Metal Lube - Magic oil ??? only 7% !!

Hello Ken, Metal lube is not expensive 17$ / 1 l
And think that you need only 6%
I used klotz and motul micro 18 % and cost 22$ / 2 l

About Castor oil is available and easy to find.

I have known people to run crazy low oil loads and have excellent performance, and reasonable engine life, from speed planes.

My cousin's argument is something like :
Full size boat engines are running 50:1 to 100:1 without problems (2%, 1% oil content)

There is a difference in construction of the engines, with all needle bearings except the piston rings to cylinder instead of metal to metal journal bearings on marine outboard engines.

His experiments and competitions were with "modern", or at least in current production, model engines and to the best of my knowledge he did not blow up any engines, although he could have simply not mentioned that he did. I don't know the actual oil he used, but I know he mixed his own fuel. The engines were also in his mind "disposable" but he also races, switching between sand rails and oval track, so everything that can be bought or made is disposable.

This was on RC world in 2008 I think.... http://www.rcuniverse.com/forum/glow-engines-114/1193147-metal-lube-really-good-stuff.html I dont think it is going to replace castor or make a differance in your overall runs >

Hi Eric, I don't want replace castor, I want replace 7% metal lube by 18% oil sinthétic like klotz ...
Or maybe use as aditive anti friction

Thank you Eric I see that it is not Magic, not miracles, it is bases in teflon, and can cause glow plug contamination.
Maybe as aditive for any purpose ???
I don't practice competition only sport fliers :-)
But I don't like cleaning toó much castor after flight :-(

Here is the undeniable proof that castor is your best oil:

Heat up a plate of steel with a torch and drop any oil on it, and they will all run away from the heat and eventually catch fire and burn off....except castor

Castor will run to the heat and eventually form a blob of tar, then turn to an ash which when cool is slick like graphite.....it don't get any better than that.

With engines getting rare and Cox engines being out of production, compromising them by experimenting with boutique snake oils is not worth the risk.
Remember, Cox warrantied these engines and recommended their fuel only, which originally was 100% pure castor with no synthetics added.
