Re: MMO in the Gas
Guy Lumbago? Ha! Guy Lombardo was an avid hydroplane racer in addition to his main gig leading the Royal Canadians dance band and playing Auld Lang Syne on radio, then television, on New Year’s Eve. He also ran over my paternal grandfather and maternal grandmother with his Jaguar in the wee hours of the morning on a rainy December 9, 1951 in Glendale, NY. My grandfather did not survive. I’m not making this up.
Whew. Now I’ve done my part in extending this forum post. |

Re: MMO in the Gas
I use MMO between 4-6 oz per tank in my daily driver A pickup and I do it for four reasons. 1 it helps prevent vapor lock, 2 it keeps the carburetor clean while its running, 3 it coats the tank and prevents rust in the first place. 4 it slows down the combustion slightly allowing you to get a bit more economy out of it. I did a 165 mile trip running with 4 oz of marvel mystery oil. 45-50 mph on full spark advance, gav fully shut and "cruise control" on. I used 7.9 gallons for the whole trip. that's 20.7 mpg. I probably could have done far better if I had stayed at 40-45 and not idled at stops. but all in all, I am a believer in MMO, my question to critics of the stuff, what's the harm? if you don't like it you don't have to use it. Why not at least try a controlled experiment with and without it and see if it works like it says it does?

Re: MMO in the Gas
X2 on Sunny's views on MMO especially point #1. Point 2 is good for cast iron Zenith carbs, will prevent rust from forming.

Re: MMO in the Gas
How does it prevent vapor lock? How does it slow down combustion?

That's something that can be explained by physics: by putting higher hydrocarbons into the mix which have a higher boiling point and lower flame speed. Is the lower flame speed wanted? I wouldn't think so... A lot of the other claims like 'cleaning' and 'rust prevention'? well... |

We tried it in my wife’s Land Rover. The check engine light came on after a few miles. Dealer said there was a fuel problem code. They didn’t recommend using MMO and reset computer. After a few miles the Light came on again. After a couple of gas fill up’s, check engine light stopped coming on. I guess the computer in our Model A’s isn’t as sensitive as the cars today. Enjoy. |

Re: MMO in the Gas
The addition of MMO has many implications.
The highly distilled white oil used as the basis ensures passivation of the surfaces and also a certain amount of lubrication in the entire area from the tank to the intake valve. The detergents contained in it also ensure that old deposits are gradually removed and platelet-shaped soot particles cannot form crystals because they flake off beforehand. The combustion process itself is a little bit delayed, since the stoichiometric ratio due to the oil admixture leads to a somewhat delayed flame speed of the ignition mixture, to the detriment of the oxygen atoms. (This is rather leisurely anyway at 25 m per second.) That's why we old masters knew the trick of pouring some two-stroke oil into the tank in the event of knocking or knocking combustion.

Re: MMO in the Gas
X2 with Werner. I have done the same thing with highly filtered used motor oil. I add it in at 4 oz per tank if mmo isn't available. it works the same way, and it is a good use of your old oil. All you need is a 5-micron filter sock and a bit of Patience. I dilute the oil with some gas that i use to clean parts and so on. it gets mixed up and the contaminants removed with the filter. once I do that it comes out clean and I run it like marvel. no fear of smoke and it works well.

Cars, including A’s have run fine without this stuff, just like they do without lead in the gas, zinc additives in the oil and fancy velocity stacks in the carbs. Adding 4oz to 10 gallons doesn’t do anything either way, it’s so diluted at that point. The diehard users should go a full season without it and report the difference. |

Re: MMO in the Gas
If you do not want to use MMM that is your choice. It works for me and many others so I have faith in the product.

Well I went a few tanks without MMO as I was out and the car just seems to not run as good. I dumped in 5 ounces and filled her to the top and when to a cruse in. On the way home I noticed how the car just seemed to run better. Not sure if MMO increases octane but it sure does something to the gas and with the benefit of preventing rust I see no reason not to usee it but thats just my opinion. |

Re: MMO in the Gas
Maybe the diehard naysayers should also try MMO for a season and also report. It could be formatted as a survey this winter for laughs and insight.
