Ampco cylinder lubricator

[Werner]

Hello everybody, by chance I found this device. But I recognize - apart from the technical gimmicks, which is beautiful - no advantage of the device.

The unit doses by negative pressure, so mainly at idle and if the engine brakes down. So then if only little load is applied.

I always put 1/10 quart of 2-stroke oil in the tank for each tank refuel. Thus, the dosage is load-dependent.

What's the point? Do I have a misunderstod?

[J Franklin]

Yes when the engine decelerates it draws a minute amount of top cylinder oil, Marvel Mystery Oil used often in the U.S. but any good top cylinder oil is good. I think 2-stroke oil is too viscous. maybe light machine oil or auto trans fluid might work better if you cannot obtain true formulated top oil. There should be some form of flow regulation at the unit.

I believe Werner puts the 2 cycle oil directly into the gas tank to mix with the gas.

[Werner]

Good morning! Yes it is. Something two-stroke oil - synthetic without combustion residues - I fill directly into the gas tank.


My question was the unknown advantage of the Ampco-vacuum oiler, because he doses in my opinion at the wrong time (without engine load). I think the system is nice, but technically wrong.


Marvel oil is unknown in Germany. I dose the two-stroke oil + 1/2 can Liqui Moly "Ventil Sauber" (valve cleaner). These are the same additives as in gasoline, but very concentrated. Cleans very, very well.

Most Model A's never use, or used back then, any device or additive, and they survived quite well, so any extra lube is good, no mater when or where it is added.

People have used additives ever since the gas engine was invented. Those oilers were on many cars back when. Top oil keeps things lubed and free of carbon buildup.

Is that true? Info at the Marvel Mystery Oil:



The lubricant was used as a fuel additive in a Lycoming aircraft engine which was specifically cautioned against oil additives (Service Instruction No. 1014M, which also stated its use would void the warranty) which suffered catastrophic damage during take-off. The NTSB listed the probable cause of the accident as "The improper use of [a] fuel additive which resulted in a power loss."[3][5]
Auto manufacturers Ford[6] and GM[7] recommend against using engine oil additives, stating they are unnecessary in their contemporary engine designs and may void their warranties.

Hi, now I have installed this equipment. I will tell you after 500 miles, how it works with MMO.

[Werner]

Hello, I'm interested in who drives MMO for a long time, then what the spark plug faces look like. Mine are now dark silk sooty. Consumption about 3 - 4 ounces of MMO per 100 miles.

Thank you in advance for helpful explanations.

[J Franklin]

Adjust for less consumption. 4oz per 10 gallons or approximately 200 miles.

When I started using mmo at the 4 oz per tankful also noticed increased black deposits on my plugs. I put in some fresh plugs and reduced to 2 oz per tank. Helped a lot, still see a little increased black, but not the fuzzy stuff. Occasionally run a few tanks with out any mmo and add Seafoam instead, seems to clear the combustion chamber,

[Werner]

Closed Cab, please tell me, what is "Seafoam"?

[Y-Blockhead]

I always run SeaFoam, 1 oz per gal. Fuel stabilizer, removes moisture plus cleans and lubes... doesn't smell as good as MMO tho. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Hi,

Adjust for less consumption. 4oz by 10 gallons or approximately 200 miles.

Haha, it would be wonderful if my car with 10 gal would drive 200 miles. One tank fill is after 125 ml out to the exhaust. (Also with MMO! ;-)) -


I adjust that now to 2 ounces per 10 gallons. In addition I drive engine cleaner Liqui Moly 'Ventil Sauber'.

[30 Closed Cab PU]

Its a gas additive for cleaning varnish/deposits/etc, and does help stabilze gas.


Check it out being used on U-tube.

[Werner]

That is shown of the iridium-plugs after 3 miles drive with 50 mph and approx 2 ounces MMO pro 100 miles.

[mike657894]

running rich enough to get down to 12.5 miles to the gallon would blacken the plugs. I would think. get that carb fixed. unless your running a V8 and pulling a trailer.

Am not familiar with iridium plugs, carb looks like it I running rich, but are you sure teh plug is the right heat range?


Before going in and messing with the carb, how about trying the standard plugs used on Model A's?

[Werner]

Yes, the heat value is certainly correct, the lowest (# 5) available at NGK. I use iridium in all my 4 classic cars. The big advantage is the very good cold running and a better burning, if the mixture is not homogeneous or stoichiometrically accurate.

My question is to recognize the soot influence of the MMO. Therefore the question to MMO users. All top oils that are available in Germany pollute the burn surfaces.
