On an uncharacteristically serious note may I reccomend a cheap chainsaw lube. Contains 'non-fling' additives and is cheaper than bike chain lube. Mid Wales residents can get it from Charlies.
Engine oil can be a bit thin.

Agreed, but not living in Mid-Wales I've no idea whom "Charlies" might be!
Alternative is either EP80 or EP90. Used engine oil is last resort and I don't like semi-synthetic/synthetic polymers on my back tyre or the swarf that it may contain. Definitely played havoc when used on chainsaw chains and pumps, if the contract payments were late coming through. Often resulted in excessive wear between the plates/rivets and potential scoring to the pump plunger and bore!

"Nowt worse than having yur plunger badly scored in the bore lad!"

Toodle pip and 'Thanks' again 'johnr', Bill.
