Any one use marvel mystery oil?

I use it in my gas.

Sorry, never used it. I've seen it on the shelves. Mind if I ask why you use it?
I use it in my gas too from time to time as an injector cleaner for preventative maintenance. When I do add it I run 1 fluid ounce per gallon or 30 ml per 4 liters of fuel, so about 9 fluid oz or 270 ml for a full tank added after filling. I've also used it in the oil during winter months when I've lived in cold climates. When it's colder than -30F / -40C almost any oil is like sludge on cold start ups. But now that I live on the Oregon Coast I don't have to worry about those kind of temps anymore (thank goodness).Quote:

I get mine at walmart or Mills fleet farm.
I know it's an old thread but +1 for MMO. I've used it for years and it's always been nice at making the engine just slightly smoother but then a few years ago I got a Blazer that had a stuck oil ring on a cylinder. After a few hundred miles I always had black haze all over the paint. So bad once I got pulled over by a cop who said I need to clean off my license plate, he couldn't read it. lol
Anyways after putting it in the oil and gas, after a couple hundred miles I believe it unstuck the oil ring because I never had the black all over the car again.
Otherwise it seems it may have made a difference again, read the following post.
I can say the mirage had a jumpy tach at idle when I first got it. Now at idle it's dead solid at or just under 750 rpms.

That's interesting. It reminds me of stories of adding kerosene to engine oil before an oil change in order to clean out sludge & deposits.
I've heard people believe MMO is just kerosene with some lighter oil. I can say aside from adding to oil, adding a larger than suggested dose to fuel results in a very noticeable smoothness to a tach after revving an engine and watching how fast it drops rpm's back down to idle. It's also how I got rid of a lifter tick in my miata.. They're known for lifters getting gummy.
I don't think I would ever use it.
Eh, to each their own.
I did have the thought the other night though, is there even an engine additive product other than engine flush products that are marketed as cleaners? I know lucas has the oil stabilizer. I did find it funny that I found at Walmart mmo has had " a new improved formula"! lol
I thought it was alright as-is. Makes me wonder if it was just a change of the label to remove 'MYSTERY OIL' across the front. Seems to be the biggest thing people make fun of. heh
I stick to using quality lubricants and change them at their intended interval.Quote:

I moved the discussion on Additive Comparision to another thread. It's a good question that deserves it's own space.
It can be found here: Additive Comparison
So that's interesting, another guy here said he uses Sea Foam in the oil. I never thought about that or noticed if it does say it, it's used for that. He believes it's terpentine.
Any chemical engineers around that would be able to theoretically analyze the difference between terpentine and kerosene in the engine mixed with oil? I don't know enough about either.
Scotty Kilmer sort of comes across as nut case, but he makes good points sometimes. You only have to watch the first 1.5 minutes of this youtube.com clip to get his points.Quote:

If you don't watch the clip, this what I got from it. SeaFoam came out in the 1940's (1942). It was created to help clean out 2-stroke outboard boat motors primarily. I don't think fuel injectors were very popular during World War II.
A second point comes out in his discussion. Fuel injectors do benefit from a nitrogen based cleaner & Techron is a nitrogen based cleaner.
I came away with this. My chainsaws may really benefit from using some Sea Foam in the gas. My Mirage might like a shot of Techron from time to time.
I have a USB endoscope camera and use it for checking on carbon buildup. Each year, I remove the injector bank and insert it through the holes for the injectors.
This car is almost five years old, and has totally zero carbon on the valves and in the intake system. It is perfectly clean, no need for any additives here! Our cars do not have direct fuel injection, so the injectors are before the valves, hence they stay clean.
Well that's good to know! What is the type of fuel injection these cars have?Quote:

It's not direct injection, if that's what you're wonderingQuote:

Direct fuel injection has the advantage of lower fuel consumption. Disadvantages are more complexity at higher expense, very much higher levels of minute particles in the exhaust fumes, and a tendency of intake valves becoming full of gunk due to the spray of fuel entering the combustion chamber directly, instead of the intake valves being sprayed and cleaned by the solvent action of fuel. Various direct fuel injection cars have a long history of becoming fouled up and repeatedly needing expensive repairs! Ours do not have these problems.Quote:

3.) Our cars have soundly built highly modern engines! The original 3A9x / 4A9x design came from a partnership between Daimler (MDC) and Mitsubishi. Those engines were built into the European Colt, the Smart For Four, and some others. That original design was later modified by Mitsubishi for our cars, but was also the basis for some later Mercedes engine products, as well as for a new and efficient Renault engine that is found in some Renault, Dacia, etc.
The 3A90 / 3A92 are very well and thoroughly designed engines, meaning an unusually high effort was put into the design. They will last very long if serviced properly and regularly. They have no tendancy of valves or piston rings becoming fouled-up. We don't need hocus pocus or any extra miracle wonder stuff for the Mirage.
Don't know yet. I'm just a nerd like that.. :) I love to learn!Quote:

Thanks for that, I love to hear more info!Quote:

Who looks at door locks any more? We don't even use them when we are in the car. We push a button (whether on the remote or the door itself) to operate them. I am just using this as one example. The examples like this are endless.
Lol I saw the negative review because of the door locks. Total hogwash. I think that was the guy to give it a negative rating because he could see his foot through the engine bay. Then he compared it to a hellcat. :-|
