RE. FUEL. Y53 / X1555

For demonstration purposes we recommend you to use or try the National Benzole Co's mixture which we believe is half benzole, and half petrol.

In my limited experience I have this to be excellent for starting, slow running, absence of detonation, and increased power.

Naturally it may have some disadvantages such as the presence of sulphur corrosion.

I am asking the Works to examine it, and if you cannot get a full supply I think one can of this, and one can of petrol, say Shell No.1, would give very good excellent results.
