A microalgal organism capable of refining high-grade petroleum. Its scientific name is "Botryococcus ozma braunii". Improvements in cultivation techniques allow the organism to be mass-produced at low cost, raising hopes that it could be a viable biofuel alternative to petroleum. Each kilogram of algae yields 800 grams of crude oil. About 70% of this crude can be converted to gasoline, and about 25% into jet fuel. The resulting gasoline has an impressive octane rating of 96.

OILIX was discovered in 1999 by the Czech scientist Dr. Kio Marv while experimenting with biomass to develop improved agrochemicals. Marv was abducted by Zanzibarland to gain a monopoly on OILIX, triggering Operation Intrude F014.
