was making.

There were no explosions going on with the exception of normal cylinder firing.

My point is that there very well could be a correlation in using MMO along with HD oil to help free up your valve train. Slow, sticking, worn.

Say whatever you like! I really think that it has worked for me. The proof is in the pudding. Valve noise was reduced significantly. That’s all I cared about.

Enjoy.

Im not going to go back through 5 pages of posts to find his name, but I’m with the guy in a previous post who said that after he puts it in his gas tank, he splashes some on like cologne.

I remember that one! He said it attracts women. (LOL) I'm thinking mosquitos too! Seriously...how long is this post going to last? I know I'm not helping to end it.
 
When I was a kid “Guy Lumbago and his Orchestra” played at Jones Beach… he was a spokesman for Marvel, why his last name alone sold gallons..
