For those of you who like old oil cans, here's a rare one - a can of Eon E-11 'synthetic motor fluid':

I think if you researched it, you would find that this can is a really, realy early one (ie 1970-1972), b/c if you look at the April 1976 PS article on synthetic oil, they have a picture of Eon E-11, and it looks very different - much more 'modern' looking, relatively speaking. Also, this isn't called 'engine oil' its called 'synthetic motor fluid', which is what Conoco Polar Start from 1968-1970-ish was called.
