Dla angloznajacych ciekawostka:
"Back in 1998, Mobil filed suit against Castrol for falsely advertising
Syntec oil as synthetic, when in fact it contained a highly hydroprocessed
mineral (Dino) oil instead of a chemically synthesized basestock. Due to the
amount that the mineral oil had been chemically changed, the judge decided
that Mobil lost that suit. As a result (except in Germany), any oil
containing this highly hydroprocessed mineral (Dino) oil (currently called
Group III basestock by the American Petroleum Institute) can market
themselves as a synthetic oil. Since the original synthetic basestock
(polyalphaolefin or PAO) costs approximately 3 times as much as the Group III
basestock, most of the oil blenders switched to the Group III basestock,
which significantly increased their profit margins (the price of synthetic
oils didn't drop, as I recall, to accommodate this cheaper basestock, which
makes up >70% of a bottle of oil)."
