Fuel and lubricating oil

(1/4) > >>

MikeN:
I am building the Bentley BR2 rotary/radial engine to the L K Blackmore design.
With this design, Petrol is drawn in from the carburettor through the hollow crankshaft in to the crankcase where it mixes with the oil  to lubricate the working parts before being transferred to the cylinders for combustion.
The book of instructions says to run the engine on lead free fuel that contains no methanol ( I'm guessing ethanol as well?).
Lubricate with castor oil . Castrol R30.
My question is:
As an alternative, Can I run it using 2 stroke oil and any pump fuel?
I feel this would be more convenient as I recall reading somewhere in the past that Castrol R is a bit messy and leaves unwanted deposits ( but smells lovely!).
Thanks Mike

Roger B:
Methanol and ethanol containing fuels tend to absorb water which can cause corrosion problems, especially when they are distributed through the engine.

Admiral_dk:
Ethanol is part of Normal Pump Fuel  :(

A good alternative is Alkylate Gasoline - sold under a number of names all over the World and often in DIY and Garten centres - for Generators, Lawnmowers, Trimmers and Chainsaws.

MikeN:
Thanks for the replies.
It seems I can buy ethanol free fuel from a nearby boat marina.
However my main question was, can I run this engine with 2 stroke oil instead of castor oil ( Castrol R)?
Thanks

Vixen:
Don't get over concerned about ethanol free. Standard pump petrol will run most engines.

Castrol R will eventually gum up most engines, but it smells great. Use a low sulphur synthetic car engine oil or 2 stroke oil instead.

Mike
