Ebay methanol

[marT350T]

I have seen some methanol advertised on ebay that is said to be used for titration for biodiesel. Is this ok to use in a water / methanol mix for my water injection ?

Model shops will sell gallons of very pure methanol which is easy to get and can be bought in samll quantities. cheaper and therefore less pure meth, could cause issues. the model methanol is used to 42K+ rpm everyday in 3.5cc race engines so has to be super stable as the glow plug engines are high compression and essentially semi-diesels.
the best known model methanol supplier is Model Technics in Shoeburyness. most other model fuels are ready mixed (methanol, nitomethane and oils) but Model Technics will still supply pure methanol
