Default Marvelous Mystery Oil?

Some have reported adding to gas.

It lubricates the valve train better than just regular old engine oil will. it is suppose to make your valves last longer in the long run. Ive never heard of someone actually say a set amount to put in per gas fill up. But if i were to use it every time i filled up i would say roughly 6-8 fl oz. Its not to much, but its enough to lubricate.

The container has recommendations for how much to add to the fuel tank ( believe it's on the order of 2 oz to 10 gallons Gasoline ).

Folks with Model L Gravely tractors swear by to prevent the exhaust valve from sticking open...

Never heard of it doing any harm.

I use it in my old iron; have never sprung for the "Marvel Inverse Oiler" ( or Ampco Cylidner Lubricator )... just add to fuel.

Today I went to the fabric section of a store to buy some beaded trim. I told the worker that I wanted 8 feet. He stood there with a puzzled look and said "8 feet.............how many yards is that"? I said that would be 2 yards and 2 feet. He then proceeded to lay the trim on the yard stick imbeded in the cutting table, and measure off two yards and 2 feet.

It's a reasonable solution to the increase in alcohol in today's fuel. Prevents sticking valves. I ran an ampco oiler on one of my cars and enjoyed the dismay observers had when viewing the gadget under the hood. I would call it my "super sauce."

I believe the can says 4 oz to 10 gallons, which is what I do regularly.
Its like the glousamine I take for my arthritis.
You don't know if it works but everyone swears by it, and no one says its bad.

I never used MMO or had a stuck valve in a flathead especially a rebuilt one until two years ago, the ethanol in the fuel must be the reason it is becoming more common now. Probably only had a couple hundred miles on 59AB engine and it ran fine in the morning going to local car show.After sitting all day with the hood up in about 90 degree weather it started and ran terrible driving home,missing and backfiring like the timing somehow was off. Remembered reading about this on the old Ford Barn and next morning tried the MMO down both sides of the carb with engine idling,took it down road and it cleared up and ran smooth after about a 1/2 mile. I put the prescribed 4 oz in 10 gallons every fillup now,I am a believer. Also I have heard that 10% ethanol is enough alcohol to contribute to tank or fuel line rust and in my mind the oil may help against this.

A mechanic told me that today's ethanol gasoline is too 'dry' for the old cars and will eventually cause the valves to stick. The older gasoline formulas lubricated the upper cylinders and valves. Not so today.

Does it actually work? Well, for me it seems to so what the heck, 4oz. per ten gallons and I'm good to go. Half a quart in your motor oil at oil change time is supposed to help too, but I shy away from adding anything to motor oil I guess MMO is OK.
I believe that half a quart is just before the oil change. I believe MMO contains solvents that will clean some of the sludge out of the engine. I used it since my Ford 8N days and in the diesel fuel of my case backhoe. It's a good product. I would not put it into new oil either.

How big of a problem is sticking valves? I have 3 model A's. They are sometimes driven frequently and sometimes set for months. I have never had a valve stick just using 87 octane pump gas mostly with alcohol.

I think sticky valves can be more of a problem in fresh engines, than in high mileage engines. Tighter tolerances seem to be aggravated by the higher alcohol content fuels. We see the problem fairly frequently in the V8's. Much discussion on this issue on their forum.

Russ,
In all the discussion that you've encountered on this subject, have you heard any involving sticking valve...when stainless steel valves are used in an engine?

Hello all. I work on a U.O.P.fluid catalytic cracking Unit. We make what is called a cat gasoline. unleaded with a octane of 93. There are other units that produce higher octane.Other products are blended to bring down the Octane.Such as Naphtha, propane,butane other light or heaver products,depending on the time of the year(hot -cold) Down stream of us is the Gasoline hydro treating unit known as G.H.T unit this removes The sulfur
from the Gasoline.(GOVERNMENT REGULATION) Also makes it dry.Then the alcohol is added. yes a lubricant will help all engines.

Oil also keeps things newer longer and has unstuck my valves when the engine was rebuilt.

I've heard about two issues with alcohol-blended fuels: one has to due with increased tendencies to turn to "varnish", the other is corrosion due to the water content of the alcohol...
