This is good but... what does "synthetic" mean? A lot of the oils sold as
"synthetic" in the US are not in fact made from synthetic base oils at all,
just very highly purified ones.

Don't know about the USA - but generally we get the same product in
Canada - and anything advertized as synthetic IS synthetic - but there
are several ways to synthesize a lubricant - including from
feed-stocks derived from petroleum - such as natural gas.

Yes, your labelling laws much more closely follow the EU laws than the US
ones in that regard.
