Some Genius obviously came up with that bright idea, om-15 used to be in a nice round tin and impossible to mix up. I did read somewhere that the world is expected to run out of om-15 in 3 or 4 years, there's only one refinery in Venezuela that produces the stuff and we're rapidly running out.
I can see a GEMS here, lets put the replacement oil in Pot Noodle tins or something, that way lineys can get it mixed up with their staple diet!
£25 please.....
