Marvel Mystery Oil

Recommended Posts

Do any of you use Marvel Mystery Oil in your cars. Most people nowadays do not even know what it is but a few old timers that I have meet throughout the years have sworn by it.

Walmart has it in quarts for about $4.50. I put about 4 ounces in every tankful of gasoline. My mechanic says it is the best protection money can buy. Wayne

I've got three cans in my garage and I haven't been attacked by a yetti in months!

Actually, the stuff is about the closest thing you can buy today to the oils that were sold for use inside S.U., Stromberg, and Solex carburetors. It does a good job of damping the needle without overdoing it and making their response sluggish.

I add four ounces to every tankful on the Roadmaster. It might be the reason I've never had vapor lock, even in 90+ degree summertime driving.

It helps lube and keep the valves cool, something the lead free gas does not do, Especially flat head engines and the Buick nailhead engine that can't have the valve seats hardened.

Dad swore by the stuff. He had a 1940 Cadillac that had a Marvel Mystery Oiler on the firewall. It fed MMO into the intake.

I also add some to the crankcase a few miles before each oil change.

I get mine at NAPA. The new bottles don't have instructions on them.

We neither recommend nor recommend against use of any additives. We do what the customer wants. I do have to point out that 4 oz of MMO in 20 gallons (2560 oz) of fuel works out to 1 oz of MMO/640 oz of fuel or 1/100 oz/6.4 oz of fuel. Basically 1 drop in a teacup. In my mind it is difficult to understand how it can have the effects ascribed to it.

If it makes you feel good use it. The better one feels, the better the stories. And it is magic, you know, with a real neat label.

Let's not get into politics again guys. We all should be sick of politics for one year.

I understand your point

But, there's no denying that MMO smells good

It does, don't it! To bad it doesn't make the exhaust smell like wintergreen, that would be something. I'll just have to be content running it under my nose once or twice everytime I crack a can open.

I will say that the fun factor decreased when they went to a plastic bottle instead of the metal can. Now I have to top up my used metal can from the plastic bottles I buy to keep everything kosher in the garage.

I put a healthy squirt in the inlet of my air tools before using.

The "OLD" directions were to add 4 oz of MMO per every 10 gallons of gas. I still follow that guideline for my cars since I don't know the long term effects of no-lead ethanol (corn) gas. If it costs me a few bucks for the amount of driving I do, well I guess I might have wasted that on having pie and coffee a few times, or buying raffle tickets for a charity which gains more than I will lose. I believe that it doesn't hurt the car and MAY do some good. If it does not help,then at least I feel better about it. I usually but it by the gallon and repackage to travel cross-country with plastic quart bottles.

We drove our 1941 Cadillac more than 3,000 miles between Labor Day and Halloween, using Marvel Mystery Oil, Alemite CD-2's lead substitute, and Star-Tron (for the ethanol gas problems and for long-term storage). The car ran great, and is still doing so. A few years ago I left the gas tank of our 1988 BMW 528e with only ethanol gas and I'm still paying the price with having to replace the tank, fuel rail, injectors, etc -- very expensive.

My Dad always said that on ounce of prevention was worth a pound of cure......

I always like Rislone Oil Treatment myself. This was after purchasing a 1963 Imperial LeBaron in the early 1980s (20-years old) and upon opening up the valve covers to replace a gasket it was just as clean as the day it was built because the owner (original owner I purchased from) changed the oil every 3,000 miles and used Rislone every time too.

I use it for lots of things around the shop as well as in engines. Most recently I poured a good bit into each cylinder of my stuck Essex 4. Two days later it was free. Probably several other products would have done the same thing but they don't have "Mystery" in their name.:cool:

I always wondered, does Placebo come in different strengths and is there a generic version?

Yes there is a generic but buy the original, the more you pay for it, the better it works. That is just the nature of the product.

I was told years ago by a conservator/restorer that oil of wintergreen - methylsalicylic acid or methyl sour - is the best penetrating oil there is. It also makes your work smell nice and clears the sinuses while you are on the job.

No wonder people like it. Chloroform is an anaesthetic and highly volatile! Calms your troubled mind before putting you to sleep.

Take care using this stuff. Carbon tetrachloride used to be used in dry cleaning. It is highly carcenogenic. This will be where the purported cleaning action comes from, perhaps.

When we were put onto unleaded high octane fuel (no ethanol yet) I ran kero about 1 to 20 in my 1930 Dodge for a while. After a while I couldn't be bothered and noticed no differencee without it. After all, unleaded fuel was all there was in 1930. I also tried a lead additive - the spark plugs lasted 1000 miles and then failed. Pretty much all of them at once. So no more additives.

If I plan on leaving it for a while, I squirt some Shell Ensis into the carb. before shutting it down. Ensis has very high surface tension and wicks its way into small spaces. No stuck valves with Ensis. An aero museum in Christchurch inhibits the aircraft engines with Ensis. The only down side is the smoke.

Lots of 2 stroke engines run on 50:1 gas oil mix. If that is enough to do all the lubrication of a 2 stroke engine, I don't see why 640:1 wouldn't have some slight effect.

And don't forget......"one half of one GREEN M&M." per tank full.
