I've been told of a local chemist warehouse where they sell castor oil. What kind of oil am i expecting to buy for mixing fuel for our model engines? Is pharmacy castor good, or what other type of castor must i ask for?

Thank you

Medicinal castor isn't recommended because it may have additives in it like sugar, in fact the Merco instructions specifically state not to use medicinal castor. Any castor labelled as AA is fine because that means it's only made by pressing the oil and doesn't have the extra step of chemical extraction which leaves traces of those chemicals that cause the white flakes sometimes seen in certain fuels.

Never heard about sugar in Medicinal castor, in our land are sugar not added in Medicinal castor. Maybe in other land are sugar added for taste..

Don't ask for castor full stop.

Castor oil is bad for humans and also bad for model engines ! Especially 4 strokes. For some reason the older generation of modellers seem reluctant to ditch castor in favour of modern ,clean burning synthetics.

Living in europe, you should be able to get hold of a fuel containing Aerosave fully synthetic oil. Manufactured by the Fuchs oil Co in Germany

This is the fuel you need. The best . http://www.westonuk.co.uk/index_030.htm

I've been using this fuel for 5 years now in everything from an O.S. 10LA to a Laser 240 V Twin. All my engines are spotless inside and out. None of them look like they have been "dipped in toffee".
I don't use any afterun oil. I just run the engine dry at the end of the days flying. The Aerosave oil has the best anti-corrosion properties of any oil. After the winter lay off all my engines are free and not locked solid with castor goo.

Pharmacy castor is usually very expensive atleast it is here and not needed for our model engines.
All you need is first pressing castor oil without any additives, maybe second pressing also is good enough. Not so hard to tell the quality, just look in the oil buttle and if it is clean yellowish or colorless then it is good. I use a first pressing castor oil that comes from India but maybe castor oil is also locally made in your country? I mix this castor oil with Aerosave synthetic oil in 50/50 ratio. There is no need to run any engine dry or using after run oil, simply not needed and not worth the extra hassle.

Marcol,
I dont understand what is wrong with a castor/syntetic blend? Many very well known glow engine manufacturer still recommend a castor/syntetic blend to be used.

My flight instructor has access to this castor and made me a batch of fuel. It seems he's the man to talk to when buying castor :P
Thank you all for your inputs

I pay £17.00 / Gallon for Prosynth 10% nitro. That's a proper gallon not a U.S. gallon. I think that works out at about $30 an imperial gallon.

I didn't say it was cheap , all I said was it's the best.
