I thought the word 'viscous' would be a better alternative than 'sticky'. Especially as your speaking of oil in general terms.
Oil is a viscous liquid of brown-greenish colour.

Squeaky, I have noticed that the author uses both terms separately 'viscous' and 'sticky'. I guess they mean more or less the same.
Viscous (thick and sticky), according to my Oxford Advanced Learner's Dictionary..
