Marel makes a device called an Inverse Oiler. It meters a precise amount
of MMO into the mixture. The amount is variable.
I think this would be terrific on aircraft if you want to use he stuff.
BTW for years I used nothing but MMO as a 2 stroke oil in motorcycles.
It mixes with gas and burns very clean. Plugs lasted longer and never
had a seizure.
I think it is a great product

Sorry about the typo. It is the Marvel Mystery Oil company.
Actually I have one of these inverse oilers. It is new in the box and
was actually produced back in the 60s.
I'll let it go for $90 including postage.
If nothing else it is a nice vintage piece of petroliana.
Thanks

Thanks for the quick response. I'm not in the market right now, but I'm
on the Wankel rotary a/c list, and a lot of these guys would like to
find a reliable metering pump to avoid manual mixing of 2 stroke oil
with gas for apex seal lube. If it's ok with you, I'm going to forward
this info to the rotary list.

Sounds good to me. If someone can use it I would like to sell it. It
works by using the engine vacuum to draw the oil from a reservoir. So as
the engine vacuum drops with rpm increase the oil flows heavier and vice
versa. Hence the name Inverse Oiler. Makes alot of sense.
When I was in high school my auto shop teacher was a devotee of MMO. He
thought there was no finer oil and if he were ever to run a demolition
derby that he would use only MMO because the engine would still run cool
even with a loss of coolant. That was his opinion of course but he was
an old time mechanic and one smart guy who I respected very much. In
fact he taught me to really love the mechanical arts. There should be
more teachers like him. He was a tough and kinda scary guy but if you
didn't screw around in his class he would share all of his knowledge
with just a couple of guys each semester. I was lucky enough to be one
of them

Some sort of pump sounds like a good idea but MMO? Try putting some in
a cat food can and bake it in your oven for one hour at 500 degrees.
Do it when your wife is out of the house :-) Worst stuff of all
the oils we tested. Two cycle oil is very good as is turbine oil and
the synthetics we tested are much better than regular engine oil. MMO
is near the bottom of the list. Another test is burn a bit and
see what kind of residue it leaves.

INVERSE is right!   The oil input is INVERSE of what a two stroke or
rotary needs.  This would be fine for top cyl lube of a 4 stroke motor,
which is what MMO has been touted for for 60 or 70 yrs.  They
have a normal oiling system for the moving parts and this is just an
auxiliary oiling system to help with topend (valves etc).  You need
MORE oil at low manifold vacuum (wide open throttle) and less
oil at high manifold vacuum (idle) for a motor which is getting ALL
its lube thru the fuel.  I would not trust this for a highly
loaded two stroke or a rotary.
