I'm sure “篓油 ” 的 “ 篓 ” here is a measure word. Measure words are very complicated in Chinese, they're probably the most difficult part to learn for the foreigners.
In Chinese, there're many measure words, some of them are often used, such as 个、条、双、座、台、本、件、辆、头、位、部、把、只、支、根 etc.
We also have many measure words used not very often, I checked on line then I know that some of them borrow from nouns, they're called 借用量词,such as 一缸水(缸)、一碟花生米(碟)、一箱子书(箱子),so 一篓油(篓)is 借用量词 too.
