Another testament - the guru of 'Atomic Four' engines 'Don Moyer' reccomends the MMO to keep valves from sticking.
A4's were 4 cylinder Universal Tractor engines converted to marine use.
I have one of these 33 yr old engines in my sailboat, and 50+ yr old ones are common.
Don swears by MMO. www.moyermarine.com

Owned a boat once myself, the nautical definition of a boat around a lot of folks who own one is "A hole in the water you throw money into . . ."
I'd have to pretty well agree!!!

Anecdotal evidence is worse than useless. If I was diagnosed with cancer and realized the previous day that I ate an orange. Went on the net and found out that lots of people ate oranges the day before the bad diagnosis. Obviously useless data.
Only with well designed, independent, testing under various conditions could any additive be deemed useful, harmful or just a rip off. This was done with several of the widely advertized aditives which were taken off the market or forced to change their ads.

I think "faith" is the key word here. Doctors used to advertize cigarettes and morphine was a wonder drug. MMO may very well be good for some things. However, in that 85 years, has anyone ever seen any real test data?

Probably been tested in millions and millions of cars in the past 85 years. Who needs "test data" the stuff works. There are millions of believers and nary a disbeliever (excepting perhaps you). My 67 year old 40 Chev has whistle clean cylinder walls, no ridge buildup and clean valves. It is the original engine. Next case

Per the MSDS sheet, Marvel Mystery Oil contains:
Naptha 70-80%
Mineral Spirits 20-30%
Di-Chlorobenzene 1%
Not much of a "mystery"

Anecdotal data again. Forgive me if I'm skepical but untill I see a real test. If the makers of MMO could run several engines with and without the product and show the difference ( under independent control) they would. Until then I will remain skeptical.

), there is one available online for every chemical and product containing any type of chemical and/or petroleum product available. They are a required publically available document, and every auto parts store has them for every product...or they face penalty. However, ya gotta ask to see them sometimes. An MSDS will give you material composition, risk assessments, environmental problems, safety concerns, clean-up information, information as to hazardous ratings, etc. There are no "mystery" products anymore...unless you mix it yourself or pick it up from Bubba who mixes it up in the sink..... Science is a wonderous...and mysterious thing....

I've been using in longer than I can remember. I believe it keeps the tops of the cylinders lubicated against corrosion but I use it mostly as a substitute for lead which lubes the valves. I think it also keeps your exhaust system in shape longer. I've owned my 65 for 19 years and put 16,000 miles on it with mostly short trips and its still like new.
As far as the cost, I load up whenits on sale. It's cheap stuff.

If this was in the mid-late 70's, another testament to GM engineering was they had an epidemic of camshaft and crankshaft failures in the lower 49 states.
QUOTE= There was a cam lobe wiping epidemic. To counter this, they added the ATF and increased the curb idle to 1000 RPM. They would knock, shake, groan and make weird noises. Those engines were abused so bad, it is a testament to GM engineering.[/QUOTE]

I would say this about MMO. It is an excellent penetrating oil. I've used it to free stuck rings and valves in old engines when even repeated oil changes wouldn't do a thing. You can take an old engine that has sticking valves to the point it will hardly run when it's hot. Add the MMO and run it awhile at low speed then open it up. Stand back and watch the crap fly out the exhaust. I've done it on several old engines and saved the cost of a rebuild. But, I did it with Casite once too. I believe automatic transmission fluid will possibly approach similar results.
I don't need any scientific testing to show me it does what I stated. I've seen it work and it works well for it's intended purpose when used as directed.

Mmo
MMO is the best air tool oil that I have ever used. For 30 years I have used MMO on wet or locked up air drills and grinders, it worked so well that I use it in my air line oilers all the time. I also add 1/2 Qt to the BB after a change.

After the original thread (way back) decided to pick some up. Cheaper then I thought it was going to be.
Will be trying it this Spring to see.
Will try it as a penetrating oil too. Someone here posted ATF + Acetone as the best penetrating oil (some controlled test result) so maybe I'll just use MMO + Acetone.

I thought E85 is corrosive, requiring special fuel lines and fittings on new "E85 compatible" vehicles. So I suspect a stock C2 would have vulnerable components that might leak and cause a fire.
At the very least, I expect you'd have some tuning issues.

No, the old leaded fuel had lead (TEL) in it that bonded to the valve seats and valves, and that provided a cushion so that the valves/seats did not erode (as quickly) or recede from the sudden valve closing pounding (although stock Chevy cams have very soft closing rates, and almost never see recession issues to begin with!). I doubt that the lead did much in the way of lubing the stems or guides, but it did not hurt (in that regard). Adding a true liquid lubricant to the gas (Marvel or ATF or whatever) is not the same as adding lead to gas. Different effects, unless they contain TEL which is essentially banned. Adding a liquid lube to gas will not help the seats whatsoever.
Just because a well known guy says the earth is square does not make it so. Leno's experience with old cars is well known, and if something works for his purposes, then great. But that does not make it the right thing to do for all of us. The car makers have tested Marvel, Bardahl, STP, Steed, etc., etc., etc., and have never endorsed any of them. There are certainly times when a particular chemical can help solve an issue, but the fact is they are very, very limited. How many engines have you seen blowby problems fixed with "Restore"? If you wish to believe in liquid magic, then go ahead and spend your coin.
